Hate to break it to you, but no. I turned every option regarding cpu or ram overclocking off and it still won't post stable. Doesn't matter, i am a cs phd, so i pretty much start the system in the morning and shut it down before i go to bed, this way i just have to start it before getting coffee :)
Have you tried setting the ram to lower than rated? For example, it could have been sold as 6000 but is only reaching 5600. There might also be a newer bios that fixes the common bug of memory retrain settings not being saved.
