How is the M571 configured to achieve non-standard core voltages?
3.2 version: Obtaining voltages below 2.5v M571 3.2 boards can achieve a 2.2 core voltage level by connecting a 39K ohm resistor from one of the inner (that is, farthest from the edge of the board) pins on JP6 to ground (pin 3 of the speaker connector [on J3], pin 5 of the keyboard lock connector [on J3], and pin 3 of the power fan connector [J2] are all grounds). An error in this process can result in unpleasant consequences, so make sure you know what you are doing. A 2.3 core voltage setting can be achieved by using a 62K ohm resistor in place of the 39K resistor, and a 2.4 core voltage level can be obtained by using a 120K ohm resistor in place of the 39K ohm resistor. Consult Franc Zabkar’s excellent work on 3.2 core voltage settings at: franczabkar/v32corev.htm 3.2a & 7.0 version: Obtaining voltages below 2.2v M571 3.2a and 7.0 boards can be modified in the same way for a 2.0 core voltage level. (These boards come with a 2.2 core voltage level from the factory.) Connect a 47K ohm
