Hi! I have this graphic card and while it's a little bit old, there are a lot of games I can run smoothly in medium/high graphics. I don't care too much about the graphics resolution, but I can't stand low framerate. So I decided that I want to overclock my graphic card, but I have no knowledge about that and I don't even know if overcloking this graphic card could do any good.

So maybe someone could help me do it or at least tell me how to do it and if it's worth the time?

You won't really see that much of a difference overclocking this card.. But if you want to overclock it here you go:

-First you need MSI afterburner and Furmark (google them)
-Start MSI afterburner(Some sliders may be locked, if they are you can't overclock)...

You won't really see that much of a difference overclocking this card.. But if you want to overclock it here you go:

-First you need MSI afterburner and Furmark (google them)
-Start MSI afterburner(Some sliders may be locked, if they are you can't overclock)
-Set fan speed to 70%(or more, you decide)
-Start Furmark and start it windowed
-Overclocking time

Starting with the memory, shift the slider to the right in small, 5-10MHz increments. This will allow you to hopefully see initial instabilities in the VRAM before you fully crash the machine. Moving up slowly like this will give you the best chance of avoiding frying your card too. After every 10MHz step carefully check the furmark window for artifacts. You’ll know when your memory is starting to fail as you’ll notice large blocks of solid colors or stars appear on-screen. Now you can start overclocking the GPU itself. You’re unlikely to be able to get as much extra speed out of the GPU as you were able to with the memory, but you’re also likely to get a bigger performance boost from tweaking the actual chip than the VRAM. Follow the exact same method with the GPU slider as with the memory. Move upwards in small increments until you start to see some instability in the Furmark window. This time, though, you are looking for different artifacts in the benchmark display. Instead of stars or blocks of colour you need to keep an eye out for random, multi-colored pixel-sized dots around the screen. GPU instability might also appear in the form of coloured flashes on-screen. These are the sure signs that your graphics chip is suffering.Once you’ve found the limits of both your chip and the video memory attached to it you can combine the two clockspeeds. In your overclocking application push the GPU and memory clock sliders up to your discovered maximums, hit apply and check your Furmark window. Next step is to do a stress test. Hit burn-in test in furmark and let it run for about an half of hour. If your GPU crashes you will need to review all of your clocks and decrease them until it's stable. Last step is to do a fan curve if you wisg in MSI afterburner (google it). I personnaly prefer to set the fan to a fixed speed (70% for example.)

Enjoy your overclocking.
