A 128 GB DDR5 kit with four 32 GB UDIMMs running at 5600 MT/s CL46 and 1.1 V, validated for ASRock Z790 Nova WiFi motherboards

  • Total capacity128 GB (4 × 32 GB)
  • Rated speedDDR5 5600 (PC5 44800)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL46
  • Buffer typeUnbuffered
  • Rated voltage1.1 V
  • 128 GB total capacity across four 32 GB modules
  • DDR5 5600 speed rated at PC5-44800 bandwidth
  • Low 1.10 V operating voltage for efficient power draw
  • CL46 CAS latency with 2Rx8 dual-rank organisation
  • 288-pin unbuffered non-ECC UDIMM validated for ASRock Z790 Nova WiFi

Capacity and Configuration

This 128GB kit contains four 32GB DDR5 UDIMM modules for desktop systems. The unbuffered, non-ECC design targets standard consumer platforms. Builders who need maximum memory density in four slots will find the 2Rx8 organisation suitable for heavy multitasking and content creation workloads.

Compatibility Fit

The kit is validated for the ASRock Z790 Nova WiFi motherboard, so buyers with that exact board gain plug-and-play confidence. Systems requiring ECC error correction or registered modules cannot use this memory. Builders using other chipsets or four-slot boards without verified DDR5 5600 support should verify their motherboard QVL before purchasing.

Decisive Specification

The operating speed is DDR5 5600 (PC5-44800) with a CAS latency of CL46 at 1.10V. This JEDEC-standard data rate and timing combination determines whether the kit matches the platform's memory controller capabilities. If the target system demands a higher frequency or lower latency, this module will not meet that requirement.
