NEMIX RAM 384GB 4x96GB DDR5 6400 CL52 1.1V ECC RDIMM memory upgrade

Exact-match server kit

This NEMIX RAM kit delivers 384GB across four 96GB DDR5 RDIMM modules rated at 6400MHz with CL52 latency. It is built for administrators upgrading the ASRock Rack GENOA2D16NQM3-2Q motherboard and other platforms that require registered ECC memory in a 288-pin form factor. The 2Rx4 organisation and 1.1V operating voltage match the memory controller expectations for full-capacity recognition.

Registered ECC constraints

Registered (buffered) architecture reduces electrical load on the memory controller so all slots can run fully populated at the rated speed. ECC corrects single-bit errors automatically to prevent silent data corruption and unplanned reboots in production workloads. The DDR5 6400 standard sets the timing and voltage envelope; this kit operates strictly within those limits and will not function in boards that only accept unbuffered UDIMM or SODIMM modules.

Bare-module practicality

Modules ship without heat spreaders, keeping the profile low for dense server chassis where airflow is directed by the system fans. The 288-pin RDIMM keying prevents accidental insertion into incompatible desktop or laptop slots. Population order and maximum supported capacity vary by motherboard revision, so the system manual must be consulted before installation to confirm the approved DIMM sequence.
