Also do i have to do this to both boards? or will doing it for one board apply it to the whole thing?
both blades, 8 resistors in total
I guess i should just wait for the youtube tutorial.
4 resistors per board. Both boards would have to be done.
Also do i have to do this to both boards? or will doing it for one board apply it to the whole thing?
Is there a way someone can make a quick tutorial for this please? I'm too dumb/blind to see what to do.
I should have mine posted on youtube later tonight. I will post a link here after it has uploaded.
THANK JESUS!

most likely it would. it has ohms at 20000. the 8 stock resistors should read 4470 so if you set the ohm part of the meter to 20000 you should get 8 readings close to the same.
if you do the 2-3 pencil strokes it should drop to 3000 as long as the 8 resistors are all close it is the only reading you need.
mine range from 2.9 to 3.4 k or 2900 to 3400.
i allowed for that much variation on purpose so that I could post on this site that perfect ohm readings of 3200 or 3.2 across the board are not needed to work.
I'm confused, which "pins" am i supposed to add the strokes to? This is why i am desperately in need of a video tutorial.

Hello miners,
My undervolt using 10K potentiometers in parallel with the smd resistors...
Used double-side tape under the potentiometers and soldered directely to the PCB.
Easy way to adjust voltage.

if you have the skill set to do the work it is the best way.
I wonder if the new s-3's will be reducible to .5 or .6 watts from the .78 watts .
obvious that we are talking about doing thus mod in 3 or 4 months. not right now

Thanks for the replies. I guess I will try it again another day or something. Just sort of intimidating for me (like the first time you change a spark plug or something, your afraid your going to break everything.)
the key to it is do not muscle the pencil . 2 or 3 medium pressure strokes on each of the 8 resistors. the ohm's should drop from 4.47k to 3.2k or so
then set freq at 325 300 or 275 or 250.
check the freq got set at one of the above. then check your hashing make sure the hw are pretty low 1 out of 80 or better is good. make sure no x just o n the two asic lines. if there are a lot of x try a freq lower..
I started with 325 on all three and it sucked.
Then 300 and only 1 was good no x's 1 out of 75-80 errors.
Then 275 on the other 2 they were good no x's and 1 out of 110 errors.
300 is fine with 3.3 - 3.4 k

Any videos of this anywhere. Way to confusing for me without a video 
All the pencil mod ones on youtube don't use voltmeters either?

It's super easy to do! Don't even have to check the voltage to get decent results. Just check the Ohms before and after applying the pencil. I will see about putting a short video up for the S1 pencil mod.
8 resisters 2 or 3 pencil strokes on each one.
ohms before 4.47k ohms after 2.9- 3.4k
I allowed that much variance on purpose.
Why because I wanted to see how forgiving the s-1 would be to less then perfect ohms. I did 3 s-1's two run at freq 275 one runs at freq 300 .. they pull 560 watts and do 420gh more then a month now .. no adjustments of any kind. watts stay between 555 and 565 hash stays near 420. I can begin to say how easy this is to do.
don't muscle the pencil strokes . I used less pressure on them then when I write with a pencil. if you resisters stay between 2.9 and 3.4 you should do around 140gh a machine around 185 watts
I had 5x S1's running off a single 1000 Watt PSU
The hardest part was finding the frequency each miner preferred (lowest HWE etc) Any videos of this anywhere. Way to confusing for me without a video

Sure do! sorry for the bad pic, I put it into service immediately
Hot melt glue, 10K pots, works great!
If you have the skills it's the best way to go.
Congrat's. Got pic's?
