48GB DDR5 6400 ECC RDIMM

This 48GB DDR5 6400 Registered ECC RDIMM delivers 6400 MT/s at CL52 with 1.1V operation. The 2Rx8 dual-rank layout matches the memory controller expectations of the Supermicro H13SSW motherboard. It is built for servers that require registered architecture and on-die error correction to maintain data integrity under continuous load.

Replaces slower or smaller DDR5 RDIMMs

Upgrading from lower-capacity or lower-speed registered modules is worthwhile when the platform supports 6400 MT/s and the workload benefits from larger per-DIMM density. The jump makes sense for virtualization hosts, database nodes, or compute clusters that hit capacity limits before CPU limits. It does not suit systems that only accept unbuffered UDIMMs or that cap memory speed below the rated 6400 MT/s.

288-pin RDIMM installs in standard server slots

Installation follows the motherboard’s documented population order; the registered buffer ensures electrical loading stays within spec even with every slot filled. Common issues arise when mixing ranks or speeds across channels, or when the BIOS has not been updated to the version that validates 48GB 2Rx8 modules. Always verify the approved DIMM sequence in the H13SSW manual before seating the kit.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the Supermicro H13SSW motherboard slots?

Yes, the module is a 288-pin Registered DDR5 DIMM built to the H13SSW's required form factor and memory-population rules.

What is the correct installation step for this 2Rx8 Registered ECC module?

Power down the server, follow the H13SSW manual's approved DIMM population order, and seat the RDIMM firmly until the retention clips lock.

When should this 48GB DDR5 6400 CL52 kit be replaced?

Replace the kit if ECC logs report uncorrectable errors, the server fails memory diagnostics, or a capacity upgrade is required.
