ANTMINER S2 Discussion and Support Thread

[smooth]

I had a similar issue with S2 power supply just shutting down at will every few hours or so.  After replacing the *power cord* with a thicker heavier duty one, it has not yet shutdown after running for 24+ hours.

I would guess this is a common problem. Since they don't ship with correct power cords for the US (and ?), people will use whatever they have around, which often will not be a 1+ KW power cord.

My issue seem to have been related to the PSU as this miner that had issues draws a little more power then my first one.
With the new enermax 1350W platimax it hasn't turned off yet and running ok with 10 boards
Shame I had to spend 250Euros to get fix my miner, while the first batch of S2 got a platimax and we got cheaped out with a gold 1000W power supply.
If they would have gone with cheaper power supplies they should have gone with a higher powered one .. just my 2 cents of thought.

I hear you.  My next plan was to replace the power supply, which I may still need to do depending on how my "fix" holds up.  Got spoiled with the S1.  But still have faith in Bitmain.  The S2 is a little rough around the edges but they will improve it over time.

Could always go to your local garden shop and buy one for a 1000w HPS ballast.

Exactly my thought, and exactly what I did.  I just picked up the nearest power cord without thinking too much about it (until I started having power supply issues that is).  I'd encourage S2 owners to try the cheaper solution first before replacing the entire power supply.  After all, you can get a heavy duty power cord for almost nothing.

PSU is now officially DEAD....

Emailing Bitmain AGAIN....

looks like Bitmain should've listened to all the numerous shouts made here about properly sizing the psu, or atleast gave the option of no psu and/or better ventilated the unit.

He did - on batch 3....

and apparently the problems im having are down to my network.

the same network thats perfectly fine for 6 S1s, 2 avalons, and 2 jupiters...


@hurricane dave, these Enermax Revolution 87+ PSUs dont even have a fuse in the plug...

Have you taken out all the blades?

Also I had to pull out the BBB and unplug the net connector and pull the SD in and out to get mine up and running.....can see why but it worked

[sbfree]

just as an FYI, just because the blade is blinking doesn't mean it is working (hint for jenlin). I actually had a blade/hashboard that lit up/blinked and got warm, almost hot to the touch as though it was working, but it would not should up on the WebGui, so I swapped it to another slot, same thing, then tried it on another good machine with a bigger PSU, same thing. It would cause slight more power draw, get hot and blink but was not hashing.

SO now BITMAIN is on the RMA. It seems UPS had trouble delivering it in China, but Bitmain is on it lightning fast. If they get it tomorrow, my replacement might ship out tomorrow and be here Wednesday/Thursday if I am lucky.

Go Bitmain.

Received my S2 a few days ago and don't have any problems. I guess I'm lucky or something.

Do they have any plans for batch3 at all?

I love that Bitmain actually ships their products... you know... when they say they are going to.  I just wish they interacted with the community a bit more... its a shame .

[mdopro1]

I'm just getting tired of refreshing their website whenever I can several times a day. I know B3 will last 5 minutes and I will miss out.

They used to be more involved with the forum. It seems to be the pattern for every hardware developer... post a lot on the forum and then slowly disappear when things get complicated... KNC, the Bitfury guys, HF, etc. Heck, even going back to Avalon, BFL and ASICMiner. Spondoolies are still in their honeymoon phase and post almost every day. Let's watch and see if that changes too.

i noticed that too..
I wonder who's next to have their "honeymoon" phase as you say lol..
I'm putting my money on Nonce-tech

Let me explain to the noobs.

Bitmain S2's PSU are for Chinese market.... which mean its supposed to run on 240v. So the power cable gauge is higher (thinner wires).

For 110-120v, you need at least 14awg.... , 16awg is pushing it. And i believe 1000w on 240v only needs 18awg (which seems like the included cable).

Unless they price it well below $3/GHs, they're not sold out ever

have this company gone tits-up yet?

You're better than this!  Trying to get more people into your group buy perhaps?

I'm somewhat stunned by this also.

while i am genuinely interested in the spondoolie rigs, the marketing strategies are quite unsettling.

it was a legitimate question!!!???
and since when was I on the payroll for spondoolies? fuck sake you lot really are hard at it with the conspiracy theories.
here's what I see,,, a shit load of rigs that don't work properly. I remember a company called Lada that used to make cars...

nevermind.

ADD: I think you'll find I run enough businesses to be bothered about marketing ASICS;

www.rgspix.com
www.stockpix.org
www.stockpix.eu
www.thescribe.eu

and I also work in a local care home as activities co-ordinator.
i'm just a forum member like the rest of you!

Lada is still tthe best to have fun on gravel.

[raskul]

raskul bruv, i think your mixing up posts.

quite obviously they havent gone 'tits up' just yet.

like i said, i am genuinely interested in spondoolie rigs but you must be aware of peoples concerns especially wrt company accountability and the immense amount of difficulty increases already upon us.

and i really enjoyed my lada back in the day.

it was bought from stock with no pre-order bullshit , no excuses and legal immunity for the seller if it arrived late/never or blew up etc.

you seem a sensible chap, how about a bit of balance?

sorry, i'll do my best mate, but... aye you are probably right, thing is, i do get concerned about folks getting 3rd rate equipment and as I said before (without any ulterior motive) i was pleased when you managed to get hashing with your S2. I admit, perhaps i've been a bit gung ho in showing off my new rig and i'll stop now. I do, for assurance sake, however, buy my mining gear from as much of a spread of manufacturers as I can, although my old 130nm stuff is now switched off and in a box, i still run my BFL pair and my Block Erupter cubes... so i'm not exclusive to one company. I like to look at my rig and see a mix-mash of different bits, it's all part of the fun, right?

And I bought Skoda, so i suppose i've got no place to take the piss.  
sorry if my post seemed untoward, i'll chill. peace.

ADD: to keep on topic, i still rate the S1's - although i don't have one, i have a mate who does and from what i seen, was quite impressed.

[smooth]

I got hashing (right at 1.0 TH) with the complex and time consuming process of plugging it and and entering the pool configuration.

There are definitely some design problems here, and I've said so on this thread, but at the same time, I think you have a lot of squeaky wheels, and some unknown, but I suspect quite large, number of people who perfectly satisfied with the product and therefore relatively silent.
