Bottom Line Up Front: is this modification a "one-way street"?

I'm more a software guy, but I'll take a stab at this.

Postulation: The graphite from the pencil enhances the electrical conductivity of the resistor, effectively lowering its resistance. The result: voltage supplied by the S3 hashing board to the BM1382s is effectively reduced.

If the above is correct, I pose the following:

1. Can the S3/3+ chips run at their default frequency/clockrate once this modification is applied?

Experience with CPU over/under clocking+volting leads me to believe that if the voltage supplied is less than sufficient for the desired frequency, the chip will either fail to initialize or initialize and misbehave. See #2 particularly if false;

2. Can the graphite be safely removed?
(Methodology requested if true).

Thanks,

The simplest answer to #2 is to use the other end of the pencil (i.e. the eraser). You could also consider an alcohol soaked swab. The graphite isn't permanent by any means. You are just trying to clean it off, it isn't embedded nearly like it is on paper.
