I have a Tyan Tiger MP mobo. The system monitor that reads temps, show "VRM2". What exactly is this? Why does it get so friggin hot? When I run UD distributed computing, it gets to nearly 70 degrees Celcius!

Voltage Retention Module for the second processor.

It's basically the VCore regulator.

A VRM is a voltage regulator. You need VRM's for the cpu core voltage as well as the memory. Slots usually get power direct from the power supply while the CPU and memory want extra clean stuff (not to mention variable voltage as indicated by the Voltage ID pins) and thus use a VRM. 70C seems quite hot for a VRM.
