64 GB DDR5 kit for Gigabyte B650 AORUS Elite AX

This 64 GB kit contains two 32 GB DDR5 UDIMM modules rated at 4800 MT/s with CL40 latency. It is built for the Gigabyte B650 AORUS Elite AX motherboard and targets desktop users who need higher capacity for multitasking or content workloads.

Verify DDR5 slots and memory QVL before ordering

Your motherboard must provide 288-pin DDR5 slots and run at 1.1 V to match this kit. Confirm the board's qualified vendor list includes 2Rx8 32 GB modules at 4800 speed so the system trains correctly at the rated timing.

Sustained load stability from factory stress testing

Each module undergoes extended stress testing under load to verify reliability during long sessions. The 1.1 V operation keeps thermals manageable without a heat spreader, allowing the kit to maintain its rated 4800 CL40 performance over time.

Questions about this item

Does the kit include both 32GB modules or must I buy a second stick separately?

The kit ships as a matched pair of two 32GB modules giving 64GB total so nothing else is required for a full installation.

Should I choose the CL40 4800MT/s version or look for a lower latency kit?

This kit runs at 4800MT/s with CL40 timing at 1.10V; it is the specification validated for the Gigabyte B650 AORUS Elite AX so selecting this version guarantees native compatibility.

What does the 4800MT/s rating mean once the memory is installed in the board?

The modules will operate at DDR5 4800 (PC5-38400) with CL40 latency at the standard 1.10V without any manual tuning needed.
