I'm not responsible for your mistakes. If something goes wrong, it's your fault, and by using this tutorial, you totally agree with that.
1) Get
Riva Tuner,
GPU-Z, and
FurMark.
2) Install everything. (Note: GPU-Z does not get installed, you simply double-click the downloaded Executable file to run the program)
3) Open up
GPU-Z and
Notepad. Take note of the "
GPU Clock", "
Memory", and the "
Shader". This is your "Before" of the "Before and After", so that you can compare what you had before you overclocked.
Picture. (Note: The sections you took notes of should match their corresponding default settings exactly. Mine do not because I have already overclocked my video card)
4) Now, you can minimize Notepad, but keep GPU-Z open in an area that you can monitor the sections that you took note of in Step 3. Open up FurMark and Riva Tuner. (Note: If Riva Tuner says something about you using an "unsupported driver", ignore it)
5) In
Riva Tuner, you'll get something that looks like
THIS. Click on the little triangle under the "
Driver settings" section (
Picture) and then select "System settings" (
Picture).
6) After that, you will have a window that looks like
this. Make sure that the checkbox next to "
Enable driver-level hardware overclocking"
is ticked (
Note: When you do this, it will ask you to reboot the computer. Instead of Rebooting,
hit the "Detect Now" button), make sure that the checkbox next to "
Link clocks" is
NOT TICKED, and that the drop-down box next to it has "performance 3D" selected.
7) In the
FurMark window, basically just make it look like
this picture.
8 ) After that, hit the big "
Go!" button on the
FurMark window to start the Furmark thing. You will probably have a VERY low FPS (Probably less than 15 FPS)
9) On your
Riva Tuner window (The one with all the slider-bars), slide the "
Core clock" slider to the right until the number increases by 10-15. Hit
Apply.
Wait about 30 seconds (IMPORTANT! DO NOT GO TOO FAST. THIS IS A SOMEWHAT TIME-CONSUMING ACTIVITY!! BE PATIENT!). If at any time during that thirty-seconds you saw
oddly-colored dots appearing randomly all over the FurMark window, you need to
move the "
Core Clock"
slider backwards slightly until you find the very last safe number. If the FurMark window crashes, you need to close everything and restart your computer. Continue doing this until you find the very last safe number. Take note of this number in your Notepad, then (THIS PART IS VERY IMPORTANT) hit the "Defaults" button at the bottom of the Riva Tuner window.
10) Do the same thing with the "Shader Clock" slider. If you move too far, you will see triangle-shaped black objects flashing all over the FurMark window. You will know them when you see them. You need to move the slider back slightly and find the last safe number. Take note of this number, then (THIS PART IS VERY IMPORTANT) hit the "Defaults" button at the bottom of the Riva Tuner window.
11) Do the same thing for the "Memory Clock" slider. If you move too far, you will see rectangular black objects flashing all over the Furmark Window. Take note of the last safe number when you find it, then (THIS PART IS VERY IMPORTANT) hit the "Defaults" button at the bottom of the Riva Tuner window.
12) Once you have all of your final safe numbers written down, hit the button on the button of the Riva Tuner window that says "Defaults". After that, move all of your sliders one by one to their respective maximum safe number. Then hit apply. You will likely see artifacts (The black shapes that flash all over the place). If this happens, you will know which slider to adjust because of the shape of the artifacts (Convenient!).
Once you are happy with your settings, Tick the checkbox next to "Apply overclocking at Windows startup" to make sure that these settings stay constant.
Hit Apply, and OK, then close everything and restart your computer. You have successfully (I hope) overclocked your Video Card!
Feel free to post a comparison of the numbers you started out with and what you ended with in this thread!
