64 GB DDR5-4800 ECC RDIMM kit

This 64 GB kit contains four 16 GB DDR5-4800 registered ECC modules built for the Supermicro H13DSG-O-CPU motherboard. Each module runs at 1.1 V with CL40 latency and a 1Rx8 organisation. The 288-pin RDIMM form factor matches the board's registered memory slots exactly.

Who this suits and who should look elsewhere

Server administrators who need a validated, fully populated memory upgrade for this specific Supermicro platform will find the correct rank, voltage and timing pre-configured. Buyers who want non-ECC memory, UDIMM or SODIMM form factors, or a different capacity per module should look elsewhere.

Deciding specification — registered ECC

The combination of registered buffering, ECC error correction and 1Rx8 rank at 1.1 V is the single specification that determines compatibility with the H13DSG-O-CPU memory controller. If your system requires a different rank structure, voltage or unbuffered modules, this kit will not function correctly.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H13DSG-O-CPU motherboard slots?

Yes, the kit uses the exact 288-pin DDR5 RDIMM form factor the board requires, not UDIMM or SODIMM, so every module seats correctly in the server's memory slots.

What is the correct population order for the four 16 GB sticks on the H13DSG-O-CPU?

Install the modules following the motherboard manual's approved DIMM population sequence; the kit is spec-matched to the board's rules, so full 64 GB capacity is recognised when populated in that order.

Do these registered ECC modules need any firmware updates or battery-backed maintenance over time?

No firmware or battery maintenance is required; the registered ECC design corrects single-bit errors automatically, and the modules are covered by a lifetime replacement warranty if a hardware fault ever occurs.
