Hello, this is my first post. I've been an avid pc guy for about 7 years. I have an A7N8X DX Ultra 400 rev 2.xx and a barton 2500+ currently running at 2200(209x10.5). My Q is, whenever i use multi's higher than 10.5(11 and above) with 200fsb, i get no boot and whenever i put my cpu voltage on anything but AUTO i get MAJOR instability. Could my CPU be locked? Or is it maybe the MOBO? PC Probe says volts are 11.904, 4.919, 3.28 and 1.68. Cooling on air right now(RBX waterblock, aheim 1250 and Maxxxpert rad waiting to be finished). NOTE: HAVING IT ON AIR OR WATER DOESNT EFFECT THE PROBLEM.
