ANTMINER S2 Discussion and Support Thread

[Cheeseater]

29 out of 30 blades is not bad...time to contact bitmain and see what they can do for me. I am just glad it wasn't the mainboard.

Dam that was a quick reply...I LOVE BITMAIN.
They are going to RMA it. Kinda wish they would let me pay for the blade/hashboard and send it to me while I send this one back. Then they cuold refund me once they have the bad one. but alas I am happy that they have responded so quickly. Thanks again BITMAIN.

I love them too, but RMA process is a nightmare. I received an S1 with a bad control board paid the entire cost of a new S1 and they shipped the board... thanks. Shipped the board back UPS at a cost of $129 because they had to receive it within 7 days of me getting the replacement board. Long story short miner no mine for 3 weeks, .93 BTC for board, $129 for shipping board back, and still no refund or compensation. Did get an email 4 days ago from BITMAIN stating not to worry all will be good

One bad out of twenty is pretty damn good and I'll still buy from them but damn take care of my RMA! And I still want a T-shirt  

[CroverNo]

Correct me if I am wrong but I'm pretty sure Bitmain said that they had resolved the issue with shipping the units in batch 2 to make them more secure with lock in clips ?

From what I can see so far this is not the case 

Hopefully Bitmain can make an official post as the RMA mumbers must be costing them a fortune!

Hopefully mine arrive okay and safe but I fear the worst with the delays 

[wpgdeez]

Bitmain should ship the modules in a separate box with instructions for the customer to plug them in. The fit between the blade and the PCI slot is obviously not snug enough. Do they not screw down like a video card would in a case?

[googlemaster1]

The only problem I had with mine is a bunch of loose cables and the damn case would NOT come off.  I had a couple screws that were being stubborn, so I just used the back of a hammer to pull through the screws on the two that wouldn't come up.

Once I got it open, the only problem was a bunch of unplugged cables, which is really freaking weird.  All the boards were perfectly aligned, which was a big surprise for me.  Once I got the ribbon cable plugged back in on the controller my network started to work and configuration was a breeze.  I was sitting below 1000 gh/s for a while (like 967) which really pissed me off, but i went away and came back and settled around 1010 gh/s.

All and all I'm pretty happy.  The case looked like someone hit the top of it with a fucking hammer.  Aside from that though, it hashes perfectly, so that is really all I care about.

[philipma1957]

so these are not really ready for prime time.

I am still better off running my 5 s-1's at 200gh each.

oh well I will wait .  in the meantime I ordered this psu on account.

Anyone have any luck with overclocking? I've been running 5 s2's at 225MHZ (EVGA 1300W PSUs) for 24HRs. Here's the 12HR average for 5 machines which, at the console, report 1150GH/s each.

[edgar]

Just finished surgery on  batch 2 S2's after receiving them today. All is well and they are all hashing at around 1 TH/s. As others have mentioned before, you will need to open the unit to reseat some of the cards.


Are these upgradable considering the relatively  modular design ? The PSU can be upgraded and the "wafers" can be removed.  Your thoughts ?

LOL what? you know what wafer means in semiconductor?

I hope you meant "modules"

LOL what? you know what 'are these upgradable considering the relatively modular design' means?

I guess you meant "sorry bud, im clueless but i can mug you off for no apparent reason"

Hey dumbass, why even open your mouth and confirm you're retarded?

Those module boards should NEVEREVEREVEREVEREVEREVER be called wafers. It makes me cry!!



Now go crawl back to whatever filthy hole you came from.  Or I'll cry some more and get abusive...

Awesome attitude shit-cunt!

Is that how your parents taught you to talk to people?

Either answer the question posed or keep your shit to yourself, its rare that anyone wishes to be abused by anonfags over some weak BS.

And by the way, i dont open my mouth to type (or think, or read, or breath) - i know some folks who do, obviously you're one of those!

As if you're one to talk about attitude and politeness when talking to others.  On another note, who gives a shit, quit cluttering the thread.

[phroyRov6]

My S2 was running fine overnight since last evening. Suddenly stopped hashing (based on pool stats).
Will have to investigate when I come back from work.

Anyone else had a similar experience?

[sbfree]

no they don't.....2 came in pretty good, just had to push down to seat the cards/blades...the 3rd came in like the pics above, looked like it exploded. At first I thought I had a bad mainboard but in the end it is a bad blade/module so off it goes to RMA. But now it seems I have a PSU shutting down....

I'm working on this.

Have to calculate the clock settings.

You've tried it with the stock setting in asic-freq for 225M?

I think those numbers are no good.

Haha, fair point.

But fk you too!

i wont be abused by some know-nothing-know-it-all mouth breather without fighting my corner.

the guy was asking for rhetorical advice/hopes for future upgrade boards and all he got was 'know-nothing-know-it-all mouth breather' BullShit...

Should we allow these muppets to ruin every thread they think is theirs?

Probably not, eh...


@ sbfree - What are your ambient temps?

78-80 degress, cali is getting warm....all 3 are running, 2 fully, 1 with only 9 blades and Without the provide PSU as it shuts down, max temp of all units is 58C as usual on blade 1

The PSU shut down after 8hrs or so....I removed in put in a 1200W temp PSU....checked the bad PSU would power up, but now that its cooled it powers up.

Batch 2 seems to get better power consumption.

It was hot in New Jersey over the weekend 84 f.  I had to run my central air or my mining garage would over heat.  I decided to sell 2 s-1s'   and now it is back down to 40 f.  LOL.

I am looking to order a 1th machine I am biding my time to decide what to get.

[jelin1984]

What better have batch 2
Better hashing speed?
Or better watt per wall?

[sbfree]

edgar, i think these chips can handle 80C (but don't  take my word for it ), like a GPU and other ASICs, although that is now on the warm side....so i think you're ok for now.

I am using a 1200W Raidmax open case for now, and actually the fully enclosed unit is running the coolest....I imagine better airflow, not sure of the draw at the wall, I'll check that later and it is 6 PCIe connections.

I will test the stock PSU one more time, but I am sure its a bad one since the other 2 w/ stock PSUs are running fine showing 980GH/s each at the pool.

[smooth]

so these are not really ready for prime time.

Yeah, they need to improve the case design so it can withstand shipping without boards coming apart and cables coming loose.

These problems are too common to be attributed to "mishandling" during shipment. It is a design flaw. They need brackets and probably better connectors on the cables.

That said, no problems here.

[dalenorman2005]

So i've had my three batch 1 S2's running for over a week now, and have some observations:

Stable. 
when they run, they run.  have not had the need to babysit them.

corrupt SD cards. 
twice now, i've gotten corruption on the SD card on one machine or another.  If there's a power cut, i cross my fingers and hope for the best.  chances are, at least one machine will need it's SD card removed and re-imaged.  Big thanks to the guy who posted a link in this thread to a copy of his SD card.  Although Bitmaintech has now posted updates to the firmware, they are in the format needed to update via the web gui - not directly image the SD card.

this problem is particularly concerning as there is no "shutdown" option in the GUI or button on the case.  just the power switch.  So each time you shut it off, you have a 50/50 change of buggering the software.... yikes.

can't power on.
This problem is unrelated to the software issue described above.  for some reason, there's some kind built-in protection in the power supply that prevents it from being turned off and on again quickly.  i guess this is a good thing, except it give the impression that the thing is dead until you leave it be for at least 15 minutes between powering off and on again.   Have not found any work-around.  Now that i've learned this, i know to expect it, but to the uninitiated it is a temporarily heartbreaker.

The Beagle Bone has that corruption issue, not sure why but it happened to me in the past so I knew right away to have an extra SD Card ready.

The 1000W Platimax would go into safety mode on my 15AMP circuits and it does take 3-4 minutes to reset by itself, I fixed that by replacing it with a 1350W Platimax & it runs on the 20AMP line now.
