8GB DDR5 Desktop Upgrade

This A-Tech module delivers 8 GB of DDR5 memory at 4800 MHz with a CL40 latency and 1.1 V operation. It is built as a direct replacement for Crucial CT8G48C40U5 and CT2K8G48C40U5 parts. The unbuffered, non-ECC DIMM fits standard 288-pin desktop slots.

Sustained Workload Behaviour

The module runs at the JEDEC-standard 1.1 V, so power draw and thermals remain steady during extended multitasking or large-file workflows. CL40 timing at 4800 MHz provides consistent bandwidth without the voltage spikes seen in overclocked kits. Quality-assurance testing validates reliability under continuous load.

288-Pin DDR5 Form Factor

Compatibility hinges on the 288-pin DDR5 DIMM interface; the module will only install in motherboards that explicitly support DDR5 memory. Verify your platform’s memory specification before purchase to ensure the correct generation and pin count match.

Questions about this item

How much power does the 8GB DDR5 4800 CL40 module draw at its 1.10V rating during all-day use?

The module runs at the standard DDR5 voltage of 1.10V, keeping power draw low and heat output minimal even under continuous load.

What motherboard slot is required for this 288-pin DDR5 DIMM to work?

A desktop motherboard with a DDR5 288-pin DIMM slot is required; the module will not fit other slot types.

Will this 4800MHz CL40 stick run stably alongside slower DDR5 modules already installed?

The system will clock all installed DDR5 memory to the lowest common speed and loosest timings, so this module will match the slower kits automatically.
