16GB DDR4 3200 ECC Registered DIMM

This A-Tech module delivers 16GB of DDR4 3200 server memory with ECC and registered buffering. It operates at the standard 1.2V DDR4 voltage with CL22 latency. The 2Rx8 rank configuration uses major brand chips on a 288-pin DIMM form factor. It is built as a direct replacement for specific HP part numbers.

Suited for HP server upgrades needing registered ECC

Administrators expanding memory in compatible HP ProLiant or Apollo systems will find the correct spec match here. The registered design and ECC support meet enterprise stability requirements. Builders assembling custom white-box servers or consumer desktop PCs should look elsewhere because those platforms typically require unbuffered non-ECC memory.

Single module tested for reliability

Each stick undergoes quality assurance testing before shipment to verify dependable operation. The package contains only the memory module itself; no additional brackets, cables or software utilities are bundled. A-Tech backs the part with a lifetime warranty and provides US-based technical support for installation questions.

Questions about this item

What server platform must I already own to use this 288-pin DDR4 3200 RDIMM?

This module replaces HP part numbers P06031-B21, P07642-B21, P07642-H21, P07642-K21, P11443-191, P20501-001, P21673-001 and P25202-B21, so a system qualified for any of those parts is required.

How will this ECC RDIMM behave if I keep older DDR4 modules in the same server?

Registered DIMMs with ECC can be mixed only with other registered ECC modules of the same voltage; the memory controller will run all populated slots at the lowest common speed and timing.

How can I confirm this 2Rx8 CL22 module is operating correctly after installation?

Enter the BIOS or UEFI memory summary and verify that the slot shows 16 GB, DDR4 3200, registered ECC mode active and CL22 timings applied.
