64 GB DDR5 ECC RDIMM for HP Z4 G5

This 64 GB registered DDR5 module targets professionals expanding an HP Z4 G5 workstation. It delivers error-correcting memory for workloads that require data integrity and system stability under continuous operation. The single-stick configuration simplifies capacity scaling within supported slots.

Sustained load behaviour with ECC registered design

The registered buffer and ECC circuitry maintain signal integrity and correct single-bit errors during prolonged compute tasks. Operating at 4800 MT/s with CL40 latency and 1.10 V, the module is validated for continuous server-class workloads without the signal degradation seen in unbuffered alternatives. Major OEM DRAM from Samsung, Micron or Hynix underpins consistent throughput.

Pre-order compatibility checks for this module

Verify that the HP Z4 G5 motherboard supports 2Rx4 registered DDR5 DIMMs and that the BIOS revision recognises 64 GB density per slot. Confirm available 288-pin RDIMM slots and that the memory population rules allow a single module installation. Cross-reference the HP part number MR38400-924K1 with the system service manual before ordering.

Questions about this item

How much power does the 1.1 V DDR5 module draw when the workstation runs continuously?

The module operates at 1.1 V, the standard voltage for DDR5, so power draw stays low even during all-day workloads.

Does the HP Z4 G5 need any specific BIOS setting or firmware revision before this ECC RDIMM will be recognised?

The 288-pin DDR5 RDIMM is built to the HP Z4 G5 specification; install it in an available slot and the system will detect it automatically.

Can I keep my existing DDR5 4800 CL40 ECC RDIMMs and add this 64 GB stick without timing conflicts?

Yes — matching speed, latency, voltage and registered ECC design means the new module will run in step with identical modules already installed.
