How do I 'un' do what has been done.
Well, not sure if what has been done or what I've thought to be done is actually been done to it so I decided here would be the best place to ask for advice on the matter at hand.
My GPU is a right twat if you ask me, does its little crash and recovery crap which I so hate for the past few months, maybe even year. It's called a Nvidia 550ti.
Okay so the question is, about overclocking since it's in that section obviously, I want to know if these settings are right, I don't want to be overclocked as I fear this is what is causing a few of my issues, also heat in the case may be another reason.
But I just want my graphics card to be normal, non-clocked, just as if it was factory bought but non over-clocked factory style.
Either way, you are overclocked and if you have a reference board, that cooler isn't going to keep up with it easily. I'd also recommend making sure you're not running higher voltage, but if you're not stable at all at 970, I imagine you are. My pair of GTX550Ti's are running at 1.150v and run perfect at 1000mhz without issues. However my cards aren't running reference coolers, they are topped with the ASuS Direct CU coolers which perform great.
Either way, you should simply be able to go into the nVidia control panel and set the settings to factory with a simple checkbox.
I would definitely drop the clock using the factory specs which I listed. 970Mhz on 1.100v isn't going to be stable on many of the GTX550Ti cards which you're probably running at. I'm not sure what company made the card, but a stock 70Mhz overclock on a 550Ti is a little much. Mine were factory at 910Mhz but I knew the cooler was good and always have had good luck with GPU's from ASuS.
Just use the custom settings, slap the settings down a bit and you should be good. I'd also suggest if you haven't already, use some compressed air and blow that card out a bit. If it's being unstable with heavy use, then you're probably having a heat issue.
