Exact-Match DDR5 Kit for Supermicro H13SSW

This 128 GB kit contains eight 16 GB DDR5-5600 registered ECC RDIMMs built to the precise rank, voltage and timing the motherboard expects. Each module runs at 1.1 V with CL46 latency and a 1Rx8 organisation so the memory controller recognises the full capacity at rated speed.

Capacity and Registered Headroom

Eight single-rank modules fill every slot while the registered architecture buffers address and command signals, letting the memory controller drive a fully populated system without signal degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption that would otherwise crash production workloads.

DDR5 RDIMM Interface Constraints

The 288-pin RDIMM form factor is required; UDIMM or SODIMM modules will not fit or function in this platform. Population rules and maximum supported capacities are defined by the motherboard manual, so the installer must verify the approved DIMM order before seating the kit.

Questions about this item

Will this DDR5-5600 ECC RDIMM kit run at full speed alongside existing DDR5-4800 modules in my Supermicro H13SSW?

Mixing different DDR5 speeds forces the memory controller to run all modules at the lowest common speed. The board will downclock this 5600 MT/s kit to match the slower modules.

How can I verify the kit is recognised as 128 GB at DDR5-5600 with ECC active after installation?

Enter the BIOS or UEFI and check the memory information screen. It should show 128 GB total, 5600 MT/s operating speed, and ECC status reported as enabled or active.

Does the MR44800-618K8 box include a heat spreader or any installation tools, or must I buy them separately?

The modules ship without a heat spreader. The kit contains only the eight 16 GB RDIMMs. No tools are included; a standard Phillips screwdriver is all that is needed for installation.
