Cause everytime when i flash to that version and load optimized defaults and after that customize settings in bios everything is fine, but whenever i turn off my pc and turn it on again (cold boot) it goes into a reboot loop 2 or 3 times and then it says checksum error and puts the original bios back (thank g(od)igabyte for dual bios).

Any ideas?
Yup, on cold boot it happens to me sometimes when running at 538 x 8 on my e8400 & ud3r with F7 (and F6a). It's annoying. Only away around it is to boot at a lower FSB (500) and OC within the OS. Tried various ref voltages, cpu term, vvt, etc without any luck. Changed memory (2x2GB Mushkin Redline) as well. S3 doesn't work either since F4 (i think). Bah, it's no big deal - once I OC in windows, it's still rock stable at 4.3 GHz.
