Stepper motor locks up when going higher than 8mm/s

Hello everyone. I'm having a problem with my stepper motor,it appears to lock up on speeds higher than 8mm/s. It's only my Y axis motor that does this,my Z axis uses the same motor and stepper drivers and it works fine. In the video I hooked up another motor to the Y axis cable to show that the problem isn't mechanical. I've reinstalled Marlin and checked the wiring. I've replaced the stepper motor,cables and the driver. Nothing changes. I have even tried switching Y and X outputs on the RAMPS board from the original code and the problem still appears on the Y ,even if it has switched places the problem follows it. What could be causing this issue? It's running at 1/16 step. My 3D printer is limited to 8 mm/s printing because of this which is really really slow.
