NVIDIA's Titanium series of graphics cards have been a hot topic since they were launched earlier this month. We already answered the performance side of these boards in our GeForce3 Ti 500 and GeForce3 Ti 200/GeForce2 Ti previews, but today we wanted to address the performance of these boards when they're pushed to their max. That's right folks, today we take a stab at overclocking our precious Titanium boards, and as we expected, the GeForce3 Ti 200 becomes an even more attractive product once its overclocked. But how did we overclock our Titanium boards you ask? Simple, with a small modification to the Windows registry, overclocking any NVIDIA-based product is a snap (assuming you're using the reference drivers available on NVIDIA's website). 

Simply open the Windows Registry Editor by typing "regedit" in the Run Menu of Windows. Then open the following directory: "HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global" Right click on the "Global" directory and create a new key titled "NVTweak." Next, right-click on the NVTweak key and create a new dword value named "Coolbits." Adjust the value of Coolbits to "3" by double clicking on it and entering "3" in the value data field. 

After a quick Windows restart go to the "Additional Properties" section of your display settings. Click on the "Clock Frequencies" tab and checkmark the "Allow clock frequency adjustments" setting. After that, you're ready to begin overclocking your card!
