Capacity and fit

This NEMIX RAM kit delivers 768 GB across six 128 GB DDR5 RDIMMs built to the PC5-44800 standard. Registered ECC modules with 2Rx4 organisation run at 1.10 V and CL46 latency. The 288-pin form factor matches the Supermicro H14SST-G motherboard slot requirements exactly.

Who this suits

Server administrators who need the full 768 GB population on this specific board benefit from registered buffering that keeps every slot stable at rated speed. ECC correction prevents silent data corruption in production workloads. Builders using UDIMM-only platforms or boards that cannot address 128 GB ranks should select different memory.

Build integration

The kit occupies all six DIMM channels on the H14SST-G, so no additional modules are required to reach maximum capacity. Registered architecture reduces electrical load on the memory controller when fully populated. Verify the motherboard manual for approved population order and BIOS settings before installation.

Questions about this item

What motherboard slot layout does the Supermicro H14SST-G need to accept this 6-module 288-pin RDIMM kit?

The H14SST-G must provide six DDR5 288-pin RDIMM sockets and follow its documented population order so all 128 GB modules register at 5600 MHz with 1.1 V and CL46 timing.

Can I mix these 2Rx4 Registered ECC modules with other DDR5 RDIMMs already installed in the H14SST-G?

Mixing ranks or capacities is only supported if the motherboard manual lists the exact combination; otherwise the memory controller may down-clock or fail to recognise the full 768 GB.

How do I confirm the kit is running at the rated 5600 MT/s with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode to verify speed shows 5600 MT/s, voltage reads 1.1 V, and ECC status reports enabled.
