64 GB DDR4 ECC UDIMM kit

This NEMIX RAM kit delivers 64 GB of DDR4 ECC unbuffered memory across eight 8 GB modules. Each stick runs at 2666 MHz with CL19 latency at 1.20 V using a 288-pin UDIMM form factor. The modules use major OEM chips from Samsung, Micron or Hynix and are stress tested for stability in server and workstation environments.

Suited for ECC-capable servers and workstations

This memory is built for systems that require error-correcting code on unbuffered DDR4 slots. It fits IT professionals upgrading compatible servers, NAS units or workstations where data integrity matters. Builders needing registered or load-reduced DIMMs, non-ECC consumer memory, or speeds beyond 2666 MHz should look at other modules that match those requirements.

Check motherboard support for unbuffered ECC UDIMMs

Verify that your board accepts 288-pin DDR4 ECC unbuffered DIMMs and can run eight modules at 2666 MHz with CL19 timing at 1.20 V. Confirm the maximum supported capacity per slot and total capacity across all populated slots. Ensure the BIOS or firmware recognises 1Rx8 organisation and that no registered-only restriction applies.

Questions about this item

What motherboard slot and memory type are required for these 288-pin DDR4 ECC UDIMM modules?

A motherboard with DDR4 288-pin UDIMM slots that supports ECC unbuffered memory is required for the 8 x 8 GB kit to function.

Can these 2666 MT/s CL19 modules run with older DDR4 DIMMs at lower speeds?

Yes, the modules will downclock to match the slowest installed DIMM while maintaining 1.20 V operation across all slots.

How can I verify the full 64 GB kit is detected and ECC is active after installation?

Check the BIOS memory summary for 64 GB total and ECC status enabled, then confirm in the OS with a tool that reports ECC correction counters.
