Haven't been here for quite a while and in fact I'm not really in the loop since S4, just took a look at their website.
So why is efficiency going down?
How comes B7 was 5.06 TH/s and B8 only 4.73 TH/s?
Any hint at S7+ or S8?
Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 188. (Read 527809 times)

Same Here, I have 2 Batch 1 units. one of them is slowly getting lower. Now at 4.65 and the other is 4.8 with a OC to 612. Only way I can get it to stay around 4.8. The first unit that getting slower, can't take any OC without err going sky high. Quite disappointed and should have skipped Batch 1
Has anyone received any compensation for any s-7 any batch if it under hashes or if it was late.
My batch 1 came on time as I was a very early order. But it now has become a slow machine .
I don't get 4860 gh as promised .
I never over clocked it. I use an evga 1600 p2 psu. it is providing 11.94 volts to all 10 pcie jacks.
It used to do 4800 then 4700 then 4600 now it is down to 4500. Maybe more like 4400.
So this piece of gear is becoming very disappointing.
my other one is very good So I have a dog and a good one.

my psu's volts dropped from 12.01 to 11.80 and I know that is an issue. Iplayed with psu and it is now doing 12.01 volts.
I think the psu did not get enough space for cooling off and dropped it volts a bit. I will need to keep a closer eye on it for a day or two.
so my good one does 4890gh with .0001 errors
and this troubled one is now back to 4730 at freq 581 with 0.0111 errors
they owe me on time with the good one as it was a few days late. but it runs so well I am more forgiving.

Here is a pic of all of my miners shown (11) right now. I had 3 overheat when the internet went out and I have shipped them back to Bitmain. I am waiting for their return. Electric is about 25% of my total cost per month. That comes out to be about $3700 per month with a ....
Bitmain didnt fix the internet problem yet ?? Did smith already have done a upgrade of the firmware to fix this ??
Wasn't it determined that putting the fans on a manual speed would alleviate this issue?
I think that the OP did not have them on manual. Manual actually is more like an upper limit and at manual fan speed is still fluctuating downward when warranted, so setting manual at 75% (or even 70%) basically solves this for almost all contingencies sans ambient of 40C. 10/23 vs 9/15 soft DOES NOT solve this.

wow... 11 x S7s.... its a long way still for me to reach that level.
With that many S7... I think it's better to put it in proper home like a full fledge DC.
How much does a DC charges in your country?

I had 26 S5's before and sold them all to get the S7's at the end of September.
I have maxed out my electric power and will be installing 20 S7's (11 in the pic and 7 more on order) in a data center in mid December. I will show pictures when I get them set up in a 42U Cabinet.
Here they are in my basement:

Hi Guys,
I have just installed my 3rd S7 with 1 more on the way (Batch
.
S7 #1, v1.7 / 4.66
S7 #2, v1.7 / 4.66
S7 #3, v2.0 / 4.46
S7 #4, Batch 8
What batches are the first 3?
All at clocked at 600mhz, and all them at frequently touching 5TH with 50% fan settings 3600-3720 RPM steady at 57c-61c temp.
The HW errors are also very low at 0.01%
I am really pleased with my vertical design, because now I can house them in soundproof cage and improve the heat exhaust greatly.
Thanks to all the expert advise from this thread and others. Let me know if I can further improve my rig.
Note: I will post some pix as soon as I figure out how to do it ...:-)

I don't care, just don't want to buy the 700M machine, so I am waiting for Batch 8...
Just think about it:
Batch 8 uses 1293 W to get 4.73 TH/s = Actual Efficiency: 0.2734 J/GH
Batch 7 uses 1278 W to get 5.06 TH/s = Actual Efficiency: 0.2573 J/GH
Batch 6 uses 1042 W to get 4.05 TH/s = Actual Efficiency: 0.2572 J/GH
Batch 5 uses 1210 W to get 4.86 TH/s = Actual Efficiency: 0.2490 J/GH
Batch 4 uses 1160 W to get 4.66 TH/s = Actual Efficiency: 0.2489 J/GH
Batch 3 uses 1210 W to get 4.86 TH/s = Actual Efficiency: 0.2490 J/GH
Batch 2 uses 1160 W to get 4.66 TH/s = Actual Efficiency: 0.2489 J/GH
Batch 1 uses 1210 W to get 4.86 TH/s = Actual Efficiency: 0.2490 J/GH
It is all about efficiency 24 hours a day!
Looks to me that the Efficiency is going down.

I don't care, just don't want to buy the 700M machine, so I am waiting for Batch 8...
well if everybody waits there wont be a batch 9 lol. I got a batch 8, i'll be honest. i'd have gotten a batch 7, but i was a few coins short. any case, I dont get the hate over the batch 8...there is a lot more to it than just a higher clock rate
edit: I would prefer a 7, but after my purchase i had 0.025btc left
im not rich like you guys

after a hour of looking at what could be wrong I may have found the problem. may be my error.
my psu's volts dropped from 12.01 to 11.80 and I know that is an issue. Iplayed with psu and it is now doing 12.01 volts.
I think the psu did not get enough space for cooling off and dropped it volts a bit. I will need to keep a closer eye on it for a day or two.
so my good one does 4890gh with .0001 errors
and this troubled one is now back to 4730 at freq 581 with 0.0111 errors
they owe me on time with the good one as it was a few days late. but it runs so well I am more forgiving.

Has anyone received any compensation for any s-7 any batch if it under hashes or if it was late.
My batch 1 came on time as I was a very early order. But it now has become a slow machine .
I don't get 4860 gh as promised .
I never over clocked it. I use an evga 1600 p2 psu. it is providing 11.94 volts to all 10 pcie jacks.
It used to do 4800 then 4700 then 4600 now it is down to 4500. Maybe more like 4400.
So this piece of gear is becoming very disappointing.
my other one is very good So I have a dog and a good one.

Yes I am sure there will be one. The interesting "game" is guessing what it will be? Will it be a chip count / speed that we have seen already or something new?
Following the recent trend I think we are due for another 162 Chip Miner perhaps the same as Batch 7 with 5063GH/s? Although pending further information on exactly what the changes are and some feedback from people taking delivery I am liking the look of further releases of a Batch 8 style with 135 chips & 4725GH/s.
Rich
I'm hoping for something along the line of batch 3 at least...less wattage and more efficient than this last one.
My opinion is when the new rig put up for sale has less hash rate while consuming more watts it should be priced lower. At present, the rigs are priced at .001 BTC per GH/s. When the rigs are lower hash rate and less power efficient, they should be priced at 0.0009 BTC to 0.00095 BTC per GH/s.
4,730 GH/s x 0.00095 BTC = 4.4935 BTC + shipping
4,730 GH/s x 0.00090 BTC = 4.257 BTC + shipping
November 25, 2015, 06:06:50 PM
i'd say S7 "+" would be coming soon
162 chips version (using the better chips production batch) x 2
single controller
10.5 th/s, roughly abt 11 th/s +/-5%
power has to be 12V +5% & up
price won't be cheap, 11 BTC ?
it's a pre-order !
just my guess . . .
