Server memory upgrade for Supermicro H13SSH

This 64GB DDR5 RDIMM is built as an exact-match upgrade for the Supermicro H13SSH motherboard. It targets system builders and IT teams who need registered ECC memory that the board recognises at full capacity without manual tuning.

Registered ECC with 2Rx4 organisation

The module uses a registered 2Rx4 layout at 1.10V with CL46 latency, the precise rank and timing the H13SSH memory controller expects. A UDIMM or different rank configuration will not be accepted by this platform.

Kit contains a single 64GB DIMM

The package delivers one 288-pin RDIMM so you can populate slots according to the motherboard's population rules. No heat spreader is included, and no software or cables are bundled with this memory-only kit.

Questions about this item

What does the DDR5 5600 (PC5-44800) rating mean once the module is installed in a Supermicro H13SSH?

The module runs at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V, so the memory controller recognises the exact rank, voltage and timing it expects and operates the DIMM at its rated speed.

How does the 288-pin RDIMM interface and registered ECC design affect operation?

The 288-pin Registered (RDIMM) form factor matches the board's required slot type, while registered architecture offloads the memory controller and ECC corrects single-bit errors on the fly for stable fully-populated operation.

What physical space and slot type are needed to fit this 64 GB module?

It requires a standard 288-pin DDR5 RDIMM slot on the Supermicro H13SSH motherboard; the module has no heat spreader, so it fits within normal DIMM clearance.
