HP-compatible 32 GB DDR4-2133 LRDIMM

This 288-pin DDR4 module delivers 32 GB of ECC load-reduced memory at 2133 MT/s with CL15 latency. It is built for HP servers that require registered DIMMs and matches the OEM part number 753225-B21.

Thermals and power draw

Operating at 1.20 V, the module runs within standard DDR4 voltage limits for reduced power consumption in dense server configurations. Load-reduced buffering lowers electrical load on the memory controller, helping maintain stable thermals under sustained workloads.

Deciding specification

The 4Rx4 quad-rank organisation determines maximum capacity per channel and is the key factor when populating HP server memory slots. Systems that do not support 4Rx4 LRDIMMs cannot use this module.

Questions about this item

How do I install the 288-pin DDR4 LRDIMM and what step is often missed?

Align the notch on the 288-pin module with the slot key, press firmly until both side latches click, then verify the server BIOS recognises the full 32GB at DDR4-2133.

What maintenance or replacement will this 32GB ECC LRDIMM need over time?

No routine maintenance is required; the module carries a lifetime warranty so a replacement would only be needed if a memory test reports an uncorrectable error.

What limit appears first when this 4Rx4 LRDIMM runs under sustained load?

The CAS latency of CL15 at 1.20V sets the timing ceiling; sustained throughput cannot exceed the PC4-17000 data rate of 2133 MT/s.
