Table 20. Memory population rules (continued)
Processor
and processor 2 population
should match)
● Populate all the sockets with white release tabs first, followed by the black release tabs.
● Memory modules of different capacities can be mixed provided other memory population rules are followed.
● Mixing of more than two memory module capacities in a system is not supported.
● Unbalanced or odd memory configuration results in a performance loss and system may not identify the memory modules
being installed, so always populate memory channels identically with equal DIMMs for best performance.
● Supported RDIMM / LRDIMM configurations are 1, 2, 4, 6, 8, 12, or 16 DIMMs per processor.
Intel Persistent Memory 200 series (BPS) installation guidelines
The following are the recommended guidelines for installing Intel Persistent Memory 200 series (BPS) memory modules:
● Each system supports maximum of one Intel Persistent Memory 200 series (BPS) memory module per channel.
NOTE:
If two different Intel Persistent Memory 200 series (BPS) capacities are mixed, an F1/F2 warning is displayed as
the configuration is not supported.
● Intel Persistent Memory 200 series (BPS) can be mixed with RDIMM, LRDIMM, and 3DS LRDIMM.
● Mixing of DDR4 DIMM types (RDIMM, LRDIMM, and 3DS LRDIMM), within channels, for Integrated Memory Controller
(iMC), or across sockets are not supported.
● Mixing of Intel Persistent Memory 200 series (BPS) operating modes (App Direct, Memory Mode) is not supported.
● If only one DIMM is populated on a channel, then the DIMM should always be populated in the first slot in that channel
(white slot).
● If a Intel Persistent Memory 200 series (BPS) and a DDR4 DIMM are populated on the same channel, always plug Intel
Persistent Memory 200 series (BPS) on second slot (black slot).
● If the Intel Persistent Memory 200 series (BPS) is configured in Memory Mode, the recommended DDR4 to Intel Persistent
Memory 200 series (BPS) capacity ratio is 1:4 to 1:16 per iMC.
● Intel Persistent Memory 200 series (BPS)' cannot be mixed with other Intel Persistent Memory 200 series (BPS) capacities
or NVDIMMs.
● Mixing different capacities of RDIMMs and LRDIMMs are not allowed when Intel Persistent Memory 200 series (BPS) is
installed.
● Intel Persistent Memory 200 series (BPS) of different capacities are not allowed.
● VMware ESXi boot takes longer time when higher capacity of Intel Intel Persistent Memory 200 series (BPS) are configured
in AppDirect mode. This is expected as background ARS is going on the interleave sets and needs to be completed prior the
pMem datastore is mounted on ESXi.
● App Direct (AD) can be populated symmetrically or asymmetrically across sockets.
● In Memory mode (MM), symmetry across sockets is required.
● Memory mode is not supported for the 6+1, 8+1 and 12+2 configurations irrespective of DDR to Intel Persistent Memory 200
series (BPS) capacity ratio.
● In VMware ESXI environment, if BPS goal is changed between App Direct and Memory mode, it is recommended to sanitize
the DIMMs before creating a new goal.
● Populate Intel Persistent Memory 200 series (BPS) in DIMM slot 1, unless Intel Persistent Memory 200 series (BPS) is the
only DIMM in that channel and then populate in DIMM slot 0.
