First you need a tuner.
I use ASUS's GPU Tweak. You can download it HERE
There is also RIVA tuner. Download it HERE
Or MSI Afterburner. Download it HERE
Download one of these and familiarize yourself with them, but dont change any settings yet.
First I would read this whole article to become more familiar with your card and its capabilities. HERE
. It will help you know what to expect out of your card. They also address overclocking in the article.
First you need to get a stress testing program. I use unigine's Valley Benchmark or the Heaven Benchmark. Both are good. Download either of them HERE
Now download GPU-Z HERE
Now get yourself a notepad, or something to take notes with. Open whatever stress program you chose to use. (stick with the same one through the Overclocking process to get consistant results. After OCing is done you can do whatever.)
Also open GPU-z and open the "sensors" tab. Observe the graphs for a bit and familiarize yourself with them.
Also open whichever tuner you chose and record on your notes the settings that are at default. Core speed, memory speed, etc.
At this point you will start the benchmark. (Heaven or Valley from here on out I will refer to it as Valley) Run Valley on stock settings, just whatever it defaults to. The program will load and begin playing a continuous loop of 3D graphics. At this point you should push "F9". It will begin documenting your GPU's performance. Let it run its course until a score card appears on your screen.
Now under where you wrote your default GPU settings record the score you received during the test. Now you know what your card is capable of at stock settings. From here we will be able to gauge if you have a good oc or not.
Now exit Valley. Go to your tuner and bump up the core speed a couple nothces. Ten MHz is a good first bump. Apply the changes. Record the settings in your notes.
Run valley again. Dont forget to press F9. Record your scores for that setting. Better? Worse?
Bump it up another 10MHz. Repeat the benchmark. Record scores? Better? Worse?
Keep doing this a few times. At some point your performance is going to really decrease, the 3D images will get very distorted and not look right, your computer may freeze, or it may even crash down all the way. This is normal. Make note at what setting it crashes or whatever.
Bump your clock back down about 5MHz. Try again. Any Changes? Better score? More crashes?
If more crashes then go back down another 5MHz to your most recent stable setting. Test again and record data.
At some point you are going to find a nice happy medium. Find that sweet spot. Monitor performance, not just MHz. Sometimes more MHz can actually hurt the performance of your card. It does on mine. I had to find the sweet spot.
Now set your core clock back to default.
We will now try and find your memory OC. Bump your memory up by 100MHz. Run Valley and repeat the above steps of testing and recording. Look for changes in performance and visuals.
Keep bumping in 100MHz intervals. Then drop back 50MHz just like the method we just did until you find a nice performing memory overclock.
Now set the core and the memory to the optimal settings you just found. Run Valley and record performance. Better? Worse? Crashes? Freezes? These are all likely.
If so drop the memory down a bit. Then try again. Or maybe drop the core down a bit. (Drop mem before core, core gives more performance) Repeat this until you feel you have the best performing Overclock you can get. Look at scores, not MHz.
I'm sure you'll have questions. Just ask, but mostly just keep trying. It took me quite a while to find my ideal OC. Sorry if I have written this too simple or have insulted your intelligence at all, not my intent. I am just writing this as if you are very new to it all.
Good luck with all your Overclocking!
