Kit capacity and target platform

This NEMIX RAM kit supplies 128GB of DDR5 memory across four 32GB modules. It is built for desktop systems that use the ASUS TUF Gaming Z790-PLUS motherboard and accepts 288-pin UDIMM modules.

Who this suits and who it does not

The kit suits owners of the named ASUS board who need the full 128GB capacity and can use 2Rx8 unbuffered non-ECC modules at 5600 speed. Builders who require ECC error correction, registered DIMMs, lower CAS latency or a different pin count should choose another product.

Decisive specification

The modules run at DDR5 5600 (PC5-44800) with CL46 timing at 1.10V in a 2Rx8 unbuffered non-ECC configuration. This combination of speed, latency, voltage, rank structure and lack of ECC determines whether the kit will operate correctly in the target motherboard.

Questions about this item

Will the 1.10 V DDR5 modules add noticeable heat or power draw during all-day workloads?

At 1.10 V the kit runs at the standard DDR5 voltage, so power draw and thermals stay within normal desktop limits for 5600 MT/s operation.

What motherboard slot count and DDR5 support are required to use all four 32 GB UDIMMs?

You need a board with four 288-pin DDR5 UDIMM slots — such as the ASUS TUF Gaming Z790-PLUS WiFi — and a CPU memory controller that supports 128 GB at 5600 MT/s.

Can the CL46 2Rx8 sticks run alongside older DDR5 DIMMs I keep in the other slots?

Mixing ranks and latencies is possible but not guaranteed; the motherboard will train all modules to the slowest common speed and tightest shared timings.
