Yes and I find nvidia cards degrade and become unstable with that auto overclocking, which you don't seem to be able to disable :/
Similar with auto CPU overclocks, they will often use way to much voltage.
You can enable k-boost, even with Pascal cards - though the odd model seems to lack firmware support for it - then set whatever clock - on Pascal you might still see throttling type behaviour from higher clocks if you are trying to use it to hold a maxed overclock but that isn't an issue if your intention is to hold back the clocks.



It's a shame AMD isn't in a stronger position, If they were Nvidia wouldn't think twice about supporting it.
