Supermicro H13SST-G DDR5 256GB kit

This 256GB kit provides four 64GB DDR5 5600 RDIMM modules built for the Supermicro H13SST-G motherboard. Registered ECC operation with 2Rx4 organisation and 1.1V voltage matches the platform's memory controller requirements for full-capacity recognition.

Installation fits 288-pin RDIMM slots only

The modules use the 288-pin RDIMM form factor required by this board; UDIMM or SODIMM modules will not seat. Consult the motherboard manual for the approved population order before installing all four slots to avoid a no-post condition.

DDR5 5600 bandwidth and population limits

The PC5-44800 interface runs at 5600 MT/s with CL46 latency when the memory controller supports the full 2Rx4 load across every channel. Maximum capacity and speed depend on the CPU and BIOS revision installed in the H13SST-G system.

Questions about this item

How do I verify the kit is running at DDR5 5600 CL46 with ECC active after installation?

Enter the BIOS or UEFI and confirm the memory speed reads 5600 MT/s, CAS latency shows 46, voltage is set to 1.10 V, and ECC is reported as enabled for all four 64 GB modules.

What ships in the box and do I need any extra parts to install it in a Supermicro H13SST-G?

The box contains the 256 GB kit as four 64 GB 288-pin DDR5 RDIMMs; no additional components are required for installation in the supported motherboard.

Which capacity and rank configuration should I select for full 256 GB support on this board?

Choose the 4 x 64 GB 2Rx4 kit (part number MR44800-924K4) to reach 256 GB with the registered ECC layout the H13SST-G expects.
