I was not sure about the tearing as i am not having tearing at 60hz but i am having it at 75hz and more noticeable if i cap the fps at 75fps, using like 72hz , 73hz without altering CRU timings has less tearing and thats why i was confused.

Edit: pic with the back of the board , seems that it has the pins for DVI-D DL soldered if i am not wrong:

You shouldn't cap the frame rate to the refresh rate. That's the worst thing you can do for tearing because you'll get a jiggling line. Tearing looks bad when the frame rate is close to the refresh rate. You want the frame rate to be as high as possible away from the refresh rate. If that's not achievable, then at least cap it to something a few frames below the refresh rate. Capping the frame rate to 70 FPS at 75 Hz will look better because the tearing won't be in one spot. The only way to avoid tearing completely is to use vsync, but that will add lag.

Most 60 Hz monitors are hard-coded to reject anything beyond 75-85 Hz. Using a dual-link DVI cable won't change what refresh rates the monitor will accept. The monitor and GPU have no way of knowing if you're using a single-link or dual-link cable. The GPU always sends a single-link signal up to 165 MHz pixel clock and a dual-link signal beyond 165 MHz no matter what cable is being used. The patcher raises that to 230 MHz. If the monitor actually supports dual-link DVI, then you won't need the patcher beyond 165 MHz. If the monitor only supports single-link DVI and the GPU sends a dual-link signal, the monitor will ignore the other link and the resolution will have a blocky look with half the pixels missing unless you use the patcher to send a single-link signal. That 165 MHz switchover is exact by the way, so anything beyond that is a monitor limitation.

Thanks for explanation.
