HPE 64GB 2Rx4 DDR5-6400 RDIMM SmartMemory Kit

P64986-B21 is a 64 GB, 2Rx4 DDR5-6400 registered kit with ECC and a CAS latency of 52. HPE lists the ProLiant DL345 Gen11, DL365 Gen11 and DL385 Gen11 as compatible systems.

Confirm your server configuration before ordering. A 64 GB module at 6400 MT/s is the entry point for high-speed DDR5 in that family.

Because the CAS latency is a bit higher at this speed, the module is intended for platforms rated for 6400 MT/s. Mixing speeds in one server makes the memory run at the lowest rating. It is listed for three Gen11 models, the DL345, DL365 and DL385, so a different ProLiant generation is outside the compatibility list.

Condition options are new and refurbished, both with a 1 year or 3 years warranty.
