- Drop sense pin usage.
Why?
Some mainboards don't implement sense pin properly and have other signals connected to that pin. This can lead to invalid output voltage reading. In the worst case sense could be bound to ground, which would report 0V to the controller all the time, which would try to ramp up the voltage to the maximum of about 4.4V. This could potentially kill the CPU, especially low voltage K6-II or similar.
Due to this issue, the feedback voltage is now read directly at the vcore output. This could potentially lead to slightly lower output voltage at the CPU, since we would not read the sense from there, but it is much safer and would work on more mainboards.
