64GB DDR4 Kit for Desktop Upgrades

This NEMIX RAM kit supplies 64GB of DDR4 memory in four 16GB modules. It is built for desktop systems that accept 288-pin unbuffered UDIMMs. The kit targets users who need a straightforward capacity increase for everyday workloads.

Capacity and Headroom at 2666 MT/s

The four modules run at 2666 MT/s with a CAS latency of CL19 and a voltage of 1.20V. This combination handles general multitasking and office applications comfortably. Memory-intensive tasks such as large-scale rendering or virtualisation may exhaust the available bandwidth before the capacity limit is reached.

DDR4 UDIMM Interface Constraints

The 288-pin DDR4 UDIMM interface defines the physical and electrical limits of this kit. It operates within the standard PC4-21300 specification without error correction or registered buffering. Motherboards must support non-ECC unbuffered DDR4 at this speed to use the modules at their rated data rate.

Questions about this item

Will this 64 GB kit fit a standard consumer desktop motherboard?

The kit uses 288-pin DDR4 UDIMM modules, the standard form factor for desktop boards that accept DDR4 memory.

Does the 2666 MHz speed require manual BIOS changes to run at the rated frequency?

JEDEC-standard DDR4-2666 operates at 1.20 V with CL19 timings, so most motherboards will configure it automatically without XMP.

Can I mix these modules with existing DDR4 sticks that have different capacities or timings?

Mixing capacities or CAS latencies is possible but not guaranteed; the board will run all modules at the slowest common speed and loosest timings.
