Had this board for about a week and have got to say its been a major dissapointment. Can't get above 450FSB no matter what I try and thats with a QX9650 and an E8400 that will do 520FSB on my P35 board. A user on overclockers forums has got it to 571FSB with an E8500 but I couldn't get anywhere near that because of contant blue screens and cold boot problems.
I suspect it is a bios issue with memory as 2 instances of high FSB's have been with dedicated 1066 memory. I have ballistix 667 memory that overclocks past 1100mhz but wont go above 900 on this. I have seen Asus boards have the same problems with memory. I have never seen so many bios options either!
