Compatible DDR5 for ASRock LiveMixer

This 32 GB module runs at DDR5 4800 with CL40 latency and 1.1 V operation. It targets owners of ASRock Z790 LiveMixer or B650 LiveMixer boards who need a single-stick capacity increase without mixing kits.

Single-slot upgrade path

The 288-pin UDIMM fits one standard desktop slot and uses unbuffered non-ECC signalling. It requires a motherboard that supports DDR5 at 4800 MT/s and 2Rx8 organisation, freeing remaining slots for future expansion.

Ready-to-install stick

The package contains only the memory module itself. No heat spreader, software utilities or extra cables are included, so the builder simply seats the DIMM and configures the BIOS.

Questions about this item

Will the 1.10 V operating voltage limit how long I can run this module at full load?

The module is rated for 1.10 V at DDR5 4800 CL40 2Rx8; sustained full-load operation stays within that voltage specification.

How much heat does a 32 GB DDR5 4800 stick produce during all-day use and is a spreader needed?

This UDIMM has no heat spreader and runs at the standard 1.10 V DDR5 voltage; typical case airflow is sufficient for continuous operation.

What motherboard slot and chipset must I already have for this 288-pin UDIMM to work?

A desktop board with a DDR5 288-pin UDIMM slot — for example an ASRock Z790 or B650 LiveMixer — is required.
