To test the overclock of a mining card do you just increase the clocks and run GUIMiner (or other mining app) until it crashes, and then reduce the clock frequency or increase voltage?

when u find the cards Mhz ceiling then raising the voltage can raise the "ceiling" tho you want to think real hard b4 raising the stock voltages.... its the one thing that "could" damage your card plus it can seriously raise the number of watts your card draws....

remember with raising the voltage its all about doing so in very, very small increments say .005

for my 5850s, increasing 0.01v = additional 30w pulled from the wall.
don't increase it too much. it'll be less cost-efficient.

You may even consider lowering the voltage.

Some cards net more money stock clocks and undervolted, some net more money overclocked and stock voltage, etc...
