OWC 32GB DDR4 3200 ECC RDIMM

This OWC 32GB DDR4 3200MHz PC4-25600 ECC Registered RDIMM is built for servers and workstations that require registered error-correcting memory. The 288-pin module operates at 1.2V with CL22 latency and a 2Rx4 rank configuration. It matches Hynix part numbers HMA84GR7CJR4N-XN and HMA84GR7DJR4N-XN for direct replacement.

Verify platform compatibility before ordering

This memory will not work in standard desktop computers that use unbuffered DIMMs. Your system must support DDR4 ECC Registered RDIMMs specifically. Mixing registered and unbuffered modules is not supported. Confirm your motherboard or server documentation lists registered ECC DDR4 as a supported memory type before purchase.

Sustained load stability with ECC

ECC registered architecture corrects single-bit errors and detects multi-bit errors during continuous operation. JEDEC-standard compliance and 1.2V operation maintain signal integrity across full DIMM populations. The module is tested to meet or exceed OEM specifications for reliable throughput in multi-socket server workloads over extended periods.
