Thanks for the reply. I tried that and GPU Caps Viewer says that my GPU does not have OpenCL Support. But it should considering its a 4650 which is on the Mining Hardware Comparison wiki

Any ideas?

Im running windows 7 64x, and guiMiner. No extra flags. all that shows up is my CPU

Hey Guys, I want to start mining abit but I cant seem to get my graphics card to work. I have a Saphire Radeon HD4650 and have installed the AMD SDK for OpenCL. I am able to cpu mine, but my gpu doesn't come up as a device in guiMiner.

Sorry, Im kinda new at the whole bitcoin mining thing. I regret not buying a bunch of bitcoins when the price dropped to ~$1 just a few minutes ago
