How do you expect to ssh in with root/root if the password was changed? If root doesn't work for the webui pass it won't work for ssh either(barring some very unusual configuration). You should upgrade the firmware as soon as you are able to login as you are most likely on the very dangerous oct 24th firmware. If you can't get the password from the seller you will have to use a TTL cable to reset/reflash it manually.

Because SSH and webui logins are entirely separate, changing the webui password has no impact on the SSH password. The entire point is that he can't log into the webui and so must use SSH access, else he will likely have to send the controller in.

The Oct 24 firmware is also NOT dangerous, its stable as hell and would be great if it didn't have broken reset button functionality.

Yes the seller finally got back to my with the password and I am greatful because the webui and ssh BOTH didn't work without the password. The units would of been garbage.

And yes I am on Oct 24th firmware. Any benefits to upgrading in terms of power consumption, or hash speed?

No they are not separate, I just verified this again to be sure, changing the webui password changes the ssh password. The Oct 24 firmware uses the wrong(corruption prone) filesystem, normally there is a read/write overlayfs on top of a read only filesystem, however the Oct 24 firmware uses a single read/write filesystem for everything. By not using the overlayfs all changes are permanent which is why the reset button does nothing on the Oct 24 firmware. The reset button clears the overlay filesystem on the normal firmware but since the Oct 24 firmware doesn't have overlayfs it does nothing. Not having the read only filesystem means the chance of flash memory corruption is significantly higher on the Oct 24 firmware which is why one should flash the latest version as soon as possible.

@bitsolutions - thanks for clarifying the reason why the reset button does not funtion on the Oct firmware, it make perfect sense and lays bare the true extent of the danger it poses users. And yes, everybody knows the webui password is the same as the SSH password, but when someone actually steps up and insists otherwise you have to wonder whenther they really know something you missed. Unfortunately (and its not the first time), dogie shoots from the hip and its nothing but his usual waffle (seems like the twat gets paid by the number of posts he makes).

Short question regarding alternative power supply:

I've been changing lights at my home to LEDs. I recovered 6 x AC->DC adapters (12v 60W).
Would it work if I connected each of them to one pair of PCI-e connector pins.
It gives 2 PCI-e connectors, 180W each - at least in theory

I know it would be close to MAX W needed but I intend to under-clock it anyway... so it takes +/- 200W.

In theory that sounds plausible, however, bitmain have advised against mixing / sharing power supplies, and if I get your suggestion correctly, that would indeed be a case of mixing power supplies UNLESS you intend to run each blade on 60W only (12v 5A).

Is this even possible? What is the minimum W per blade? What hash power can be expected then? Forum search is disabled so...

It should be possible, and at that power you may not even need the fans (remember the fans runnig at full pelt will consume that much on their own!). I do not know what the expected hash speed is for that power, but if you want to try it, then start off by reducing the frequency to a very low number and then watch the HW % ..... and keep reducing till you get the least number possible ... and that is the hash speed you can get. I do not think you'll break anything by trying (if you do, its your fault!), but I'd err on not trying simply because the rate is bound to very very low. Not sure whether the much vaunted hardware hack would yield much better results either, at least not running on 60W .... but again, I could be wrong!

If you went ahead with your contraption, you'll need 3 of your adaptors to to populate a 6 pin PCI-E connector (but still be underpowered) for a total of 180W as opposed to the (I think) standard 12v 22A -> 264W.

Anyone here running 2 Antminer S3+ on one Corsair CX750?

I rather not buy a PSU for each and rather underclock the Antminer and run two of them on one PSU.

Yes that's more than enough. CX750s are sturdy as hell.

Quite literally the most durable piece of hardware I have owned. Tried to run on about 5 different trash tier PSUs which could have (and probably did) destroyed the R-box 110g I have running next to it. I highly recommend you get a high amperage PSU, something which is beyond the days of molex. I recommend 48amps. The S3 is a very durable, child proof piece of equipment that is definitely worth the 200 AUD I payed for it.

Hello

I bought a used Antminer S3 but the user and password "root" doesn't work. The previous owner must of changed it.

Anyway to reset it?

Check Dogie's guide at https://bitcointalksearch.org/topic/guide-dogies-comprehensive-bitmain-antminer-s3-setup-hd-702653. There is a reset switch accessible from the front panel, next to the 2 LEDs and Ethernet connector. You power it up, press the reset button through the hole using a paper clip or similar thin object, hold it for 5-10 secs. This will reset it to factory defaults, including the password.

Cheers

Are the lights suppose to change when pressing the button? They all stay lite, like pressing it does nothing.

Yes they are, suggests the unit is on a firmware where the reset button's functionality is broken. While you wait for your seller to reply to your password email, you can SSH and control them from there. This will at least get you up and running.

1) SSH to S5, Login root/root
2) Type "screen -r". Wait for all the messages to go through.
3) Type "P" to enter Pool Management.

How do you expect to ssh in with root/root if the password was changed? If root doesn't work for the webui pass it won't work for ssh either(barring some very unusual configuration). You should upgrade the firmware as soon as you are able to login as you are most likely on the very dangerous oct 24th firmware. If you can't get the password from the seller you will have to use a TTL cable to reset/reflash it manually.

I hope it all works out fine

I flashed the S3+ and it looks different now, I think the voltage wasn't 0000 before and now it is. Another thing I notice, sometimes the Antpool works and other pools don't. Hopefully this fixes it.

PSU is EVGA 1300 G2. Set it to S3 voltage same thing. I am going to flash it with the latest firmware again, and uncheck "save settings". I also have another miner, its the same S3+, same pool, same power supply and it runs fine...
