HPE Server Memory Upgrade

This 128GB DDR5 RDIMM is built for HPE server and workstation platforms that require registered ECC memory. It targets IT professionals who need to expand capacity in compatible systems using a single high-density module. The part is validated for the HPE P43334-K21 specification and ships new from NEMIX RAM.

Thermals Noise and Power

Operating at 1.10V, the module draws low power for its density and runs without a heat spreader. Registered buffering and ECC functionality add negligible latency overhead while maintaining signal integrity under sustained server workloads. No active cooling is required beyond standard chassis airflow.

Deciding Specification 4Rx4 Rank Configuration

The 4Rx4 organisation determines whether the memory controller can address this module at the rated 4800MT/s speed. Systems limited to dual-rank or single-rank DIMMs will not support the full capacity or may fall back to a lower data rate. Verify the platform rank limit before purchase.

Questions sur cet article

How do I install this 288-pin DDR5 RDIMM in my HPE server and what step is often missed?

Power off the server, open the chassis, align the notch on the 288-pin DDR5 RDIMM with the slot key, press firmly until both ejector clips lock, then verify in BIOS that the 128GB module registers at 4800 MT/s with ECC active.

What maintenance or replacement will this 4Rx4 registered ECC module need over its service life?

The module has no heat spreader and no moving parts, so no scheduled maintenance is required; if a correctable ECC error count rises above the platform threshold, replace the DIMM under the lifetime replacement warranty.

What limit appears first when this CL40 1.1V DIMM runs sustained workloads?

The CAS latency of 40 cycles at 4800 MT/s sets the timing floor, so sustained throughput is bounded by the 38400 MB/s PC5-38400 rating before thermal or voltage limits are reached.
