Exact-match server upgrade

This 1 TB kit contains 16 modules of 64 GB DDR5 RDIMM memory rated at 4800 MT/s, CL40, 1.10 V, 2Rx4 registered ECC. It is built for the Supermicro H13SSH motherboard and matches the rank, voltage and timing that board's memory controller expects.

Installation and common issues

The 288-pin RDIMM form factor fits only registered DIMM slots; UDIMM or SODIMM slots will not accept it. Full population requires following the motherboard manual's DIMM population order, otherwise the system may not recognise the full capacity or may fail to post.

Capacity and speed gate

The single specification that decides fitment is the 1 TB DDR5-4800 registered ECC configuration; if your platform requires a different capacity, speed, voltage or unbuffered modules, this kit will not work.

Questions about this item

How do I confirm the 1TB kit is recognised at full capacity and running at DDR5 4800 CL40 after installation?

Enter the BIOS or UEFI on the Supermicro H13SSH and verify that all sixteen 64GB modules show 1TB total, speed reads 4800 MT/s, and latency displays CL40 at 1.1V.

What ships in the box and do I need any extra parts to install this memory?

The box contains the 1TB kit — sixteen 64GB DDR5 288-pin ECC Registered RDIMM modules. No additional components are required for installation on the H13SSH.

Which version of this kit should I choose for a Supermicro H13SSH that requires Registered ECC RDIMMs?

Select the MR38400-924K16 kit: 1TB (16 x 64GB) DDR5 4800 PC5-38400 2Rx4 Registered ECC RDIMM at 1.1V CL40, the exact specification the H13SSH memory controller expects.
