DDR5 5600 kit for ASRock Z790 Nova WiFi

This 64 GB kit (2 × 32 GB) delivers DDR5 5600 speed at CL46 latency and 1.10 V for the ASRock Z790 Nova WiFi motherboard. It targets builders and IT professionals who need a validated, non-ECC unbuffered upgrade for that specific platform.

Low-voltage DDR5 operation at 1.10 V

The modules run at the standard DDR5 5600 data rate with a 1.10 V supply, keeping power draw and heat modest under typical desktop workloads. No heat spreader is fitted, so airflow across the 288-pin UDIMM slots handles cooling without added noise.

Two matched 32 GB modules in the box

The kit contains exactly two 2Rx8 UDIMMs tested together for the ASRock board, so dual-channel mode works immediately after installation. No extra software, cables or brackets are included — just the memory itself.

Questions about this item

How do I install the 288-pin DDR5 UDIMM modules on the ASRock Z790 Nova WiFi motherboard, and which slot order is correct?

Insert each 32GB stick into the DDR5 slots specified by the ASRock Z790 Nova WiFi manual — usually the second and fourth slots from the CPU — press down until the retention clips click, and ensure the notch aligns with the 288-pin key.

What maintenance or replacement will the 2Rx8 DDR5 5600 kit need over time?

No periodic maintenance is required; the modules have no heat spreader and run at 1.10V, so only reseat them if the system fails to POST after a move or BIOS update.

At what point does the CL46 latency limit sustained throughput on this 64GB kit?

The CL46 timing is the primary latency ceiling; under continuous heavy workloads the CAS latency dominates response time before bandwidth or voltage becomes a bottleneck.
