[AMDrulZ]

i need help figuring out what went wron with my build i got a tyan s2912 dual socket f mobo that keeps giving me a post code of ff an a blamk screen when both a single cpu or both cpus are installed or with the video card plugged in or trying to use the on board video.. ant thoughts as to what it could be????

i think my psu has something to do with it it is a cheap orion 585w power supplies that i got a 2x 4 pin molex to 8 pin cpu adapter to try and make work... the board calls for an eps power supply any thoughts about it might be the psu..

Are you using ecc memory? You may also have to flash the bios to get it working properly.

yes i am infact using ecc memory it is kingston ddr2-800... the motherboard says it can take 400,533,667 but does not list 800. but i think it is the cpu that determines the memory capability and or speed in an amd system not the mobo.. when i have been trying to star the system i didn't have keyboard plugged in i don't no if i need a keyboard plugged in for it to post or not.. my monitor does not kick on either it says no signal but that i think is because it is not posting at all. but the board does power on and shows the error code ff..

well i think i found my problem the opteron 2000 series can only support up to ddr2 667 memory so i think that is why it won't post...

This board requires Registered ECC DIMMs, not just any ECC DIMMs. DDR2-800 doesn't matter.

the memory i got is registered ecc memory but it is pc2-6400 and the opteron 2000 series can only support up to pc2-5300.. so i guess that is why the board isn't posting..
