Just upgraded one of my miners, and get the following error at the top of the miner configuration tab.

New firmware finally    https://bitmaintech.com/support.htm?pid=007201407180243004432lBQW28O0633

S3+, which means S3 B8 and the following batches, has a faster hashing speed, 453Gh/s than the one from the previous batches, which hash at rated 440Gh/s.

Why not run a dedicated 220v line and power your equipment off of that?  You may actually be using MORE power by stepping up the voltage.

B8 and so on has a sticker on it that says S3+.  I'm really unsure prior to b8, it would be nice to know as well.

How can I know what batch I have? Stupid question but I can't find it nowhere.. I bought it second hand.

Yes, I agree.  I pointed that out in a earlier post.

I can't help think that you're losing efficiency by stepping up the voltage.  Transformers aren't very efficient, as quite a bit of power is lost due to heat.

So I did a little testing and want to post the results I got (if anyone wants to put it into an easy to read graph that would be great).
So I measured the voltage out of the wall socket at 118v which goes to my 3,000 watt step up voltage converter/transformer.  Out of the step up converter/transformer it measures 230v.  I've got my APC Smart-UPS 1500 (1,000 watt) sine wave (230v version) connected to that (which I measured only uses 1 to 2 watts when the battery is full).  Also have a 5 port switch that measures about 1 watt of consumption at idle connected.  The ThorTech Thunderbolt Plus 1200 watt power supply is connected to that and the pair of AntMiner S3+ are connected to that (the display is showing that the power supply is running at a 92.77% efficiency).  So the measurements on efficiency and power are for the pair of (batch eight) S3+'s working in pair and mining for at least 5 minutes at each speed before the measurements were taken (225M and 237.5M were taken after 1 hour).  Note that the case the AntMiners are in has 6 additional 120mm case fans as well as a fan controller (at about 2w per fan, that's 12w plus whatever the fan controller uses that should be deducted from the rating below from the pair of S3+'s).  The wattage measurements fluctuate so I took the closest average.

Looks like I'm going to underclock a little 3 S3+'s down to S3 default speed of 218.75M on a EVGA 1300 watt G2 power supply for my next rig for about 1,050 watts at the power supply.
Here's a little odd fact I found out this weekend, when I set up a pair of S3+'s (at 237.5M for the pair) with a Corsair AX1500i Titanium power supply on the same power set up as above and only 4 smaller case fans, the wattage was about 20 watts MORE.  This shouldn't be as the power supply is Titanium rated and set up is closer to the 50% load rating.

Thanks! Feel kinda stupid, I didn't even notice they said S3+ in the title. DOH!!

You can use 1 per miner purchase and the type they can be applied to is written in the title/name of the coupon.
If you wish to sell them please use the correct marketplace forum.

I hate to ask this, but I can't find the answer anywhere. These coupons, I have 20, can I only use 1 per new miner purchased or can I apply multiples to a single miner purchase? Also, are they restricted to which miner I can apply them to?

Thank you! Explains a lot! I will now be able to fix it!

There's another computer on that network with the same IP address. Did you set it to a static IP address or dhcp? You'll have to either contact your host and give them your MAC address and IP, and ask them to find the conflict, or do your best to change your IP to something else that's not in use. If you're using dhcp, then release/renewing your lease may fix it, but ideally you shouldn't have IP conflicts on your network.

Hello,

I'm having trouble connecting to 1 AntMiner with ssh (I can't connect directly to the web interface because it is in a server room somewhere else).
Whenever I try to connect to the miner this error pops up:

I've tried to delete the .ssh/known_hosts file several times now. But the error keeps coming back. Also I noticed that my hashrate dropped on the pool I'm mining on. Anyone else had this issue before?

I've managed to reset the firmware on the antminer, but now it constantly says the password is incorrect. Used both my custom pw and default password

I used
(the directory "oldcgminer" was created earlier to hold previous versions)
hint to reduce typing errors:  (works on Putty with Windows) copy the text that you want to enter, then mouse-left-click in the Putty window to define the insertion point, right-click to paste the text.

Your procedure looks ok as well.

Cheers

is it correct commands to update ?

SSH into the S3 and login
cd /usr/bin
mv cgminer cgminer.bak
wget http://ck.kolivas.org/apps/cgminer/antminer/s3/4.6.1-141020/cgminer
chmod +x cgminer
Reboot


thanks

Any discounts on shipping?  Shipping is about 30% of the order, if you are only buying 2.

Shut it down and unplug supply and ethernet, let sit a few minutes, replace cables and fire up.

If still doing this then try running nmap from a linux machine and see what ports are open on the device.
