Exact-match DDR5 server kit

This 128GB kit contains four 32GB DDR5 6400 RDIMM modules built to the 288-pin registered ECC standard. It runs at CL52 latency with a 1.10V operating voltage and 2Rx4 organization. The modules are specified for Supermicro X14SRA-T motherboards that require registered memory.

Suited for validated Supermicro platforms

Administrators populating a Supermicro X14SRA-T board with the exact rank, voltage and timing the memory controller expects will get full-capacity recognition at rated speed. Builders needing unbuffered UDIMMs, SODIMM form factors, non-ECC operation or different DDR generations cannot use this kit.

Registered ECC with 2Rx4 organization

The registered buffer offloads the memory controller so every slot runs fully populated while ECC corrects single-bit errors on the fly. This combination of registered signalling and dual-rank x4 chips is the single specification that determines whether the kit matches the motherboard's population rules.

Questions about this item

How do I install the 4x32GB DDR5 6400 2Rx4 RDIMM kit on the Supermicro X14SRA-T and what slot order does the manual require?

Power down the server, open the chassis, and follow the motherboard manual's exact DIMM population sequence for registered ECC modules; populate the specified slots in the order shown so the memory controller recognises all 128GB at DDR5-6400.

What maintenance or replacement will the 288-pin DDR5 ECC RDIMM kit need during its service life?

The modules have no moving parts and no heat spreader; under normal server airflow they require no periodic maintenance, and ECC corrects single-bit errors automatically, so replacement is only needed if a module fails.

What limit appears first when the 128GB DDR5-6400 CL52 1.1V registered kit runs sustained workloads?

The registered buffer and on-die ECC keep signal integrity at full population, so the first ceiling is the memory controller's maximum supported bandwidth at DDR5-6400 across all four slots.
