Probably not as n00b-friendly a writeup but fairly technically extensive and gives numbers down to below 1W/GH board-level if you want to take it that far. With free power there's no real reason to unless you can't deal with the heat output.

Well my reasoning is 3 Antminer S1's = ~360W*3 = 1080W, and the PSU on 120v could only give me 1000W, so if I just pencil mod one of the three I should be able to power all of them with only one PSU and only ~40GH/s loss. Also heat should not be a problem even if I didn't undervolt, I'm going to have 2 fans on each rig. Also thank you very much for the writeup, I will be reading about this.

yes but the mod tends to make the sweet spot for the miners to be 130 gh to 160 gh

so 390 to 480gh with watts dropping from 1080 to 500-600 is more likely what you will get.

but heck since your cost was 10 bucks

400gh will earn 35 bucks before the ½ ing
450gh will earn 38 bucks before the ½ ing
500gh will earn 41 bucks before the ½ ing
550gh will earn 44 bucks before the ½ ing

Is that if I mod all three? Sorry its a little confusing to read. I was planning on only modding one.

I see you're still struggling with this. You should undervolt all of them, if only to a point where you only lose 10GH/s each. The efficiency will be much better, you wont overload your PSU and there will be less noise.

Yeah it's kind of overwhelming, it's my first time doing anything besides a USB Block Erupter. Thanks for the advice, I will see if I can undervolt just little enough to lose like 10 GH/s.

Thanks everyone Cheesy

Just a heads up to how i run my S1's now. At some point, when you have better miners. You only turn them on when you have spare power or need heat (I disabled all heating here). If you undervolt them far enough, you can use them as on-demand heater with no fans = 0 noise (depending on the PSU i guess).

Good to know, I'll probably turn them into heaters (like you said) or just sell them on eBay when I get a better miner.

'The right to privacy matters'

His benefit to do a bit of under volt underclock is more about noise and heat control.

Max setting is 600gh at 1200 watts.
Stock setting is 540gh at 1080 watts

If I was running the s-1 with a hps1200 psu using a 120 line

I would shoot for 600 watts.

The psu would not strain.

The under volt and down clock could be for 450 gh 600 watts.

He could run a fourth one if he can find one cheap.

He can set fans lower.

600 watts vs 1200 watts

That second 600 watts op you gains from 450 gh to 600 gh.

He could try solo mining BTC. OR PPC

Btc block is hard to do with 450gh but a PPC block worth 30$ is a lot easier to do.

Depending on how far you undervolt them, you can run half a dozen on the DPS1200 on 120V. I had at one time 14 undervolted S1 running off a single 2KW PSU.

Okay good to know, current plan is to undervolt the S1's so I can run 3 off one DPS1200 at 120v. That's 300W each, do you have any idea what resistance I'd need for that?

it is really easy and I will find a link

just shoot for 140gh per machine at 180 watts per machine

so 420gh total at 540 watts

all info is here :

This is awesome thank you. Nice to have the chart.

my first try I did with out meters two lite pressure stokes of a number 2 pencil on the proper resisters.

do not press hard.

If your electrical outlet is over 208v, without any pencil mod, you can power up 3 S1 or 3 S3.

If your electrical outlet is at 100-120v, you can power up 2 units. if electricity is free, let the PSU be as is!

Would a DPS1200 work for all three without underclocking and/or undervolting?

Not on 120v. But you *really* should downvolt them. The GH/s loss is minimal vs massive efficiency gain.

Is it easy? Is the downvolting just via this "pencil mod" I've been hearing about? And I have free power so does it even matter? Also if not 3 could I just power 2 with a DPS1200? Thanks.

But with my 120v socket wouldn't I be able to run 3 undervolted antminers on that single DPS1200? Compared to just two normal ones?

I would say yes, you could use them in the winter instead of a heater and you use them for altcoin launches that run sha to try and make an ROI if ever possible.

And if never use them I still think there are 5 dollars worth of parts within them. And also make a decent thing on a mining area spot as decoration. I can't say for sure how much they are worth in part's but 5 dollars seems like heat sinks might be worth that in some cases.

I hope OP bought them after reading thread.

I forgot to check this post! @notlist3d I have bought the miners now (ended up getting 3 for $10!!!). But I am still not sure what I could get that would power them all. Anyone know of any breakout boards for the big 1200W HP proliant power supplies that could power 3 (dual blade) S1's? I was thinking of getting this: http://holybitcoin.com/product/hp-1200-watt-psu-board-bundle/

I never liked the style of board..

that psu needs 240 volts to do 1200 watts .

if you down clock just a bit those miners can be quiet

if you do the pencil mod they become very efficient like 1.1 watts vs 2 watts

do you have 240 power?

Sidehack sent me his new breakout board for testing . it is better made then the ones you asked about.

https://bitcointalksearch.org/topic/dual-purpose-dps800dps1200-breakout-board-1442707

I would get one of these and six cables 2 per unit.

I would look for the pencil mod thread.

I did 430gh at 540 watts with 3 s-1's

vs 600 gh at 1200 watts over clock

vs 540gh at 1080 watts stock settings.

How do I get one of those? Also I have 120v not 240.

It doesnt do super good on 120v. Just to be clear, it does not do 1200w on 120V.

If he takes the s-1's and downclocks plus undervolts via the pencil mod the hp1200 would be very good for him.

If I recall he is a zero cost deal for power.

I was thinking of getting this: http://holybitcoin.com/product/hp-1200-watt-psu-board-bundle/

I never liked the style of board..

that psu needs 240 volts to do 1200 watts .

if you down clock just a bit those miners can be quiet

if you do the pencil mod they become very efficient like 1.1 watts vs 2 watts

do you have 240 power?

Sidehack sent me his new breakout board for testing . it is better made then the ones you asked about.

I would get one of these and six cables 2 per unit.

I would look for the pencil mod thread.

I did 430gh at 540 watts with 3 s-1's

vs 600 gh at 1200 watts over clock

vs 540gh at 1080 watts stock settings.

How do I get one of those? Also I have 120v not 240.

It doesnt do super good on 120v. Just to be clear, it does not do 1200w on 120V.

Okay, would a DPS-800GBA work good enough for 2-3 Antminer S1's (dual blade)?

I would say yes, you could use them in the winter instead of a heater and you use them for altcoin launches that run sha to try and make an ROI if ever possible.

And if never use them I still think there are 5 dollars worth of parts within them. And also make a decent thing on a mining area spot as decoration. I can't say for sure how much they are worth in part's but 5 dollars seems like heat sinks might be worth that in some cases.

I hope OP bought them after reading thread.

I forgot to check this post! @notlist3d I have bought the miners now (ended up getting 3 for $10!!!). But I am still not sure what I could get that would power them all. Anyone know of any breakout boards for the big 1200W HP proliant power supplies that could power 3 (dual blade) S1's?

I loved my S1s in the winter. I used either no fan or a 100% silent fan, undervolted, underclocked, 1W/GHs fully quiet heater that pay its own electricity.

of course you can do something with them if your not paying for power purchase Wink
