128GB DDR4-3200 ECC LRDIMM
This 128GB DDR4-3200MHz ECC LRDIMM is built for enterprise servers that require high-density registered memory. The quad-rank 4Rx4 organisation delivers maximum capacity per slot for virtualisation hosts and database platforms. It operates at PC4-25600 speed with full error-correcting code protection.
Third-party HPE compatible alternative
The module is a Brute Networks part validated as 100% compatible with HPE part number P43171-B21. Buyers receive the same form factor, rank structure and DDR4-3200 rating without purchasing the original vendor SKU. A lifetime warranty from the third-party supplier covers the module itself.
4Rx4 quad-rank layout
The 4Rx4 configuration determines whether the memory controller can address the full 128GB in a single DIMM slot. Systems limited to dual-rank or single-rank modules will not recognise the capacity. Verify the platform memory-qualified vendor list for 4Rx4 LRDIMM support before ordering.

Questions about this item
Will the 4Rx4 ECC LRDIMM require any firmware updates or rank-specific configuration after installation?
The module is built as a direct equivalent to HPE part P43171-B21 and carries a lifetime warranty, so no additional firmware steps or rank configuration are needed beyond standard server memory setup.
At what point does the 4Rx4 organisation become the limiting factor under sustained heavy workloads?
With four ranks per DIMM the memory controller reaches its maximum rank count per channel first, which caps total capacity before bandwidth or latency limits appear.
How much extra heat and power does a 128 GB 3200 MHz LRDIMM add when the server runs continuously?
Load-reduced DIMMs buffer the address and command signals on the module itself, lowering electrical load on the CPU memory controller and keeping thermal output comparable to lower-capacity registered DIMMs during all-day operation.
