256GB ECC LRDIMM kit for HP ProLiant servers

This 256GB kit contains two 128GB DDR4 3200 CL22 modules built for HP ProLiant DL110 Gen10 Plus Telco and DL325 Gen10 Plus systems. It runs at 1.2V with 4Rx4 organisation and 288-pin LRDIMM form factor. The memory is intended for server and workstation platforms that require load-reduced ECC DIMMs.

Load-reduced ECC changes compatibility rules

Unlike standard unbuffered or registered ECC DIMMs, these load-reduced modules cannot be mixed with either type in the same system. The kit replaces HP part numbers P06037-B21, P06037-H21, P06037-K21, P43171-B21, P07652-B21, P07652-H21 and P25206-B21. Backward compatibility covers 2133, 2400, 2666 and 2933 MHz speeds.

4Rx4 rank density decides slot population

Each module presents a 4Rx4 configuration that determines how many ranks the memory controller sees per channel. This rank structure is the single specification that governs whether the kit will populate correctly in the supported ProLiant platforms. Buyers who need a different rank layout must choose another part.

Questions about this item

Will the 4Rx4 128 GB modules need any firmware updates or reconfiguration when I add them to the HP ProLiant DL325 Gen10 Plus?

The modules are JEDEC-compliant DDR4 3200 CL22 1.2 V ECC Load Reduced DIMMs designed for the DL110 Gen10 Plus Telco and DL325 Gen10 Plus, so they install without extra firmware steps.

What speed will the kit actually run at if the server only supports 2666 MHz DDR4?

The kit is backward compatible with 2133, 2400, 2666 and 2933 MHz, so it will down-clock to 2666 MHz automatically.

How much power does the 256 GB kit draw at 1.2 V when the server runs continuously?

Each 128 GB LRDIMM operates at 1.2 V; total power draw depends on the server's memory controller and workload, not on the modules alone.
