Exact-fit DDR5 ECC RDIMM kit for Supermicro H13DSH

This 64 GB kit delivers four 16 GB DDR5 4800 registered ECC modules at 1.1 V and CL40. It matches the rank, voltage and timing the H13DSH memory controller expects so every slot is recognised at full capacity and rated speed.

Four ranks of 1Rx8 give 64 GB total capacity

Registered architecture offloads the controller so all four slots run fully populated at DDR5 4800. ECC corrects single-bit errors on the fly to prevent silent data corruption. The kit stops at 64 GB; larger configurations need a different part number.

288-pin RDIMM form factor

Samsung, Micron or Hynix components populate the bare modules for enterprise reliability. The registered DIMM layout fits only RDIMM slots — not UDIMM or SODIMM — and the low-profile height suits dense server chassis. Lifetime replacement warranty and US-based technical support back the kit.

Questions about this item

Will this 64GB DDR5-4800 1Rx8 RDIMM kit work in a Supermicro H13DSH that already has older DDR5 modules installed?

Mixing this 1.1V CL40 288-pin registered ECC kit with other DDR5 modules may prevent the server from running at the rated 4800MHz speed or full 64GB capacity; the H13DSH manual specifies exact population rules for matched kits.

How can I confirm the kit is running at DDR5-4800 CL40 1.1V with ECC active after installation?

Enter the BIOS or use a tool such as dmidecode to verify each 16GB module shows 4800MHz, CL40 timings, 1.1V, registered ECC, and 1Rx8 organisation.

Does the package include only the four 16GB RDIMMs or are heatsinks and installation hardware also supplied?

The box contains the 64GB 4x16GB DDR5-4800 CL40 1.1V ECC RDIMM kit only; no heat spreaders or extra mounting hardware are included.
