768GB DDR5 ECC RDIMM Kit

This 768GB kit contains six 128GB DDR5 6400 Registered ECC RDIMMs built for the Supermicro H13SRH motherboard. The modules run at CL52 with a 1.10V operating voltage and use a 2Rx4 organisation. Registered buffering and on-die ECC protect data integrity in fully populated server configurations.

Who This Suits and Who Should Look Elsewhere

Administrators expanding a Supermicro H13SRH platform to its maximum supported capacity with validated registered DIMMs. Builders needing unbuffered UDIMMs, SODIMM form factors, non-ECC memory, or speeds other than DDR5 6400 should look elsewhere.

The Deciding Specification 288-Pin Registered DDR5

The motherboard requires 288-pin DDR5 RDIMMs at 6400 MT/s with registered buffering and ECC; this kit matches that exact electrical and mechanical interface. A mismatched pin count, buffer type, or data rate will prevent the system from booting or running at rated performance.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H13SRH motherboard slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the H13SRH memory slots exactly; UDIMM or SODIMM modules will not fit.

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

Follow the H13SRH manual's approved DIMM population sequence; the registered architecture allows full capacity per slot only when populated in the specified order.

How can I verify the ECC function is active after installation?

ECC is built into the 2Rx4 registered modules and operates automatically; check the BIOS or OS memory report to confirm ECC status is enabled.
