Gigabyte B650 AORUS Elite AX memory upgrade

This 32 GB DDR5 module is validated for the Gigabyte B650 AORUS Elite AX motherboard. It targets builders who need a single high-capacity stick for that specific board. Systems requiring ECC or registered memory cannot use this unbuffered non-ECC kit.

Sustained workload behaviour

The module runs at DDR5 4800 with CL40 latency at 1.1 V. Major OEM Samsung, Micron or Hynix chips are stress-tested under load to maintain stability during extended sessions. The 2Rx8 organisation supports consistent throughput without a heat spreader.

Build and daily use

A bare 288-pin UDIMM PCB fits standard desktop slots and leaves clearance for large CPU coolers. Single-stick packaging simplifies installation and leaves three slots free for future expansion. Lifetime replacement warranty backs the tested compatibility.

Questions about this item

Does the 1.10 V operating voltage keep heat and fan noise low during all-day workloads?

The module runs at 1.10 V, the standard DDR5 voltage, so power draw and heat output stay modest even under sustained load.

My motherboard has 288-pin DDR5 slots — is that the only requirement to install this stick?

Yes, the 288-pin DDR5 UDIMM form factor matches the board slots; no extra hardware or adapters are needed.

Will this CL40 4800 MT/s module run stably in a Gigabyte B650 AORUS Elite AX that already has slower DDR5 installed?

The board will clock all installed DDR5 to a common speed, so this stick will operate at the speed of the slowest module present.
