32 GB DDR4-2400 registered ECC RDIMM with 2Rx4 organisation and CL15 latency
This is a 32GB DDR4-2400 registered RDIMM built to HP part number 854596-B21 specifications. It operates at PC4-19200 speed with CL15 latency and 1.20V voltage using major-brand chips. The module features 2Rx4 organisation and ECC error correction for server reliability.
Buyers expanding or repairing compatible HP systems receive guaranteed compatibility with factory warranty preserved. Systems requiring unbuffered UDIMM modules or non-ECC memory cannot use this registered RDIMM. Builders needing different capacities or speeds should verify their platform requirements first.
The registered 2Rx4 ECC design at 1.20V is the single specification that determines fit. Only motherboards supporting registered DDR4 RDIMMs with this rank structure and voltage will accept the module. Verify your server documentation before purchase.

No, registered RDIMMs cannot mix with unbuffered UDIMMs; the server requires all slots to use registered memory.
Check the BIOS memory information screen; it should show 2400 MT/s, CL15 latency, 1.20 V and ECC enabled for each 32 GB module.
Only the 32 GB registered DDR4 DIMM is included; no cables, brackets or additional hardware are provided.
