the microprocessor kit.
Attention: Use of other VRMs might cause the server
to overheat.

Attention: To avoid damage and ensure proper server
operation when you install a new or an additional micropro-
cessor, use microprocessors that have the same cache size
and type, and the same clock speed. Microprocessor inter-
nal and external clock frequencies must be identical.

and the processor. This material when heated
and cooled causes the heatsink to adhere to the
processor. Some force may be required to
