Server-grade DDR5 kit for Supermicro GPU SuperServer

This NEMIX RAM kit delivers 768 GB across six 128 GB DDR5 RDIMM modules rated at 6400 MHz CL52. ECC and registered buffering provide the data integrity required by the Supermicro GPU SuperServer SYS-422GS-NBRT-LCC.

Straightforward DIMM installation

The 288-pin RDIMMs install in minutes by seating each module firmly until the retention clips engage. The main risk is populating slots in an order the motherboard firmware does not recognise, which can prevent the system from posting.

Verify slot count and firmware before ordering

Confirm the server has at least six DDR5 RDIMM slots available and that the BIOS supports 128 GB 2Rx4 registered modules at 1.1 V. Without the correct slot count and firmware revision the kit will not be recognised.
