NEMIX RAM 64GB (2x32GB) DDR4 3200 PC4-25600 CL22 ECC UDIMM memory upgrade

Capacity and form factor

This NEMIX RAM kit provides 64GB of DDR4 memory in a matched pair of two 32GB UDIMM modules. Each stick is a 288-pin unbuffered DIMM with ECC support and a 2Rx8 rank configuration. The modules operate at 1.2V and carry a CL22 latency rating at the rated 3200 MT/s speed. They are built using major-brand Samsung, Micron or Hynix ICs and ship without heat spreaders.

Compatibility focus

The kit is validated for specific ASRock Rack server motherboards including the E3C256D4ID2, E3C256D4ID-2T, E3C256D4U-2L2T and E3C256D4U-2L2T/BCM. It suits administrators upgrading those exact platforms where ECC unbuffered DDR4 is required. Builders using consumer desktop boards, registered-memory servers or laptops should look elsewhere because the form factor, buffering type or validation list will not match.

Deciding specification

The defining attribute is the DDR4 3200 ECC unbuffered UDIMM standard with a 2Rx8 organisation. Only systems that accept this exact module type, voltage and pin count can use the kit. Verifying the motherboard’s qualified-vendor list against the listed ASRock Rack models is the single step that confirms suitability.
