The RTX 4090 is the flagship graphics card from Nvidia’s next-generation Ada Lovelace architecture. It has been shown to be capable of some impressive overclocking results, with one sample hitting a boost clock of 3930 MHz.
This was achieved by a user on the overclock.net forum, who used liquid nitrogen cooling to push the card to its limits. The overclock was stable in FurMark, a benchmarking tool that stresses the GPU.
The RTX 4090’s base clock is 1860 MHz, so this overclock represents a significant boost in performance. It is worth noting that this is an extreme overclock, But it is not something that most users will be able to achieve.
it does show the potential of the RTX 4090, it is likely that we will see even higher overclocks in the future. The RTX 4090 is already a very powerful card, but with overclocking, it can become even more so.
In addition to the boost clock, the user on overclock.net also increased the power limit of the card. And This allowed them to push the voltage higher, which in turn allowed them to achieve a higher clock speed.
The power limit of the RTX 4090 is 450 watts, but the user on overclock.net increased it to 500 watts. And This allowed them to push the voltage to 1.25 volts, which is the maximum safe voltage for the card.
The overclock was stable in FurMark, but it is not clear how stable it would be in real-world applications. It is possible that the card would crash or throttle under heavy load.
Overall, this is an impressive overclock, and it shows the potential of the RTX 4090. it is important to note that this is an extreme overclock, But it is not something that most users will be able to achieve.
