256 GB DDR5 ECC RDIMM Kit

This 256 GB kit contains eight 32 GB DDR5 4800 MHz CL40 registered ECC modules. It is built for the Supermicro H13SST-G motherboard and runs at 1.1 V. The 2Rx8 organisation matches the board's memory controller requirements.

Who This Suits

Administrators expanding a Supermicro H13SST-G server to its full eight-slot capacity need this exact rank, voltage and timing combination. Builders using consumer boards, unbuffered DIMMs, or a different DDR generation should look elsewhere.

Registered ECC Architecture

Registered buffering offloads the memory controller so all eight slots run fully populated at rated speed. ECC corrects single-bit errors on the fly, preventing silent data corruption in production workloads.

Questions about this item

How can I verify the 256GB kit is running at DDR5-4800 CL40 after installation?

Enter the system BIOS or use a hardware-monitoring utility to confirm the memory frequency reads 4800 MT/s, the CAS latency shows CL40, and all eight 32GB modules are detected at 1.10 V.

What comes in the box and what must I source separately?

The package contains the complete 256 GB kit — eight 32 GB DDR5 4800 MHz 2Rx8 registered ECC RDIMMs — so no additional memory modules are required; only the Supermicro H13SST-G motherboard and compatible CPU are needed.

Which version of this kit should I choose for the Supermicro H13SST-G?

Select the 256 GB (8 × 32 GB) DDR5-4800 PC5-38400 2Rx8 CL40 1.1 V registered ECC RDIMM kit with part number MR38400-328K8 — it is the exact-match specification validated for the H13SST-G.
