Overclocking, techniques for increasing your computer's performance

 

 


 

Overclocking graphic cards


Graphic cards contain a principal processor whose internal clock is “easily” programmable by accessing the SVGA registers regardless of the speed of the motherboard.

However, this “only” accessing the registers is fairly difficult for 95% of PC users, although luckily there is a utility to solve it: MCLK. This small program, allows you to modify the clock of certain video cards (mainly S3 and Cirrus), providing performance improvements of up to 20%.

To increase the clock on more recent cards such as the nVIDIA range, you need to use the 3.x version of the detonators and enter the following information in the register for Windows9x-ME:

REGEDIT4

[HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\NVTweak]

"CoolBits"=dword:00000003

Windows 2000:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\NVIDIA Corporation\Global\NVTweak\DISPLAY1]

"CoolBits"=dword:00000003

AGP Bus 

The speed of the AGP bus is also obtained through a divider controlled normally by a jumper on the board, whose positions are 1/1 and 2/3 (two-thirds) of the frequency speed of the motherboard. This way, if you modify the frequency of the motherboard to 75 Mhz, setting the jumper in the 1/1 position, you will increase the speed of the AGP bus by 9 Mhz (originally set at 66 Mhz).
