Intel Core i5 & i7 Sandy Bridge Overclocking and Feedback

[johnnyfiive]

Now how about those bios settings ...

Here ya go life.

Thats basically the same settings I used when clocking my board.

I don't have time to fiddle with my camera right now.

Letting it prime overnight, but this has been pretty solid so far.

3DMark 06 run, 570 at default clocks.

Has nobody else upgrade to SP1 and got the latest build of LinX? You're not really doing a max stress test w/o that setup.

Just a quick 3 min test on Super PI / Prime95 / IntelBurnTest / LinX

Super PI - Max 40C
Prime95 - Max 61C
IntelBurn - Max 62C (test finished before SS taken)
LinX - 72C

10C difference seems pretty significant, main reason I backed down from a more aggressive clock

*edit, pics auto resized but still legible.

 

[johnnyfiive]

IBT, Prime, etc. No problems. I'll run SP1 and LinX tonight if i have some time.

 

[johnnyfiive]

Actually need 1.36v in bios to get 4.8 linx stable, but 1.35v for prime95, intel burn test, and pretty much anything else. Not sure why linx needs more voltage?

 

[Nailezs]

linx and ibt stress the chip more. i've seen a lot of OC's be stable on prime but unstable on linx/ibt. i dont even know why people use prime tbh

+1. Priming for hours and hours is just not needed, and can cause more harm than good. Actually, I've never had a system BSOD after it can pass IBT on High for 10 passes on any platform, so I see no need to stress any higher.

Here's my most recent run. Took the screenie before the test stopped to show active load temps and clock speeds, since I have speedstep enabled. One odd thing to note is that Core 0 is like 10c lower than the rest of the cores on load. I'm not sure why. I've reseated and applied new paste 3 times with the same results.

 

[Nailezs]

impressive temps, paul. that venemous-x seems to do well for you

Exactly why I don't normally prime or linx. ITB is usually more enough to confirm stability.
BTW, I'm at 5GHz - 1.42v BIOS, 1.4v idle, 1.43 full load during LinX, 15 passes completed so far. I'm pretty sure this is "stable" enough. Already passed hours of prime, and many ITB runs.

Normal. All 11 cpus i tested where exactly the same, 1st core about 10c lower. If one would have had "normal" temps across all cores I would have kept it.

That's totally normal, what alot of people aren't doing is using an AVX enabled LinPack. If you do, you'll notice when AVX kicks in your temps spike 10C higher and your GFlops pretty much double. A 5Ghz OC is totally fine if you DON'T ever plan on using anything with AVX. As a side note, you need SP1 to start with or else no AVX.

Just an Edit the one sensor being 5 or so C higher is normal too, I've seen this on every Sandy Bridge I've had to assemble so far, I think, and this is just a thought, it has to do with the temperature monitoring to help throttle down so you don't screw something up. Like an extra safegaurd. I go by the other 3 temps as being normal and haven't had any issues yet.

Very nice voltage..... as far as I am concerned the cut off for passes with IBT or LinX is 20. I have had systems crash with 10 passes or less. But I have never had one with 20. It doesn't just seem to be me. When first learning to overclock I Googled the correct amount of times to run IBT or LinX. I saw everything from 50 times to 5 times.
But the general agreements across the net at this forum and others seemed to be 20 to 25 times for stability. Followed by a hour or two of gaming. (When ever you have time) Unless run your PC 24/7. In which case people suggested 20 runs of linX followed by a few hours of Prime 95

 

[PaulieG]

Normal. All 11 cpus i tested where exactly the same, 1st core about 10c lower. If one would have had "normal" temps across all cores I would have kept it.

It's funny though, as 2 of my previous chips only had a 4-5c difference b/t core 0 and the rest of them. Good to hear it's common.

I did say "about".

Personally, I'm of the opinion that this is the core nearest the GPU, and as such it has a much larger area of IHS where it's heat can spread, vs the other three all smushed together near the edge of the IHS, sharing the same area of IHS.

Anyway, it's definitely normal for that one core to show lower temps, 100%.

I think your opinion is most likely correct. There, I said it.

Looking good. You're about at my absolute max load voltage on a 32nm chip, and that is for benching only. Honestly, I'm leery at anything over 1.375v for 24/7 crunching.

 

[johnnyfiive]

Thats only to pass linx paulieg. At 1.38 (bios) - 1.39v (load) it passes prime, ibt, no prob.

 

[Frizz]

Just finished finding a stable clock on my 2600k. 24/7 settings will be the image below

4.5ghz @1.30vcore

This chip can obviously go much higher but if you look at the temps, you can see I am a bit limited with cooling. My temps are everywhere :S

 

[Fitseries3]

anyone here other than me have a NON-K chip?

 

[heky]

Just bought a MSI P67A-GD65(B3), but will have to wait 2 more weeks for my 2600K, will chip in my results when the build is complete.

 

[johnnyfiive]

fits with a sb chip that doesn't have an unlocked multi... wth?

Well for a start you don't have to disable any of the c-states. SB actually work very well with speedstep enable, c states etc.

Change that, pls. LOL. try about 145w for 4.6ghz or so.

Key stuff, there. Play with it a bit, I'm interested in seeing what people come up with.

Thing is though mine is registered in AMPS.... so what should the setting go to then???
