64GB DDR4 ECC RDIMM for HP ProLiant

This 64GB DDR4 2933 ECC registered DIMM is built for HP ProLiant Gen10 servers including the DL160, DL180, DL380 Carrier Grade, DX170r and XL450. It operates at 1.2V with CL21 latency and a 2Rx4 rank configuration. The module replaces multiple original HP part numbers for a direct upgrade path.

Suited for ECC registered server slots.

This memory fits servers and workstations that require ECC registered DDR4 DIMMs. It will not work in standard desktop computers or systems that use unbuffered or load-reduced ECC modules. Mixing it with those types is not supported and can prevent boot or cause instability.

Single 64GB module at 2933 MT/s

One module delivers 64GB of capacity at the rated 2933 MT/s speed. The DIMM is backward compatible with 2133, 2400 and 2666 MT/s bus speeds, allowing it to run in older DDR4 server platforms. Total system capacity depends on the number of available DIMM slots and the server model's maximum memory limit.

Questions about this item

Which HP ProLiant server models must I already own for this 288-pin 64GB DDR4 2933 ECC RDIMM to work?

The module is validated for HP ProLiant DL160 Gen10, DL180 Gen10, DL380 Gen10 Carrier Grade, DX170r Gen10 and XL450 Gen10 servers.

Will this CL21 1.2V registered DIMM run alongside older 2133MHz or 2400MHz DDR4 modules I keep in the same server?

Yes, the module is backward compatible with 2133MHz, 2400MHz and 2666MHz DDR4 speeds, so it will downclock to match existing DIMMs.

How can I confirm the 2Rx4 ECC registered module is detected at 2933MHz after installation?

Check the server BIOS or iLO interface; it should show the new 64GB DIMM running at 2933MHz with ECC registered status.
