Hello Forum. I require your assistance on overclocking my ATI Mobility Radeon HD 4200 I have tried several programs such as MSI After Buner, and AMD OverDrive But they don't allow me to change the settings. The sliders are locked. Surely there must be a way. The reason I wish to overclock is I want to run shadows in MW3. Right now it's a little laggy, but It wouldn't need much. I'm wishing to stay in a safe limit. Any help is greatly appreciated. I'm very new to the subject of overclocking.
