I tried your bios. But I noticed something strange under Vista Ultimate x64. My machine was prime95 stable but not "x264 stable". It means it could run prime95 test for 10 hours, but not x264 video encoding for 15 minutes. Besides this encoding was to slow for 4 cores processor, almost the same speed as my old E6600. Furthermore, Everest CPU tests results were to low, on C2 Duo level, too. During the tests CPU usage was 100% only for two cores. For other two where only around 50%.

I have dual boot machine and all above I noticed under Vista Ultimate 64. Under Windows XP Pro SP2 x32 video encoding and Everest CPU test was normal for Quad core processor. I flash bios to 2301 and now x264 video encoding speed and Everest CPU tests results under x64 Vista are on the XP 32 level. Although I can't oc my quad any better than with your bios, now is at least "x264" stable and use all four cores for encoding and Everest benching.

It seems Asus made new bios for GO stepping processors with a reason.
