I'm using SPI400W FSP400-60GN. See the system config in my sig.
My system is fully stable at 2.5GHz/1.85V. At 2.6GHz/1.95V it's stable until I loop Prime95. After running a hour or so my system will freeze or reboot. It's odd that Prime95 never got the chance to crash or report an error. The cpu temperature never above 45C. I suspect that either my PSU isn't up to the task or the voltage regulators can't handle that amount of power. Speedfan reported around 4.6-4.7V for 5V rail when under load. What's your opinion?
