48GB DDR5 4800 UDIMM Module

This 48GB DDR5 4800 module is a 288-pin unbuffered UDIMM built for desktop PCs. It runs at CL40 latency with a 1.1V operating voltage. The single-stick kit uses 2Rx8 organisation and carries no heat spreader.

For ASRock Z790 Taichi builders.

The module is validated for ASRock Z790 Taichi, Taichi Carrara and Taichi Lite motherboards. Buyers who require error-correcting code memory or registered DIMMs should look elsewhere. Systems limited to lower densities or different pin counts will not accept this stick.

Sustained load stability from factory stress testing

Every unit undergoes extended stress testing under load before shipping, so the rated 4800 MT/s speed and CL40 timings remain consistent during prolonged workloads. The 1.1V operation keeps power draw steady without thermal throttling on the bare PCB.

Questions about this item

Does my motherboard need a 288-pin DDR5 slot to accept this 48GB UDIMM?

Yes, this module uses the 288-pin DDR5 UDIMM form factor and requires a compatible DDR5 motherboard slot.

Will this 48GB stick run at 4800 MT/s on an ASRock Z790 Taichi motherboard?

It is validated for the ASRock Z790 Taichi series and will operate at its rated 4800 MT/s speed on those boards.

How can I confirm the module is running at CL40 latency after installation?

Check the memory timing readout in your BIOS or a system information utility; it should report CAS latency 40 at 4800 MT/s.
