NEMIX RAM 32GB (2x16GB) DDR4 3200 ECC UDIMM CL22 1.2V 2Rx8 288-Pin Kit

System-specific DDR4 ECC kit

This 32 GB kit contains two 16 GB unbuffered UDIMMs built for ASRock Rack B550D4 motherboards. ECC protection helps maintain data integrity in server and workstation workloads. The modules run at 3200 MT/s with a CAS latency of 22 at 1.20 V. No heat spreader is fitted, keeping the profile low for dense chassis.

Capacity and headroom

The dual-rank 2Rx8 organisation gives 32 GB total across two slots, leaving additional DIMM slots free on four-slot boards for future expansion. Workloads such as virtualization, ZFS storage or database caching fit comfortably within this capacity. Very large in-memory datasets or heavy multi-tenant containers will exceed the available memory and require a larger kit or higher-density modules.

288-pin DDR4 ECC UDIMM interface

Compatibility is limited to the listed ASRock Rack B550D4 models including B550D4-4L, B550D4ID-2L2T, B550D4M, B550D4U and B550D4U-2T. Boards that require registered DIMMs, a different pin count or non-ECC memory will not accept this kit. Verify the exact motherboard model before purchase.
