ANTMINER S2 Discussion and Support Thread

[freebit13]

I tried the image from 1l1l11ll1l but for my it did not work.
win32discimager writes for a few seconds but after that i can't read the sd card.

There was also a other image ( updated? ) and that one worked.
It took a few minutes to write that one.

I have just send a email to bitmaintech to ask about this booting problem.
When i have found the problem i will post it in here.

You will probably need to format the SD card properly before writing the image or it might not work (it's partitioned). Download a SDFormatter to format the card and make sure you see the full memory available before writing the image with win32diskimager.

Sounds like you got it working though... if you did, you should make an img of the working card and write it to a spare or at least to disk, to make any future resetting go quicker.

Yes i can see the files on the SD card, both on the card i made with the diskimager and on the original one.
btw, the sd card i used came formatted, i will try SDFormatter tonight to be sure.
Thank's for the advice.

No problem, happy to share the help and info provided by others around here...

Just fyi, it doesn't seem like the card gets completely corrupted, I could also still read it on my pc, it just wouldn't boot the miner. I think it might be corrupting a setting in a config file or boot record somewhere or something that's not very obvious.

Good luck!

Since yesterday apparently.

Edit: be sure to take the diff jump we've just had into consideration: 8,000,872,135.97

who knows amount of each batch S2?

Make sure they are class 10 sd cards. That worked for me.
I had the same problem on my batch 2. Three of them just did not boot when restarted. Even after replacing the sd cards with new ones and the image provided by 1l1l11l1l (thanks!) still no boot. But they were not class 10 cards. I don't know why but as soon as I put in a class 10 card in, with the same image, it worked without a problem and on all three.
Good luck

[whonesta]

I would think the Read/Write speed of the class 10 allows the BB to boot smoothly on the USB 2.0 bus. Hope Bitmaintech is making that change @ the factory, could not be much cost as they can handle bulk purchases of class10 microSD's

[freebit13]

I just had a power outage and it booted up no problem with the card supplied with the machine... go figure

[klondike_bar]

Yes i know, i mined the coins with S1's to buy the S2 on 16-03 for the second batch.
The S1's where great but this 

I hope it's something i can solder back, that won't be any problem for me.
Even if it's a bga or something like that.

On the controller board are 5 led's, only one of them is green.
it's the led with R41D5 marking next to it.
Any thoughts?

look up support for the beaglebone black since that is the control module. its possible you need to swap in a new controller and/or sd card (probably <$50)

The real question is: why should anyone have to swap out anything for an expensive piece of equipment that was obviously poorly tested, and used a shitty microSD card in the first place.

Also stop hiring monkies to throw your packafges onto your planes....do they think there are pilows inside an 18kg box?  what a stupid system, at least work out the delivery part so all the units dont come to people in pieces.

Fragile, or this side up, doesnt mean shit to these carriers, even if they could read them or understaing which way an up arrow is suppposed to go.  Put it in chinese then, but I dont think it will make a difference.  seems like whoever he is using to ship these units is the cheapest carrier he could find as seen in one of theose animated gifs i saw a while back where the monkey is tossing these large heavy boxes carelessly on to the conveyor belt with half of them falling off.

Good work Bitmain, way to kill your entire business operations in one clean sweep.

Maybe you shoulod lower the price again next week and try and get some more suckers to give you money.

why so negative? I understand lots of machines arrived damaged - and i can understand why, particularly if they were shipped on thier sides rather than rightside-up or even upside-down. Hopefully bitmain sees this and is working on it. ever new generation of equipment will have its issues. The first few S1 batches had various issues and non-ideal traits such as the lack of pci-e connectors.

UPS is a reasonable shipping company, not much better or worse than purolator/dhl/fedex/etc. They deliver quickly and at fairly low cost - The S2 just needs an extra layer of protection to keep the boards in place if shipped on its side (such as a cross-bar made of metal instead of foam).

My unit arrived just fine, and is right now hashing at 1100GH

same for my bitfury system a few months ago. the original SD corrupted after a few weeks and i could simply re-image it. however, after a few more it spat errors at me and would not read, format, or reimage. I switched to a new card of the exact same brand/size/speed and the same thing happened after a half-dozen power cycles.  I switched to an 8GB class 10 and no issues ever since

First overnight report of my Batch 3 running on stock settings, stock firmware and stock power supply. Hashing at 1025 to 1080GHs solid, no beeps or loss of power.

Batch 3 S2 replaced 5 BE Blades running on a backplane and heat output is significantly less. Compare that to 50GHs on 5 BE Blades with just about 80% of a S2 power consumption and twice is much heat.

I'm happy with my S2 so far, it is a little loud though but I can live with that.

[smooth]

Has anybody tried write protecting the SD? Don't now if that would help with the corruption, but it might.

thats really good speeds - my batch 2 ran at something like 980GH stock.  did they change something for batch 3, such as a higher frequency or slightly increased voltage?

Just out of curiosity, has anyone purchased the S2's at the $2199 price even?  I'm tempted to if BTC reaches $480+ in the next few days.... thoughts?

$2199?  They are currently listed at $2599.

Alot of people who previously purchased an antminer s1 or s2 got a $400 coupon for a future order.

I bought an s2 recently.  I did not get a coupon.  How do you access to the coupon?

I did--I had a few slots free up at my DC, so in it goes!

[samsonn25]

They should update your account for a coupon, there is some discussion as to how long it takes.
