Six green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM 768GB 6x128GB DDR5 6400 CL52 2Rx4 RDIMM Supermicro H14DSG-O-CPU memory upgrade

SKU CH-KC16-AQQ5S

Supermicro H14DSG-O-CPU memory upgrade

This 768GB kit delivers six 128GB DDR5 6400 RDIMM modules built to the exact rank, voltage and timing the Supermicro H14DSG-O-CPU motherboard expects. Registered ECC architecture offloads the memory controller so every slot runs fully populated at rated speed while correcting single-bit errors on the fly.

Replacing lower-capacity RDIMM sets

Swapping smaller RDIMM kits for this 6x128GB configuration maximises the board's supported capacity in a single upgrade step. The jump is worth it when workloads need more simultaneous threads or larger in-memory datasets than the current population allows.

768GB capacity for dense workloads

Six 128GB dual-rank modules provide the headroom for virtualisation clusters, large database buffers and high-throughput compute jobs that scale with memory bandwidth. Headroom runs out when the platform's maximum supported DIMM count or per-channel limit is reached, so verify the manual before adding more.

Questions about this item

Will the 288-pin RDIMM modules fit the Supermicro H14DSG-O-CPU motherboard slots?

Yes, the kit uses the 288-pin Registered RDIMM form factor that the H14DSG-O-CPU requires; it is not a UDIMM or SODIMM.

What is the correct population order for the six 128GB modules on this board?

Consult the Supermicro H14DSG-O-CPU manual for the approved DIMM population sequence before installing all six modules.

Do these DDR5 modules need a heat spreader for sustained server workloads?

The modules ship without a heat spreader; adequate chassis airflow is required to keep the 1.1V DRAM within thermal limits.
