Re: ANTMINER S3 Discussion and Support Thread.

Has anyone had experience routing shipments to multiple addresses from Bitmain? Example, I buy 2 miners, one that needs to go to Texas, and one that goes to California. Can they do it through their site, or do I need to do it through UPS? Curious if folks have done this before.

you can't do it mate, they are requesting you to buy 2 in a single order only for a better covering of shipping expenses.

Just choose one destination (for ex. Texas) and when you receive the two s3 send one in california with a domestic, inexpensive shipping

Bummer. I can re-route them via UPS once it's shipped, but that's a hassle for multiple units. Oh well, I guess that's the only way to go about it. Thanks for confirming!

Just a heads up, we sell single units - scope my sig  Smiley

Appreciate it, but as someone who is selling them as well, the cost plus shipping would eat into my profits. Smiley

Quick power #'s, measured with my best unit.. and the only one that will hit 500GH.

Corsair TX850 80plus bronze PSU - single S3:
218 mhz -- 450 GH --  346 watt at the wall
225 mhz -- 480 GH --  370 watt at the wall
237 mhz -- 500 GH --  394 watt at the wall


I was a bit curious myself and tested one of my batch one units, but I'm getting different power numbers at the wall. See below:

218 mhz -- 440 GH --  360 watt at the wall
225 mhz -- 387 GH --  348 watt at the wall
237 mhz -- 408 GH --  360 watt at the wall
250 mgh -- 424 GH --  345 watt at the wall

I'm using a Corsair HX650 for each unit and testing using a Rosewill RHSP-13001. I've only tested one S3 thus far but there appears to be a power issue, or it's just not liking anything outside of stock frequency. I haven't flashed the firmware yet but am more concerned that I'm not pushing the same power to the unit at those higher frequencies. Any thoughts?

How does this hold up in heavy rain? I see the insulation but between the dog door and vents I'm sure moisture gets in there. Do you run any dehumidifiers or anything like that?

Great question! The dog door is completely separate, with the port inside the shed double sealed. The exhaust vents are on the hot side, with our insulation wall separating it from the miners. it's also about 20 degrees hotter than the "cool side". The other vent we have is for the A/C, and we haven't seen any issues with moisture on that end. We've had some pretty major rain storms and the shed has remained dry, so I think we're set.

Awesome farm! I was thinking about setting one up for a couple of GPU rigs but nothing on the scale of what you're doing. I love the wifi controlled lightbulb, that's a really good idea.

Have you run into any issues with the miners since setting them up there?


The PSU's have been the biggest issue thus far. We're using the 835w IBM PSU's, one for every 2 miners. They have a nagging habit of shutting off and you have to fiddle with them to get them back up. Luckily we're getting them for between $10-$14 per, so I'm not too concerned with having to replace them. Other than that, there's not too many issues we're facing yet. Very curious to see what happens when the outside temperature starts climbing. We've had a very mild spring and haven't really climbed into the Summer temps yet (100+ f). I would imagine there will be some more tinkering in our future to combat that.
That's quite a project, and what a deal on those power supplies, $10-$14 per supply is an awesome deal!

Yeah, the PSU's have been a pretty good deal. We've purchased them off of ebay, and there are still plenty available for those willing to do the wiring themselves. Here's a link to an auction as an example: http://www.ebay.com/itm/IBM-24R2730-24R2731-835W-POWER-SUPPLY-FOR-X3400-X3500-X3650-SERVERS-/251542456212?pt=US_Server_Power_Supplies&hash=item3a91194794

Thanks for all the replies and thoughts. I may have spoken too soon regarding the issues. Currently we are sitting at ~100-110f on the cool side. While the miners are still running just fine, both Shaxs and I are concerned we may be facing some trouble once the temperature here heats up. I'm going to try and develop individual shields for the miners as the heat emanating from the sides of the miners is a major cause of the heat spike.

Speaking of which, has anyone developed heat shields? If so, what materials did you use?

I'm sooo fucking pissed right now.

I was sure I could use them on may 29th. Coupons are now disabled 38 mins after I was ready to buy them ...



Dang man, I'm sorry to hear that. Maybe send them a note to see if they could cut you some slack? Or post in their thread?

Wow, you blew $4500 just setting up the room!  Kind of defeats the purpose of mining.  It's hard enough to make a profit without piling another $4500 on top of that!



Hosting would have been anywhere from $1,100-1,300 per month, per person when we only had 15-20 miners. With what we have now, we will hit full ROI in another 2 months or so, maybe less with the spike in price... Pretty easy decision in my mind, and I didn't have an issue putting my money to that.

Trust me, we weighed every option we could, and this was the best option, hands down!

so after sealing up the wall we're sitting at 86 degrees f on the cool side and 124 degrees f on the hot side. This is with the 32 miners running, and it isn't extremely hot outside yet. Shaxs and I are going to tinker with individual shields for each miner to try and contain the heat they put off so it's funneled directly to the hot side instead of outwards towards the other miners.


This is like the never-ending project...

I am very impressed with sincerity of your effort and workmanship. Much to learn here.

However, I have to question economic viability of this project, due to your need to pay for air conditioning.

Air conditioning in Dallas will probably triple or quadruple your power bill, compared to a naturally cooled installation, and cost of power may make bitcoin mining unprofitable much sooner than for those without the need to pay for A/C.


True the ac doesnt help. It uses about 1500w, or 3.5 oc'ed antminers worth of power. Based on my power rate, thats about 3.64 USD per day. Not horrible. Not great either. Also, if we leave the door to the shed open when home we can shut off the AC.

If you do not need AC when the door is open, then what you need to do is get rid of the AC, and instead install an exhaust fan. You will pay a fraction of the cost of electric bill.

There are already two exhaust fans. They were not enough to keep the shed cool enough. One is an attic exhaust fan. I also cant leave the door open during rain or when I am not at the house.

good work. I can't keep mine cool enough either......July in TX will be a challenge

No doubt. As the business partner Shaxs referenced, it's been a fun challenge to organize, structure, build, wire, and administer our little frankenstein shed. Having said that, I'm extremely proud of what we've been able to put together, and am extremely curious to see how it performs in the Texas heat. We also have 6 more miners on the way, so there will be more wiring, positioning, and administrating.

I may try out building shields for each of the units as well. I've seen some folks use cardboard or aluminum, and I'd like to see if that can drop the temps on the units, even if it's just by a couple degrees. Never-ending tinkering!

3 more antminer S1 units came in today - 4.5TH Smiley

http://i.imgur.com/iPQxGKH.jpg

however, 1 unit arrived with a lot of thermal paste leakage, and another took damage to the capacitor (see pic below).   


Nice setup, can you advice whats you using on side of S1? is it wooden board or plexi glass ?

a few units i cut out some thin cardboard (the type for frozen pizza boxes) in the right shape to  fit well on the gap of the antminer and try to improve the airflow going through the entire length. It works, but I really want to make myself some exact measurements and make more of them properly using thicker cardboard or even some very thin plywood/plastic that will be less flimsy.

the satck of 3 units just has a big box lid pressed against it, held in place by the power supplies. it does a nice job at getting the temperatures down slightly. I plan to add to these stacks a little bit soon once i figure out some more power supplies that use PCIe cables (since when stacked the screw terminals are inaccessible)

Thanks for posting this. My business partner and I have been dealing with some heat issues on our setup (26 S1's in a dual-zone shed), and with the Texas heat coming we're looking for additional ways to cut down on the heat these things pull down. Hadn't thought about adding barriers around the stacks.

I received 5 .05 and 6 .15 coupons this past week. Just curious, are these one per transaction, or do they stack? Are they transferable? Does the coupon ID only work with my account? Thanks in advance for the information here, I've never used their coupons before.

They are one per-transaction, do not stack and are not transferrable.

Thanks for the response and clarification. Bummer on all fronts, but I suppose it makes sense.
