Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH
Anybody have an S7 coupon they can't use and willing to donate?
Are people getting coupons? At least I didn't get any on my batch 1 order.
If the temperature is -20 in your area, why not put the miner in home to get some heating out of the miner?
The amount of heat output is not enough to heat an ENTIRE house.
That really depends on many things:
1. The size of the house
2. How many miners you have
3. The temperature you want in the house
For example I'm okay with around +15C in my room so even one miner would be enough to make me feel comfortable. Of course I live in a flat surrounded by another flats which are warm.... so maybe tha's why ... Yep, for the entire single house one miner is definitely not enough.
You're seriously comfortable at 15C inside?
Are you wearing wool? ^^Re: My set-up to heat house using bitmain S7 (UPDATE 03JAN2016)
Quite a good idea to be honest, I like the way you are saving money on heating and using that to run the bitcoin miner, very efficient 
I disagree that. It is not efficient simple reason that miners will not earn money back because difficult level rising all the time and when you use example 1000w keep miners running you will get only 1000w heat. If you use air source heat pump you will get 2000-6000W heat per one 1KW so it is much more efficient for heating than running miners.
So you have to spend 2-6times more electricity when using miners compared heat pump or other efficient heater to heat house for same temperature. Keep that mind when doing calculations.
I see your point, but you can't really compare the two.
Sure, if your goal is to use as little electricity as possible to heat your house, then there are more effective ways. Insulating walls, roof, windows and burning wood comes to mind.
Throw in a heat pump in the mix and you're good to go.
But, if you eitherway are going to mine, its more efficient to use the heat, instead of just pumping it out of the house.
This is how I do it:
Family and friends are heating their houses with 1000-2000W electrical heaters. So I replace their heaters with miners. I pay half the electricity.
They get: Same heat for half the electricity price.
I get: Location to host miner, half price on electricity.
This is how you ROI a miner today
Re: My set-up to heat house using bitmain S7 (UPDATE 03JAN2016)
Like your setup mate! I'm also heating a house with miners, if u wanna check it out here's the link: https://www.youtube.com/watch?v=mfmfdEjRkWU
I badly need to insulte the room because of noise with the S7's, would you insulate the room in the video, or create a box like you did, inside the room instead?
Do you know the amount of dB your setup makes?
Thanks

Nice set-up!
Insulating the room would be easier but prob would still be louder than enclosing the S7s with an insulated box. The box is more of a hassle having to cut ports for the air to come out and air going in but would enclose the sound to a smaller area. Either would work good. Just make sure the insulation is both fireproof and sound reduction.
I did not have a dB meter to test the difference but it is incredibly quieter! (10x quieter)
goodluck!
whatever you end up doing please take pics!
Came up with a redneck solution instead, has killed the high-pitch sound, so its not a problem anymore.
What I did was basically make sure all the miners get direct cold air from the outside, which made the temps go down. And then the fans didn't have to work as hard anymore, problem solved (for now).

Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH
so what my best option to power one of these. i have a 240v 30amp circuit available.
was looking at there power supply and it seems to be efficent but didn't know if there is a better and cheaper option?
Thanks In Advance

Bitmains PSU is the best for the purpose IMO. If you go for a standard ATX PSU with 1300W+, its gonna be huge, expensive and "hard to work with" aka messy.
Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH
So we have installed a bunch of S7's on our network along with our existing SP35's. Every time we power on the S7 racks our whole network goes to shit....We have >150 SP35's and just installed >200 S7's. They are all static IP's on our 10.x.x.x VLAN. We've got layer 3 switches, and Pfsense router that can handle over 8 million simultaneous connections..... I don't understand what the ants could be doing to cause such havoc... Any thoughts would be appreciated. Day 3 of no sleep trying to figure this out....
Whats the hardware specs on the router? What switches do you have?
I just did a wireshark capture of the traffic from a miner. It basically just sends traffic back and forth the pool, and occasionally some ntp traffic. So no broadcast noise or anything like that.
I'm gonna put my money on crappy switches
You could try seperating the miners into smaller groups on their own VLANs, and if possible balance some of the load from the different VLANs onto different interfaces on the PFsense router.
Do you have a topology drawing? I'd love to help you out if I can.
It is sure now that the YES Miner folks are a scam!

Thats way too cheap, isnt it?
And 110TH @ 2U? Is that possible?
Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH
So, could you guys post ur hashrate and temperatures?
I'm pretty sure you get lower hashrates if your temps are below 45-50C.
At the moment, some of my S7's are getting cooled by direct -17C outdoor air, which keeps the temp on the boards at 33C (Thats what the sensor says anyway.., not sure if this is accurate when getting blasted by -17C air). The hashrate avg is 4.7TH/s @ 625Mhz
Some other S7's are "cooled" with indoor air, which keeps the temp on the boards at 65-70C, these are hashing at 4.99TH/s avg. @ 625Mhz.
The ones cooled by outdoor air used to hash at 4.99TH/s as well.
Conclusion:
Board temps below 45-50C = Bad? ^^

Re: Antminer s7 small farm almost free electricity profitable?
If this is true, I would kill for this opportunity. If you truly have free electricity, it's a no brainer in my opinion.
I would probably invest in S7's, you get warranty, better GH/J, and more GH/m2.
If you are not limited by m2/squaremeters, and could get used S5+ from a trusted source, it would probably be a good idea to get some, as they probably give better GH/$.
Surely you have a limit on your free power? In that case I would go for the S7's.
Btw, if this real, I want in.

If you get good units, they will probably last "forever".
Nice setup in ur pictures. The only tip I got would be to not strip/tape the power extentioncords together like you have in your picture.
Getting 30 S7's in there, and putting them together like that would probably generate some heat!
Happy new year!

nothing last forever, every HW is subjected to thermal stress, and they have a precise lifespan, this si the case for gpu too, even if well cooled after some years they will break
"forever" as in as long as they are practical to run!

Price of import = sale price of items (or fair value) + shipping ACTUAL cost. The amount you were charged for shipping was possibly less than it actually cost to ship, meaning the declared value comes out higher. + exchange variations.
This!
I was confused about this in the beginning as well, but Bitmain haven't done anything wrong here.
Something weird happend today.
4/6 miners lost connection to antpool, probably around the same time. 1 of the 4 are hosted in another part of town, with another ISP aswell.
All the miners have the same config.
The GUI also reported that they where hashing at 300 GH/s (S7's), with no alive pools.
After a quick reboot they are back at 5TH/s.
FYI.
Edit:
The two that didn't lose connection, kept hashing as normal @ Antpool during all this.
PS: I could hear _1_ single beep from the miner before this happend. Kinda sounded like the same alarm you get when you lose internet connection, except it was aborted after the first beep.

Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH
I kind of lost track. What was batch 4 rated at? And if it was a 4.6 miner what was the 4.8 batch that was selling along side? Was it batch 5 or batch 3?
Batch 1 - 4.86, some slower
Batch 2 - 4.66
Batch 3 - 4.86 alongside batch 2
Batch 4 - 4.66
Batch 5 - 4.86 alongside batch 4
Batch 6 - 4.05 preorder for December
Woohoo my B4 shipped also!
I bought Batch2/4 just to save a little on BTC and power draw and it seems like the "slower" 4.66 batches always shipped out promptly. My B2 shipped fast, was all Rev 1.4 boards, and performs amazingly well.
"ANTMINER BATCH 4 is with 4.66th/s hash rate and shipping may start from Nov. 23~Dec. 3"
Bitmain BEAT the estimated ship date by full week from the earliest estimate! Go Bitmain!
Is this real? Not just PSU?
Re: [OPEN] [Group Buy + Group Hosting] 3.5TH/s Avalon6 + Platinum PSUs!
This i my ROI point of view:
This calculation is based on the fact that you have the money to pay for the miner package + hosting for a year, on hand, so that the alternative is to buy coins instead of mining gear for that amount of money.
Calc inputs:
Difficulty increment: 4% #I seriously doubt it will be below 4% on average.
Pool fee: 2.5% #Based on Ant PPS. Even if you are mining on 0% fee PPLNS. You can't expect more than 98% luck on average IMO.
Hashrate: 3500 #Based on 3650TH/s -4%. They have stated +/- 5%, lets try to be realistic.
Hardware price: 1436$ (Ex. hosting/PSU rental)
Hardware price in BTC: 4.373
Watts: 1000
Start date: 11-30
Maintain cost/month: ~58$ #Based on 0.0661$/KWH aka hosting, and 10$/month PSU rental
url snipped
Seems like you will never earn back the amount of BTC you put into this.
Miner cost + 1 year hosting = 1436 + 696 = 2132$ total invested.
If you buy coins today for that amount of money, this will give you 6.41 BTC.
If you buy gear, you pay 4.37 BTC up front, which you won't mine back. Unless you get cheaper hosting or $/KWH.
PS: There are 3 months of hosting at 0.047$/KW, that is not considered in this calc.
PS: Calc does not take halving into consideration. If you can't ROI without halving, you probably can't with it either
Am I missing something?
Better to buy coins than gear, in terms of ROI?
Disclaimer: You can ofc ROI this in terms of $, if BTC price skyrocket. My point being, it's always better to buy coins.

you are not putting btc into it, but $$. Don't put in bitcoin that you already have.
these calculations never account for btc price change, and therefore cannot be trusted.
Start with $$, end up with $$ and put in various bitcoin price scenarios.
Besides, where in your calculations is the RESIDUAL value for the miner?
It was ~55% in BTC and 35% in $$ for SP30 after 12 mo and 53% of SP20 in $$ and astonishing 78% in btc after 10.5 mo (even with a high price paid for SP20 before discount to $400-500).
My example is more like buy btc OR buy hardware go get btc. At least thats what I was trying to do.
