How to verify power provided to processors is clean

How to verify power provided to processors is clean

Once in a blue moon, I am seeing a blue screen of death on a shiny new
Dell R7610 with a single 1100 Watt Dell-provided power supply on a beefy
UPS. BCode is 101 (A clock interrupt was not received...), which some say
is caused by under-volting a CPU.
Naturally, I would have to contact Dell support, and their natural
reaction would be to replace a motherboard, a power supply, or CPU, or a
mixture of the above components.
In synthetic benchmarks, system memory and CPU, as well as graphics memory
and CPU perform admirably, staying up for hours and days.
My questions are:
Is power supply good enough for the application? Does it provide clean
enough power to VRMs on the motherboard?
Are VRMs good enough for dual Xeon E5-2665?
Does C-states logic work correctly?
Is there sufficient current provided to PCIe peripherals, such as disk
controllers?
P.S. Recently, I've gone through the ordeal with HP. They were nice and
professional about it, but root cause was not established, and the HP
machine still is less than 100%, giving me a blue screen of death once in
a couple of months.
