Hello, I am relatively new to this board and was wondering if I could get some help with a pencil mod. I have little knowledge of the procedure but understand you must shade a resistor in order to solve a v droop problem. Well I have an EVGA 780i SLI mother board and I think I know where the resistors I am looking to mod are. I don't know what to do in the next step. I know you must have a 2B/4B pencil (Have no clue what the numbers mean or where to get a 2B or 4B pencil) and I think you have to shade it 2 to 3 times back and forth. Anyways I'm pretty ignorant of what I need to do and could use some help. It's killing me to have a Q6600 (SALCR) and have v droop so bad that I have to set CPU voltage to 1.58v to be stable at 3.6ghz. Once again any help would be appreciated.
