I have been having bluescreen problems with my 680i board. It started when I upgraded to a q6600, 1066 memory, and a bios upgrade to P33. From reading this forum it sound like the bios upgrade may have been a mistake.
I may post a more detailed description of the problem and my system, but first wanted to try the "easy" fix of a bios downgrade. It sounds like P31 is more stable for q6600s. I only see the latest P33 bios on EVGAs site and on this forum. Where can I get P31?
