48GB DDR5 5600 module for ASRock Z790

This NEMIX RAM kit provides a single 48GB DDR5 5600 UDIMM built for the ASRock Z790 PG Lightning motherboard. It runs at 1.1V with CL46 latency and uses a 2Rx8 organisation on a standard 288-pin form factor.

Suits builders adding 48GB to a compatible board

It fits users who need exactly one 48GB DDR5 5600 stick for the named ASRock platform. Builders requiring ECC, registered DIMMs, a different voltage, lower latency, higher speed or multiple modules should look elsewhere.

5600 MT/s speed with CL46 timing

The module operates at DDR5 5600 (PC5-44800) with a CAS latency of CL46 at 1.1V. This speed and latency combination determines whether the memory matches the board's qualified vendor list and the builder's performance target.

Questions about this item

How do I install the 288-pin DDR5 UDIMM into the ASRock Z790 PG Lightning motherboard?

Align the module notch with the slot key, press down firmly until both retention clips click into place, and ensure the 1.10V DDR5 5600 stick seats fully in the correct channel.

What maintenance will the 48GB 2Rx8 CL46 module need over time?

No routine maintenance is required; keep the system free of dust and verify the memory runs at the rated 1.1V to preserve long-term stability.

What limit appears first when the PC5-44800 kit runs under sustained load?

The CL46 latency at 5600 MT/s defines the performance ceiling before bandwidth or voltage constraints become the bottleneck.
