ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

[pisquare]

I don't know the exact answer to the difference of 4.86 and 4.66 miners however I can still share my experience with them.Having the chance to own them both I have experienced that the 4.86 are durable where 4.66 are error prone due to the material.To be more open 4.66 breaks down (infact fins fall out) 80C heat where 4.86 resist.The main difference is the chemical compund of epoxy used and its charachteristics.The 4.66's PROBLEM were realized and Bitmain switched to a stronger heat resistant epoxy.As a matter of fact the 4.66 were 4.86 when weaknes against heat was detected the two chips were just cancelled out.If you can remove the cover you can use the chips as spare.Good Luck.

Has anyone purchased and received the new ANTMINER S7 BATCH 16 with One Fan?  If so, let us know the stats on this machine, especially temps. 

I have found that the batch 12 run about 10 degrees calculus hotter than previous models.  Does anyone else see this same condition?

Yesterday i purchased a Batch16 S7 with a second FAN thanks to your coupon 
As sson as i get it, i'll post the performance with SINGLEFAN usage and DUALFAN usage

Arrived, unpacked, configured, runnning.
Without modification, you can not adapt a second fan. My S7 B16 is new, without dust, smells new and tastes new. Running like a charm after almost three hours in ambient temperature in my room at 65°C 
See the pictures for yourself

how come u found 7 blocks in three hours and I haven't found one in weeks?

he isnt mining bitcoin.. he is mining an altcoin or nicehash

Looking at the pool name, he is mining DGC (Digitalcoin). It can be mined using Scrypt, X11 and SHA256 algos.

My buddy called me today to tell me that he finally ROI on his Antminer S7 Batch 1 that he bought back in September 2015.

He was pissed at me actually for introducing him to mining and didn't understand how difficulty was calculated and everything. His electricity was free at work and he usually sold all his coins for cash every 2 weeks or so.

And today was the day he finally ROI'd on the miner + shipping.

He is upset because after 7 months he only made like $400-500 USD (value of miner itself) and the miner cost almost $2000 USD at the time. He is debating to sell the miner now for $500 or mine a little more and sell before halving, however by then it might only be worth $200 and will make him only $200 more then what its worth today.

Economics 101: It is impossible to make a profit in a perfect market. Mining Bitcoin is as close to a perfect market as you can get.

Consider it a lesson learned for your friend.

is there a tutorial on how to remove and reseat the heatsinks?

Look up posts by cypherblc. He's got a write up on removing them I think.

Has anyone bought and done some testing on the single fan batch?  What were some of the results?

I bought a single fan unit.  It seems to work very well.  It is much lighter and a bit smaller than my s3's.  I have it on its side so the heat sinks are pulled by gravity toward the chips.  It is a little like a rocket, so that must be one powerful fan.  Denser heat sink fins than older s7's.  Loud, but don't know how it compares to other s7's.  Stable at 700 MHz, and I think it's a little faster (GHs/s) than older s7's but I'm not sure.  I'm a little worried about a single point failure on that single fan.

Does anyone know if s7's can support mining two pools at once?

What kind of epoxy are you going to use?Are you familiar with temperature resistant alloys/compunds?If you apply excess heat to the board the epoxy will not function and you can move the heat sinks (I call them fin).However, you can program and use a work station or a robotic arm if you need to this for a large amount otherwise you do it manually.According to the type of the compound your procedure will be different.However, if a fin has fallen out and if it is in the middle, so you can not reach it easily and remove the others you may prefer to bypass them by a copper.You may use 22 to 26 awg copper to create resistance so the circuit will function and so you can has without malfunctioning unit.

The intake and outtake performance of fans are not same so one fan can easily cool down a S7 under normal conditions.In summer, it is not normal conditions for a large percentage.You can trick any system by connecting parallel fans or multiplier.I recommend you to use a back up fan incase of one of your fans failure.Is there a brand for the new fan?Any specifications or data is very much appreciated.

so when a miner arrives with some heatsinks rattling around.. and you want to properly re-adhere them prior to starting the miner up.. how are you supposed to do so without removing the "warranty void if tampered with" seal on one of the screws?

do you have such a miner or is this a hypothetical?
I've got seven S7, none were rattling, but it surely does happen sometimes.
if so, don't start the miner, contact Bitmain for instructions-they will give you permission to open it up, but without proper glue, i don't see how you can fix this yourself-most likely would need a RMA.

It does look nice if it works good with one fan could have been a smart move.  One thing I wondered was how easy is it to look to see if any heatsinks have fallen in shipment?  It appears from picture it might be hard and there is a warranty sticker so can't unscrew.

And I could be all wrong. But just looked hard to see back heatsinks that should be checked before hooking up.

Yeah, but careful shaking should reveal if some of the heatsinks have fallen. Unless they have forgotten a heatsink or two in first place, that's a different story then.

Well, if something is loose you will here it ratelling by unpacking the device. In my opinion, this batch has the best manufactured quality and my S7 B16 was really NEW! No dust, no scratches, so i believe you will get the best for your money from Bitmain

can u please share some screen shots, what's the temps at?

and no I don't recon the s7 or any miner for that mater can mine from two pools at once but it can automatically start mining from the next pool if one is dead, just place the other accounts in the configuration.

bitmain does not seem to respond to their emails very promptly. i waited 3 days for the first correspondence, and on day 4 (including weekend) of the follow up.

is it possible for the hashing boards to have some play in them and make some noise in light back/forth of the miner or should it be rock solid with no noise if you shake it a bit?
