Default Gigabyte mobo keeps resetting OC settings on cold boot!!!

After getting a stable OC, whenever I turn off the comp and try to turn it back on seconds later, it would repeatedly turn off and back on, indefinitely. It would not even get to the POST screen. Pressing the power button won't turn the comp off at this stage.

To fix this I have had to turn off the power at the back to force shutdown, then wait a while before turning it on. Then I would find that all my OC settings are reverted to default settings, which I would then have to re-enter.

I'm running a gigabyte P35/DS3 on an e2220
vcore 1.4v, MCH +0.1v, Apacer 4gb ddr800 at 938, ram timings auto.

Does this happen to anyone else? How can I fix this?

edit: I noticed this is a common issue with Gigabyte mobos and was wondering if this has been solved yet? After searching, I couldnt find a clear solution to this.

Sounds like your OC is not stable. Go back to stock and work your way up...

I had the same issue with my gigabyte p965 board, using the F11 bios. I updated to the F13 bios and had to shave 50mhz off my overclock then it would keep my settings and reboot ok.

No matter what I did with F11 rebooting always resulted in resetting to default clocks even if my PC had been on and stable for 30+ days.

My Gigabye P35 DS3P doesnt seem to have that issue. Using the latest bios it retains my overclock perfectly every reboot.

i had the same issue with my p35 ds3.

OC was perfectly stable, but on cold boot it would revert to failsafe, warm reset it would keep the overclock.

It for some reason just stopped happening to me, out of the blue.

i've had 2 cpus & 2 sets of ram thru this mobo with same issue, its got me stumped.

oh, it did this on f4 and f12 bioses for me too.

Agreed.

Funny thing about overclocks, or so ive learned, it'll be stable one day and not the next.

If you're not keen on the advice given then not sure what else we can tell you?

Give the MCH & FSB more juice and increase RAM volts - if the RAM is up to it. I found these items to have more of an impact on POST-ability than vCore alone.

DS3 is not exactly the overclocker's choice, so you might have to be more persistent/patient than you would with a high end board. 'Tis half the fun innit?

Ok it seems any settings worth keeping will be lost on a cold boot on this mobo, therefore I've decided my current rig is effectively unOCable (lest I do what some other members here do - leave the comp on 24/7 and maybe put it on standby mode)

Thanks for the helpful suggestions tho

My P35-DS3R had a Similar problem but not with a cold boot.

If I restarted it from windows it would power up for a second then shutdown and keep doing that cycle until it reset my clocks.

I figured out it was a ram issue. I have since upgraded to crucial ballistix and haven't had a prob.

But cold boot ALWAYS worked for me, I found it was easier to shutdown and then power it up than to restart it and have it do its annoying cycle.

Would you mind posting the rest of your specs?

What PSU are you using?

ive had similar problems (still am) like echelon6.

the overclock may work the day you set it, then the next day it wont boot with those settings. i read somewhere on the net saying the DS3P wont overclock with my 7900GT (or 7 series cards).

i tried my old X800 after reseting everything to stock including the HSF back to the stock intel one and booted with a small overclock and it seems to work fine. so i believe the 7900GT is causing my oc problems or mainly because the mobo is not compatible with the card

Just thought I'd chime in on an oldish thread after a search couldn't find anything better.

Recently upgraded to a EP35-DS3P with a E8400 and I have the same problem.

Computer is entirely stable after a reset with OC settings, resets bios with a few beeps on a cold boot. Have to reset everything again. F3n BIOS.

Even a mild overclock (safe timings - FSB increase only) can set it off and get the same result as a larger overclock with 1.4V.

I have been experiencing this since I started overclocking. I think I found a sort of answer last week when I was testing some kicgston 667 ram at above 800.

I have noticed that when rebooting after a memtest86 boot cd, that the bios would reset. So I decided to use this to tell me when the ram would be stable.

I would boot memtest. run for about 1 minute - just enough to pass test #2 where it writes all the ram, and then reboot. If the bios didnt reset once after doing that 3 times then that configuration was stable.

I was very careful to ensure I didnt save the bios when the ram wasnt stable.

I tested heaps of settings, with heaps of fsb values, but couldnt get anything over 800fsb to reboot from memtest reliably. So I accepted that 800 fsb was as high as I could go with this ram, and set out to find timing values that worked.

Having done that I booted windows - immediate bsod!, and again, and again.

I was shattered, I had seemingly wasted about 5 hours of testing..

But I knew from the memtest reboot tests that 800fsb would boot hot or cold reliably. So I figured I now I just need to stop the bsods. To do that I increased the cas etc. timings. I had originally found 4-4-4-12 to be stable when rebooting from memtest, so eventually, I found 6-6-6-18 to stop the bsods.

I conclude from this that in my case: when bios resets itsself that the ram is running at too high a FSB - reduce FSB until bios doesnt reset.

And, when bsods occur the ram is running at too tight timings - increase timings until bsods dont occur.

After a reset or two (HDD activity indicates that Windows is loading - just the screen stays blank), I can be Orthos stable for several hours. Or sometimes it resets back, can never tell.

It certainly is an odd issue, no rhyme or reason. Just doesn't like an overclock...

Researched the HELL out of this problem, with the love of google and various forums, I eventually came to realise it was a bizarre setting in the BIOS that would never strike any interest in relation to this problem, and is an exclusive issue to GIGABYTE boards only.

Try setting the Legacy USB Storage to 'disabled' ... give your FSB a big increase and I dare say you'll be in for a real treat.

Thank me later though; try it first

I'm thanking you now. Usually I disable all that crap, pretty much everything but I missed that one and yes, that is the one to blame.

Just tried it then and I'm now typing from Windows at 444x9 (3996) at 1.3v.

Cheers. You wouldn't happen to know why my video card is only running at x1 when it's in the top x16 slot, would you?
