GPU overclocking history?

[phantomasko]

Hey guys, I don't know who should I talk to with this, but I have this problem on my mind that is starting to worry me.

So I have a couple months old Asus HD7970-DC2 TOP. After I've built my PC and installed utilities, I loaded a default overclocking profile with either MSI Afterburner or ASUS GPU Tweak tool that messed up my clocks and I may have runned OC for awhile. This is my first build ever and I wasn't that experienced with PCs until now, so keeping that in mind my question is...

I noticed on one of the livestreams Linus said something about how overclocking is good because of the extra power, as you can get around warranty issues with a couple of "clicks" (if your card dies), which he didn't want to specify because of obvious reasons. So I'm sure there is cache or some other place where the card stores these things, and I want to clean that. What's the process of cleaning your cards OC history? I'm worried as my card has been acting strangely from the start with artifacts - in games and in windows too. Not so much but every now and then. Temps good as are the sound levels, so I'm quite satisfied with the card, hence why I don't want it to die. Don't want to overclock any further from 1GHz until I know how to safely.

Want my warranty to last, could someone help please?

I don't know how the warrenty rules are where you live (That is good thing to write down, when asking stuff like this), but where I live overclocking is considered a "feature" of a product. This means that if I buy a graphicscard or a unlocked CPU, the store where i bought it has to offer me a return if it breaks (This is within limit of course. I can't run LN2 and then expect a return).

The question I have for you is: Have you overvolted the card in any way? Also I have never heard abour companys checking if cards or CPU's have been overclocked unless there was physical damage to the product.

I'm pretty sure the overclocking info is on your storage drive.

I've never heard of overclocking info being stored on the card.

And those 'clicks' linus was talking about was putting the clock speeds from your overclock back to default so when they recive the card plug it in they don't see overclocked settings they see default settings.

Well a friend of mine that helped me with PC parts had following experience.

When he tried to return a CPU that broke, they didn't take it because he used different thermal compund than Intel's (note: with stock cooler).

He said they look at the cards clocks and that I shouldn't try it because cards don't have protection like CPUs do.

The card does have upped voltage by default, I haven't moved it. I did set +20 power limit though.

Can't get more specific as I'm away from PC.
