Overclocking with Biostar 790gx - restart after resume from s3 with windows

[Stoneburner]

I can't find any guidance for this problem anywhere. A google search produced some similar problems with other boards, but the only solutions they had involved a new bios. There is no new bios available for this board yet (it's the 128m btw).

I have a Phenom II x3 710 with the 4th core unlocked.

I enabled s3 sleep in bios, ACPI version 3.0. When I'm not overclocked, it resumes just fine. When I overclock slightly even (FSB at 210 or so) i immediately get this problem. After I resume the computer, it'll show the windows screen normally for 2 or 3 seconds then proceed to restart.


Here's what I've tried so far.

1. Disabled "resume video on repost" - nothing
2. Lower HT and NB clocks - nothing
3. Loosened memory timings - i have some OCZ pc8500 that runs at 800mhz default on this board anyway. I still loosened the timings to 6 - 6- 6- 24. Nothing.
4. disabled cool n quiet
5. tried enabling and/or disabling all the settings under "power" in bios.

I don't think he overclock is unstable since even slight overclocks cause problems and since it ran stable at 3 ghz with OCCT 1 hour.

Have you tried overclocked w/o the 4th core enabled?

I have the same CPU/mobo combination as you (and unlocked), and sometimes it wakes from sleep, and sometimes not.

Will try this tonight.

did nothing. I tried disabling acc, increased the base frequency to 202, tried s3.... restart again

I guess this board just can't deal with s3 resume beyond stock

Biostar should really pay more attention to these warm boot, cold boot, S3.. etc. issues on its products.

Does C&Q have to be enabled to slip into S3 and then resume ??
