8GB DDR5 4800 Desktop Module

This OWC 8GB DDR5 4800 CL40 1.1V UDIMM is built for desktop PCs, workstations, NAS units and all-in-one systems that require JEDEC-standard DDR5 memory. The single-rank 1Rx16 288-pin module delivers 4800 MT/s bandwidth without a heat spreader.

Who This Suits And Who It Does Not

Choose this module when a system calls for non-ECC unbuffered DDR5 at 4800 MT/s CL40 and 1.1V. It matches the Crucial CT8G48C40U5 specification. Avoid it if the platform demands ECC, registered DIMMs, a different speed grade, or a lower CAS latency than 40.

The Spec That Decides Fit

The decisive specification is DDR5 4800 PC5-38400 CL40 at 1.1V in a 288-pin unbuffered non-ECC form factor. Only motherboards and controllers qualified for that exact JEDEC profile will run this module at its rated settings.

商品問答

What motherboard slot is required for the 288-pin DDR5 DIMM?

The module fits a standard 288-pin DDR5 UDIMM slot on a desktop or workstation motherboard that supports DDR5 memory.

Can I mix this CL40 4800 MHz stick with slower DDR5 modules already installed?

Yes, the system will run all modules at the speed and timings of the slowest installed kit, so this 4800 MHz CL40 stick will down-clock to match older DDR5.

How do I verify the module is running at 4800 MHz CL40 after installation?

Open Task Manager or a tool like CPU-Z and confirm the memory speed shows 4800 MHz with CAS latency 40 at 1.1 V.
