Exact 256GB DDR5 kit for Supermicro H13SST-G

This NEMIX RAM kit delivers 256GB (8 x 32GB) of DDR5 6400 registered ECC memory. It is built for the Supermicro H13SST-G motherboard where 288-pin RDIMM modules with 2Rx8 rank and 1.1V operation are required for full-capacity recognition at rated speed.

Straightforward RDIMM installation

Modules seat in the standard 288-pin DDR5 slots. The registered design buffers the memory controller, allowing all eight slots to run fully populated. Common issues arise when DIMMs are inserted in the wrong population order or when the BIOS is not updated to support the full 256GB configuration.

Verify motherboard population rules first

Check the Supermicro H13SST-G manual for approved DIMM capacity per slot, required installation sequence, and any BIOS version needed for DDR5 6400 operation. The board must accept 2Rx8 registered ECC RDIMMs at 1.1V; otherwise the kit will not be recognised or will run at reduced settings.

Questions about this item

How can I verify the kit is running at DDR5 6400 with CL52 after installation?

Enter the system BIOS or use a hardware-monitoring utility to confirm the memory frequency shows 6400 MT/s and the CAS latency reads 52; the registered ECC design also lets the OS report corrected-error counts as a sign of healthy operation.

What does the package contain and is anything else required to use it?

The box includes eight 32 GB DDR5 288-pin RDIMM modules for a total of 256 GB; no extra cables, brackets or software are needed, but the Supermicro H13SST-G manual should be consulted for the correct DIMM population order.

Why choose this 256 GB eight-module kit instead of a different capacity?

This kit matches the exact 2Rx8 registered ECC specification and 1.10 V voltage the H13SST-G memory controller expects, ensuring full-speed recognition across all populated slots without mixing ranks or voltages.
