Exact-fit DDR5-5600 ECC RDIMM kit

This 256GB kit provides eight 32GB DDR5 5600 RDIMM modules built to the Supermicro H13SSH-E motherboard specification. Registered ECC operation at 1.1V CL46 with 2Rx8 rank organization matches the board's memory controller expectations for full-capacity recognition. The 288-pin form factor is the only type this platform accepts.

Verify board population rules and BIOS

Consult the Supermicro H13SSH-E manual for approved DIMM population order, maximum supported capacity per slot, and any required BIOS version before installing. Registered ECC RDIMMs cannot be mixed with unbuffered UDIMMs or SODIMMs. All eight slots must follow the vendor's sequence to reach the rated 5600 speed.

Replaces partial or slower DDR5 configurations

Upgrading from a smaller kit or lower-speed DDR5 modules is worthwhile when the workload demands full 256GB capacity at the board's native 5600 rate with ECC integrity. If the server already runs a matched 256GB set at CL46, the jump adds no benefit. Buyers needing more than 256GB total or a different form factor cannot use this kit.

Questions about this item

Does the 256GB kit ship as eight 32GB modules or do I need to buy anything else?

The kit contains eight 32GB DDR5 RDIMMs for a total of 256GB. No additional parts are required for installation on the Supermicro H13SSH-E.

Why choose the 256GB 8x32GB kit instead of a smaller capacity?

This kit fully populates eight slots with 2Rx8 registered ECC modules at 1.1V, matching the board's population rules for maximum supported capacity at DDR5-5600 CL46.

Will the DDR5-5600 CL46 rating run at that speed once installed in the H13SSH-E?

Yes. The modules are spec-matched to the motherboard's memory controller, so the 5600 MT/s data rate and CL46 latency are recognised and enabled at full capacity.
