System-specific DDR5 kit

This 32 GB kit contains two 16 GB DDR5 modules rated at 4800 MT/s with CL40 latency and 1.10 V operation. It is built for the ASRock Z790 Lightning WiFi motherboard and uses unbuffered, non-ECC 288-pin UDIMMs.

Sustained-load behaviour

Modules are stress-tested under load to verify stability during extended workloads. The 1Rx8 organisation and major OEM DRAM from Samsung, Micron or Hynix support consistent throughput without heat spreaders.

Deciding specification

CL40 latency at DDR5 4800 determines whether this kit matches your platform’s timing requirements. Buyers needing lower latency or higher data rates should select a different specification.

Questions about this item

How much power does the 32GB DDR5 4800 kit draw at its 1.10V operating voltage?

Each module runs at 1.10V, the standard DDR5 UDIMM voltage, so total power draw stays within the normal range for a 2x16GB kit at this speed.

What motherboard slot and chipset are required to run this 288-pin DDR5 UDIMM kit?

The kit needs a motherboard with DDR5 UDIMM slots; it is validated for the ASRock Z790 Lightning WiFi board.

Will the CL40 1Rx8 modules work alongside slower DDR5 sticks I already have installed?

The motherboard will run all installed DDR5 at the speed and timings of the slowest module, so adding this CL40 kit to slower sticks lowers overall performance.
