I'm in Halifax, Nova Scotia. Bitcoin doesn't seem to have caught on very well in the east.

Anyone here in Atlantic Canada?

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,

Total time logged in: 1 days, 3 hours and 53 minutes.

I would probably qualify as a lurker.  There is a lot of insightful and intelligent commentary to take in on this forum.

I need to lose 20 lbs so my pants fit comfortably again. Call it stubborn or cheap, but I refuse to buy new pants.

20lbs lighter would be back to a 4.5 pack.

Raspberry Pi controller +1.
Smaller pool/p2pool if you can afford to run a full node.

Contribute to decentralization.

Antminers: 1x S3, 1x S5.
I plan to acquire three more S5's over the next three months. Working on a discounted power option to keep things profitable.

I realise that staking a bitcoin address may be more important for accounts with more credibility, however I would like to stake a bitcoin address.

Better luck (lately) seems to correlate with slush's switch to version 3 blocks. Is there a technical explanation for this?
