32GB DDR4-2400 ECC registered RDIMM with CL15 latency and 1.2V operation for HP-compatible server upgrades
This 288-pin registered module delivers 32GB of DDR4 memory at 2400MHz with CL15 latency. It operates at 1.20V and uses a 2Rx4 organisation with major-brand chips. The part matches HP specification 862932-B21 for drop-in server upgrades.
The stick is built for systems that require ECC registered DDR4 memory and accept the 288-pin RDIMM form factor. It will not work in desktop boards that only support unbuffered non-ECC modules or in servers that need a different voltage or pin layout.
The single specification that decides fit is the combination of registered ECC operation, 2Rx4 rank structure and 1.20V voltage. If the motherboard calls for registered DDR4 with those exact parameters the module installs directly; otherwise it is incompatible.

This module needs a standard 288-pin DDR4 DIMM slot that supports registered ECC memory and 1.2V operation.
Yes, the module follows JEDEC DDR4 standards, so it can share channels with other registered ECC DIMMs provided the platform allows mixed ranks and capacities.
Check the BIOS memory information screen or use a tool like dmidecode to confirm the speed shows 2400 MT/s and the CAS latency reads CL15.
