Just fired up an S3+ today which came with the antMiner_S320141126.bin and as prior posts indicate it would stop hashing (~47Gh) after a few hours. I thought it was bad hardware, but I had also upgraded 5 other S3 & S3+ today to the same firmware and they each began doing the same thing.

Uploaded antMiner_S320141024.bin and things are pretty normal.

You forgot having to peel that nasty plastic wrap off each one

I've got 4x AM-V1 which I stack. And then 2x AM-V2 which I stack. The V2 board and casing is smaller than the V1 which makes stacking of V1 and V2 not easy-peasy.

I'm using the Dell P/S sold by minersource for all of them (2x per 1.2TH). I tape the two supplies together with aluminum tape (for ductwork) and then I safety wire them to the stack. I pop-rivet the miners to stack.

It requires one raspberry pi per 8 boards. Too bad, I was planning on running a floor-to-ceiling stack with one pi LOL.

With the Dells it is drawing 1450W at the wall per 1.2TH. These things run and run. I am constantly dicking with my other miners for one reason or another and these btcgarden always sit at a consistent 1240TH. Temperature monitoring and better power efficiency would be welcome though. I've got a blower fan behind the stack.

Having the metering display is kinda nice I have to admit. One feature which would be nice is ability to cycle power remotely. I see that some of them have a serial port setup for that. In fact there are some of these Avocent Cyclades on ebay I saw referenced in another thread. I've not tried though.

Also, hasn't been mentioned but you might just get an electrician to do some work, adding receptacles and making cords. All of the connectors and wall receptacles can be found locally and an electrician doesn't usually charge that much in the scheme of things.

I would also recommend a PDU if you go to 240V. It's super clean compared to a ratsnest of 120V. I have a 14-30 dryer socket (30A 240V service) and I made a 12awg cord going to two L6-20R sockets. The PDU comes with an L6-20P plug so it is just plug & play from there.

A couple of these (240V 20A): http://www.amazon.com/gp/product/B0052NM4JA/ref=oh_aui_detailpage_o06_s01?ie=UTF8&psc=1
Lots of these: http://www.amazon.com/gp/product/B006ZB304G/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

Keep in mind that most equipment is 80% of their listed current. 20A PDU would be 16A continuous, and 30A PDU would be 24A continuous. That's why I opted to go with multiple cheaper 20A PDU rather than a single 30A PDU.

BTW I have that EVGA 1300 G2 and it runs fine @ 240V.

Some information I use on my S2.. I've only had mine for a few weeks so I am not versed in recovery methods yet. Please use caution etc.

Persistent files go into /config where you will find shadow (a copy of /etc/passwd), asic-freq.config (your under/over clocking values), lighttpd-htdigest.user (contains web password).

After setting my root password with standard passwd command. Testing it etc. Then I copy /etc/shadow over to /config/shadow in preparation for saving.

The web password seems to set properly for me using the web console. However, if you have trouble you can look at the /www/pages/cgi-bin/passwd.cgi and see how it is storing the web password. It simply goes into /config/lighttpd-htdigest.user as an md5 hash.

echo -n 'root:antMiner Configuration:your_password' | md5sum | cut -b -32

And that should show you the hash value to use in the lighttpd-htdigest.user file on that 'root:antMiner Configuration' key.

Not sure if you'd have to make the change to /etc/lighttpd-htdigest.user as well to test the changes.

Once you've tested all the changes and they work ok, the trick to burn the configuration is to use the web console Miner Configuration tab and hit the Save & Apply button.
