Is my GPU's Overclock unstable?

As you guys have probably already guessed from the massive amounts of posts I've made in the past day I'm OC'ing my GTX 480. Currently I have it at 840 Core, 1680 Shader, and 1935 Memory. I have no idea what the voltages are as EVGA precision does not display those. Anyway I've been playing a free mmo called Vindictus to test my GPU, it doesn't gone past 80 C, heck even upper 70s is rare, the FPS is above 60, and the fan speed hasn't broken 65% yet. This is all with highest graphics setting and AA x8 + Antistopic Texture x16 + 1650 x 1080 res (my monitors max). I ran Vindictus with windows experience index in the background and the results were quite pleasing as even at 90%-100% GPU usage my temps, fan speed, and fps were still in the ranges mentioned above. I also ran Metro 2033 with the same settings and got almost the same results, my fps was in the 40s.

Later I downloaded OCCT and it found over 1500 errors in just 5 minutes. Note that I did not see any artifacts while gaming and I have not had a game freeze up on me (except when my internet connection was super weak). But OCCT did make my card hit 90 C, as well.

So should I be worried?
 
If it works fine in games, why worry? Even if you are getting artifacting in games, you don't notice it, and it isn't going to affect the game itself, so I wouldn't be too concerned. If it starts crashing, different story.

No crashes yet. It only crashed when I put the core at 950, hence why I don't have it clocked higher. Btw on an unrelated note when my card crashed everything just went back to normal a few seconds later, what if it didn't how do I get it back to normal if it doesn't recover automatically from a crash.

As you can probably tell I'm still in the dark ages of overclocking.
 
Normally it would just take a reboot if it hard locks, then you can turn down the overclock.
 
Ah ok, thx. Btw should I find a way to edit voltages too, would that let me hit 950 core and 2050 Memory because it crashes if I set either of those 2 at those levels. Does EVGA Precision automatically do my voltages since it doesn't even give me the option to edit them?
 
I think I used Afterburner when I was overclocking my 480, I'm not sure if Precision supports voltage control for those cards or not. You do have to change a setting somewhere to allow voltage control (at least in Afterburner).
 
Would voltage control, theoretically, get me past that 940 Core and 2050 Memory barrier or am I still gonna get crashes?
 
In theory, more voltage should give you more overclock, but at some point you will hit a wall. No way to know if you are at that point without trying though. I say if you are curious, give it a shot - you aren't going to do any permanent damage from testing it.
