48GB DDR5 4800 UDIMM for ASUS ProArt Z790-CREATOR

This 48GB DDR5 4800 module is built for the ASUS ProArt Z790-CREATOR motherboard. It targets professionals who need a single high-capacity stick to expand system memory for demanding workloads. The 2Rx8 unbuffered design operates at 1.10V with CL40 timing.

Installing the 288-pin UDIMM

Installation follows the standard desktop memory procedure: power down, open the case, align the notch and press firmly until the retention clips click. The module has no heat spreader, so clearance is rarely an issue. Common mistakes include seating the stick incompletely or mixing it with kits of different speed, voltage or rank configuration.

Check motherboard slot population limits

Before ordering, verify how many UDIMM slots your ProArt Z790-CREATOR has free and whether the board supports a 48GB single-rank-per-module density. Confirm the BIOS is updated to the latest version for full DDR5 4800 compatibility. Ensure you are not exceeding the maximum total memory the platform allows.

Questions about this item

How can I verify the module runs at DDR5 4800 CL40 1.10V after installing it in the ASUS ProArt Z790-CREATOR?

Enter the UEFI or use a tool like CPU-Z to confirm the memory reports 4800 MT/s, CAS latency 40 and 1.10 V on the 288-pin UDIMM.

What does the package contain and is anything else required for the upgrade?

The box includes one 48 GB 2Rx8 DDR5 4800 UDIMM; no extra cables, brackets or cooling parts are needed for installation.

Should I pick this 48GB 2Rx8 DDR5 4800 module or a different capacity for the ProArt Z790-CREATOR?

Choose this 48 GB stick when you want maximum capacity in a single slot; select a smaller module only if you need to populate multiple slots for channel bandwidth.
