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.

Questions about this item

How can I confirm the kit runs at DDR4 3200 with CL22 timings after installation?

Enter the system BIOS or use a tool like CPU-Z to verify the memory frequency reads 3200 MT/s and the CAS latency shows 22.

What does the package contain and are any extra parts required?

The box includes four 8 GB DDR4 3200 ECC UDIMM modules for a total of 32 GB; no additional components are needed for installation.

Which capacity version should I choose for an ASRock Rack board that supports 32 GB?

This 32 GB kit (4 × 8 GB) matches the 32 GB capacity listed for the compatible ASRock Rack motherboards.
