I didn't try to undervolt but I can find your spot......

oh wow.

Cool.

That's interesting.

So these spot's are more universal than I thought.

With the 7970, or the R9?
The exact same CC:854 MC:799 ?
How many khash?

Now that you found my sweet spot on your card, I am starting to ask the same question...:

don't know why you can't find mine.....

Yes, now I agree, that that is odd.

Hypotheses:

* Perhaps that 7970-optimum is actually slightly off your CC:925 MC:990 ?
Did you optimize in 5Mhz steps, or in the end like this ... 927 ... 926 ... 923 ... 924 ... 925 ... ?
If not, could you try that for me?

* Your cards are "used to" high performance. Perhaps there is a history dependence? Mine is only 3 weeks old.

What to do?
