I got the aforementioned board for free a few months ago in a lot of ewaste (previous owner said it was missing DIMMs) and recently got around to getting a 1650v2 to use in the board. However, upon powering it on, it tripped short protection on the PSU. I therefore decided to start probing it and found 2 shorts: 3.3V and the CPU connector. I revisited it again this morning only to find the 3.3V short gone. However, the EPS 12V short was still present, so I tried removing the CPU to rule it out, which cleared the short. The board will power on without the EPS connected but the CPU installed, though it won't power on without a CPU (X99 does the same thing).
Resistances measured:
EPS 12V-GND w/ CPU: ~1Ω
EPS 12V-GND w/o CPU: 1.5kΩ+, climbing
3.3V-GND w/ CPU: 5.4KkΩ
3.3-GND w/o CPU: 8.8kΩ
Is the board the likely culprit, or did I encounter my first ever bad LGA part?
