Guidelines for mixture installation of DCPMMs and DRAM DIMMs
When you install DRAM DIMMs and DCPMMs on the server, follow these restrictions and guidelines:
•
Make sure the corresponding processors are present before powering on the server.
•
Make sure all DRAM DIMMs have the same product code and all DCPMMs have the same
product code.
•
As a best practice to increase memory bandwidth, install DRAM and DCPMM DIMMs in
different channels.
•
A channel supports a maximum of one DCPMM.
•
As a best practice, install DCPMMs symmetrically across the two memory processing units for a
processor.
•
To install both DRAM DIMM and DCPMM in a channel, install the DRAM DIMM in the white slot
and the DCPMM in the black slot. To install only one DIMM in a channel, install the DIMM in the
white slot if the DIMM is DCPMM.
