Hi,
Having some difficulties - any suggestions?
Bought a second hand Tyan s2895 HP XW9300 server board, and hooked it up to a working 610W EPS 12v PSU. With one opteron 242 in the first CPU socket, it boots. When 2 cpu's are installed, it won't power up (CPU's are both working fine). I had trouble finding which pins to short to get it powered up to begin with. Now, with one cpu, the computer powers as soon as the switch is flicked on the PSU. Nothing happens with 2cpu's, even when shorting the power pins.
Also, with one cpu installed, the monitor works with an old PCI card, but no video appears with a newly purchased Radeon 4830 PCI-E card (additional power adapter connected). It is new, so not yet know to be working, but the fan powers up without trouble.
Have tried clearing the CMOS and moving the RAM around.
Any suggestions or similar experiences? Can I suspect anything other than the mobo?
