BSOD 0x09c on 50 SuperMicro machines

Well this is super late, i imagine the issue is resolved by this point? Either way 0x9C usually means a MCE hardware fault, Our GPU systems ran linux as a host os which reports these errors a bit more verbose than windows.

Anyways, these were randomly popping up for us on similar hardware made by HP a while back, It ended up being insufficient power delivery to the GPU. Specifically the 75W that's supposed to be supplied by the PCIe port itself.

We confirmed it with a multimeter on a PCIe breakout board. Voltage dropped when both GPU and 10Gbe network cards were being hit hard at the same time. While the motherboard was capable of delivering 75W to the x16 slot, the power delivery section struggled a bit when the other cards were all consuming power.

The riser may be suspect here and dropping voltage on high current loads.
