Topic: [GUIDE] Undervolt antminer s1 [1.19W/GH at the wall] - page 18. (Read 69365 times)
Thank you for this! 3.5kohm 150gh 213 watts at wall . going to try for 5 ants on 1 psu evga 1300

Is it the same they will inject us under our skin?
yep I still earn with the machines as is. but when diff pushes 25mill th this mod will let the machines earn until diff is about 45mill th. so maybe 30 or 40 extra days of profit
I did a mild under volt to try and kill some fan noise, 0.96v at 325Mhz gives me about 165GH/s and a much lower fan speed, 1980rpm. Penciled the resistance down to about 3.7k. On stock clock/volts I was getting 180GH/s at 390watts measured at the wall, I assume my Antec bronze 550watt PSU was chewing a fair bit of that. So down to 266watts at the wall, and only lost 15GH/s means a 32% power saving for 8.3% less hashing. Reasonably happy with that, with my high power costs it means more profit.
OK, i give up.. what is that?
thats the size of the component you need to swap out if you want to change a resistor value without a pencil mod
That is what I thought.... I had a hard enough time just hitting it with a pencil
yeah my 57 year old eyes with 2x cataract operations an implanted lens in each eye. then I need reading glasses lots of light and I use this

so A 3b pencil and a quality meter is what I will do.

Nice explanation.
Maybe a 3d printer would make miracles in your ideas.
You don't have any S1? That is the reason for donating?

No, I do not have any S1's (If I did, I would have not asked for a donor-unit. I would have used one of my own.)... I was holding-out for the S2's for a bit, but have AMT's 1.2THs model in-transit. Will be doing some work for them, over the coming months. However, I do a lot of mods, to many things. This thread jumped at me. (Reminded me of the old AMD and PENTIUM mods, for unlocking chips and adjusting clock-speeds. Nice hacks! That and the old "graphite piano", circuit-bending tricks.)
As about snapping on, how could this be done? Glue or something?
No glue.
I fabricate plastic parts, from cheap things... xD (Years of playing with plastic in an injection-molding plant, has led me to make some crazy contraptions from simple PP, PET and HDPE plastics.)
By the looks of it, it would simply "slip-on", just under the HCM1305-R47-R (R47) inductor. Either taking advantage of the unused holes, above the heat-sink-mounting screws, or using the heat-sink-mounting screws to fasten a retainer-clip over the snap-on mod.
The "fixed resistor value", or "swappable resistor", or "tuning pot", attached to the plastic, with the pins protruding for low-pressure contact on the SMT solder-points. (While the original SMT resistor remained in place, unharmed for integrity of the original miner setup.)
P.S. Hot-glue is also great to make prefab plastic parts from. Hot-glue guns are essentially mini-injection-extrusion devices, if you tune the heat.

You can go one page backwards.
Sorry, missed the link above the pic... (You quoted, but left-out the link... Wanted a link to a thread, not just a photo-shoot. Assumed it had its own thread.)
Thanks-again.
No prob.
We need to ask Trend user for his results with the pots.

I am sorry but is already done:
Not quite what I said... "snap-on mod"... But great!
Works with a tuning-pot. (soldering is not for everyone.)
P.S. Got the link to that thread?

You are joking, right?
(A donation, because I can not guarantee its safety, while "playing with the mod".)No I am not joking. I can assure it will be cared for. I just can not guarantee its safety.
Figured that someone-else could use the mod-info, once it was posted. (As opposed to the alternative, which is a great idea BTW.)

Anyone willing to donate an ANT S1, and I will see about making a simple "snap-on" solution to "tune" the ant-miner a little safer?
Pencil-graphite is not reliable to sustain long-term operation. It will eventually absorb salty humidity, from the air, and fail. (Great for a short-term adjustment. Pun intended.)
You don't want that to fail, and your miner starts to pull full power, overloading your PSU. Or, on the reverse, under-volting too much, causing the amp-draw to rise on the regulator, which could stop them from working.
Would be nice to see a software controlled variable voltage control there, or a hand-tuned pot, for some precision control.
