I have the XFX Double D 7870 and 12.10 drivers. I currently have it at 1150 on the core and 1400 on the memory and no voltage increase, but it seems if I increase either one my games crash much more often.
Are the 12.11 drivers any good?

So what's a stable overclock?

You can test with furmark to see whether the OC is stable or not
