Other than that using Unigine Sanctuary at 1024x768 Full Screen, 3DMark06 and Vantage will show how the card responds to the autotune from CCC.
autotune freezes my computer after awhile.
That may be due to your drivers version, I have had good luck with CCC 10.3 and am testing CCC 10.6 in the next couple of days did not care for 10.4 and 10.5
I have driver version 10.6. It froze for me when I had 10.5 45 minutes into autotuning

Should I continue increasing my memory clock (Can't increase gpu clock any further) and/or increase my voltage with msi afterburner as smarteyeball suggested?
If you are happy with current speeds - then increasing the memory doesn't have as much impact as increasing the core itself.

Keep in mind that extra volts = extra heat and there is still no guarantee that you will 'break the barrier'. Each chip has a wall, regardless of voltage

Also is it good to test custom clock speed in CCC?
Personally, I've never bothered with it.

That's one of the reasons I don't use autotune. Clocks too high - insufficient voltage/wall = freeze.
