Ok here is my situation. I have an Abit AN8 Ultra 2.0 Mobo that ran a 3700+ Sandy @2.7Ghz and I was upgrading to a Opteron 165 DC. Due to my watercooling I had to remove the Mobo to swap CPUs. Upon reinstallation and subsequent reboot, I get a BIOS beep of 1 long and 2 short beeps. Supposedly this means a video card recognition error. I have re-inserted and wiggled my X850XT multiple times as well tried my older X800Pro with no solution. I tried reducing the number of RAM Sticks in the system, but nothing is changing this! Any further ideas?
