High-capacity DDR4 LRDIMM for dense server

This 64GB DDR4-2400 module uses a 288-pin Load Reduced form factor with 4Rx4 organisation and ECC. It operates at 1.20V with a CAS latency of 15 and is built with major-brand DRAM chips. The part matches HP specification 805358-S21 for direct compatibility.

Fits standard DDR4 LRDIMM slots in compatible HP

The Load Reduced design reduces electrical loading on the memory bus, allowing higher per-slot density without exceeding the platform's rank limit. Each module delivers 64GB of registered ECC capacity, freeing additional DIMM slots for further expansion or leaving headroom for future upgrades.

Sustained throughput at 2400 MT/s

Under continuous workloads such as virtualisation or in-memory databases, the CL15 timing and PC4-19200 bandwidth maintain stable data rates. ECC correction handles single-bit errors transparently, while the reduced voltage helps keep thermals manageable during prolonged utilisation.

Questions about this item

Does the CL15 latency become a bottleneck when this 64GB module runs at DDR4-2400 all day?

CL15 is the rated timing for the 2400 MT/s speed, so latency stays within spec under continuous load.

How much heat and power does a 1.2V 4Rx4 LRDIMM add to a fully populated server chassis?

Each module draws 1.2 V at its rated frequency; total thermals depend on how many slots you fill and your chassis airflow.

Which HP server part number must my system already support for this 805358-S21 equivalent to work?

The module is built to match HP part 805358-S21, so your server must accept that specification.
