As title I'm interested in how you guys know all is good. With folding gpu it would just fail if I went too high but this??
I only have 2 cards with voltage control if that is important...the others seem to have that blanked out in overdrive

From what I have seen with my own cards. The 6950 has voltage control while my 5850 does not. Either card acts the same. If the clocks are unstable the system will lock up. Some times if your lucky the display driver will just crash and you can try again. Also you may notice that your MHash/s will be more stable less fluctuation. The best my 5850 will do is 820 on the core. The 6950 will do 910 @ 1.212v.
My 6950 is also my daily use system. I have only ran into a few websites that I have to stop mining if I want to view them. Other wise the system locks up.

I noticed that the display drivers fail and restart when not stable. So I just backed down to a comfortable level
Also concerning overclocking.. I think temperature correlates with reject rates. I don't know though if this is memory or core related.
I see nobody has mentioned stale/fail rates..... anyone noticed a connection?

By upping the voltage on a gtx465, I was able to reduce the stale/fail rates from 10% at 750mhz to 1% at 820mhz. Same temps and memory speed (with a higher fan speed of course).
