Separating CPU and GPU

[Quickstart3700]

Hello everyone, I was looking at the zenloc custom regulator page and saw that it is possible to power the CPU and GPU separately in order to make the power draw more efficient. However, where would I attach the 1.5v and 1.7v for the CPU and GPU respectively. I would also like to know where the trace is between the CPU and GPU that you would need to cut in order to power them separately. Thanks in advance

Wire the two voltages where it says 1.9v. Attach 1.7v o the pin under the GPU and 1.5v to the pin under the CPU.

That could be tricky if your board is not trimmed. The CPU and GPU are connected near the regulator connector pins by a hidden layer, which is usually cut when you trim a board. The easiest thing to do would be to just cut out the rectangular area with the regulator pins. Sand the edges a lot with fine sand paper if you do trim.
