16GB DDR4 3200 ECC Registered RDIMM

This OWC module delivers 16GB of DDR4 3200 (PC4-25600) memory in a 288-pin registered DIMM format. It operates at CL22 latency and 1.2V with 2Rx8 organisation and on-die ECC. The stick is built to JEDEC specifications and matches Hynix HMA82GR7CJR8N-XN and HMA82GR7DJR8N-XN part numbers. It carries no heat spreader.

Suited for servers and workstations needing

This memory is designed for platforms that require registered ECC DIMMs and will not function in standard desktop boards that accept only unbuffered modules. It cannot be mixed with unbuffered memory in the same system. Buyers who need non-ECC or unbuffered DDR4 for a consumer motherboard should look at a different product.

Steady throughput under continuous server workloads

Registered buffering reduces electrical load on the memory controller, helping sustain bandwidth during prolonged multi-threaded tasks. ECC corrects single-bit errors on the fly, preventing data corruption during extended uptime. The 1.2V operation keeps thermals manageable without a heat spreader in adequately ventilated chassis.

Questions sur cet article

Does my motherboard need 288-pin DDR4 slots that support ECC registered RDIMMs to use this 16GB module?

Yes, this is a 288-pin DDR4 ECC registered RDIMM. It requires a motherboard with DDR4 slots that accept registered ECC memory and will not work in standard desktop boards that only take unbuffered DIMMs.

Can I add this 2Rx8 CL22 1.2V stick alongside older DDR4 registered ECC modules of different speeds or ranks?

Mixing ranks, speeds, or CAS latencies is possible but the system will run all modules at the slowest common settings. For best stability OWC recommends matching capacity, speed, and manufacturer across every installed DIMM.

How can I confirm the module is running at 3200 MT/s with ECC active after installation?

Enter the system BIOS or UEFI and check the reported memory speed and ECC status. Operating-system tools such as dmidecode on Linux or CPU-Z on Windows will also show 3200 MT/s, CL22, 1.2 V, and ECC enabled.
