Can't help you with a Winflash tool Msimax... I always use a bootable flash drive.

Has anyone managed to get 1066 ram to run on this board using the 1066 setting? The only way I can get it to run is to set it at 800 then OC the HT Ref clock to 266. This seems to work OK, but it limits the combinations I can get If I could actually use the 1066 setting...

I was just curious, seems odd that I can OC it up to 1066, but can't even boot into windows when it's set to 1066 in bios (It will post/but not boot)..
