I flashed back to 714 bios which worked best for me, loosened my timings from 3 3 3 10 to 4 4 4 12, and I got an extra 60 mhz oc. Now sitting at 3.67Ghz up from 3.61ghz on a e6700. My 1M super pi times are .2 secs faster, and best of all... I can reboot from Windows!!!! I'm positive that this boards memory issues are also causing reboot problems.
