Power Problem? MA790X-UD4P

[copernicus]

Just picked up this mobo, with a PII X2 550 BE, and a HD 5850, got it installed and keep getting 1 short beep over and over about 3-4 seconds apart, according to the manual that should mean a power problem, this is the power supply, same one in my sig.

was working just fine with parts in my sig just 2 hours before, I' ve got both the 4 pin cpu connected and the 20+4 main, also both pcie connected. and don't have a spare to try
hoping to not rma this board or have to get a new power supply.
any help or ideas are most appreciated

try the amd cpu forums, you will get a lot more help there.

Have you tried w/ just one stick of RAM installed to the first DIMM slot closest to the CPU?

thnx for the tip sorry for delay back was an extremely busy week

the mobo does not like my ballistix from my sig, would not work in any slot.
remembered i had some mushkin ddr2 800 in a box, broke it out and tried it and it booted first try, updated bios and tried the ballistix again and still a no go (i think it is seriously undervolting it my 790fx board did it too would boot was not stable till i raised the voltage) so i'm stuck with the ddr2 800 for now.

one bright spot, i got all four cores unlocked and so far so good @3114mhz @1.425v still gotta run p95 for a lengthy test, passed 30 min so far and passed 20 min on occt

one bad thing, i can not get any temp readings now, coretemp read fine when it is dua,l but as quad it only shows 0

Put in mushkin raise the voltages then try balistix again , set loose settings to make sure the sticks boot tweak afterward
