To see if it is stable, test it out. Play games and see if it crashes, if not, then its stable.
When I click on After Burner the Core Clock and the Memory Clock both are at 0MHz. I looked up my GPU where I bought it from and it said my core clock was 915 MHz GPU and my Effective Memory Clock 6008MHz. Is that what you mean? Or do you mean start by putting the Memory Clock higher?

I havent usee afterbuner just percison but you click on the slider and mover it up alittle or click and use arrow keys. Try 50 mhz then play youll know when it wont take it. I have to hard shut off mine because it freezes. Been playing around with my old 560 ti and cant get past 970 mhz darnit.I think its because I did a mod on it awhile ago then restored back to stock but the thermal pads were bad so I usee paste instead. Couldent get any pads here. Anyways yea just play around with it thats how youll learn. You wont kill it just dont go all crazy on the numbers. Maybe download a program to monitor frams per second like fraps or something so you can see the results. You know test stock then test overclock thats what this community does.

A GPU is probably the easiest component to overclock, and especially with a 670 it's almost impossible to break it. worst case scenario it's a little unstable, you won't do any permanent damage without some more in depth modification.

The 670 master guide is good, you want to increase core clock and memory independently. Once you have good clocks for both, you can put them together. Leave voltage alone, but you can go ahead and max power target.

What would be a safe temperature and what would be bad? Is 80 a little too much?

Adding 100MHz memory would mean 6108MHz memory. 500Mhz added = 6508MHz memory

So I should start off adding 100MHz to the Memory Clock? If so how much should I ad to the Core Clock. And what should I do about the Power Limit? What the Power Limit for?

Ok, set the power limit to the maximum. Doing so will allow the card to use more power if it NEEDS it.

Pick a number on the memory, say 500+ Mhz. Then play a game for about 30 minutes, does it crash? If not, you know that your card can handle at least 500MHz memory.

Do the same for the Core clock, except, 500 would surely crash it. Instead start of by 100+ then increase by 10Mhz until it crashes.

It is very very simple!

Keep an eye on temps. No more than 80C Spin those fans up if it gets hot
