All things done with the knowledge gained from this file are your responsibility and no-one else can be held liable for any damage done. Step One: Get The Latest Driver. All nVidia GPUs use the same driver which is known as the ForceWare driver. At the time of writing, the latest version was ForceWare Release 60. So, head to www.nvidia.com and download this. This alone will increase the performance of your graphics card. Also make sure you have DirectX 9 installed which can be downloaded from www.microsoft.com, install this before the driver to ensure no future problems. Step Two: Make The Necessary Changes To The Registry. To over-clock your card you will need to make some changes to the registry, so press windows-R to open up 'run' and type in regedit to open up the registry editor. Navigate to HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\NVTweak. Right-click and select new|DWORD value. Name it 'CoolBits'. Then, right click on the value you just made and select 'Modify'. Make sure the base is set to hexadecimal and make the value 3. Now, reset your machine. Step Three: Pre-Over-Clocking Changes. On your desktop, right click and select 'Properties'. Click the 'Settings' Tab, then the 'Advanced' button. There will be a tab up the top with your graphics card's name one it. Click that. You will notice that there is a menu thing popping out of the left hand side of the window (if its not there, click on the 'Additional Properties' button). Click on the 'Performance and Quality Settings' heading. Make sure the 'Show Advanced Settings' check box is checked and scroll to the 'Vertical Sync' option. Click on this, un-check the 'Application Controlled' check box and select 'Off'. Step Four: Over-Clocking Your Graphics Card. Before you begin anything, head to www.madonion.com and download 3DMark2001SE. Head to the same place you were in step three but instead of selecting 'Performance and Quality Settings' select 'Clock Frequencies'. Click on the 'Manual Over-clocking' radio button. Read the disclaimer and accept or decline depending on what you think (keep in mind that you can't over-clock your graphics card without accepting). The first thing you should do is make a table on some piece of paper you have lying around. There should be 3 columns named CCF, MCF and 3dMark respectively. Copy down your current settings into the first row in your first to columns, close all un-essential programs (this includes any open network/Internet connections) and run 3DMark 2001SE (we close everything to give the most accurate data). Copy down your score in your table and head back to your clock frequency settings. Now bump up your CCF by, lets say, 5 MhZ, click test changes, if nothing weird happens while its doing this, click 'Apply' then 'OK'. Now run 3DMark2001SE again and see the difference. Now just play around with the settings moving them up and down to find your graphics cards sweet spot. If you start getting glitches or the 3DMark Drops, it may mean you are trying to push your card too far – drop its speed by 1 MhZ at a time until you find that sweet spot. After you have found this sweet spot, check the 'Apply these settings on startup' check-box, accept everything, and reset your computer. Now go and play some games and notice the difference!!!
