32GB DDR5 kit for ASRock Z790 PG Lightning

This 32GB kit contains two 16GB DDR5 modules rated at 5600 MT/s with CL46 latency. It is built as a Non-ECC unbuffered UDIMM for desktop systems validated on the ASRock Z790 PG Lightning motherboard. The kit targets builders upgrading that specific platform with 32GB of capacity.

Check motherboard manual and slot population

Verify that your ASRock Z790 PG Lightning motherboard supports DDR5 5600 unbuffered memory and confirm the recommended slot order for a two-module kit. Ensure the board firmware is current enough to recognise the 1Rx8 organisation at 1.1V. The modules use a standard 288-pin DDR5 UDIMM form factor.

Thermals noise and power draw

The modules operate at the standard DDR5 voltage of 1.10V and have no heat spreader, so airflow across the PCB handles cooling. With no active components on the DIMM, acoustic output is zero. Power draw scales with the 5600 MT/s data rate and CL46 timings under load.

Questions about this item

Does the kit include both 16 GB modules or do I need to buy a second stick separately?

The package contains two 16 GB DDR5 modules for a total of 32 GB, so no additional sticks are required.

Should I pick the 5600 MHz CL46 version or a different speed for my ASRock Z790 PG Lightning board?

This kit is validated at 5600 MHz with CL46 timing for that exact motherboard, making it the matched choice.

What does the 5600 MHz rating actually deliver once the memory is installed in the system?

The modules run at the standard DDR5 5600 MT/s data rate with 1.10 V voltage and CL46 latency out of the box.
