Hi there,
I have an Intel DX58SO motherboard that failed last year. One of the high side VRM MOSFETs failed shorted, and it killed my i7 980 CPU. This motherboard has a 6-phase VRM. The parts used on this motherboard's VRM are:
- 6 x High side MOSFET: NTMFS4841NH
- 6 x Low side MOSFET: NTMFS4834N
- 6 x Driver: ADP3121JCPZ
It was easy to figure out where the short was, because the bad MOSFET's gate was shorted to the drain/source too. Once I removed it, all the shorts were gone on the motherboard, and I confirmed on the removed MOSFET itself that the gate/drain/source...
