128GB DDR4 2933MHz ECC LRDIMM

This 128GB DDR4 2933MHz ECC LRDIMM module targets administrators upgrading HPE servers that require load-reduced registered memory. The single stick delivers 128GB capacity at PC4-23400 speed with CL21 latency and 1.20V operation. It replaces the listed HP part numbers for compatible enterprise platforms.

288-pin DIMM installation and common issues

The module uses the standard 288-pin DDR4 DIMM form factor and seats like any registered server DIMM; align the key notch, press evenly until the ejectors click, and verify full insertion. Common issues include mixing LRDIMM with standard RDIMM or UDIMM in the same channel, populating slots in an order the firmware does not support, and failing to update BIOS before adding high-capacity ranks.

Compatibility checks before ordering

Confirm that your server model and BIOS revision explicitly support 128GB DDR4 2933MHz ECC LRDIMM modules with 2S4Rx4 (8Rx4) 3DS/TSV organisation. Check the maximum supported memory per socket and per channel, the qualified vendor list for the exact part numbers shown, and whether the platform requires matched populations across memory controllers.
