GA-X58A-UD3R (rev. 2) - Sleep Mode Problems

[icer22x]

SPECS:
MOBO: *listed in title*
CPU: i7 950 OC'ed to 3.8GHz *see end of post for overclock details in case it helps*
PSU: Corsair HX Series 750W
GPU: GeForce 260
RAM: Corsair 1333MHz (6GB)
OS: Windows 7 x64

PROBLEM:
I usually put my computer to sleep when I go to work/bed. I wake it up by pressing any key on the keyboard. Sometimes I will try to wake it and it won't come on - I will have to press the power button on my computer. It's like it shuts off by itself. When it boots I always get a black screen on the first boot with a blinking gray cursor. The only way to get a clean boot is to press the restart button on my case.

What in the world could be causing this? And why is it intermittent? If it helps, I have ACPI Suspend Type set to "S3(STR)" in the BIOS. Upon reading this, it suspends to RAM when in sleep mode..

Here is my overclock information if it helps. Thanks guys.

Hi

The first thing to understand is that S3 sleep mode won't work properly unless the system is 100% stable so I expect that is where your problem lies. You will need to make sure your system is perfect at stock speeds and then try S3 sleep mode.

I never have any issues with this set-up while it's running. Even during graphic intensive games that run for hours. I've never had a restart or a BSOD. After reading about the Windows 7 Sleep function, I've figured out it's not 100% reliable and that it works better on laptops.

I've always had problems with Windows and the Sleep function, even back with XP. I've done hours worth of runs with memtest and IntelBurnTest - never having a problem whatsoever.

Do you see anything wrong with my BIOS overclock settings? They seem pretty stable to me, but I am new to OC'ing with the i7. I am not 100% certain that my voltages are correct and there could be some obscure setting that I need to enable/disable.

But thanks for the help.

In general your settings look fine  and if the system is working without problems then they must be. I would agree about the sleep modes being a PITA and cause more problems than enough but some people can't seem to live without them, so hey. Personally I disable most of them.

Okay. Well, thanks for the help. I'm paranoid about overclocking without much experience with the i7's... then I remembered how Sleep in XP would sometimes not even initiate... I'd have to shut the system down (which is what I am doing now with my old build instead of putting it to Sleep - shoot, it starts up fast enough anyway).

[Dark Mantis]

Well that is my way of thinking too. Also if you shut down and restart at least it doesn't give the crap a chance to build up.

True - gotta be something weird happening if it's saving it all to RAM.

Anyway, love your avatar. MGS is my favorite game series of all time. (Snake Eater was my favorite although 4 was incredible as well).
