Everything works fine overclocked to 4.0 GHz, including sleep.  Everything works fine overclocked to 4.4 GHz, except system won't come out of sleep mode.  I've set Vcore as high as 1.35 volts with Load-Line Calibration High.  Is there another setting in the BIOS that will effect recovery from sleep, or possibly a BIOS update?

You must disable Internal PLL Overvoltage. If it's in Auto its probably kicking in at x44 and will prevent S3 Sleep from working.

Thank you Sotiri.  I disabled internal PLL Overvoltage and now Sandy Monster is happily overclocked at 4.5 GHz, 1.300 volt and sleeping like a baby.

After struggling with this issue for over a week I'm glad to find someone with some intelligence and sanity.  The tech support guy at Asus told me it was a grounding problem and that I had to pull the MB and bench press it (or bench test it before he hung up on me).  It's amazing how many of these "gurus" on forums, etc. are advising people they have defective hardware because they don't understand what's going on.

I'm glad I don't have a Sabertooth whose sleep problem doesn't seem so easy to fix,
