ANTMINER S3+ Discussion and Support Thread

[pekatete]

Both the C1 and S2's are in the same room, right next to each other, so the ambient temp is the same.  The C1 clock speeds are the default of 250.  The S2's are overclocked to 250.  So, both comparison have 4 hashing boards running at 250Mhz.  I'm using the exact same power supply in the tests.  I just swapped the power supplies.  I had the 1300W connected to one, and the 1000W connected to the other, then swapped.  

I am not disputing your results, simply stating the theoretical obvious and trying to pin down the possible cause of the extra consumption.

Don't forget the PSU for the C1 config is also powering the water cooling unit, which is the pump plus 3 fans.  

Assuming the fans each gobble up 2 Amps each @ 12V, and so does the pump, then the extra would be 72 watts, i.e 2 fans and 1 pump, and that would also affirm your test with the 1300 supply.

EDIT: Actually, it validates both tests, give or take for PSU efficiencies or lack thereof. Still, I wonder how far the C1 can be pushed .....

I don't get it either.  I expected the C1 to be lower.  I have a 2nd C1 that got the same results.  I only have 2x S3+ that will do 250Mhz.  I'm not trying to make any points, or get into a debate.  I am simply sharing some data I collected.  Also, there was a question about voltage, and all units have the default setting of 725.

Oh good, if I understand correctly.   You are saying the higher result on the C1 matches the water cooler unit?  If so, then I'm happy that there is a logical explanation.   And I'm sure large environments could get a more efficient cooling system that would support numerous C1's, therefore seeing an improved Gh/W efficiency.

Price for S3+ B11 is $210 per unit now

but I think 0.5 is definitely pushing the highest possible scenarios.

you actually believe that?

Yes, I do. If you didn't have to pay for a PSU, or for power, and just look at what an S3+ at 453 GH/s is capable of mining raw, it will mine about 0.50 BTC in 120 days, so if it cost 0.5 BTC the earliest it could break-even is February. Over the next 8 months, it's only going to mine an additional 0.28 BTC.

If you figure you're paying $0.03 USD per kWh, it now takes you 220 days to break-even with a net profit of 0.01 BTC after those 220 days, for your 0.50 BTC investment, and at 3c per kWh, you start losing money keeping the S3+ operating in July of 2015 (unless the BTC to USD exchange rate goes sky high that is).

Ah, price speculation. The bane of those who continually post some version of "Why the hell would anyone pay x for y miner, because I have mathematically proven (insert *really* simple math here) that you cannot even break even!! If all you people would stop buying preorders the price will drop!! Preorders don't work, EVER!!", and so on and so forth.

A few price leaps up, coupled with some judicious sales, could net back every single penny ever invested (miner, electricity, shipping, et cetera) along with an enormous profit to boot.

If that never happens, those investments are just a hobby. If that does happen, those investments are a hobby with profits.

Many (most?) hobby miners are content with the costs of a hobby they enjoy, coupled with a chance at a profit.

you have probably just summed up what i say to myself every time i roll my eyes at the posts on this forum.
however, we have arrived at a point in time where mining is commanded by massive company farms and price is dictated by market manipulation.
most new miners don't do proper research and/or have more money than sense. once difficulty hits 50billion, there will be very few profitable mining rigs powered up...
this is also worth a  because even when we hit that sum of difficulty, there will still be 'prospectors' thinking they can compete with the big gold mines.

gimme a shovel and a sieve, i'm heading to the hills.

Agreed, 100%.

My point simply being that even at 50 billion, there will be two people happy with their transaction. The person who sold the miner, and the person who bought the miner.

At some point further on, the person who bought it may regret doing so, but that doesn't make the original deal any less than what it was.

I have 2x S3+ that run well at 250Mhz, and I have some C1's.  So I did a power comparison and am sharing my results.

Configuration   MHz Setting   Avg Gh/s   Watts      Efficiency W/Gh      PSU Model
2x S3+            250            1000         903         0.90                     1000W Coolmax 80 Plus Bronze
C1                  250            1000         984         0.98                     1000W Coolmax 80 Plus Bronze
2x S3+            250            1000         821         0.82                     1300W Rosewill Lightening 80 Plus Gold
C1                  250            1000         881         0.88                     1300W Rosewill Lightening 80 Plus Gold

Notes:  Actual GH/s is close to 1000.  2x S3+ averaged 504Gh/s each.  The power usage for the C1 includes the "ANT C1 Mining Cooling Kit" from syscooling.com.

strange results…

i got 780W/1020GH/sec on c1 using platinum leadtek 1150…

There could be some missing info. needed to help explain the difference.  First, list if you are in a 120v (U.S.) or 220v(E.U.) area.  Higher volt. countries will have a little better efficiency. Also, the closer you are to the 50% load on the power supply, the more efficient it usually is  (so a 1000w power supply running 850w will probably run more wattage than a 1500w power supply running the same 850w).  Also, a Titanium, Platinum, Gold, Silver, Bronze or none supply will have different efficiencies.

From what I saw, platinum isn't that much more efficient than gold.

So are you on a 110-120V or 220-240V power source?

115v.  However I'm not posting measurements, as I don't have a C1.

overhead means a lot.  the evga 1600watt p2 power supply coasts doing 1150 watts it is really efficient at that mark.

 A gold 1200 doing  the same will not do well maybe 1195 or not work since you are near its peak.

Just did a lot of testing with the asic miner  prisma and the 1600 watt platinum evga was 30 to 45 watts better running the  prisma then the 1300 watt gold evga.   I posted here for other reasons I opened my bitmaintech account today and I have 84 coupons.  

I have 50 s 4 coupons.  400 each
  I have 17 c 1 coupons. 50 each
  I have 17 s-3 coupons. 50 each

So I grabbed 2 s-3's 5 minutes ago.

Seems I was not checking this thread fucking around  with the  prisma and almost missed these coupons.  


So they last until nov 30th.
So who wants to buy some cheap shoot me a pm.

new coupons are making me think about it  - on the fence about buying new gear to replace the S1s. A lot to think about for sure, but I really don't want to part with any more btc

EDIT: shipping kills the deal for me. Let me know if you need coupons.

If you're interested in skipping the shipping, and going with co-location, I work with a mine with a large number of S3s that are hosted, so they can be lit up immediately after payment, and as it's based out of Washington, USA the power is really stinking cheap!

I say this, because I have 14.4 TH hosted there, and have had an awesome experience with their hosting, and my house is quiet (although cooler now that winter is here), and it's way more hashrate than I could ever power off my regular home line (and even including hosting, it's still way cheaper than my PUD's price per kWh). Industrial power, a secure facility, redundant Internet, and they aren't running in my bedroom. I like it a lot. Can you tell?

yes, shipping is NOT good.
Anyway, I have 19 C1, 19 S3 and 57 (wow!) S4 coupons.
Make a small donation offer for my time dealing with this in PM (up to total of 10 coupons/person) and I will get back to you.

2 cents in Wenatchee, right? I used to live in Redmond and I heard you all get cheap current from the dam.

It isn't my mine, I host there. But I know that the raw power (before rent, Internet, etc) is more than that. I met a couple of guys who were working on getting a co-lo running up in Wenatchee who claimed they were paying 2.8 cents, but they were really shady, and kept going on about raised floors and commercial HVAC, I don't think they actually knew anything about Bitcoin. They came to our Portland Bitcoin meetup to pitch their facility, but their costs (despite having access to cheaper power) were higher than what I'm paying now. Also, I can't easily drive to Wenatchee to inspect the site, whereas I was able to with the one I went with. Also, shady has a lot of sway with me, with how Bitcoin is and how much money there is to be had in running a scam.

I have 10 AntMiner S3 + Coupon 50 USD off that expire 11/30/14.   I am happy to get rid off them for .01 donation.  (Set a price as people are bad about donations and I'm not here to make money just pay for time my C1's were down because of syscooling)

PM me if you are interested.  After the .01 is donated per coupon you want I will send coupon or coupons.  Currently that is around 3.25 for 50 off.

That's not fair. You got them for free. In fact, almost everyone here has them for free and many people will gladly give them away for free. Good luck selling at that price.
