64 GB DDR5 kit for ASRock Z790 Nova WiFi

This 64 GB kit contains four 16 GB DDR5 modules rated at 5600 MT/s with CL46 timings at 1.1 V. It is built as a system-specific upgrade for the ASRock Z790 Nova WiFi motherboard, targeting builders who need maximum supported capacity on that platform.

288-pin UDIMM form factor and unbuffered design

Each module uses a standard 288-pin UDIMM edge connector and operates as non-ECC unbuffered memory. The 1Rx8 organisation allows direct installation into the board's four DIMM slots without registration buffers, simplifying the upgrade path for compatible desktop systems.

Low-voltage operation at 1.1 V

Running at the standard DDR5 voltage of 1.1 V keeps power draw modest during typical workloads. The modules ship without heat spreaders, relying on case airflow for cooling; thermal output remains low enough for quiet operation in most chassis configurations.

Questions about this item

What speed does the DDR5 5600 kit run at on the Z790 Nova WiFi?

The kit is rated DDR5 5600 (PC5-44800) and will operate at that speed when XMP is enabled in BIOS.

Will these 288-pin UDIMMs clear the CPU cooler on an ASRock Z790 Nova WiFi?

The modules have no heat spreader, keeping them at standard low-profile height for maximum cooler clearance.

Do I need to enable XMP in BIOS for the CL46 timings to apply?

Yes — install all four modules, enter BIOS, enable the XMP profile and save; the board will then run 5600 MT/s at CL46 1.1 V.
