P67A-UD5-B3 Sleep issue
Just got the board, I like it so far but am limited by an S3 sleep issue for my 24/7 OC.
So far, everything points to "CPU PLL Overvoltage" setting in BIOS not sticking on S3 resume.
For example, I have tested "stable" (1 hour Prime Blend test):
4.4Ghz: 44x Multi, PLL OverV disabled/Auto, other settings identical to x45 multi
4.5Ghz: 45x Multi, PLL OverV enabled, other settings identical to x44 multi
Temps are fine, and load voltage around 1.32v @4.5.
Stock = Sleep OK
44x with Pll OverV OFF = Sleep OK
44x with Pll OverV on = Sleep Problem
45x with Pll OverV on = Sleep Problem
So it goes to sleep fine, but on resume fans spin & there is no vga.
- 10 seconds later it reboots
- after reboot every 2 seconds it goes into an endless reboot cycle.
- I Power off PSU, then reset Bios.
- Enter Bios to set any of my OC's or Optimized defaults (even OC with OverV=on does not matter)
- Reboot, and system just resumes from sleep normally in a couple of seconds as if nothing happened (10 minutes later...)
Like I said, I think this is related to the "CPU PLL Overvoltage" setting in the BIOS not sticking on resume. The board will NOT boot above 44X Multi if this setting is not enabled, but S3 sleep only works if I disable it .
Anyone here experience similar problems? I tried tweaking voltages to be able to boot with the 45x Multi OverV= off, but no luck. Any solutions until they release a new BIOS?
EDIT: Tested with BIOS F2 and F3C
