32 GB DDR5 module for ASRock Z790 Lightning WiFi

This single 32 GB DDR5 UDIMM runs at 4800 MT/s with CL40 latency at 1.1 V. It is built for desktop PCs using the ASRock Z790 Lightning WiFi motherboard and suits users adding capacity to a compatible platform.

Fits a single 288-pin DDR5 slot on the target board

The unbuffered, non-ECC module installs directly into one DIMM slot without extra power or cooling hardware. Its 2Rx8 organisation leaves remaining slots free for further expansion if the motherboard supports it.

Suits builders upgrading the named ASRock

Buyers needing ECC error correction, registered buffering, a heat spreader, or a different DDR generation should look elsewhere because this module provides none of those features.

Questions about this item

Does the 1.1 V operating voltage limit how far the DDR5 4800 module can be pushed under sustained load?

The module is rated at 1.10 V standard voltage; running it continuously at higher voltages would exceed the specification and could reduce stability or lifespan.

How much heat does the 32 GB DDR5 4800 kit generate during all-day operation without a heat spreader?

Without a heat spreader the bare PCB relies on case airflow; typical DDR5 UDIMM power draw at 4800 MT/s stays modest, so standard chassis cooling is usually sufficient for continuous use.

Will this 288-pin UDIMM work in my ASRock Z790 Lightning WiFi board without any other hardware changes?

Yes — the 288-pin DDR5 UDIMM is designed for that motherboard; simply install it in a compatible DIMM slot and the system will recognise the 32 GB capacity at 4800 MT/s.
