OWC 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC RDIMM memory upgrade

256GB DDR4 ECC RDIMM for Supermicro

This single 256GB DDR4 3200 PC4-25600 CL22 8Rx4 288-pin 1.2V ECC Registered DIMM is built for Supermicro H12SSL and H12SSW motherboards. It targets server and workstation operators who need maximum capacity per slot. The module will not work in standard desktop systems or alongside unbuffered or load-reduced memory.

Sustained server workloads

ECC Registered architecture corrects single-bit errors and registers address and command signals to reduce electrical load on the memory controller. This design maintains data integrity and signal stability during continuous, multi-threaded operation typical of virtualization, database and compute clusters. JEDEC-compliant 3200 MT/s timing delivers consistent throughput without relying on short-burst overclocking headroom.

DDR4 platform ceiling

The DDR4 interface caps per-module bandwidth at the rated 3200 MT/s regardless of how many ranks are populated. Octal-rank density pushes the memory controller to its electrical limit, so maximum system capacity depends on the motherboard's qualified vendor list rather than the DIMM specification alone. Builders needing higher aggregate bandwidth must evaluate next-generation memory standards not supported by this platform.
