DDR5 memory kit for ASRock Z790 and B650 LiveMixer

This 32GB kit contains two 16GB unbuffered UDIMM modules built for DDR5 platforms. It runs at 4800MHz with a CL40 latency at 1.1V. The kit is validated for ASRock Z790 LiveMixer and B650 LiveMixer motherboards.

Builders upgrading compatible ASRock LiveMixer

Suitable for users adding 32GB of DDR5 memory to a Z790 or B650 LiveMixer system. Not for buyers who need ECC error correction or registered modules. Not for systems that require a heat spreader on every module.

288-pin DDR5 UDIMM form factor

Each module uses the standard 288-pin DDR5 UDIMM layout and operates at 1.1V. The physical pin count and voltage are the key specifications that determine whether the kit fits the motherboard slots.

Questions about this item

Does the 1.10V DDR5 kit run cooler and quieter than higher-voltage modules during all-day workloads?

Operating at 1.10V, the kit draws less power and generates less heat than higher-voltage DDR5, so system fans stay quieter during sustained use.

Must the motherboard be an ASRock Z790 or B650 LiveMixer for this 288-pin UDIMM kit to function?

The modules are validated for ASRock Z790 LiveMixer and B650 LiveMixer boards; other DDR5 motherboards may work but are not guaranteed by the vendor.

Will the CL40 4800 MT/s sticks downclock smoothly if paired with older DDR5 memory running at lower speeds?

Yes, DDR5 memory controllers automatically negotiate the lowest common speed and latency, so the kit will downclock to match slower modules.
