Hi, I managed to successfully convert my HD6950 to HD6970, however, I observed a slight decrease on my 3D mark 06. Before converting, it was 16897, after converting it became 16562. Though I would like to add that there's an increase in score for 3D mark 11 (from P4138 to P4387). I've increase the voltage by 20% from ati CCC and the clock is currently at 880mhz memory clock is 1375mhz. I've checked gpu-z and obtain the same result as the guide. Now, is there any reason why there's a decrease in score instead of an increase? Next, I would like to ask what can I do to test to see if there's rendering errors? Thanks in advance. Edit: I forget to mention that this message appears when I get the result from 3D mark. "Your result has the following problem(s) and will not be shown for example on leaderboards: Graphics driver is not approved" Will this cause any problem?
