And it has ben stable averaging around 3,4 GH/s for the last 12 hours. Do you still suggest that I should turn the potentiometer to 3 o'clock? And as a back-up check, what should it be at for 150 MHz and 1.5 A (or won't I be able to run it at that?
In post#1 is a table as an overview of the current related to frequency and voltage. If you turn your voltage to 1.26 V at 150 MHz it should run with 1.05 A. So that should be enough.
Do you hav something to mesaure the voltage? On what position is the flat side of your voltage pot now?
