Hey!

im pretty new to overclocking and all that stuff because i've never done something like that until my 144hz monitor just broke. I want to overclock my Samsung C27F396F (60hz, FHD) Monitor as much as i can so i can use it like that until i get a 144hz+ monitor.

But the problem is when i try to Overclock over the Nvidia Settings, the screen goes black at 75hz and it says "Not Optimum mode, recommended mode 1920x1080 60hz". I wanted to ask if that is more like a warning or if that means that its the highest hz i can get?

That's a firmware lock. Usually that means that indeed the monitor won't let you use higher Hz. My Samsung FHD monitor allowed up to 77Hz with "native LCD" timings in CRU. Higher Hz would result in that message. For nvidia cards I had to use the pixel clock patcher though:

Otherwise the graphics card itself wasn't able to output more than 66Hz with "native LCD" CRU timings.
