CONFIGURING the SERVER
mirroring will go into effect on only two channels with two DIMMS per channel (you
cannot implement RAS on three channels). In this case, two DIMMS would go unused.
For more information regarding memory, see
CPUs and DIMMs on page 47
.
NOTE:
For memory mirroring, DIMM pairing across buses must be identical.
If you only have two DIMMs, they need to be the same PID because you have
one DIMM on each of two buses.
If you have four DIMMs in a 2-CPU system, for example, you can have two
4-GB and two 8-GB DIMMs. One 4-GB/8-GB DIMM pair would located on
Channel A of CPU 1, and one 4-GB/8-GB DIMM pair would be located on
Channel D of CPU 2.
If you have four DIMMs in a 1-CPU system, for example, you can have two
4-GB and two 8-GB DIMMs. One 4-GB/8-GB DIMM pair would located on
Channel A of CPU 1, and one 4-GB/8-GB DIMM pair would be located on
Channel B of CPU 1.
