Server DDR5 ECC RDIMM

This 128GB registered DDR5 module is built for the Supermicro H14DST-F motherboard. It targets system administrators and integrators who need guaranteed compatibility and error-correcting stability in a production server environment.

Registered 2Rx4 architecture

The single specification that decides fitment is the registered 2Rx4 organisation combined with 1.1V operation and CL52 timing at 6400 MT/s. Only a motherboard wired for registered DDR5 RDIMMs with this exact rank structure and voltage will initialise the module at full capacity and rated speed.

Keyed 288-pin installation

The 288-pin RDIMM keying prevents insertion into UDIMM or SODIMM slots, so physical mis-installation is unlikely. What usually goes wrong is ignoring the motherboard manual's population order or maximum capacity per channel, which can leave the module unrecognised or running at a reduced speed.

Questions about this item

How does the DDR5 6400 speed behave once the module is installed in the Supermicro H14DST-F?

The memory controller recognises the exact 2Rx4 rank, 1.1V voltage and CL52 timing, so the module runs at its rated 6400 MT/s with full 128GB capacity.

What does the 288-pin RDIMM form factor limit when populating the board?

The registered 288-pin RDIMM fits only RDIMM slots — not UDIMM or SODIMM — and must follow the motherboard's population order for full-capacity operation.

What physical clearance does the module need inside the server chassis?

The stick uses a standard 288-pin RDIMM height with no heat spreader, so it fits any chassis that accepts full-height registered DIMMs.
