Thanks,

at present I am not even trying to get at higher speeds. or are you saying that since the 790i tends to have the default bios to DDR 3 at 1066mhz rather than factory default at 1333, I should try it at 1066?

I just checked the XFX force website, but they don't have the P04 bios yet. Ati has released a new catalyst driver y'day so will use that one as well.

But since the sun is now shining in this country called UK, yes I know hard to believe. Gonna take a stroll outside first
