That's a CRT monitor. You're not using single-link DVI with a CRT monitor. That monitor doesn't even have DVI. Even if you're using adapters, it's still just a VGA signal, so I don't know why you need the patch.

So, I had installed the patcher for the single-link bottleneck for my old monitor. I think this may be the issue that my monitor is experiencing because it can't run at 144Hz like it was designed to. No option comes up in Nvidia CP or Windows regarding 144Hz. It's just 60Hz and 59Hz.

It's definitely the cable that's wrong. 2560x1440 @ 144 Hz will only work out of the box with DisplayPort. 2560x1440 @ 120+ Hz is not going to work out of the box with DVI because of the 330 MHz pixel clock limit. That's why the patch exists in the first place.

2560x1440 @ 120 Hz might be possible with a custom resolution if the monitor will accept it over DVI. I don't know if your video card can handle 2560x1440 @ 144 Hz with DVI, but it might be possible by reducing the timing parameters.

It's in the main post:
