OWC 128GB DDR5 5600 CL46 4Rx4 ECC Registered RDIMM for Supermicro X13SET-PT X13SEVR-SP13F X13SEW-F X13SEW-TF

128 GB DDR5 ECC Registered DIMM

This 128 GB DDR5 module runs at 5600 MT/s with CL46 latency and 1.1 V operation. It is a 288-pin 4Rx4 registered DIMM built for Supermicro X13SET-PT, X13SEVR-SP13F, X13SEW-F and X13SEW-TF motherboards. The ECC registered design targets workstations, NAS units, servers and network switches that require error correction and signal buffering. It will not work in standard desktop boards or alongside unbuffered or load-reduced memory.

Sustained server workloads

Registered buffering reduces electrical load on the memory controller, allowing stable operation when all slots are populated under continuous demand. ECC circuitry corrects single-bit errors on the fly, preventing data corruption during long compute or storage tasks. JEDEC-standard 5600 MT/s timing delivers consistent throughput without relying on overclocking headroom that can degrade under heat.

Build and installation notes

The module lacks a heat spreader, so airflow across the DIMM slots is the only cooling path — verify chassis fan placement before deploying in dense configurations. A single 128 GB stick lets you reach high capacity with fewer occupied slots, leaving room for future expansion if the board supports additional ranks. JEDEC and RoHS compliance ensures the parts meet baseline industry specifications for server deployment.
