16 GB DDR4 ECC UDIMM for ASRock Rack boards

This 16 GB DDR4 3200 module runs at CL22 with a 1.2 V supply. It uses a 2Rx8 unbuffered ECC design on a 288-pin UDIMM form factor. The kit targets ASRock Rack motherboards such as the B550D4-4L and related B550D4 series models. It suits servers and workstations that require error-correcting memory.

Verify motherboard slot count

Confirm the board accepts unbuffered DDR4 ECC UDIMMs and has a free 288-pin slot. Check the qualified vendor list for 3200 MHz CL22 operation at 1.2 V. Ensure the system BIOS can enable ECC functionality with unbuffered modules. Mixed-rank populations may affect maximum speed on some platforms.

Ideal for ASRock Rack B550D4 builds needing ECC

Builders expanding compatible ASRock Rack servers gain single-module capacity with error correction. Buyers needing registered or load-reduced DIMMs should look elsewhere. Systems limited to non-ECC consumer memory cannot use this module. Multi-channel configurations require matching modules per channel.

Questions about this item

Does the 16 GB module arrive alone or with any extra parts?

The package contains one 16 GB DDR4 3200 CL22 288-pin ECC UDIMM and nothing else.

When should I pick this 3200 CL22 stick over a faster or lower-latency kit?

Choose it when your ASRock Rack B550D4 board requires ECC unbuffered memory at 1.2 V and you want validated compatibility.

Will the rated 3200 MT/s and CL22 timings run automatically on the supported motherboards?

Yes, the module operates at DDR4 3200 PC4-25600 with CL22 latency at the standard 1.2 V on the listed ASRock Rack platforms.
