Sounds like one is messed up alright -- I mean, there is a reason the chip becomes the NU typically, so not everyone can unlock. Well, you MIGHT be able to open just one. Try opening one at a time and see what happens. When you get weird stuff like the blue lines, go back and close the one you just opened. Typically people at least get the vertex shader open, which doesn't help much, but, it sure won't hurt anything.
And jcy0001, yours is a bit on the weird side I'll admit. Basically all I can say is to try running things like rthdribl for long periods of time and see if you notice any artifacts. Set all the options you can as high as they go and raise the size of the window. You want to force it to push your card about as hard as it can. Also, run Doom 3. I noticed no artifacts in 3DMark05 when I ran my GPU at 450 when I had 1.4V for testing, but, in Doom 3 it would crash and artifact until I stepped down to 425. And yes, raising the clock rates heats up the card more -- to a certain extent. I think the rule of thumb is to keep it from going past the upper 70C range on the GPU, but, someone else can feel free to jump in here and correct this. LeadTeks seem to all run cool, and I've never even hit the 60C range, so I never really worried much about temperatures on mine. Anyway, as with all overclocking, there is a slight risk that you can be pushing things too hard and do damage in the long run. It's up to you if you care to risk it. That said, typically just overclocking alone won't tear things up so long as you keep them running cool enough. That's the key. Don't let it get too hot. Oh, and to test for stability, just play games like Doom 3, Far Cry, etc. If it starts artifacting or your system locks up or crashes when it never did before, it's unstable. Lol, that simple. So far as I know, there is no Prime95 style thing for video cards.
Oh, Soverign. Ah... Lol, that shouldn't happen. Oh well, if you get no artifacts, you get no artifacts. Just, be careful, if you got the lines once, there may still be something unstable somewhere.
