Exact DDR5-6400 RDIMM kit for Supermicro H13SSW

This 256GB kit contains eight 32GB DDR5 6400 modules built to PC5-51200 speed with CL52 latency and 1.1V operation. Registered ECC architecture with 2Rx8 organisation provides the signal integrity and error correction required by server memory controllers. Modules use 288-pin RDIMM form factor and major OEM chips from Samsung, Micron or Hynix.

Verify motherboard manual for population rules

The Supermicro H13SSW requires Registered RDIMM modules, not UDIMM or SODIMM variants. Confirm the approved DIMM population order and maximum supported capacity per channel before ordering. Ensure the system BIOS is updated to a version that recognises fully populated DDR5-6400 Registered ECC configurations at rated speed.

Replaces partial or slower DDR5 RDIMM sets

Upgrading from a partially filled configuration or lower-speed DDR5 RDIMMs eliminates empty slots and raises bandwidth to the full PC5-51200 specification. The jump is worthwhile when workloads demand maximum registered ECC capacity and the board's memory controller supports eight 2Rx8 modules at 6400 MT/s without downclocking.

Questions about this item

Does the 256 GB kit ship as eight 32 GB modules or must I buy extra sticks?

The kit contains eight 32 GB DDR5 RDIMMs for a total of 256 GB; nothing else is required to reach that capacity.

Why choose the 256 GB 8×32 GB CL52 1.1 V version instead of a smaller kit?

This exact-match 256 GB kit uses 2Rx8 registered ECC modules at 1.1 V CL52, matching the Supermicro H13SSW population rules for full-speed operation.

Will the DDR5 6400 rating run at 6400 MT/s once installed in the H13SSW?

Yes, the modules are spec-matched to the board's memory controller so all eight slots operate at the rated DDR5 6400 speed when populated per the manual.
