    Overclocked i7 920 with DX58SO and Win7 Sleep - What a headache!

      This has to be the most annoying PC problem I've ever had.

      And that's saying something.

      I have an i7 920 and a DX58SO board that's overclocked it to a nice stable 3.8ghz. Stress tested fine, temps were perfect.

      Enter Windows 7 Sleep.

      I had made sure my BIOS setting had the S3 enabled (had NO problems coming out of sleep with the stock settings) and left the PC for a while. I then came back expecting the PC to 'wake up'.

      The fans turned on, the lights blinked, but the monitor remained black.


      I reset the PC, thinking that stupid thing froze (in hindsight, I should have waited longer). So now I'm waiting for the motherboard splash screen to show up (DX85SO) and nothing happens.

      Stupid thing won't even post. Just a black screen. I try resetting again, and the PC turns on for about 10 seconds and then turns off. When I was overclocking, the board would at least let me know that it wouldn't post and would allow me back into the BIOS. Not this time.

      I try this again and again and I finally make it to the BIOS setup, but it freezes while IN the BIOS. After clearing the CMOS and moving the motherboard jumpers (which didn't work until the 5'th time), I make my way into the BIOS and reset it back to stock.

      Now it works fine.

      Wakes from sleep, and starts properly.

      My question is, what's up with overclocking and sleep mode? My only theory is that maybe I wasn't giving it enough power to wake up out of sleep mode (1.2 volts on the cpu). What's even more strange is that when I forced the PC to sleep (start button -> sleep), it woke up fine. It wasn't until it slept 'naturally' that it froze.


      Any ideas?
