i have a question about the memory speed of my 9800 pro 128 mb. it says on the box and on websites that it has a 680mhz memory clock speed, but when i look at radlinker, which comes with the omega drivers, it says that my memory speed is only 340mhz. is this suppose to be doubled or something? radlinker reports the correct core speed though, but the memory speed is confusing me. can anyone clear this up?
