In respect to RayJay who provided the pictures and the instruction, i want to share this with you.

It is quite simple after you have dismanteld your S3.
Find the resistor with 2,088KOhm

Measure the resistance

Apply pencil to the side of the resistor until you are somewhere between 0,900 and 0,950KOhm.
With 0,900KOhm and a the Frequency set to 150Mhz my S3 is hashing at 310GH/S with 185Watt on the Wall constantly.

Happy mining Grin

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,
