My AMD Athlon 64 X2 Brisbane CPU is running at 2.61GHZ instead of the stock rated 2.7GHZ. It is the BH-G2 revision. I just found out that the latest Dell c521 BIOS was 1.1.11, and I was running 1.1.10. I did a clean install, updated all drivers and upgraded the BIOS. Still it shows wrong clock speed. Should I exchange this for another? I understand that .1GHZ is not a huge difference, but I want to figure this out :lol:
