HPE Compatible 64GB LRDIMM

This NEMIX RAM module delivers 64GB of DDR4 memory rated at 2933 MT/s with a CL21 latency. It operates at 1.2V and uses a 288-pin load-reduced form factor with 4Rx4 organisation. The module is built for HPE server and workstation platforms requiring ECC LRDIMM memory.

Suited for HPE server upgrades

IT teams expanding memory in compatible HPE systems will find this module matches the required specifications. Environments that need unbuffered DIMMs, non-ECC memory, or different rank configurations should select an alternative module type.

Handles large memory configurations

The 64GB capacity and load-reduced design allow dense population of memory slots for virtualization and database workloads. Systems limited to lower maximum module capacities or fewer populated channels will not be able to use the full density of this DIMM.

Questions about this item

Does this LRDIMM require a server motherboard with 288-pin DDR4 slots that support load-reduced memory?

Yes, the module is a 288-pin DDR4 LRDIMM and must be installed in a server board that explicitly supports load-reduced DIMMs at 1.2 V.

Can I mix this 4Rx4 64 GB module with existing 2Rx4 or 1Rx4 DDR4-2933 ECC RDIMMs in the same HPE server?

Mixing LRDIMMs with standard RDIMMs is not supported; all slots in a channel must use the same load-reduced technology for the system to boot.

How do I verify the module is running at DDR4-2933 CL21 with ECC active after installation?

Enter the BIOS or iLO interface and confirm the memory speed shows 2933 MT/s, CAS latency 21, and ECC status reports enabled for the new 64 GB DIMM.
