The mainboard supports
Single
AMD
®
Opteron UP or
Dual
AMD
®
Opteron DP
™
processor(s). The mainboard uses two CPU sockets called Socket 940 for easy CPU
installation. You can install SINGLE or DUAL CPUs on the mainboard to meet your own
needs. Keep the following points in mind before installing CPU(s):
1. If
SINGLE
CPU is intended, always install the CPU on the
U1
socket.
2. To install
DUAL
CPUs on the board, you must use
the same type/
stepping of AM D Opteron DP
™
CPUs running at the same
fr equency
.
As processor technology pushes to faster speeds and higher performance,
thermal management becomes increasingly crucial when building computer systems.
Maintaining the proper thermal environment is key to reliable operation. As such, the
processor must be maintained in the specified thermal requirements.
You need to add thermal grease between the CPU and heatsink to improve heat
dissipation. Then, make sure that the CPU and heatsink are securely fastened and in
good contact with each other. These are needed to prevent damaging the processor
and ensuring reliable operation. If you want to get more information on the proper
cooling, you can visit AMD
’
s website for reference.
