getting a stable overclock with S3, EX58-UD4P

[joeblough]

hi everyone,

i've posted a couple of times in the beta bios thread regarding problems with my EX58-UD4P and trying to get a stable overclock which resumes properly from S3.

i found that everything before F9a would not reliably wake from S3 when overclocked. F9a seemed to be very stable coming out of S3, but then i discovered it was failing mprime at BCLK=166Mhz, cpu=3GHz and memory=1333MHz. at first i thought it was only failing after waking from S3 but it turns out it was failing even after a cold boot.

i have 12GB of XMS (9-9-9-24), and i did find that increasing Vdimm helped (it was actually failing memtest86+ without the Vdimm bump) but after that, even though it would pass memtest86+ fine, mprime was failing after 8 hours or so. then i found that it was even failing in the same way with optimized defaults loaded! so F9a seems to be kind of a non-starter.

so this morning i went back to the released F8, with bclk=133Mhz, CPU=2.66GHz and memory=1333MHz + 1.6Vdimm. it was pretty stable until sleep/wake, at which point the machine went completely crazy. one thing i missed though is that i didnt adjust the uncore multipliers. i dont know if the bios is supposed to take care of this when you change the memory multiplier or not.

so now i've loaded F7e and i'm repeating my experiments.

im expecting to end up down the garden path again, so here's the question:

if i want to OC and resume properly from S3, what's the best bios to use? does anyone have a good profile or detailed settings against that bios? i'm interested in ~3GHz + 1333MHz on 12GB of corsair XMS DDR3-1333 memory with 9-9-9-24 timings.

thanks.

Joeblough,

Please add all your Specifications to your Tweak Town Signature. There's not enough information in your initial post to deduce everything that one would normally like to know about your particular problem.

1. Click where it says "User CP" at the top of any page on this forum when your logged in. Or maybe this might work: TweakTown Forums .

2. Click, " Edit Signature " on the left of your Control Panel.

3. Update the following with your own info and copy/paste it all into your new signature:

<<< System Summary >>>
> Power Supply: ________________________
> Mainboard : ________________________
> Chipset : ________________________
> Processor : ________________________

4. Preview and save it.

And then we'll be able to see all your Specifications on every post you make.

And include your mobo rev#, bios version in your signature too. <!-- / message --> <!-- sig --> __________________

thanks, i'll do that. things are looking pretty good right now with F8a with a few manual settings. had one failure in mprime after 10 hours. i'm starting to suspect that i have a bad dimm. unfortunately its hard to narrow down what dimm is bad using mprime.

Cool. After you add specs to ur sig, try and find a BIOS template close to your MOBO and post your current setup.

done. started mprime again and one thread failed right away again. i'm going to run memtest86+ and maybe i can narrow down where the bad memory is. i'll look for a template.

cool.

Here's my Template: (Its too simple for u2 adapt to though. But try and find something similar to use as a "Master Blank Template...", for ur MOBO Make and Model#.)

i have also run with x20 for the cpu multiplier. interestingly sometimes the machine will not POST like this, maybe one out of 5 times. that seems to be the same rate that it will not wake from C3, so the two must be related. also i still have pretty reliable mprime failures, sometimes pretty quickly. one thread out of 8 pretty much always dies. i guess this could be due to bad dram...?

maybe the biggest mistake here is the cpu voltage set to auto? what's a good value for a 3.0 or 3.3GHz overclock? also should loadline calibration be enabled?

thanks!

Re: getting a stable overclock with S3, EX58-UD4P

Now that you have ur specs in ur sig and ur BIOS template posted in this thread, go ahead and reiterate ur original question.

Wasn't it something like:

"...having trouble with resuming from sleep mode...."

Sry idk anything about i7... But ppl that do have some clues will gladly list possible things to try.

GL c ya 'round Joeblough.

Re: getting a stable overclock with S3, EX58-UD4P

thanks for helping me get right on this forum, BD3D.

yeah the original problem is that wake from S3 when overclocked is not reliable for me on the EX58-UD4P.

here's another data point: i lowered my bclk to 150Mhz and set the multiplier to 20x. the memory multiplier is at 8x, so unfortunately the memory is a bit underclocked. i left all the other settings unchanged, except that i turned on load line calibration.

i then set up an S3 torture test where i set the machine to sleep every 10 seconds, and set up another loop on a different machine to send an ethernet wake packet every 20 seconds. as of this moment it's properly slept and woken 40 times with no lockups.

so i guess this means that the "problem" is that bclk=166MHz is too high in the sense that something other than the CPU needs more voltage to run at that base frequency. any ideas?

np

I never have any probs until I reach between 3.7GHz and 3.8GHz. And then it becomes almost impossible fot my PC to resume from sleep mode. So I just shut down. 3.95GHz rocks! And its well worth giving up sleep mode.

Edit:

Thanks ProfJim!!! :D
