For our manual overclocking tests, we used MSI Afterburner. Our best results are as below.
Overclocking the RTX 4060 Ti Twin X2 is pretty straight forward. Inno3D has locked the power limit at 100%, so we are simply unable to increase this, but we were still able to add 200MHz to the GPU and 1575MHz to the memory.
This brought average operating clock speeds up to 2880MHz, or a real-world increase of 180MHz compared to stock.
This overclock netted us performance gains in the region of 6-8%, which is pretty much what we'd expect nowadays. The Founders Edition did clock that tiny bit higher when pushed to its limit, but the difference is barely 1-2FPS.
Power draw did rise as a result of this overclock, but only by 9 Watts, and even then we are still under the 160W power limit of the RTX 4060 Ti so it's hardly a concern.
