GA-P31-DS3L - cold boot issue

[gammax]

Hey

I've got gigabyte GA-P31-DS3L with Core 2 Duo E6750 CPU and 2x2GB OCZ Titanium RAMs.
I made OC up to 3.2Ghz (its enough for me) and all were fine,
I compiled many programs without any freezees etc. - MB was just stable, rly no errors.

And later, I left my PC for 24hours.
When i tried to run it next day I've got reboot (first one reboot, later second reboot and finally bios default settings)

Could you tellme why?
Setting were rly stable, I don't understand this.

I checked the net and I found couple similar threads, about this MOBOs.
Is this a MB issue or smth?

I've tried to change PSU, increase the voltages, remove one RAM from slot, change the BIOS ver - nothing, the same effect.
All is working OK with 3.2Ghz and later I get bios defaults

Sorry for my english.

Best regards,
Tom.

Hi Tom,

I bet you locked the PCI-E frequency at 100...

Have a look at this thread.

1. Were you Prime95 stable?

2. Read:

That guide will apply to you.

My guess is you:
1. RAM was above the 1:1.
2. Too little voltage for RAM/CPU
3. Unlocked PCIe

hello,

Thanks for the replies guys.
I checked this guide, but nothing.
Still the same effect, even if my PC will boot with 3Ghz+ it's working rock stable, but after some hours if I trying to run it again I'm getting two restarts and default OC settings.

I tried my c2d on ASUS P5Q Turbo (or something like that) and was OK with 3.6Ghz.

Some shot from my BIOS config (multipler is x8 max)





[edit]
I can switch the mobo to ASUS P5K without any extra money, do you think that will be a good choice?

Definitely yes. P31D3SL is not good for overclocking. P5K would be waaay better choice.

P.S. You can push the P31 above 3.2GHz if you set the PCIE freq to AUTO.
