256GB DDR5 ECC RDIMM kit for Supermicro H13DSH

This 256GB kit contains eight 32GB DDR5 4800 RDIMM modules rated CL40 at 1.10V. The 2Rx8 registered ECC design matches the Supermicro H13DSH motherboard's requirements for full-capacity operation. It is built for servers that need registered memory with error correction across all populated slots.

Check your motherboard manual for population rules

Verify the H13DSH manual for approved DIMM population order and maximum supported capacity per channel before ordering. Confirm the board requires 288-pin registered DDR5 RDIMMs and not unbuffered or SODIMM variants. The kit will only run at its rated speed when installed in the correct slots.

Registered ECC design offloads the memory controller

The registered architecture reduces electrical load on the memory controller so all eight slots can run fully populated at 4800 MT/s. ECC corrects single-bit errors in flight to prevent silent data corruption. No heat spreaders are included, so ensure your chassis airflow meets the server's thermal design.

Questions about this item

What comes in the 256GB kit and is anything else required?

The kit contains eight 32GB DDR5 4800 CL40 288-pin ECC Registered RDIMM modules. No additional parts are needed for installation on a compatible Supermicro H13DSH motherboard.

How do I decide between this 256GB kit and a smaller capacity?

Choose the 256GB (8 x 32GB) kit when your Supermicro H13DSH board supports full population at DDR5-4800 and you need the maximum registered ECC capacity this kit provides.

Will the DDR5-4800 CL40 rating run at that speed once installed?

Yes, the modules are spec-matched to the Supermicro H13DSH memory controller so the 2Rx8 registered ECC DIMMs operate at the rated 4800 MT/s with CL40 timing at 1.1V.
