I went in and applied the patcher, it found all of them except the 640X480. I then went into CRU and added a profile for 75Hz. When I went into my monitor properties I didn't see anything higher than 60Hz. In the Crimson utility, there is an option to set a custom resolution, but the highest it will let me go is 68Hz with a pixel clock of 168.3MHz. Am I doing something wrong here? Should every monitor of the same model overclock the same? I would like to get this up to 75Hz, but so far I am having no luck. Any ideas?

use cru, not custom resolution than it will work.. i managed to reach 77hz on 1920x1080m but trying to figure out with the help of toasty, why my driver is reverting to 16.3 from 16.4.1 after using the patch. besides of that, it works. YOu need also to restart driver after setting the monitor frequence

Are you using the same monitor? I just did it with CRU and if I entered a 75Hz refresh rate, it wouldn't show up in the drop down for my monitor. But if I put in 68Hz, then I can choose that when in display settings. Not sure why I can't get over the hump, could my cable be limiting the refresh rate?

You put 68 with cru or crimson? try also to set no block option in the lower part of cru, and lcd standard or lcd reduced, if you have not tried yet

Got it!!! I set no block and used LCD Standard and am now running at 75Hz, thanks so much!

glad my suggestions helped ^^
