1 TB DDR5 ECC RDIMM kit for HPE workstations

This 1 TB kit contains eight 128 GB registered DIMMs built for HPE Z8 G5 and Z8 Fury G5 platforms. ECC and register buffering protect data integrity in mission-critical workloads. The modules run at DDR5 4800 with a CL40 latency at 1.10 V. IT teams specifying high-capacity server memory for certified HPE systems will find the configuration validated for those platforms.

Sustained throughput with registered buffering

Registered signalling reduces electrical load on the memory controller, allowing all eight ranks per module to maintain stability under continuous multi-threaded demand. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute jobs. The 4800 MT/s data rate delivers consistent bandwidth for virtualization, rendering and database services without the throttling seen in unbuffered configurations under load.

Low-voltage operation without heat spreaders

Each DIMM operates at 1.10 V, limiting power draw and thermal output inside dense chassis. The absence of heat spreaders keeps the 288-pin modules compatible with tight slot spacing in the target workstations. Passive airflow from system fans is sufficient for normal operation, keeping acoustic levels low in rack or desk-side deployments.

Questions about this item

How much power does the 1.10V DDR5 4800 kit draw when the workstation runs continuously?

Each 128 GB module operates at 1.10 V, so the eight-module kit draws proportionally more power than smaller kits; actual wattage depends on the platform's memory controller and workload.

What motherboard slots and CPU memory-controller support are required for these 288-pin 4Rx4 ECC RDIMMs?

The modules need a DDR5 RDIMM-capable motherboard with 288-pin slots and a CPU that supports 4Rx4 registered ECC memory at 4800 MT/s.

Can the CL40 4Rx4 modules share channels with older DDR5 RDIMMs of different rank or latency?

Mixing 4Rx4 CL40 modules with different-rank or different-latency DDR5 RDIMMs is not supported; all slots in a channel should use identical modules for stability.
