hi im having a problem with my gpu clock setting in ati overdrive
the current clock setting says gpu clock 300mhz and memory clock at 1126 mhz
but the gpu clock should be at 777mhz
the settings are all on lock but if i unlock and change still stays on 300 mhz

What are your computer specs? This problem may not be caused by the 3870 or software. It may be related more to the motherboard or it's bios settings

Thats actually normal. Download GPU-Z, its a GPU tool that shows temperature and clocks. Here is a direct link: http://www.techpowerup.com/downloads/1031/TechPowerUp_GPU-Z_v0.1.9.html. This app will show you the current clocks and temp.
