ANTMINER S3+ Discussion and Support Thread

[ILIKECHEEZ]

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.

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.

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.

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.

NO...don't do it...

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).
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.

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!

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).

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?

[adaseb]

I'm having issues with the wifi. I have the router right next to the miner. It gets 60% signal. But sometimes it drops the signal when mining and start beeping.

And sometimes it sees the networks but fails to connect. Any idea why this is happening? is it because there is no Antenna despite the 60% signal strength?

Can I use the antenna from an old laptop? The connection looks the same.

no probably not.. but just to make the reset button work i updated my s3s to the 12/19 firmware..

it seems to be just as good as the 10/24 one.

There seems to be a new firmware dated January 2015 on the BITMAIN website. Anybody tried that firmware?

Going further than others: Don't bother, you're more likely to end up with 4 fried PSUs and potentially a damaged S3. Even if you could underclock sufficiently you'd still be cross loading 2 PSUs. And even if that wasn't a problem (which it is), you're running PSUs at 24/7 load which they're likely not designed to do. tldr, don't.

As aarons6 said, 12/19 onwards fixes the reset button's functionality. While it won't give you greater hashing power, it is an important bug fix which will give you another layer of protection from bricked units. The last thing you want is an inaccessible unit without the reset button working. 12/19 download link can be found below if you want that one, although there is a newer version on Bitmaintech.com.

Can I get some beta testers for a new S3 firmware please? Download link is here, it *should* be good to go but as you know....

Rolls back to the last good patch in Oct (1024), but fixes voltage adjustment and the important reset button. Hopefully.... let me know.

The s3's antennae connection is quite small, are you sure its the same as your laptops? Can't hurt to give it a try. Lay the antennae so it comes out the little notch the fan's cable sits in, so you can plug in to the controller board but still keep the antennae external.

01/19 disables voltage control on S3s as not all S3s have variable voltage control. Not everyone wants that though, so users currently using 12/19 and 01/19.

Yes, I've tested this on many miners, it works fine and doesn't have the filesystem issue the Oct 24'th firmware has.

[rpandassociates]

Is there any way to tell which S3's have the variable voltage?

my one and only  S3 is a batch 8 everything else i have is S3+
