Capacity 128GB 4X32GB

  • 128 GB total capacity in a 4×32 GB kit
  • DDR5 5600 speed rated at PC5-44800
  • Low 1.10 V operating voltage for efficiency
  • CL46 CAS latency for responsive timing
  • Validated for ASRock Z790 PG Lightning motherboard

Capacity and configuration

This kit supplies 128GB of DDR5 memory arranged as four 32GB UDIMM modules. It is built for desktop systems that accept 288-pin DDR5 unbuffered non-ECC DIMMs and can run at the rated 5600 speed with CL46 timing at 1.1V.

Who this suits and who it does not

The kit targets owners of the ASRock Z790 PG Lightning motherboard who need the full 128GB capacity in a matched four-module set. Builders using a board with fewer than four slots, a different memory generation, or a requirement for ECC or registered modules should look at something else.

Deciding specification

The motherboard-specific validation for the ASRock Z790 PG Lightning is the single detail that confirms this kit will operate at the rated DDR5 5600 CL46 1.1V profile without further configuration.

Questions about this item

How do I verify the kit is running at 5600 MT/s and CL46 after installation?

Enter the motherboard BIOS and confirm the memory frequency reads 5600 MT/s with timings showing CL46; CPU-Z or similar tools will also display DDR5-5600 and the 46-cycle CAS latency once the system boots.

What exactly ships in the box and is anything else required?

The package contains four 32 GB DDR5 UDIMM modules for a total of 128 GB; no heat spreaders, cables or additional parts are included and nothing else is needed for installation.

Should I choose this 128 GB 4×32 GB kit or a different capacity for my ASRock Z790 PG Lightning?

This 128 GB kit (4×32 GB) matches the board's four-slot layout and validated DDR5-5600 CL46 specification; select it when you need the full 128 GB capacity, otherwise pick a smaller kit that uses the same speed and latency.
