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

Still no sign of the promised compensation. No reply to an email I sent asking about the compensation.

I didn't bother with creating a support incident because that has never been effective for me.

We were asked to be patient but I think that time has come and gone. I would also like to see it be taken care of.

Anyone know if the S7 can be underclocked? If so, what are the power consumption/hashrate?

Anyone know if the S7 can be underclocked? If so, what are the power consumption/hashrate?

by simply lowering the frequency in advanced setting (say from 600 to 575 or 550 Mhz).
However, efficiency stays at ~0.25J/Gh regardless, so there is not much point of doing it, unless you want it to be quieter.

[bomberb17]

I will put it in a small room, and I don't want the room temperature to go very high, so I want to be able to underclock it.
Another question: Is there a way to change the web interface port from 80 to a 5-digit port? I want to use port forwarding on my router so that I can be able to remote control it.

[pj40]

My question is, can I use 2 HX850's to power up the latest batch?  It's getting close to 1300W.  I am currently running my B3 on 2 HX850's right now and it's hashing along fine.  But how much wattage do these boards draw at 700 MHz freq?

Assuming you know what port-forwarding entails, the simple, straight-foward way would be to simply do your port forwarding to the defaul port 80 of the S7 on your gateway. (EDIT: You'd need SSH access to your gateway so that you change the gateway's default port  from 80 to another else you'll not be able to access the web interface of the gateway anymore!)

A more involved way, if you can not get the above to work: I think S7 uses lighttpd (lighty) as its web server, so all you'd need to do is change the port in the lighttpd.conf file (not sure where they keep it), but whenever you try to log-on locally, you'll have to append the port number to the IP. For external log-on, the port forwarding will cancatenate the port for you. Remember, after changing the conf file you'll need to restart lighty.
EDIT: Also ensure (if you use the latter) that the said 5-digit port is open in the firewall settings of the S7.

Anyone out there doing remote monitoring or access to your S7s ?

I tried the Minerlink thing at Bitmain, but doesn't seem to work.

Any good way to do the monitoring / access from outside?

Someone recommended "teamviewer" but i prefer a freeware solution?

I would like to monitor hashrates, temp, etc and ability to reboot the S7s.

Have you seen this one?

EDIT:  You may still need to use Teamviewer to reboot.

Teamviewer is free for personal use

It is it is quite fair they give a pop-up when you log off on computer saying like ... this is personal use if business use purchase key here... So it is not bad one box to use what really is a quite good remote desktop.

The good thing about it is it's tied to username not IP.  So if for some reason you lost power and IP changed you can still log back into it through username.  Also it has Iphone and Android apps so you can connect from your smartphone.

I have used it for two years.
The trick is to have a pc at the remote site . Just a cheap laptop would do it. Can't tell you the pile I have of those.
I have two pc's at my remote just incase one gets funny.
No router configuration or port forwarding.
Teamviewer guys just dont want you controlling 10 pc's at the same time unless you pay. One or two.
I know I got it to work on ubuntu also. Don't think I would put it on the beaglebone on the antminer.
I use m's miner monitor or  multiminer on the pc. m's multi miner allows you to see what the stats were when it stopped working.
40 miner stats at a glance.
M's miner monitor will reboot using SSH

Ah I wasn't aware they had smartphone apps for it as well.  That's great since I can't install teamviewer at my new job...security and all that. pfft!

Oh yeah the smartphone app is the bomb.
Sitting at the doctor's office or waiting for your pizza at the shop you can check things out.

I was about to order the batch 8 but now I am having second thoughts about ROI.
Even with free electricity, the analysis here https://tradeblock.com/bitcoin/mining/a/JzZtkWrbEJb3LeJj28EoCk
shows that I would ROI on August 2016, assuming starting mining on January 2016 and ~5 billion difficulty increase each month (best case scenario). (purchase cost ~$2000, including PSU and customs fees)
Keep in mind that bitcoin halving will be about July 2016.
So why would someone buy a S7?

Speculation on the price of bitcoin rising...if it doubled by the halving, you would probably ROI on it.  Either way it's a gamble.

when I first got mine, I ran thru some numbers with a killawatt:  I run mine at 593.75.  

Code:

freq	GH/S(avg)	HW	watts	w/gh
587.5	4,534.00	0.04%	1159	0.2556
593.75	4,583.53	0.04%	1172	0.2557

If you're getting confused with the different S7 specs...

Going by the list, the odd numbered batches have the best bang for your buck...the even numbered ones are the runts that didn't make proper spec.

I just find the whole S7 batches confusing.  I mean they are taking orders a month ahead.... which I'm not a huge fan of but I can understand it.   I liked when they ship closer to order date.

But the entire changing hashing speed per batch is getting to a almost laughable level.  I mean when S7 starts to be sold to go to second homes (eventually on a lot of them) it's going to be a mess.   I just think resale/buying used is going to be a lot more challenging with so many different specs for the same model miner.
