NEMIX RAM 48GB DDR5 6400 CL52 2Rx8 1.1V ECC RDIMM Supermicro H14SST-GE

Targeted Server Upgrade

This 48GB DDR5 module is built for the Supermicro H14SST-GE motherboard. It delivers registered ECC memory that the board's memory controller recognises at full capacity and rated speed. The 288-pin RDIMM form factor matches the slot requirement exactly. System administrators expanding memory in compatible Supermicro platforms will find it fits the validated configuration.

Replacing Registered ECC Modules

The kit replaces older registered ECC DIMMs that cannot reach DDR5 6400 (PC5-51200) at 1.1V with CL52 timing. The jump is worth it when the motherboard supports this data rate and the 2Rx8 rank structure, allowing full population without downclocking. It is not for systems that require unbuffered UDIMMs, SODIMMs, or a different voltage and rank layout.

Build Integration

The module installs directly into the 288-pin RDIMM slots on the H14SST-GE following the board's population rules. Registered architecture offloads the memory controller so every slot can run fully populated at rated speed. ECC corrects single-bit errors on the fly to prevent silent data corruption. No heat spreader is included, so airflow in the server chassis must be adequate for bare DRAM. Consult the motherboard manual for supported capacities and installation order before purchase.
