2B Pencil???

i am going to flash my x800 pro to xt-pe. i was looking around and i came up to this site:

on the first post it says
You may need to increase your GPU Voltage. Pencil trick to R1597 resistor will sort this... a few strokes with a 2B pencil will give u just above 1.4v. This can be measured from the silver ring just below and to the left of D33.

What is this all about? does they mean a 2b writing pencil?
if this is a good thing, can i have proper instructions on how to do this.
Thanks

2B is a type of lead (not the element, lead in the sence of graphite that makes black marks ). so yes they want you to use a 2b pencil, but i can't tell you how to do it.

thanks, any1 else have an ideas?

Hey, check out this site:

It tells you exactly what to do, with pretty pictures too. I find drawing around the resistor the best way to do it.

Good luck.

Thanks
