I am swapping out a motherboard in a server for an Intel S5500HCVR model server m/b. Added both cpus and memory. I am getting a 1-5-4-4 beep code when powering up, which is a Power control fault (power good assertion timeout). I've swapped out the p/s for a new one and get the same thing. Also tested both PSUs with an Antec tester and they both appear good.
I can't test the 2nd cpu slot independently due to this m/b needing slot 1 filled first, but I have tested both CPUs and memory in the 1st slot.
Is there something on this m/b that I'm missing in terms of power requirements? The 8 pin CPU leads also tested good, FWIW.
