Superpi Benchmarks

[Sid]

I thought it would be interesting to run a benchmarking thread. It is widely regarded that the superpi test is one of the best for judging raw system performance - so here goes.

I've just copied and pasted this test from another forum:


The only way to really do any form of results thread, is using screenshots of programs such as CPU-Z and other such programs.

Rules
You must include a screenshot for your result to count, there are many places to upload it, photobucket.com is available for free etc.
You must use the linked version of SuperPI which is linked in this thread, *nix users: you need to run Wine to get it to work.
Take your screenshot before you hit the \"OK\" button where it says \"PI calcluation is done\" because it's possible to edit the numbers which are returned in the main program view.
Please include the following information about your system:[list:d35466b5ef]
Processor
Motherboard
Cooling
Memory, timings, and dividers (this information can be found out using CPU-Z)[/list:u:d35466b5ef]

CPU-Z

download (http://www.cpuid.com/cpuz.php)

CPU-Z is a freeware that provides some information on your system :

* Processor name and vendor
* Core stepping and process
* Processor package
* Processor current core voltage
* Internal and external clocks, clock multiplier
* Partial overclock detection
* Processor features, including supported instructions sets.
* L1 to L3 cache information : location, size, speed, technology.
* Motherboard information : name, vendor, BIOS, chipset, memory, AGP.
* Memory information : size, type, timings, specifications.

Super-PI

download (http://www.drunken-student.co.uk/dl/super_pi_mod.zip)

This program tests how fast you can compute pi to x number of decimal places, for the purposes of this thread, we'll use 1M decimal places.

Run Super-PI and compute PI to 1M decimal places, then start up CPU-Z and take a screenshot of your desktop and trim it down to size so that you still have your desktop in the background make images no larger than 1024x768 please, anything larger please post as a link. Also post some system specs (CPU stock speed, overclocked speed, vcore at that speed & stepping/week number (if known), RAM, fsb, voltage & timings (if known), motherboard, cooling and temps)

If you get an error in computation of PI, it means your system is not a stable overclock, as it's making computational errors, keep trying til you get it to run without any errors.

I'll keep the table updated as people post more times.

[Sid]

I'll get the ball rolling:

Not optimized this at all, yet. Still had lots of services and background programs running. My RAM seems to be slightly faulty too, so I need to return it at some stage. Eventually I hope to get sub 30s with this.

YegaDoyai had once told me that CPU-Z will only tell me horrible horrible lies (because of some of my hardware), shall I get my superpi screenshot and try and get some screenshots from SiSoft Sandra to go with it or will CPU-Z be ok for the purposes of this testing?

I can't see why CPU-Z would be wrong. See how it goes.

[Sid]

Nice times Yega. What memory have you got so I can add it into the list.

Is it a 3:2 memory divider you're using, yeah? How does that compare with using a 1:1 at slightly lower FSBs for you? Looks like a pretty nice CPU you've got there. :D

[YegaDoyai]

The memory is Geil Value 1GB Matched Pair 2.5 3 3 6

It runs stock speeds at cas 2 1T
Has a maximum speed of 233 @ CAS 2.5 2T
And maximum Speed of 225 @ CAS 2.5 1T

The divider is indeed 3:2 I tried just vanilla OC on the FSB to get FSB 233 CPU @ 1864Mhz but the difference to stock settings is minimal. The faster the CPU in this test the better the performance. With a single memory channel and half the L2 cache that the big boys have (actualy only a quarter of what you have Sid) the memory timings are less important to a Sempron than they are to the real A64s so I just went for strait clockspeed.

I have been reading more on memory timings and skew values etc but all that will be in vain unless I can keep my NB cool as that is currently limiting my OC. I suspect the processor could go above 2.6 as I have got it to boot at that but the NB was melting.

The other bugbear of the Sempron is that all multilpliers are locked. :(

And thank you, it is a nice CPU.

<strokes PC>

CPUz lies about Sempron CPUs past my one and as Fyndirs A64 does not exist when I told him CPUz was lying I thought I was being accurate. However since then I've found that Sandra is wrong and CPUz is correct for his machine.

Alright, fair enough, I'll get the pi thingy and CPUZ going once I'm at home. =)


EDIT:

Assuming that I'm awake enough that I did this right here it is, running at all my standard settings with whatever this machine decides to launch on startup.

http://img.photobucket.com/albums/v601/Fyndir/SuperPiCPUZ.jpg

Then again, if I go to my task manager when superpi is open and tell it to give it realtime priority..

http://img.photobucket.com/albums/v601/Fyndir/SuperPiCPUZ2.jpg

A slight gain. =O

[Sid]

Fyndir: The RAM you bought is quoted at 250MHz (500DDR) stock. You should really up your FSB to 250MHz at least. Even if you were running it with a 9x multiplier - which would give you 2250MHz (only 61MHz more than your current settings), I imagine you'd see a notable increase in system performance. A64s love huge memory bandwidth.

Where are the rest of you guys' scores - I'm waiting for Strings and some others to come along and beat mine :lol:

[Phizz]

Erm....... no way I'm doing this yet. Just put me at the bottom. :-(

That sounds like exactly the kind of thing which I would manage to set fire to my computer while attempting. =(

It won't do any harm to your computer to have a mild play around. If you weren't going to bother with overclocking you could've saved about £100 by buying cheaper RAM.

Try to read a few articles on overclocking (http://www.hothardware.com/forum/messageview.cfm?catid=19&threadid=14008&enterthread=y) so you get the right idea. That linked page should teach you the basics that you need to know, such as the importance of the FSB, multiplier and voltages.

I have read some of them already, what was worrying me was "2. Properly cooling your hardware to prevent damage and get better overclocks"

From my understanding of things I'd want to upgrade some of my fans before looking at overclocking.

[YegaDoyai]

NOpe your airflow will be fine, give it a shot. If it starts to overheat it will tell you long before anything fails. The main reason you should upgrade your particular HSF is that it is LOUD!

CPUs don't run as hot as they did a couple of years ago. Stock Heatsink/Fan is usually sufficient for a decent bit of overclocking. You should at least run 250FSB with a lower multiplier - that won't put much more strain on your CPU than stock speeds. Have a go.

[YegaDoyai]

Just noticed you have me down as a 9 times multiplier, sadly it is just an 8*.

Would be 2835Mhz otherwise, damn that would be sweet.

Oops, sorry - my bad. Fixed now.

[YegaDoyai]

awwww, now it's too small to read

[Sid]

awwww, now it's too small to read

Yeah, trying to fix that - my image host seems to be resizing it automatically :roll:

I notched up my multiplier to 10x and lowerered the FSB to 260MHz for another run, just there.

http://img.photobucket.com/albums/v213/craigjohnstone/sidsuperpi2.jpg

Managed to cut my time down quite a bit.

EDIT:

Cancel that, got it up to 270x10 and got this:

With a little more work and after I return this RAM, I should hopefully be able to get FX-57 speeds, at least.

That's actually a pretty good time for a 3200+ Barton. The best overclockers who really push their machine on stripped down windows installs usually manage about 40s flat.

Yeah? That's good then. I could push up the mutiplyer a little to 12 and maybe try running over 200Mhz FSB. However, when I've tried in the past it would get unstable. Maybe seeing as I've got my memory timings nailed down, I could give it a try again. Then again, if it ain't broke, don't fix it.

[YegaDoyai]

that's some pretty decent RAM you have there Sid, nice OC. I wonder what mine would do with uber RAM like that...

[Fyndir]

that's some pretty decent RAM you have thier Sid, nice OC. I wonder what mine would do with uber RAM like that...

In theory I could possibly push my machine to be almost as good as sid's for this benchmark, since we have the same RAM and the only difference I can see is the processor and the fact that I don't really wanna OC my machine atm.

I've seen skt939 venices do low 30s (actually I've seen a watercooled 3200+ do 28 something) although I'm not quite sure how the 754s compare. Bear in mind, although your CPU has the same stock clock speed as mine (2.2GHz) - mine is a San Diego (same line as the 64FXs) it has 1MB L2 cache and I'm running it on a DFI SLI-DR which is probably the best performing motherboard around at the moment. That and the fact that San Diegos are generally good overclockers.

How come you're not keen to have a go at overclocking? As I've said before even if you don't want to overclock you should still up your FSB to 250MHz and lower your multiplier - in order to take advantage of the RAM you bought.

Anyway... Where's everyone else!? Surely there's a few more people that'll have a go?

Actually mine IS a 939, YegaDoyai counted. =P

I'll admit my motherboard may hold me back a bit, but I can't imagine it would be making a massive difference.

The main reason is that I don't have the money to replace ANY of this gear, if I piss it up and break it by accident I'm fucked, also the whole shorter lifespan of hardware problem is a worry for me.

[Sid]

Actually mine IS a 939, YegaDoyai counted. =P

I thought yours was a 3400+ CPU? AMD never released 3400+ 939s.

The main reason is that I don't have the money to replace ANY of this gear, if I piss it up and break it by accident I'm fucked, also the whole shorter lifespan of hardware problem is a worry for me.

With my recommendations - you wouldn't actually be overclocking any component at all. You'd be running both your RAM and CPU at stock values. Hence no issues with shorter lifespans or breaking.

[YegaDoyai]

He is right Sid, it is a 939 3400+ The reason I thought it was a s754 is that Sandra reported he was using an 800Mhz HT bus and they never released a 3400+ in s939. However having removed the chip and seen the socket I can confirm that it is indeed a fully fledged 939 he has.

[Sideshow]

Things not to say on a first date: Anything in anyones sig block in these forums. Seriously.

[YcMing]

ahh.. is this program doing alot of iteration ti compute pi, and see how fast your computer can handle it ??? I think after 9 iteration, your computer willl have to calculate numbr with like 100,000,000 integers???

That is a very good idea :0...

[YegaDoyai]

Just to screw up what Sideshow says.

It is a 3400+. =)

Welcome to the world of Fyndir, no matter what I do SOMETHING WILL BE STRANGE. =D

sid, another reason is laziness, I'm currently slowly but surely moving all my games (uninstall..reinstall..wax on...wax off..) over to my new drive, which means I might need to re-borrow some games from the next LAN, maybe AT the next LAN you can slap me while my computer is starting up and change the settings yourself. =P

[Sid]

He is right Sid, it is a 939 3400+

Sorry, my mistake. I didn't think AMD ever released these but they seem to show up in a few pre-built systems or something? My bad.

[Viper001]

My new dual core centrino laptop gave some interesting results. The second screen shows that while it was running, only half of the CPU(s) were being used. I guess this is something to do with the fact that only some types of true multithreaded apps can support full speed of both cores. Luckily I've heard that most games these days do utilise dual core quite well, and directX 10 will have even better support. Anyway even at half load i'm pretty happy with the results. I still would have preferred an AMD though, but what the hell..
Centrio Duo... wooo!!! http://www.intel.com/sites/corporate/pix/badges/centrino/d_76.gif

I might tweak the RAM a bit and see if that improves the speed, its not running at optimal quite yet.

Nice time there. As far as I've seen the newer intel CPUs tend to beat AMD when it comes to this. I've seen a few times in the 24-25s region with people on Intel P-M 740s + 745s on air cooling.

Exactly that, AMD never released it properly (if you look on their site and their processor lists you can't see it) but it turns up in some prebuilts.

Which suits me quite nicely. =D

Intel CPUs have long pipelines - making them perfect for encoding video and calcualting pi to lots of digits.

AMD processors have less of a pipeline, which makes them great for heavily branched code - games and stuff.

[/gross simplification]

I'd rather have an AMD in my machine at home (games) and an intel in my desktop at work. Different tools for different jobs, eh?

[LastChanceHotel]

Mmm.

Just had a go with my new GeIL Ultra-X RAM (thank you very much Overclockers Returns Dept, for giving me RAM worth £110, rather than £60!), and got some shiny results.

http://tunnel.beoch.net/29sec_superpi.jpg

In hindsight, such a high Vcore wasn't really neccassary, as it didn't translate into much of a performance increase. it ran beautifully at 1.50v.

The proc is an Opteron 146, CABNE 0544 EPMW. Cost? £143 from Ebay.
Motherboard is the infamous DFI Lanparty UT Ultra-D, with a BigToe hacked bios.

The RAM is running at 2.5/3/3/6 @ 233.4Mhz, timings loosened a little from 2/2/2/5.

Sweet jesus, this stuff eats volts... 3.2V Vdimm!

http://tunnel.beoch.net/ram2.jpg

I have been able to kiss 3Ghz with this thing (2.975Ghz), but only from cold, and with temps of about 15-20'c ambient. It's certainly convinced me to continue with my immersion oil + phase cooling project.. Mmm, Opticool...

Here's some of the more advanced timing information.

I noticed there's been a couple of new results uploaded that I've missed. I've updated the table accordingly.

Nice time LastChance. Would you mind running it again with the modded superpi linked to in this thread? (it gives precision to 3 decimal places).

I was curious as to what benefits BigToe's modded BIOS allows?

[YegaDoyai]

Tis not the season to be overclocking. To warm in the ambient temps but even so... I have been thinking about replacing my passive north bridge, like i said in my post the NB gets very hot at 300+FSB and I need to cool it better to get a higher stable OC. I think that the new passive cooler from Zalman is very nice, but probably not much better than the one I have. Any suggestions? Remember I have the big 120mm Zalman flower cooler so there is plenty of cool air available for a decent passive cooler.

[LastChanceHotel]

Zalmans look shiny, but in my experience they're Stock Heatsink + 50%.

Go watercooling, or if you're chicken, the SP-120 is working well for me.

Yeah, summer's a pain. Makes me wish I had a cheap oil I could use at -20... Although vodka works, it's conductive.

I was well pleased with my time - I'll have another shot when it's really cold with the modded version.

37.9s

managed to squeeze a further .5s off my previous best taking me to a sub 38s time. With mem that would do 1:1 i could get below 35s easy, maybe even challenge the big boys lurking around the 33s. Note that the clock and mem timings are the same for my previous best but with tweaks to other parts of the bios and some minor adjustments to voltages for stability.

Our heating has broken in the flat, with all fans off in my machine (CPU fan @ 900rpm) I can't get my internal temp above 30degrees. :(

Upshot is stable OC is easy. :)

It's not like anything AMD has can really compete with the core 2 duo :P

[Tiberio]

Sry Lastchance, get yourself a C2D and we can have a battle of the giants:P
I don't even want to imagine what the E6600 can do when OC'ed:)

[YegaDoyai]

well tib, the latest E4300 can get to 3.73 on stock cooling, so yeah, i think you have some headroom.

Technically your entry shouldn't have counted as it was using a different version of superpi, but I thought I'd put it in anyway :)

[Captain_Caveman]

Having just looked through this and many other posts (I am weighing up building a system round the Lian Li case I finally found motherboard mounts for) and I noticed your timing on your RAM is quite high Pixie. You are not even overclocking the E6300 much yet your 4-4-4-12 RAM is sitting on 5-5-5-15 timings. Surely it doesn't need slackened that much.

[YegaDoyai]

Where did Pixie say his memhad those timings? AFAIK that is his default timings.

[DAve]

well tib, the latest E4300 can get to 3.73 on stock cooling, so yeah, i think you have some headroom.

That's the gigahertz rating, not the SuperPi time. Right? :shock:

Yeah, otherwise I think everyone and thier dog would be buying one right now.

Hey, Tiberio: I missed your screenshot when it went up and it seems to be a dead link now - if you re-host it somewhere I'll stick it up.

I've found the real reason to upgrade to C2D or to C2Q - video encoding!

http://www.pausegaming.com/galleryimages/img/transcoding.JPG

So either I'm going to enlist the help of the veritable farm of servers I'm currently managing (32 of them - 16 are core 2 duo's), or I'm going to need to build a kickass machine.

Intel are selling core 2 duo's with 16MB of cache, and multi-CPU boards are also available. so, how about four of these:
http://www.pausegaming.com/galleryimages/img/xeonquadro.JPG
one of these:
http://www.supermicro.co.uk/snatch/supermicro.com/a_images/products/X64/E8501/X6QT8_spec.jpg
chuck in 64GB of Kingston Value ECC DDR2 memory... a snip at just £458 per 4gb stick...
http://www.techstore.co.uk/browse.php?a=p&prodLineID=44080

and throw it into a Quad Xeon Supermicro case -

http://www.supermicro.co.uk/products/chassis/1U/818/SC818S+-1000.cfm

put a pair of 73gb 15k RPM Cheetah drives in there too...
http://www.ebuyer.com/UK/product/95614

and you've got a server comparable to Colossus.

Best of all, you see that black little slot near the end? That's a PCI-E 16x slot. :D

Total cost? A snip at just £23,982.68. :O

I should stop looking at Xeons really, it makes me want to spend money. :(

[Muppet]

When i get my PC back up and overclocked again i'll post my results.

Had a E6300 running 3.2ghz (460x7) on air with Geil PC6400 running 4-4-4-12 @ 920mhz (mems good up to 1000mhz). Super pi 1mb was 18.2s.

As for Pixie, his timings for anything up to 800mhz (400fsb using a 2x multiplier) should be 4-4-4-12 - since thats what GeiL advertises. Above that its hit and miss whether your ram can hold onto cas4 otherwise its a drop to cas5 above 800mhz.

Cool, just in case anyone else is interested the nice memory mentioned here is on this week only at OCUK. £135.11 inc VAT!

Might have to scrape some pennies together for that.

Had a little shot at overclocking there with my newer memory - was thinking I could probably quite easily beat my old 31.16 I got with my dodgy memory, but the CPU doesn't seem to like it. Superpi doesn't run past 2500 / any FSB. Hrmmm.

Memory: 1gb 225 Mhz 3-3-3-8

[YegaDoyai]

Nice work, very brave in a lappy.

[Captain_Caveman]

Not quite so scary on a turion machine. They seem to have an auto-throttle. If the heat gets too hight they just throttle back from 9x multiplier to the 4x multiplier and loose the heat. So it is finding a balance where it doesn't need to throttle back thats the fun part. :D

[YegaDoyai]

Nice, just so everyone knows can you just tell us again how much that processor costs?

[Strings]

Caveman got a new PC? Nice.

[Captain_Caveman]

That would be just over the 100 pounds.

[YegaDoyai]

For the uninitiated, the E6600 you see in tiberios computer costs a whopping £200 and is slower than this clocked E4300!

Overclocking, it's fun 'n' it's easy. You're gonna learn all about it.

Regarding clocking the C2Ds, it appears that 800Mhz is not just the sweet spot for the memory but any increase over that speed sees less and less return per pound spent. Save your money and go for the lowest latency 800Mhz memory you can buy.

[Tiberio]

You're right Yega, but I don't see a point in oc'ing when my pc chews through everything I throw at it.
Might try a little at some point, the 6600 should overclock very well even on air.

[Muppet]

3.8-4ghz stabe with a good mobo. Friend has one on air o/c @ 4ghz with a P5B.

[Tiberio]

Wow Stuart, that's damn impressive!
Allright, next time i've got money I will buy a good cooler and get to it if that's the kinda results I might get:-)

[Captain_Caveman]

Those results are impressive, however watch your heat levels, the C2D's don't like much above 50 degrees. Really reduces their life expectancy.

Its Intel's SpeedStep technology. For overclocking, clearly has to be off :p

On bootup, if you dont know what key you press to enter the Bios menu, mash the F'keys.

When you get into a blue menu area (bios) look through the different menus till you find an option called "Intel SpeedStep" or similar and set it to off/disable.

[YegaDoyai]

ok, for the newbies and the new machines can we please get this done? It's not an epeenor test it is relative measure of performance. This way we'll know what we are spending to get a certain level of performance and if our machine is the decrepit crap hole we think it is or just badly configured.

hopefully Sidalicious will keep this updated too.

I was just checking to see if there was perhaps a multi-core version of Superpi but it doesn't seem that there is. Now that most of the club have multi-core CPUs, we'd probably be better moving to something like Cinebench 9.5.

[YegaDoyai]

The thing I liked about SuperPi was that it was CPU/MEM dependant and did not rely on the graphics subsystem. If Cinebench is the same then sure otherwise we should look for a numbercruncher that is multi core aware.

Can you include a link to the table if you do get it back up and running. I'd really like to see a column for superPI score divided by CPU speed (megahertz rating), giving a kind of "lie rating" to a particular CPU family. Are the core duos really twice as good as single cores?

/me ponders geeky thoughts.

Ok. That's the table updated now. If I've missed anyone's time, please let me know and I'll add it ASAP.

DAve: I've included the Excel file in a ZIP file attached the first post. I'm not exactly sure of what you mean, but feel free to add any extra information to the table that you think would be interesting and I'll upload that instead.

Memory dividers, memory timings and cache size are still quite a big factor for Superpi - not just the raw clock speed. gor's Core Quad actually beat a faster-clocked Core Duo despite SuperPi not being multi-threaded which I can only assume means that the extra cache on the Quad-core is making quite a lot of difference.

*sadface* time to do some OC'in

[Bluepixie]

w00t! That's beasting! I was impressed with my time but now..........:(

Anyways, turns out that my new BIOS update has really opened up my OC potential. Check it out!

21.42s

MSI i975X Power Up! 2.1 Rev. C0 375MHz FSB
BIOS - 2007/10/08 v7.7
Intel Core Duo E6300 2.62GHz - 1.368V - Zalman 9700
Geil PC2-6400 2GB[2x1024] (5 - 5 - 5 - 15) (2.2V) (1:1)

http://www.pausegaming.com/niall/alita%2021.jpg

I reckon with better cooling I could push it a bit more, but I think it's the limit for now. Still, I'm a little confused because before I got a time of 22.677s with only these settings:

MSI i975X Power Up! 2.1 Rev. C0 311MHz FSB
BIOS - 12/07/2006
Intel Core Duo E6300 2.1GHz - 1.184V - Zalman 9700
Geil PC2-6400 2GB[2x1024] (5 - 5 - 5 - 15) (1.8V) (4:5)

http://www.pausegaming.com/stuart/galleryimages/committee/Alita.jpg

The 4:5 ratio on the memory is speeding things up a bit but I can't replicate that time with these settings on this BIOS. Maybe the new BIOS allows for a more stable setup but (i.e. higher OC'ing) but overall reduced speed? Or maybe my XP install is causing slow down despite running SuperPi in real-time (well as real time as it gets on Windows). *shrugs* who knows.

Plus, I set the voltage to 1.4V in the last set of tests, but CPU-z only reads 1.36V, is this normal with the C2D?

[DAve]

DAve: I've included the Excel file in a ZIP file attached the first post. I'm not exactly sure of what you mean, but feel free to add any extra information to the table that you think would be interesting and I'll upload that instead.

I've calculated the spreadsheet - the columns I've calculated for my own amusement are a measure of the speed per MHz of the processor family.

"clock / score" is a measure of how fast the processor is working compared to the stated speed. Clearly, file2fly and core2 duos are for the win.

"clock / score / core" is a measure of how fast the processor is working compared to the stated speed taking into account the number of cores. It's a different ballgame here, with Jan taking the prize thanks to the amazingly overclocked opteron setup. Core2s are biting at his heals.

Interestingly, it's quite close [1], taking this as a measure. Core2, semperons and AMD processors are fairly even. The Megahertz myth seems to be a lie.


clock / score clock / score / core
125.6 Core Duo 62.8
144.0 Core Quad 36.0

98.4 opteron 98.4

[1] excluding the core 2 quad which doesn;t seem to be optimised for that program. Are you sure that it's using all 4 cores g0r?

[Sid]

DAve: Superpi only uses one core. gor could run 4 superpi calculations simultaneously at the same speed of 18.752 whereas Fil2efly could only run 2 @ 16.899 and Jan could only run 1 @ 29s.

Earlier in this thread I'd suggested that we move over to a multi-threaded benchmark since most people are now using dual-cores and some quad-cores, but I forgot to have a look for one.

I've updated the attached table and I'll try to update the screenshot as soon as I work out how to take a screenshot that wide.

I've never been able to get a good overclock with an 8x multiplier.
Is less volts the key for a high fsb?

[Bluepixie]

Nice, looks like you've got competition noodle! :p

Which voltage do you mean? The core voltage could be increased, you were running at 1.45V which is still within the limits of the 65nm fabrication, and I've heard that you can push it up to 1.5V without much fear. Might not be that stable but you never know. I've read that people have tried 1.6V and even 1.8V but only using water cooling and such like. Granted it's not good for the chip but it's up to you. If you increase the vcore you might be able to clock it a bit faster but you'd probably have to tinker with the memory timing and increase the voltage there too. What cooler you using? What voltage you running the mem at and can you adjust the northbridge voltages with that MB? I can't do it on mine. :(

[rockstar]

I think i read something somewhere that said to lower the vcore a tad to get a better fsb. Maybe that was rubbish. A lower fsb with a 9x multiplier seems to be working just fine for me at the moment.

The vcore is actually sitting at 1.485v. It's the highest i've had it, but its unlikely to boot any lower. And i'm reluctant to go any higher, just in case.

My ram's running at 800Mhz on a 1:1 ratio at 2.2v, and I've never tried changing the timings. It's something i'll need to read up about.

I've attached a screen with all my settings and stuff. The NB & SB are increased a little but i'm never sure how much is still safe!

Normally running at 3.2Ghz (356x9), with my ram at 1068Mhz 5-5-5-18.

And as for cooling, the mighty Arctic cooling Freezer 7 Pro!

Gah! I'll need to wait until after my exam to do some more tinkering or else I'll end up not studying at all! The previous oc used 1.35vcore so I have a bit of headroom left.

I hope you two don't push each other's rigs to the point of meltdown. :)

I think it should be noted that Barney is doing his clock with stock voltage and air cooling. I'm convinced that he could easily push into the very low 10s and probably into the single digits with water cooling.

thats something i was thinking of while driving down the road. i may go ahead and do the case mod i was thinking of and while im at it perhaps go for water cooling

Ok, I'll start a new thread, possibly here, possibly on my own forum but soon. I'm looking at free multi core benchmarks, so far this one looks good:

Hmm it seems not to hot on detecting the actual speed your cpu is at, claims mine is 3.3GHz when its actually only 3GHz

[Sideshow]

How do you know it is 3Ghz?

[Fil2eFly]

detecting myn fine. stock it runs at 3003 and the clock was to 3600, so all looks fine

[Fil2eFly]

oh hot jst ran Super PI on my laptop and got 33.250s

Ok, I've given my little C2D a shakedown overclock and stock it gets about 32sec and basic overclock gets about 22 sec. It's only a 2160 so getting down to the mid teens is unlikely especially considering I'm on stock air with limited MOBO tuning options. However I thought I'd quickly throw up my weekend game plan for OC:

First test the memory speed:
In order to do this you need to ramp MEM speed without affecting the FSB or CPU speed. In some MOBOs this will not be possible but for any OC centric build this should be possible. My memory is rated at 800 @ 5-5-5-15 so I think about 820-830 at those speeds is likely to be the most I can get out of it. I might try 850 @ 6-5-5-16.

Purely for OC purposes I will also try my working stick of OCZ 800 @ 4-4-4-15. which might get to 850 @ 5-5-5-15 at max volts.

Next is the FSB:

In order to push your FSB high set the CPU multiplier as low as it will go, set the MEM divider so it is staying at or below rated speeds and then just keep cranking on the FSB and volts until you find your max. Most MOBOs have passive cooling for the NB and they get toasty. I'm pretty sure that the most effective upgrade for an overclocker is to replace the NB cooling but that is speculation. I already know mine posts at 350 (stock 200) so I'll see how it goes.

CPU:
You know how fast your MEM and MOBO go, so how fast does your CPU clock? Well I'd be tempted to try the max OC you can considering the results of your above tests and just ramp the CPU voltage till it works. Extra cooling is not just recommended for this phase but frankly a requirement. Your CPU + MEM + MOBO all chucking out more than normal heat is going to require you to get rid of that heat for stability. Desk fans + side of the case being off are favorite temporary measures.

Next week:
GPU overclocking.

[neogramps]

thanks peter, i was just about to ask you about oc'ing - again. got a new CPU cooler coming and I'm hoping to squeeze a bit more performance out of my cpu till i replace it in a few months

[neogramps]

Ok so I've tried my first overclock over the past 2 days - I got on ok, but I'd been relying on some auto features of my mobo, and although I got a prime95-stable OC, it was unstable in games, so I went back to stock to start again.

I was a bit confused as my bios seems to have weird naming conventions/options which meant that what people were saying didn't relate to what i could do, so I looked up a few pages on my specific hardware and I read this (http://www.pcper.com/article.php?aid=192&type=expert&pid=3) and I decided to try and follow its suggestions, along with using some stats i'd read from ocz on my memory. The things which had thrown me were: the FSB is called the CPU Frequency and my board doesn't apply this to memory at all - you just set the mem speed at whatever you want.

So, my results so far are this:

Stock: CPU@2GHZ(200x10), Ram 2.5-3-3-6 2T @ 166,2.6V - SuperPI 1M - 43.782s, 3dMark05 - 10,018
OC: CPU@2.4GHZ (240x10), Ram 2.5-3-3-7 2T @ 200, 2.7V - SuperPI 1M - 37.094s, 3dMark05 - 12,713

During my first OC, I had different RAM timings and was running the RAM @ 200Mhz - but when I went to do it the second time, with the new timings (which are from OCZ), for some reason it wouldn't boot. So I tried to see if it would boot at 166 - which it did - but when I checked it in Windows - it was actually running at 200? I have doubled checked, and the bios says it's at 166, but it boots as 200? During my first OC i had the ram on auto so it scaled to the FSB - 200:166, 220:180, 240:200 etc, so it had previously worked set at 200, but if i explicity say 200 it won't boot. edit - the link above actually explains this as a fault in the bios as he mentions setting to 333 to get 400, weird.

But, this OC is stable so far - done a few hours of prime95, a memtest cycle, looped crysis benchmarks and played wic and COD4 (which had previously been unstable). No noticable temp increases. I'm fairly confident this OC will be ok, but only time will tell.

Okay, I can't be botherd working this out exactly but what you are doing is setting the RAM multiplier. The ram speed is a function of the front side bus. The memory controller is built into the AMDs and is completely linked to FSB throughout the range regardless of MOBO. You should have settings for 133, 166 and 200. If you are very lucky you might get something above 200 but these will be unsuported by everyone. To get my tasty overclock on the Sempy I was running an FSB @ 350 and a 133 multiplier to give me an effective 206(?) Mem speed. 240 @ 166 multiplier must equal 200 effective. 240 @ 200 multiplier will try and run your ram at 240. So indeed this will not work for most DDR 400 RAM.

Soooooooo

You know so far that you mem doesn't go much beyond 200, see how far you can get before it keels over at the 200 multiplier, losen the timings to 3.3.3.7 2T if you want. I got 233 with my value ram, but it was pretty good so I don't know what you should expect. Also with my sempy being single channel there was little advantage in running 1:1 for my ram as it was interface limited, yours is dual channel so the optimal time will almost certainly come from a 1:1 ratio (ie 200 multiplier - why you should have bought better ram to OC)

Once all is said and done I think the Manchesters were pretty shit for overclocking unless you gave them extra juice, extra juice means more heat so make sure you keep an eye on temps!

For the Super PI don't bother with prime95. Just run super PI and then reboot to stock, you are not going to get a stable, worthwhile overclock out of that core on anything less than sub zero cooling - from what I read back in the day. :( I can't remember what the desktop version of Jans core was called but I think it was the one after Manchester - might have been a stepping of Manchester in which case I might be wrong.

Didn't you have some nasty screenshots before? Looks like I have amazing powers of prescience to say what core you have without them :)

[neogramps]

As I said I'm not looking for a meaty overclock - it's like practice for when I get a core2 - i'll see about pushing the memory a bit more, but for now, it's running faster than it ever has, and still cool and stable, so I'm quite happy. Oh and the ss are still there.

Back here (http://forum.pausegaming.com/showpost.php?p=27191&postcount=157) I managed a SuperPI of just over 21sec @ 2.7Ghz. I just tried at 3Ghz and got 22sec. My machine is running notably slower than it was when I first installed and ran SuperPI. Interestingly it has actually made a difference to working performance so I'm happy to stick with it regardless of spurious benchmark results...

[Fil2eFly]

still a solid 17secs here all standard :)

[Captain_Caveman]

Damn, I be slipping slightly I am about 0.02 over the 20 second mark now. :D
