Overclocking your X1800XT
Published: | Source: Overclock3D |Overclocking any X1K isn't very easy, as you will soon find. But, if you follow this guide closely, you will surely have some success.
OC3D will not be held resposible for any issues that may occur as a result of following this guide. Overclocking your X1K card with any 3rd party application VOID's your warranty.
First off, before we start, adequate cooling is a must. Stock coolers will work, but only if you run upwards of 75% fan speed in-game. There arent many 3rd party heatsinks out there either, that work properly with X1K cards. I reccomend removing your stock heatsink, and applying a thermal paste such as Arctic Silver Ceramique, to squeeze some more performance out of it.
Now, let's begin the process. First off, you need to disable ATi's services and startup programs.
To do this, click Start, then click Run.
You will need to un-check two things. Ati HotKey Poller, and ATI Smart.
