I'm running a T-Bird AHYJA with Y stepping and week 24 on an Abit KT7A. I have the OZC Gladiator HSF and get idle temps around 39C. I have a 300W PSU and have no trouble running at 10*133(1333MHz). When I attempt to increase the multiplier (attempting 10.5*133) the system posts fine and boots to windows. During the initial seconds while it is still loading I am able to use my mouse and keyboard. When it is finished loading I get a hard lock and am forced to hit the reset button. I have tried increasing the voltage up to 1.85v with the same results. Am I not able to OC this processor or am I just doing something wrong? Any advice would be appreciated.
