OK regardless of pencil mod.

P5E - LLC works as expected
Rampage - random crashes with LLC

The pencil mod is quite literally getting a 'grey lead' pencil and drawing a few strokes where marked in the image, it's tiny. My understanding is it reduces the amount of vDroop by reducing the resistance. It did next to nothing for my P5E with or without LLC, it greatly reduced the vDroop on myu Rampage Formula without LLC. I have not tested with LLC back on yet.
