Best way to find stable max overclock for 7950?

Is it just a case of moving GPU and memory clock up in increments (individually) and then running benchmark?

How do I know when it becomes unstable, will the program crash?
 
You will start to see artifacts and then it will crash or you will get lines across the the screen ...it may go red ....you will know when you've reached the max.

Its then a case of increasing the voltage (a very small amount) and trying again ...repeat until your temps are to high, bench test... take screen shots and then turn it down to a decent clock and enjoy playing some games.
 
Not really comfortable with increasing voltages until I know a little more about it.

What would be an expected max overclock for my card using stock voltages (I understand all cards can vary a bit)?

You should quite easily reach 1000MHz on the core, 1350MHz on the memory. Just run Heaven after each bump for a loop or two, and if your temps are okay and you don't see any artifacts/snow then you're good to go. If you crash or hard lock up, then you need to raise voltages or back it off a notch.

As for raising volts, if you're conservative (under 1.2V on the core) then you won't have any real risk if your temps are good (<-- this will be your limiting factor). I ran my 5850 with a balls-to-the-wall overclock for 2 years and it's still going strong.

I will have to check, but I believe my card may run at 1.2v as stock?
 
My pc has been in pieces for a few weeks and I only had my card for a few weeks before my mobo died, so I can't remember what the stock volts are, but I thought they were at 1.1v. I could be totally off though :p
