It sucks.
I flashed to Bios 12.02 and bootet up 400x9 - or so the board would tell me at post. In Windows, CPU-Z, Everest and so on tell me that I'm actually running stock FSB - SuperPi confirms this. I also tried 12.05 with the same result - no matter what multiplier and fsb I set in Bios, it always uses the default FSB. OMG... should've stayed with 11.02.
I'm going to bed now, like I said its been a long day.
