512GB DDR5 ECC RDIMM Kit for Supermicro H13SRH

This 512GB kit contains four 128GB DDR5 4800 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13SRH memory controller expects. It targets administrators upgrading that specific motherboard to its maximum supported capacity with hardware validated for full-speed operation.

Registered 288-pin form factor

Each module uses the 288-pin RDIMM form factor this board requires, not UDIMM or SODIMM. The registered architecture buffers the command bus so all four slots can run fully populated at the rated 4800 speed, while on-die ECC corrects single-bit errors before they reach the operating system.

DDR5 4800 CL40 1.1V specification decides fit

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V, matching the board's qualified voltage and timing profile. Buyers whose platform requires a different speed grade, voltage or rank configuration cannot use this memory.

Questions about this item

Does the DDR5-4800 (PC5-38400) rating mean each module runs at 4800 MT/s?

Yes, every module in this kit is rated for 4800 MT/s, matching the PC5-38400 specification the motherboard expects.

Will these 288-pin RDIMMs fit the Supermicro H13SRH motherboard slots?

The board requires 288-pin Registered DIMMs; this kit uses exactly that form factor so each module seats correctly.

What is the correct population order when installing all four 128 GB modules?

Consult the motherboard manual for the approved DIMM population sequence; the board’s rules dictate which slots must be filled first.
