Why not get a working overclock, save the profile, and go from there? You can export your settings to a file that you can say, stick on your desktop. When the card or driver crashes you can at least pull a known good config. Been using that for my 6800, 6800XT, and now 6950XT.
Driver resetting to stock is a safety feature and it does it's job extremely well. It's also not *that* hard to remember four settings..
Foolproof is to run the hardware inside the specs frame. you run it outside. Have you ever heard that tuning a car is the car manufactorers problem? That's your's and keep your's. I don't see your problem. Your config failed and the device drivers switch back to failsafe.
Try actually reading the OP next time.
Step-by-step English-to-English translation of the OP:
0. I apply my OC/UV settings.
1. I use a certain mod.
2. This mod has a bug which crashes the driver in certain scenarios.
3. I reproduce one of these scenarios.
4. The driver crashes.
5. The driver reverts settings to stock values.
6. I don't reapply my OC/UV settings.
7. I relaunch the game.
8. I still use this buggy mod.
9. I reproduce that scenario again.
10. It crashes.
11. I use a different GPU.
12. Long story short, it crashes regardless of what GPU (at least amongst AMD ones) and what settings I use.
So it's definitely not my settings which are to blame. It's not my GPU which is to blame. It's not my buddies' GPUs which I borrowed are to blame. This is the mod, it is the culprit.
Now to the real point of my post.
0. I already know the nature of crashes has absolutely nothing to do with my OC/UV settings.
1. I already got a confirmation from an official mod developer that this is not me who does something wrong.
2. I already found an OC/UV profile which never fails regardless of the game I am playing and absolutely regardless of in-game settings I use.
3. I want to never revert to stock settings, unless I really need to due to comparison reasons or due to degradation causing my OC/UV to stop being stable.
4. AMD don't let me. They revert my settings in spite of the fact my settings have nothing to do with this bug.
5. Ultimately, I am completely annoyed and I really, really want to be able to disable this safety feature because it is completely irrelevant in my particular case.
6. Running some 3rd party software to force my settings or reapplying my settings again, and again, and again is annoying.
7. AMD never commits to actually react to my messages. They didn't even say "No, we won't introduce this." I am okay with a "no," I am not okay with full-on leaving me on read.
Finally, I don't see how I can make it more comprehensible. If you have something to say other than "you are just a jerk and this is a completely appropriate software behaviour," shoot. I expected a couple of messages like that but since more than 2/3rds of orators here are unable to read what I wrote I just wanna give up on this thread.
