128GB DDR5-4800 ECC RDIMM for Supermicro H14SSF

This 128GB registered DDR5 module runs at 4800 MT/s with CL40 latency at 1.1V. It uses a 2Rx4 organisation and 288-pin RDIMM form factor. The memory is built with major OEM DRAM and includes on-die ECC for error correction.

Suited for Supermicro H14SSF server upgrades

The module matches the board's required RDIMM form factor, registered architecture, and 1.1V operating voltage. Builders who need unbuffered UDIMM or SODIMM modules cannot use this part. Systems that do not support registered ECC memory should look elsewhere.

Registered 2Rx4 ECC at 1.1V decides fit

The registered buffer and 2Rx4 rank configuration offload the memory controller for full-capacity operation across populated slots. ECC corrects single-bit errors in flight. If the platform requires unbuffered memory or a different voltage, this module will not function.
