Custom Resolution Utility (CRU)

[ViRuS2k]

need your help toasty as im stuck....
--------------------------------------------------
Monitor : AOC 29" 2560x1080p @60hz.... 21:9 Aspect : LG Panel.
--------------------------------------------------
Connection : crossfire 7900 series cards ~ mini displayport to displayport cable.
--------------------------------------------------

Theoretically i should have no pixel limits but for some reason i do.

Resolutions that work so far :

2560x1080 native resolution @*72hz (*judder free 24hz bluray playback) or 75hz or 76hz or 85hz
2560x1440 works @60hz (Aspect ratio is out looks stretched
2560x1600 works @60hz (Aspect ratio is out looks more stretched
3000x1440 works @60hz (Aspect ratio is out looks nearly right
3440x1440 works @60hz (Aspect ratio correct 21:9 Perfect) (Even though the quality is great, could do with making the text more sharp.)

All of the above work without any issues and without driver patched as displayport does not need it though i might be wrong as for some reason i am hitting a pixel clock limit for some reason.

im trying to get 100-120hz working @ native
i can get 100hz working perfectly with a pixel clock :300.25mhz
now when i try to go for 120hz i can only seem to get 109hz locked with a pixel clock at :327.00mhz this is where im stuck i can not for the life of me get over 327mhz im stuck and for 120hz i need over 370+mhz why am i stuck here
i figure its pixel limit as when i try to add the resolution i get a adl display_mode timing override failed using the downsampling GPU....
also the other issue is listed above is there any way to make the text ultra sharp or more sharp than it already is, i have tried cleartype on and off ...... i wonder why im hitting a limit though :/
