I have found more people reporting a problem with this mobo. According to others, the problem started when ASUS moved the factory from Taiwan to China, their quality went down. So you lucky ones may have the "good quality". Also I have not changed anythig, jumpers,... on that mobo prior to instalation. The first time when I burned the XP2400 I had no idea what was happening, on the second replacement I used temperature sensor to measure the CPU and within 90-100 seconds of powering the system up,it was at 65 deg. Celsia !!! That was when my T-bird 1.3 went by-by. I had both CPU tested and confirmed DEAD by Fry's return center. They were nice and tested both mobo and CPU even I did not purchased the item from them.
