32GB DDR4 ECC RDIMM for HP Servers

This 32GB DDR4 2933MHz ECC registered DIMM is built for HP server and workstation platforms that require registered memory with error correction. It operates at 1.2V standard voltage with CL21 latency and a 2Rx4 rank configuration using major brand chips. The 288-pin module fits DDR4 DIMM slots in compatible systems.

Not for desktop PCs or non-ECC platforms

This module is designed for systems that specifically support ECC RDIMM memory and will not function in standard consumer desktop motherboards that require unbuffered non-ECC DIMMs. Buyers who need memory for gaming PCs, laptops, or workstations without registered memory support should look at different memory types. Systems limited to lower capacities per slot or different voltage requirements are also unsuitable.

Registered ECC with 2Rx4 organisation

The registered ECC design with dual-rank 2Rx4 organisation is the critical specification that determines compatibility with the target HP server platforms listed in the part numbers. This combination of error correction, registered buffering, and rank structure must match the system memory requirements exactly for the module to be recognised and operate correctly.

Questions about this item

My server takes 288-pin DDR4 DIMMs — will this 32GB module fit?

Yes, it is a 288-pin DDR4 DIMM, the standard form factor for DDR4 server memory.

I already have CL19 RDIMMs installed — can I mix them with this CL21 module?

Mixing different CAS latencies is possible, but the system will run all modules at the slowest timing, here CL21.

After installation, how do I confirm ECC is active on this 32GB stick?

Check the BIOS memory information or run a tool such as dmidecode; it should show ECC type as Registered ECC for this module.
