Exact-match DDR5 ECC RDIMM kit for Supermicro

This 128GB kit contains two 64GB DDR5 Registered ECC modules built to the Supermicro H14SST-GE memory-population rules. It installs as a matched pair so the server recognises full capacity at rated speed.

Registered 2Rx4 architecture at 1.1V CL52

The modules run at DDR5 6400 (PC5 51200) with CL52 latency and 1.10V voltage in a 2Rx4 registered layout. Registered buffering offloads the memory controller to keep every slot stable at full capacity while ECC corrects single-bit errors on the fly.

288-pin RDIMM form factor for populated server

The 288-pin RDIMM form factor fits the Supermicro H14SST-GE DIMM slots exactly, not UDIMM or SODIMM sockets. It frees the builder from guessing rank, voltage and timing, but requires consulting the motherboard manual for approved population order before installation.

Questions about this item

What does the 6400 MT/s rating mean once the kit is installed in the Supermicro H14SST-GE?

The modules run at DDR5-6400 (PC5-51200) so the memory controller sees the full rated data rate without down-clocking, delivering the bandwidth the board specifies for this population.

How does the 288-pin RDIMM interface limit what can be installed?

The board only accepts 288-pin Registered DDR5 RDIMMs; UDIMMs, SODIMMs or any other form factor will not seat or function.

What physical clearance does the 2Rx4 64 GB module need inside the chassis?

Each 64 GB stick is a standard-height 288-pin RDIMM with no heat spreader, so it fits the regular DIMM slots on the H14SST-GE without extra vertical space.
