Nvidia's 'OC Scanner' automatic overclocking feature is now available for Pascal cards

With the release of its RTX 20-series cards in September, Nvidia introduced a one-click overclocking solution that the company said is better tuned for their GPUs, thereby making it more accurate and more reliable.

OC Scanner, which is found in overclocking utilities such as MSI’s Afterburner and EVGA’s Precision X1, runs clock speed tests at a range of voltages to find the exact voltage-frequency curve for your RTX graphics card. The feature stress-tests the GPU and can recover from hangs and crashes if things go wrong.

Now, OC Scanner is available to owners of Pascal-based (GTX 10-series) cards. It’s initially only available in the latest version of MSI’s Afterburner but expect it to arrive in other overclocking tools soon enough.

If you own a Pascal card and want to try out Nvidia’s auto-overclocking feature, you’ll need to download the new beta version of MSI Afterburner (Version 4.6.0 Beta 10). It’s then simply a matter of clicking on the ‘OC’ icon with the magnifying glass in the top left corner and following the instructions.

Being a beta version of Afterburner, you might experience some bugs, but everything seems to be working okay for me. It’s worth remembering that your manual overclock could offer better performance than OC Scanner, but it’s worth giving it a try to find out.

I tried using this on my MSI 1080 Gaming X+ and since then it keeps crashing after a few minutes in games (running the Witcher 3). I used MSI Afterburner 4.6.0 Beta 10 and the oc scanner feature as you explain. I pressed scan and it found me +100MHz with voltage and power unlocked and set to max (so it has room to scan whatever it wants, as the MSI Atferburner official page explains). Since then even after resetting afterburner or setting it to lower settings, it keeps crashing in game. If I set the "silent" preset of "MSI gaming app", I was able to play a hour but it still crashed.

I actually used to have my card set to +125MHz and now it's unstable even with the silent setting... Do you think I might have destroyed my GPU power supplies or something ? I'm not a novice at overclocking but that's something I've not seen before...
Ok so I left my PC unplugged the whole day (just in case it might do something good with the discharged condensers or w/e...), I also moved the power plugs of the 1080 to 2 different power lines on the PC power supply. I Have a 1250W Seasonic modular power supply with 4 power plugs, each of them can be used to get 2 PCIe connectors from it. I had only one of those 4 power plugs used with the 2 connectors of the 1080 on it, so I left that power line unused and used 2 other lines instead, one per connector for the 1080 this time. I'm not 100% if it's the reason but now the problem seems gone. Also it seems that my GPU is slightly less hot than usual, although everything is at the same setting as it was before I used the oc scanner.
