64GB DDR5 4800 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5 4800 CL40 registered DIMMs built for the HP Z4 G5 Workstation. ECC and registered buffering protect data integrity in professional workloads. The modules run at 1.1V and use major OEM Samsung, Micron or Hynix chips. They are designed for IT professionals who need reliable server-grade memory in a supported workstation platform.

288-pin registered DIMM form factor

Each module fits a standard 288-pin DDR5 RDIMM slot and operates at PC5-38400 speed with CL40 latency. The registered design reduces electrical load on the memory controller for stable operation under sustained loads. No heat spreader is included, so airflow in the chassis manages thermals. Builders must confirm the workstation has enough RDIMM slots and supports registered ECC memory before installation.

Two-module kit simplifies upgrade

The package delivers a matched pair of 32GB sticks, eliminating the need to source individual modules for dual-channel population. NEMIX RAM stress-tests every module under load and backs the kit with a lifetime replacement warranty. US-based IT support staff are available for compatibility questions. The kit targets buyers who want a validated, single-SKU upgrade rather than mixing loose DIMMs.

Questions about this item

What bandwidth ceiling does the DDR5 4800 (PC5-38400) interface impose on this kit?

The DDR5 4800 interface limits peak throughput to PC5-38400 rates, so this 64 GB kit cannot exceed that bandwidth ceiling regardless of workload.

What physical slot and module dimensions are required to install these 288-pin RDIMMs in the HP Z4 G5?

The HP Z4 G5 must provide standard 288-pin DDR5 RDIMM slots; each module is a single-rank 1Rx4 stick with no heat spreader, so clearance is minimal.

How are the two 32 GB modules seated, and which step do builders most often miss?

Insert each module at 1.1 V into the correct channel slots per the workstation manual, then press firmly until both side clips click — skipping the second clip check is the common error.
