For our manual overclocking tests, we used MSI Afterburner. Our best results are as below.
Overclocking the RTX 4070 Ti was surprisingly fun, and I got more out of it than I thought I would. For starters, I maximised the power limit to 119% (340W) and was able to successfully add 230MHz to the GPU. Increasing the voltage slider also helped, with the real-world clock speed increasing by about 45MHz.
Overclocking the memory, however, was absolutely nuts. I kept pushing it and it remained stable even at +2000MHz, which is as far as the slider will go in MSI Afterburner. I have no idea if I just hit the silicon lottery with my sample or if other 4070 Ti's will be able to do the same, but it was quite fun to keep pushing and pushing until I could go no further.
As a result of this extra frequency, the 4070 Ti was able to complete a 30-minute stress test, averaging 3090MHz – a pretty sizable increase over stock.
As a result of this overclock, we actually saw pretty decent gains – with a 10% boost in Cyberpunk 2077, 13% in Horizon Zero Dawn, and 12% in Resident Evil Village. This is the most success I've had overclocking Ada Lovelace, so it could be well worth doing if your sample is as capable as mine.
Power draw did also increase as a result of this overclock, by 13% – up to 272.8W. This scales pretty closely with the overall increase in performance so it's not like the overclock has improved efficiency, but I'd say the performance gain is worth it.
