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.
