Overclocking is a method of enhancing performance of a computer component by pushing its clock rate over manufacturer recommended settings. In the case of graphics cards, such as the Asus AH3450, overclocking can increase the frame rate of video games. The Asus AH3450 is a variation of the Radeon HD 3450 graphics card manufactured by ATI and can be edited using the same software as other ATI graphics cards. There are several downloadable programs available to push the card's clock rate over that set by the manufacturer.

Open "ATI Catalyst Control Center." This is a standard program installed to manage your Asus AH3450 graphics card. Included in the program is a menu called "Overdrive." Adjust the rating in this section to boost the clock rate of the graphics card. However, the program places a limit on how much the card may be overclocked.
Download "ATITool." ATITool is a graphics card utility compatible with both ATI and Nvidia graphics cards. Click on "Find Max Core" and "Find Max Mem" to see the maximum settings of your graphics card. Use the adjustable levels to overclock core and memory settings of your card.
Note: ATITool only works for Windows 2000, XP and 2003 (both 32 and 64-bit versions). Vista is only partially supported. Windows 7 is thus far not supported.
Download "PowerStrip 3.7." PowerStrip is another freeware alternative to both ATI CCC and ATITools that supports all Windows systems from 95 up to Vista (including 64-bit versions). Disable your ATI CCC Overdrive before using PowerStrip. Adjust the level slider to increase the core and memory of your graphics card.
Tips and warnings
- Overclocking your graphics card increases power consumption and heat generation. Overclocked systems must be closely monitored to keep them from overheating and burning out. Adjusting your computer components too far beyond manufacturer-recommended settings can cause irreparable harm to those components.
