Installing and Removing a VRM (Voltage
Regulator Module)
Each Pentium II Xeon processor requires two VRMs (Voltage
Regulator Modules), one for the processor and another one for the L2

two Pentium II Xeon processor, you need three VRMs: two VRMs for
each processor and one VRM for both of the L2 cache to share.
Refer to section 3.1.2 for the location of the VRM sockets. The
following table shows the VRM socket allocation:
