That's no problem, as long as they are stable :). But i think you are wrong: in the dmesg output the card is set to 930 Mhz (if i read it correctly). And the stock 6870 uses 900Mhz. Maybe the voltage is not adjusted correctly? Whats the effect of an undervolted card?
Yes, but if I remember correctly again, the real values are not printed out in kernel <= 3.13 if they were limited. I think I've seen a patch from Alex or Christian about that so we can have the real values in kernel 3.14.
Otherwise, I could provide you a patch of mine that gives the real values used (it's printed as a warning saying the values have been limited to X). I'm experiencing similar problems with my HD6950, that's why I've been digging on my side.
