Exact DDR5-5600 ECC RDIMM kit for Supermicro H13SSH

This 256 GB kit contains two 128 GB modules built to the DDR5 5600 standard with CL46 timing and 1.1 V operation. Registered ECC architecture and 2Rx4 organisation match the memory controller expectations of the Supermicro H13SSH motherboard so the full capacity is recognised at rated speed.

288-pin Registered form factor with major-OEM DRAM

The RDIMM modules use Samsung, Micron or Hynix chips without heat spreaders, keeping the profile low for dense server chassis. Registered buffering reduces electrical load on the controller when all slots are populated, while on-die ECC corrects single-bit errors before they affect workloads.

DDR5 platform limits require manual population

DDR5 RDIMM topology on this platform enforces strict slot-order rules and maximum capacity per channel that differ by BIOS revision. The kit delivers the specified 5600 MT/s rate only when installed according to the motherboard manual; otherwise the system may down-clock or fail to post. Buyers who need higher frequencies, lower latencies or non-ECC operation should look elsewhere.

Questions about this item

Does this kit run at the full DDR5 5600 speed on the Supermicro H13SSH?

Yes, the modules are DDR5 5600 (PC5-44800) with CL46 timing and 1.10 V, matching the memory controller specification so the board recognises the full 256 GB at rated speed.

What physical slot and form factor does the 288-pin RDIMM require on the H13SSH?

The kit uses 288-pin registered RDIMMs; the H13SSH provides standard DDR5 RDIMM slots with the matching key notch, so each 128 GB module seats directly without adapters.

Which population order should I follow when installing both 128 GB RDIMMs?

Install the first module in the slot designated as DIMM 1A (or CPU1 Channel A Slot 1) in the H13SSH manual, then the second in the matching slot on the next channel; this sequence lets the memory controller initialise the full 256 GB correctly.
