Capacity and fit

This 64 GB kit contains four 16 GB DDR5 UDIMMs built for the ASRock Z790 Riptide WiFi motherboard. Each module runs at 5600 MT/s with CL46 latency at 1.1 V. The unbuffered non-ECC design suits desktop builders who need a matched set for four-slot population.

Sustained-load behaviour

Modules use major OEM Samsung Micron Hynix chips tested under load for stability. The 1Rx8 organisation and standard JEDEC timing deliver consistent throughput during long rendering or compilation sessions without relying on overclock profiles.

Thermals noise and power

Bare modules without heat spreaders keep the profile low for tight CPU cooler clearance. Operating at 1.1 V limits power draw per DIMM while silent operation adds no acoustic load to the system.

Questions about this item

How much power does the 1.1 V DDR5 kit draw under sustained load?

The modules run at 1.10 V, the standard DDR5 operating voltage, so power draw scales with the 5600 MT/s data rate and CL46 timing rather than any elevated voltage.

Does the ASRock Z790 Riptide WiFi board need four free 288-pin DDR5 slots to use this 64 GB kit?

Yes — the kit contains four 16 GB UDIMMs and requires four available 288-pin DDR5 slots on the Z790 Riptide WiFi motherboard.

Will the CL46 latency cause issues when paired with older DDR5 modules running at lower speeds?

The motherboard will train all installed modules to a common speed and latency; mixing CL46 5600 MT/s sticks with slower DDR5 simply runs the whole array at the lowest common settings.
