I bought a Tyan Tank server board (specifically: http://www.ebay.com/itm/like/272181383260?lpid=82&chn=ps&ul_noapp=true) and have not been able to get it working. I immediately get the FF code when I power on the psu, meaning that it is not posting correctly. I have tried resetting the cmos, reseating all the ram, and reseating other plugs. I have the 24pin, 8pin CPU, both CPU fans, VGA, and Sata cable. The only thing I can think of (besides a dead board or CPU(s)) is that there are 2 extra 4 pin connectors on the sides of the 24pin. They are differently colored than the rest of the essential connectors, and I have not been able to get it working if I plugged one into another PSU. Any ideas/help would be super appreciated, as I really don't want to return it! Thanks!!
