I used to have a 6870 and tried some overclocking. I got to about 950 on the core without a voltage increase, but there really isn't any worth in overclocking the 6870, as the performance increase negligible. Look at this:

What software you used to see stability?

I would use Furmark to test for stability, but I don't even recommend overclocking the 6870. You get a big increase in heat and noise with a little increase in performance.
