To do so, you have to start MSI Afterburner, pres Ctrl+F and you’ll see the voltage curve editor. By decreasing the voltage, you’re freeing more TGP for the increased clocks. We reached 1845 MHz for the core and 2063 MHz (8251 MHz effective frequency) for the memory and the GPU voltage was set to 0.856V. First, you have to find the limit of your GPU by overclocking the core solely, then you can do the same with the memory and when you find its limit, you can combine both clocks and if everything works you can start playing games or do some benchmarking to test additionally for stability. We decreased this value to 0.856V and after that, we have started adding some MHz to the core. The default voltage of the GeForce RTX 3080 (165W) that was hiding under the bonnet of the MSI GE76 Raider 11UH is 0.9V. The best possible scenario is to undervolt the GPU and then overclock it. Yep, the GeForce RTX 3080 (165W) is a thirsty fella and when you increase the core and memory clock greatly without decreasing the voltage, this will result in some sort of throttle and that will limit the performance gain from the OC. This is the most pain-free method but by doing this, you’ll be out of TGP in a short time. In Windowed mode you can access safely MSI Afterburner and you can change the frequencies on the fly.Īs we said, you can try to increase the core clock as well as the memory frequencies whiteout playing with the voltage. In our case, we were using Unigine Heaven in Windowed mode at 1080p resolution with every setting bumped to the max. The easiest way is to increase the core frequency slightly and to test for stability. So, basically overclocking a mobile Ampere GPU doesn’t require a rocket scientist degree – you need to install MSI Afterburner or some other similar software that can overclock the GPU chip (most manufacturers have their own OC apps). Unfortunately, we didn’t have plenty of time for the testing, but we were able to overclock the GPU and we have done some OC tests. How to overclock the GeForce RTX 3080 (165W)
