I am afraid to say, that the native overclocking is pretty much unusable at the moment.

If you have let's say 60x1080ti cards from 10 different manufacturers. You are able to overclock some a bit more than the others. Even within the same model and manufacturers, some cards simply have more silicon or are better made. Thus, if you have cards from multiple manufacturers or different models on the same rig, there's absolutely no way that you can use different overclock settings for each of them.

If you use clocking profile groups, you can NEVER specify a single card, considering that the matching rule options are way too wide. By setting a rule, you are bound to use the settings for cards that you do not want the settings to be used for. Using PCI Id SubDevice as a matching rule would sort this out.

I have 3 rigs, each 12 cards. All of them are 2070 supers from MSI. Still, some can be pushed more than the others. There's literally no way that I can overclock each card on each rig separately and make the settings stick after the reboot.

I also do not understand the necessity of using overclocking profiles. Sure, it's a nice feature to have, but why there simply isn't an option to just overclock the rig, each card however you want, save it, check an option to apply everytime the miner starts and be done with it.

Instead you have to overclock it, save profile and then apply profile in different menu. This way it takes much more time, complicates everything and after a few months you are stuck with hundreds of overclocking profiles and it's simply a mess. And even that profile doesn't apply to the entire rig, merely to 1 card.

I really don't get it.
