64GB DDR4-2400 LRDIMM for servers

This 64GB module targets administrators who need to maximise memory capacity in HP-compatible servers. It delivers 64GB per 288-pin slot using Load Reduced technology so dense configurations stay stable. The part matches HP 805358-B21 specifications and uses major-brand DRAM from Samsung, SK Hynix or Micron.

CL15 at 1.2V with ECC protection

Rated DDR4-2400 (PC4-19200) with CAS latency 15, the module operates at 1.2V while providing full ECC error correction. Load Reduced buffering reduces electrical load on the memory controller, helping thermal headroom in fully populated chassis. Major-brand components ensure consistent power draw across all ranks.

4Rx4 organisation frees slot density

The 4Rx4 rank layout packs 64GB into a single LRDIMM, letting you reach high totals without filling every slot. Compatibility is guaranteed for systems that accept this DDR4-2400 LRDIMM specification, preserving existing service contracts. Buyers who need registered RDIMMs or non-ECC modules should choose a different product.

Questions about this item

How is the 288-pin DDR4 LRDIMM installed and what step is often missed?

Align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify the module registers at 2400 MHz in BIOS; the step often missed is enabling the correct voltage profile so the stick runs at its rated 1.20 V.

What maintenance or replacement will the 64 GB 4Rx4 module need later?

No scheduled maintenance is required; if a memory test eventually reports correctable errors on the major-brand DRAM chips, replace the individual LRDIMM rather than the full set.

What limit appears first when the LRDIMM runs sustained workloads at 2400 MHz?

The thermal ceiling of the 4Rx4 organisation is reached before bandwidth saturates, so sustained throughput tops out at the rated PC4-19200 line rate once the module hits its operating temperature envelope.
