● 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.
● 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 4, 8, 16, or 32 DIMMs per system.

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 capacities are mixed, an F1/F2 warning is displayed as the
configuration is not supported.
● Intel Persistent Memory 200 series 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 operating modes (App Direct Mode, 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 and a DDR4 DIMM are populated on the same channel, always plug Intel Persistent
Memory 200 series on second slot (black slot).
● If the Intel Persistent Memory 200 series is configured in Memory Mode, the recommended DDR4 to Intel Persistent
Memory 200 series capacity ratio is 1:4 to 1:16 per iMC.
● Intel Persistent Memory 200 series cannot be mixed with other capacities of Intel Persistent Memory 200 series or with
NVDIMMs.
● Intel Persistent Memory 200 series of different capacities are not allowed.
● VMware ESXi boot takes longer time when higher capacity of Intel Persistent Memory 200 series are configured in App
Direct Mode (AP). This behavior is known as Address Range Scrub (ARS). This is an expected behavior as the background
ARS is going on the interleave sets and it must be completed prior to mounting the pMem datastore on ESXi.
● In App Direct Mode, sockets can be populated symmetrically or asymmetrically.
● In Memory Mode (MM), sockets can be populated symmetrically.
● Memory mode is not supported for the 6+1, 8+1 and 12+2 configurations irrespective of DDR to Intel Persistent Memory 200
series capacity ratio.
● In VMware ESXI environment, if BPS goal is changed between App Direct Mode and Memory Mode, it is recommended to
sanitize the Intel Persistent Memory 200 series before creating a new goal.
● Populate Intel Persistent Memory 200 series in DIMM slot 1, unless Intel Persistent Memory 200 series is the only DIMM in
that channel, and then populate in DIMM slot 0.
For more information about the supported Intel Persistent Memory 200 series (BPS) configurations, see the Dell Intel Persistent
Memory 200 series (BPS) User's Guide at https://www.dell.com/support/home/products/server_int/server_int_poweredge.
NOTE:
There are limited configurations available for dual socket servers with only one processor populated.
The following table describes the internal memory channels of the listed BPS configurations:
