OC monitor stuck on YCbCr422 and wont go to RGB

[Phaedom]

Hello, so I've managed to OC my monitor from 144hz to 162 successfully with no frame skipping and with Gsync stretched with it as well (48-162) at 1080p but I run into issue where the output color is stuck to only YCbCr422 and isn't giving me the option to switch to RGB. I used the exact same timings as Nvidia control panel for the overclock to make sure there wasn't any issues. If you also do it through Nvida control panel it it keeps it RGB but drops the output color depth from 8 to 6 (Same thing for the OC through CRU but with out RGB setting). Im assuming this has some thing to do with the bandwidth or the timings I used considering a forum post in the past...I know my cable isn't the problem since its DP 1.4 and its not my GPU as its a rtx 2070 super. I also tried the presets for the timings and it wont work unless its the reduced preset but even then its buggy sometimes so Im stuck with this. Is there any way to fix this while also maintaining hopefully everything from 144hz? Thanks in advance!
