So I got the 60.72's installed on my alienware after using a mod'd inf and I went looking thru the options. So I now have the Clock Frequencies tab, which currently shows my settings on Performance (2d) which is 180/360. I then have Performance (3d) which is 275/360. Now, if I click detect optimal frequencies, it runs thru some tests and gives me 342/635. Now, thats a biiig change. What should I set it at? Are any of you using one of these?
