ASRock Z790 PG Lightning DDR5 UDIMM

This 16 GB DDR5 module is built for the ASRock Z790 PG Lightning motherboard and runs at 5600 MT/s with CL46 latency. The single-rank 1Rx8 layout uses major OEM DRAM from Samsung, Micron or Hynix. It is a non-ECC unbuffered UDIMM designed for desktop PC upgrades. The 288-pin form factor fits standard DDR5 slots on the target board.

Sustained-load behaviour at 1.10 V

Operating at the JEDEC-standard 1.10 V, the module maintains its rated 5600 speed under continuous workloads without requiring elevated voltage. The absence of a heat spreader means thermal performance depends on case airflow, but the low nominal voltage helps limit heat output during extended sessions. All units are stress-tested under load before shipping to verify stability.

Compatibility checks before ordering

Confirm your motherboard is the ASRock Z790 PG Lightning, as this kit is validated specifically for that model. Verify an available 288-pin DDR5 DIMM slot and that the BIOS is updated to a version supporting 5600 MT/s DDR5. The module is non-ECC and unbuffered, so it will not work in platforms requiring registered or ECC memory.

Questions about this item

Does the 1.10V operating voltage keep heat low when the module runs at 5600 MT/s all day?

The module is rated for 1.10V at 5600 MT/s, a standard DDR5 voltage that typically produces modest heat under sustained load.

Must the motherboard be an ASRock Z790 PG Lightning with a 288-pin DDR5 slot for this UDIMM to work?

This 288-pin DDR5 UDIMM is validated for the ASRock Z790 PG Lightning; other boards with DDR5 slots may work but are not confirmed by the supplier.

Can I add this 1Rx8 CL46 stick alongside an existing 5600 MT/s DDR5 module on the same Z790 board?

Mixing a 1Rx8 CL46 module with another 5600 MT/s DDR5 stick is possible, though the system will run at the looser timing of the slowest module.
