I currently have a S5000psl with two Xeon X5460 and 8 gb of ddr2 ram, I already checked the compatibility of the cpus with my motherboard and the compatibility of the ram with the motherboard as well. I've tried both with and without a graphics card, Ive tried taking out one stick of ram, running on 1 cpu, and still no video i do realize however that this board is said to work with my cpus with the newest bios update and i have no idea which bios version is on this board right now and have no idea how i am going to flash the bios without the video signal. I have also tried clearing the cmos, For my cpu power i am using a single 8 pin connector and the power supply is a 750w EVGA power supply so its more than enough power. The system starts with no video keeps running and then i see the solid amber led after about 35 seconds i would say, And im not getting any beeps with the ram out so i take it the onboard speaker is gone or the motherboard in total is gone.
The S5000PSL is end of interactive support (EOIS) reason why the only source of support we offer for the board is our website:
As an additional recommendation, when testing the system without memory you should receive 3 beep codes. If not the board is defective and needs to be replaced.
