Review: KFA2 RTX 4080 SG 1-Click OC 16GB



Overclocking via MSI Afterburner :

Direction the latest version of the MSI Afterburner software, version 4.6.4 Beta 3. This is the overclocking software designed by MSI but will be compatible with other GPU brands. The software is really well designed but you will have to go through the advanced mode in order to have access to all the settings possibilities.

To test our overclocking, we are going to focus first on the Time Spy benchmark. Let’s go! We choose a maximum fan speed, we set the power limit to the maximum, i.e. 110% and we’re off! At first, we only push the GPU frequency in 50 MHz steps until the benchmark is not running anymore. Once we have a stable GPU frequency, we move on to increasing the memory frequency.

By default, at stock frequencies , our KFA2 RTX 4080 SG gets an overall score of 26218 points and 27980 points for the GPU score. The boost frequency reaches a maximum of 2850 MHz with the GPU temperature rising to 57.6 °C.

In the end, I was able to push the Boost frequency to 3000 MHz and the memory to 1500 MHz. This allows me to obtain excellent scores and thus to gain more points. The limit is around 3050 MHz, if the card hits higher, the benchmark crashes.

Of course, now that you have the maximum frequencies, you will have to test with the fans in AUTO and why not, redo a new ventilation curve in order to hold these new frequencies or close frequencies. Now, the overclocking performance will depend on your card.
