NEMIX RAM 8GB DDR4 3200 ECC UDIMM

This is an 8GB DDR4 3200 ECC unbuffered UDIMM built for ASRock Rack motherboards. It runs at 1.2V with CL22 latency and a single-rank 1Rx8 organisation. The module uses major OEM chips from Samsung, Micron or Hynix and has no heat spreader.

Check motherboard model and DDR4 ECC support

Verify that your board is an ASRock Rack E3C252D4U, E3C252D4U-2T or E3C252D4ID-2T. Confirm the system accepts DDR4 ECC unbuffered UDIMMs at 3200 MT/s and 1.2V. Ensure a free 288-pin DIMM slot is available and that the BIOS is current for memory compatibility.

Suits ASRock Rack server builds needing ECC

This module fits administrators upgrading or repairing the listed ASRock Rack platforms where ECC data integrity is required. Builders using consumer motherboards without ECC support or boards that demand registered DIMMs should look elsewhere. Users needing higher capacity per slot or lower latency than CL22 should consider other specifications.

Questions about this item

Does the package include only the single 8 GB DDR4 3200 ECC UDIMM or any extra accessories?

The box contains one 8 GB DDR4 3200 ECC UDIMM module; no cables, brackets or additional components are supplied.

Should I choose the CL22 1Rx8 version or look for a different latency or rank?

This module is CL22 with a single 1Rx8 rank; select it when your ASRock server board requires that exact timing and rank configuration.

What does the 3200 MT/s rating mean once the module is installed in a compatible ASRock server?

The memory will run at up to 3200 MT/s (PC4-25600) provided the motherboard and processor support that speed; otherwise it will operate at the highest supported rate.
