Memory Volt-Mod

As I wrote above, the regulator of the memory voltage is identical to the GPU voltage regulator, so it can be modded in the same way: connect a 20,000Ohm resistor to leg 4 of the regulator with one lead and to the ground with the other lead (you can use the leg of the neighboring capacitor for that):

The memory voltage can be read from that capacitor:

DDR2 memory works at 1.8V by default.
