Just installed a used X4 970 BE in my Asus M2N-E board. The multiplier won't go above 4 even when I go into the bios and manually change it. I have also tried turning off CnQ. BIOS is updated to the Beta 5001. I have done a lot of research and can't find an answer to this issue.
I realize the ASUS website doesn't say this cpu is supported but I have looked around and CPU Upgrades, http://www.cpu-upgrade.com/mb-ASUS/M2N-E.html
has it listed as supported. Also read a few posts about it working fine. I'm currently running 32 bit XP but will be upgrading to Win 8 64 bit.
