128GB DDR4 ECC LRDIMM for servers

This 128GB DDR4 3200 module is built for servers, workstations and NAS systems that require ECC load-reduced memory. It operates at PC4-25600 with CL22 latency and 1.2V. The 4Rx4 organisation and 288-pin form factor suit high-density configurations where registered or unbuffered DIMMs are not supported. It replaces HP part numbers P07652-H21 and P25206-B21.

JEDEC-compliant load-reduced design

The module follows JEDEC and RoHS standards and carries no heat spreader, relying on chassis airflow. Load-reduced architecture reduces electrical load on the memory bus, allowing higher capacities per channel than standard registered DIMMs. The 288-pin edge connector fits DDR4 server slots only; it cannot be used in desktop boards that accept unbuffered or registered memory. Mixing with other ECC types is not supported.

Verify platform supports DDR4 LRDIMM

Before ordering, confirm the system accepts DDR4 ECC load-reduced DIMMs at 288 pins and can address 128GB per module. The board and CPU must support 4Rx4 rank organisation and 1.2V operation. Backward compatibility with 2133, 2400, 2666 and 2933MHz speeds is specified, but the platform must explicitly list LRDIMM support. Desktop consumer motherboards and laptops will not work with this module.

Questions sur cet article

What DDR4 speed and CAS latency does this 128GB module run at?

It operates at DDR4 3200 (PC4-25600) with a CAS latency of CL22.

What physical slot and form factor does this LRDIMM require?

It uses a 288-pin DDR4 LRDIMM form factor and needs a server or workstation motherboard that supports load-reduced memory.

How is this module installed and what common mistake should be avoided?

Insert it into a compatible 288-pin DDR4 slot; do not mix it with unbuffered or registered ECC DIMMs, as load-reduced memory must match the existing memory type.
