Overclocking
Here is how to overclock the MSI GeForce GTX 1660 SUPER GAMING X video card and our final overclock. We used the latest version MSI Afterburner.
Highest Stable Overclock
We were able to increase the Power Target to only 107% from 100%. Therefore, there isn’t a ton of room on the Power Target to increase, it is very minor. We were also not able to unlock the Core Voltage control at all. We tried every method within MSI Afterburner but it just wasn’t having it. Therefore we cannot try to raise the voltage, which we think would have helped our overclock, but unfortunately, it is completely locked out.
Without changing the voltage, we were able to set the Core Clock up to +130 and the Memory Clock at +800. We also set the fan speed at 100% just to ensure the highest clock speeds and overclock.
We did feel that there was room to push the GPU further if only we could raise the voltage.
GPU Frequency
Here is what that overclock results in. The starting point was actually 2085MHz, but it then quickly dropped to 2070MHz for a couple of minutes, but then it finally settled on 2055MHz after prolonged gaming. Therefore, the consistent, highest stable overclock was 2055MHz on our video card.
At 2055MHz the overclock added 135MHz over the default factory overclock. That’s a pretty big bump, considering the factory overclock was about that much higher over a stock frequency. If you compare 2055MHz to 1785MHz that’s 270MHz higher.
We actually feel that if we were able to raise the voltage, we could sustain 2085MHz, or maybe closer to 2100MHz.
On the memory side of things, at +800 this resulted in a memory frequency of 15.6GHz over the default of 14GHz. That memory overclock brings the memory bandwidth up to 374GB/sec versus 336GB/sec.
GPUz
Above are the GPUz screenshots. The GPU temperature is only 51c at 100% fan speed. This shows the temperature is not holding back the overclock. Power Consumption is up to 139W. We are at the maximum of the TDP, so really it looks like that may be holding us back.
Final Overclock
GPU: 2055MHz
Memory: 15.6GHz
