Purpose-built server memory kit

This 256GB kit contains four 64GB DDR5-5600 RDIMMs built to the exact specifications the Supermicro H13SSH motherboard expects. Registered ECC modules with 2Rx4 organisation and CL46 timing deliver the capacity and error correction required for production workloads.

Verify population rules first

Confirm the board manual for approved DIMM population order, maximum capacity per channel and any BIOS version requirements before ordering. The 288-pin registered form factor is mandatory; UDIMM or SODIMM modules will not fit or function in this platform.

Sustained enterprise stability

Registered architecture reduces electrical load on the memory controller so all slots operate at rated speed when fully populated. On-die ECC corrects single-bit errors continuously, preventing silent data corruption during extended compute runs without thermal throttling.

Questions about this item

What does the 256GB (4x64GB) kit include and is anything else required?

The package contains four 64GB DDR5-5600 ECC Registered RDIMM modules (part MR44800-924K4). No additional memory parts are needed for a full 256GB installation.

Why choose the 256GB kit instead of a smaller capacity for the Supermicro H13SSH?

This kit matches the board's 288-pin RDIMM requirement, 2Rx4 rank, 1.1V voltage and CL46 timing so all four slots run at the rated DDR5-5600 speed.

What does the DDR5-5600 (PC5-44800) rating mean once the modules are installed?

The memory controller will recognise each DIMM at 5600 MT/s with CL46 latency, delivering the full 256GB capacity at the specified 1.1V operating voltage.
