Raikiri said:I know, I have seen one do 468 with stock NB etc. but then with the RAM I had it was either mess about and spend more getting better or just go with this board as I knew the RAM would reach it's max before the board or CPU.
The point I'm trying to make (and it would seem failing

It took a LOT of work to get this AB9 up to 512 FSB, whereas the P5B ran to 525 with ease. The AB9 took a significant vMCH increase to get to 512 too, much more than is probably safe

The 1066 strap run on the AB9 hinders the max FSB overclock of the boards which is oh so important for the lower multi chips like the 6300 and 6400. Basically they overclock like the 975 boards do......
