ASUS-compatible DDR4 2666 kit

This NEMIX RAM kit supplies 32GB of DDR4 2666 memory across four 8GB UDIMM modules. It is built for desktop PCs that use ASUS motherboards and accept non-ECC unbuffered DIMMs at 1.2V. The CL19 timing and 1Rx8 organisation are set for standard JEDEC operation without manual tuning.

Desktop upgraders targeting ASUS platforms

The kit suits owners of compatible ASUS desktop boards who want a straightforward capacity increase to 32GB. It is not for systems that require registered or ECC memory, nor for builds limited to two DIMM slots. Buyers needing speeds above 2666MT/s or lower latencies should look at other modules.

DDR4 2666 288-pin UDIMM interface

The decisive specification is the DDR4 2666 288-pin UDIMM form factor with non-ECC unbuffered signalling at 1.2V. Only motherboards that explicitly support this exact memory type will recognise and run the kit at its rated 2666MT/s CL19 settings.

Questions about this item

Will the 2666MHz speed and CL19 timings work with my existing DDR4 modules that run at a lower frequency?

The kit runs at DDR4-2666 (PC4-21300) with CL19 latency at 1.2V; the motherboard will automatically down-clock all installed DIMMs to the speed of the slowest module.

How can I verify the kit is running at the rated 2666MHz and CL19 after installation?

Enter the UEFI/BIOS or open a system-info utility and check that the memory frequency reads 2666MT/s and the CAS latency shows 19.

Does the MD21300-818K4 package include only the four 8GB UDIMMs or are any cables or tools supplied?

The box contains only the four 8GB 288-pin DDR4 UDIMM modules; no cables, screws or tools are included.
