I just bought an XFX 8800 GT and I have some questions on it. I am using RivaTuner and it is reporting my Core clock as 670 MHz, which is right. It is reporting my Shader Clock as 1650 MHz, which I am not sure if it is right or not. Then it is reporting my Memory Clock as 975 MHz. Why is that? My memory clock is supposed to be 1950 MHz. This is my card http://www.newegg.com/Product/Product.aspx?Item=N82E16814150254 PLZ HELP!!!
