ASUS server DDR4 2666 ECC UDIMM kit

This NEMIX RAM kit delivers 16 GB across two 8 GB unbuffered DDR4 2666 modules with ECC. It targets administrators upgrading ASUS server motherboards that require PC4-21300 CL19 1Rx8 DIMMs.

Check motherboard DDR4 ECC UDIMM support

Verify that your ASUS board accepts unbuffered ECC DDR4 at 2666 MT/s and 1.2 V. Confirm the CPU and chipset enable ECC on UDIMM slots. Ensure two free 288-pin slots are available for the dual-channel kit.

No heat spreaders or software included

Modules ship without heat spreaders for dense server layouts. The package contains only the two DIMMs; no configuration utilities or firmware tools are bundled. Installation relies on the platform BIOS to apply JEDEC timings.
