[XFastest] Puts different boards through VRM heat test, which will burn first?

Which has not relation to capacitance at all. And seeing this thread is about X79, we had OTP and OCP implemented properly on our boards from the get-go, so you cannot push them "out of spec" to the point of failure.

Not enough capacitance on either side of the fet could allow for out of spec operation dependent on the implementation method and BIOS settings. As was stated earlier though, the capacitance issue is more of a general issue and was not meant to be the "end all be all" statement nor to point to it being the largest of the issues or the cause of the fets entering cascade, only that due to the implementation methods used it is an issue.

You monitor each fet separately? I highly doubt that.

Do you even know how the monitoring functions of the drivers and fets work? If one fet enters a cascade scenario there is almost no method of reliably saving it from damage, let alone outright failure.
