The P4QH6 runs perfectly with 1 or 2 Intel Xeon MP 1.4GHz processors, but when I populate 4 CPUs, the system won't boot up and VID LED is showing red.
Please make sure u don't use the DP Xeon CPU on this Quad platform, check your motherboard revision and BIOS revision and contact with our tech support if you still have issue with 4 MP Xeon.
