I run 3 monitors and my GPU just died yesterday.  It's a Zotac GT640 (cheap one.  I'm not a gamer).  I found a video card with comparable specs for $105 which is about what i paid for my old one 3 years ago.  However, my one concern is that the new card is "superclocked" from the factory.  As i said, i'm not a gamer and i'm very wary about overclocking as i've heard that can have disastrous results if done wrong. 

 

After i get this new card, how would i go about removing the overclocking and bringing the card back to factory specs?  I don't need the overclocking and i'd rather be safe.  I've never done this before and know virtually nothing about it.  Can anyone give me a brief tutorial on how to find out what the clock speed should be normally and how to reset it?

Because it's a factory overclock (generally perfectly safe BTW) which will be hard coded into the cards firmware, AFAIK you would have to use overclocking software to underclock the GPU.  MSI Afterburner is a popular choice (card doesn't need to be MSI made).  Link goes to MSI page which includes tutorials and guide.

 

Reference clock speeds of GPU's can be found in the database here - http://www.techpowerup.com/gpudb/

Thanks.  I do realize that since it's a factory overclock, it probably is perfectly safe but i'm the kind of guy that likes to cover his butt five ways from Sunday so i figure why take any chance if i don't have to.

The factory overclock ones usually come with beefed up coolers to deal with the main enemy, heat.  But might it not be better to find one that isn't factory overclocked instead?  Guessing from the price you're looking at the GTX750 range, maybe something like this - http://pcpartpicker.com/part/pny-video-card-vcggtx750t2xpb

Yeah, but i needed one right away and this one was in stock with the connections i needed and the specs were close to my old card so i grabbed it. I can't imagine a decent card being much less than $100 anyway.
