48GB DDR5 kit for Gigabyte B650 AORUS Elite AX

This single 48GB DDR5 4800 module is built for the Gigabyte B650 AORUS Elite AX motherboard. It targets desktop users who need a straightforward memory upgrade for that specific platform. The kit delivers 48GB of capacity in one unbuffered UDIMM. It suits workloads that benefit from a large single-module footprint.

DDR5 4800 speed and CL40 latency define

The module runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40 at 1.10V. This JEDEC-standard data rate sets the maximum throughput without overclocking. Builders cannot exceed this frequency on default BIOS settings. The 2Rx8 organisation and 288-pin interface are fixed by the DDR5 UDIMM form factor.

No heat spreader means direct airflow contact

The bare PCB design relies on case airflow for cooling rather than an integrated spreader. Installation follows the standard 288-pin DDR5 keying, so the module seats in any compatible UDIMM slot. The single-stick layout leaves three slots free on typical four-slot boards for future expansion. Major OEM chips from Samsung, Micron or Hynix underpin the build.

Questions about this item

Should I choose the 48GB single module or look for a multi-module kit for the B650 AORUS Elite AX?

The 48GB single module fills one slot and leaves three free for future expansion on the B650 AORUS Elite AX.

What does the DDR5 4800 CL40 rating deliver in daily use on this board?

It runs at 4800 MT/s with CL40 latency at 1.10 V, giving standard JEDEC bandwidth and response for everyday workloads.

Does the 288-pin DDR5 UDIMM interface limit speed on the B650 AORUS Elite AX?

The 288-pin DDR5 UDIMM slot caps the module at its rated 4800 MT/s; the board will not push it beyond that JEDEC speed.
