NEMIX RAM 32GB (4x8GB) DDR4 3200 ECC UDIMM CL22 1.2V memory upgrade

32 GB ECC UDIMM kit for ASRock server boards

This 32 GB kit contains four 8 GB DDR4 3200 modules built for ASRock Rack motherboards such as the E3C256D4ID2 and E3C256D4U-2L2T. ECC unbuffered operation protects data integrity in always-on server and workstation roles. The 1.2 V voltage and CL22 latency match the platform specifications exactly. IT teams who need validated compatibility for these specific boards will find the kit ready to deploy.

Tool-free DIMM installation with standard alignment

Each 288-pin UDIMM seats in the board’s DDR4 slots using the usual notch alignment; no special tools or carrier brackets are required. The modules ship without heat spreaders, so clearance around CPU coolers is maximised in dense chassis. A common mistake is mixing these unbuffered ECC sticks with registered DIMMs, which prevents the system from posting. Install all four modules in the matched channels shown in the board manual to enable full bandwidth.

ECC unbuffered DDR4 3200 at CL22 1.2 V

The single specification that decides fit is the combination of ECC unbuffered signalling, DDR4 3200 speed and CL22 timing at 1.2 V. Boards that require registered ECC or a different voltage will not accept this kit. Buyers who need registered DIMMs, higher frequencies or non-ECC memory for desktop platforms cannot use these modules.
