lol why didnt i think off the big padlock thanks, but surely the auto tune tool should be safe enough as its built in and i done this once with my old Nvidia 9500GT and that OC fine with no probs just can only go up a little bit but auto tune i though was a good idea as it knows itself.

You are better off doing it manually.

Auto tune may or may not have improved since the last time I tested it - but when I did last test it, it set the clocks to ridiculously unstable levels.

Use it at your own peril.

Start off pretty slow (10-20mhz) bumps for both the GPU clock and the memory clock. Keep increasing until the temps become too much, or the card starts to artifact / misbehave.

ATI overdrive doesn't adjust voltages so there will be a wall it will hit with 'stock' voltages.

For stress testing, you can either use the tried and true Furmark or the newer kombuster that is part of MSI AfterBurner

*NB You have to install install kombuster separately to MSI AB.

Leave adjusting the voltages alone for now and find the 'wall' with stock volts first. And yes, it can make a difference depending on the amount of overclock.

Watch your temps when stressing the card - don't run them for too long either (5-10mins) as they will place a very heavy load on your card. Stop the tests immediately if you notice the temps are too high, or the card starts to artifact.

(Artifacts are little graphical glitches/dots)

its safe. Im OC'd from 650 to 700mhz right now with it. It doesn't seem like a lot but it helps in some areas.

Run Furmark stability test. It will run that thing hotter than hell. After so much your cards fan should kick up and cool it down. Use it to see what it can take. Or you can use it to see how well a manual fan speed handles. I used it to find out if my 65% manual speed was good. It wouldn't let it rise higher than 63c.

it's actually ridiculously stable now, but it's still better to let it autotune, to give you an idea of how far to go, and use furmark to stress test
