128GB DDR4 kit for ASUS boards

This NEMIX RAM kit delivers 128GB across four 32GB UDIMM modules built for ASUS Prime B660, B760, H770, Z790M and B560 motherboards. It runs at DDR4 3200 with CL22 latency at 1.2V. The unbuffered non-ECC design suits desktop workloads that need high capacity without server-grade features.

Sustained load behaviour

Modules use major OEM Samsung, Micron or Hynix chips stress tested under load to ensure reliability during extended sessions. The 2Rx8 organisation and standard 1.2V operation keep thermals steady without a heat spreader. JEDEC PC4-25600 timing provides stable throughput for rendering, virtualization or large dataset work.

Deciding specification

The 288-pin DDR4 UDIMM form factor with 2Rx8 rank and CL22 latency determines fit. Buyers needing ECC, registered modules or DDR5 cannot use this kit. Systems limited to lower maximum capacity per slot or different pin counts will not accept these modules.

Highlights

  • 128 GB total capacity from four 32 GB modules
  • DDR4 3200 speed rated at PC4-25600 bandwidth
  • Low 1.2 V operating voltage reduces power draw
  • CL22 CAS latency for responsive desktop performance
  • Validated for ASUS Prime B660, B760, H770, Z790M and B560 motherboards

Questions about this item

Does the 1.2 V operating voltage and lack of a heat spreader keep the kit cool during continuous operation?

The modules run at the standard 1.20 V for DDR4 and are unbuffered non‑ECC UDIMMs without a heat spreader; they rely on normal case airflow for cooling.

Which motherboard slots and chipset series must I already have to install this 288‑pin 3200 MHz kit?

You need a desktop board with four 288‑pin DDR4 slots that supports the ASUS Prime B660, B760, H770, Z790M or B560 series.

Will the 2Rx8 organisation and CL22 timing work with lower‑rank DDR4 modules I keep in the same system?

Each 32 GB stick is dual‑rank 2Rx8 at CL22; mixing ranks is possible but the motherboard will run all modules at the speed and timings of the slowest installed kit.
