I have an old Asus M3N-HD/HDMI motherboard in my rig, and I upgraded my Phenom 9950 BE, to a Phenom II 980 BE, and I have at least a 75% decrease in performance. I'm running Windows 7 SP1. I have the latest BIOS for my motherboard, which I reset to defualts. CPU Temps are at 30ºC. Cool and Quiet, and C1E are disabled. I enabled an auto 10% overclock in the BIOS, to 4.1 GHz, still dismal performance. I've tried both standard and auto settings in the jumper free configuration. Reseated my BIOS battery. CPU clock speed is right where it should be at defualt, 3.7GHz. I don't know what else to do. Is there something in the jumper free config that I need to take off auto, or standard? Or is it something else?
