SuperMicro H8DG6 Power LED

[Brainbug]

Looking for a second opinion.

My dual socket H8DG6 server suddenly stopped, and will not power back on.
- The IPMI status LED does blink, but the DP3 (Power) LED does not power on.
- When attempting to power on the system, the PSU fan spins briefly then shuts off.
- IPMI status does not detect any voltage. No errors/warnings in the IPMI event viewer.

I have performed the following troubleshooting steps:
1. Tested power supply, working on different system.
2. Connected power supply to everything, *except ATX and EPS*, and jumpered the ATX. All peripherals power on successfully.
3. Removed the second CPU, and all but the "Blue" RAM sticks for CPU 1. No change.
4. Replaced CMOS battery. No Change.

I believe the mainboard has kicked the bucket, but looking for advice on anything I may have overlooked before I buy a replacement H8DGI/H8DG6.

Try a known good cpu in socket 1 with 1 stick of ram, check the power sockets for any signs of scorching, has something got in between the mobo and case causing a short?. Troubleshooting a 2cpu board is a PITA and you have pretty much covered all the bases

Bought a new mainboard which came with 6272s in order to do some trouble shooting.

Turns out one of the two CPUs and the Mainboard are dead, not sure if the mainboard killed the CPU or vice versa. Typically I can find the cause of the problem (MOSFET, Capacitor etc...) but haven't been able to locate the issue on this one.

If anyone has a ZS222445TGG44 or a pair of 16xCore ZS CPUs, my single proc is now lonely.

Posting some pics, in case anyone wants a look. (Discolouration on the CPU1 MOSFETs is residue from the stock heatsink)

What kind of G34 chips are you looking for?

Single Spicy 6274 or a Pair of 16 Core 62xx/63xx. If you know a good dealer, I'd be much obliged.

I'd post in BST, but apparently I spend too much time on IRC and not enough posting in the forums.
