ANTMINER S2 Discussion and Support Thread

[ElGabo]

Reseated all the boards, and rerouted some of the wires and taped down the fan wires (they are a bit close to the boards for my taste). Booted up. First boot with full fans is LOUD. Just plugged in my settings and is rebooting now. I have some pictures and a video of the first Boot with full fans I can upload in a bit. I lack Kill-a-watt or a sound leveler so I can't help out with those.

The main fans are 4X 120x38mm though. They are Jiang Shan Lai (JSL) DC Brushless Model JDH1238B. 12V - 1A. 

Thanks for the info!

Thanks klondike_bar too!

I have most of my ants installed this: http://www.soselectronic.com/?str=371&artnum=69472&name=sunon-pmd1212pmb1-a-pmd1212pmb1-a-2-gn

No pwm, nothing, but rock solid. (And loud but for me doesn't matter)

Who wants to see the difference between the Bitmain BBB and the stock BBB?


{pics snipped}

Thanks 1l1l11ll1l,

the small differences make me think the S2 BBB is a chinese knockoff clone..

Noticed that too... must be knockoff version for sure

You guys realize that the BBB is an open source design right?

Yes...it is an open source...but Chinese engineering is giving it a "kick"...for sure...

Finally up and running. Totally forgot about fish-eye on my GoPro so my pictures aren't great. Do have video of the full fan on first boot if I can slim the size down for upload.


The last thing keeping me from hashing was changing the DNS server from 192.168.1.1 to 8.8.8.8. The router here blows some PoS TimeWarner All in one rental, but its also set to the same Google Public DNS so I don't know why that was preventing me from hashing.

Other than that and reseating the whole thing to double check, I didn't have much problems. Though on reboot you have to wait for over a minute, due to protection in the PSU I'm pretty sure. Because I turned it off and 10s later it wouldn't turn back on till i unplugged and let it sit for a couple minutes.

My only question is what's the safe temperature of these things. Mine has settled at 60C over the last 15 minutes and appears to be holding steady.


The S2 is LOUD though...I don't recommend sleeping or generally being in the same room unless you like fan noise for ambiance.

I think set it to shut-down when it reaches 80C... Guessing it can run up to 79C without any issues

Yeah, seeing how there's now an auto-shutdown at 80C option...but we've all been babying the S1s at 50C and under so *shrug* Its hodling at 60C for now. I'm sure my room will be a sauna later.

EDIT- type no>now

Totally meant now not no. Sorry


Also. I'm not sure which board location coresponds to Chain 1, but its clearly running 7-9C hotter than the rest on my unit.

Lot's of discards. Never seen this number so high an any ant (relative to hashrate)

My S2 is working now!!

I noticed a chunk of glue(?) in the slot with the main card.  I removed it and reseated the card and now everything works!

The two Ethernet lights on the outside of the S2 and the two on my router are always off, when it is powered on.

Do you mean the internal Ethernet cable that is attached to the main (middle) board?

8 of the 11 cards were not seated properly.  

However, after re-seating, there is still no display and no lights on my router from the Ethernet connection.

I've already done a second pass at re-seating, and the internal Ethernet and ribbon cable are connected fine...any other ideas?

Since the display isn't lit, does that suggest a power terminal isn't connected or that the main board is fried?  

At least the fans make an impressive sound.  

I got my S2 today.  

However, the display does not light up.  Although the fans do turn on and I can see red lights inside it.  

Also, the Ethernet is not detected by my router.

So the consensus is that I should open it up and see if anything needs to be reseated?  Will this void the warranty?

Thanks!

Check that all cards and cables are seated properly. 

check lights on controller's ethernet port

Just received my lone S2. I can confirm that the straps on the box do nothing but entice the driver to sling it around 1-handedly as I watched the man grab it and bounce it off the 2-steps of his truck. The package is well worn around the edges for just 3-day trip and has nice rip into the side. Unboxing now. Bad note, I can hear things rolling around inside the box already.

Do any of the deliveries have a fragile sticker on the box at all? It doesn't sound like they're being handled appropriately.

If anyone is wondering, I'm seeing 10A @ 208V for two S2 units on my PDU.

What PDU are you using?

Quick Q.  Did you guys who got B1 get a shipping notice from Bitmain or was it marked shipped on the website?  Any info would be appreciated, thanks!

I have some glue on mine too, but it didn't interfere, and there appears to be something under the glue as well. By the edge of the tab, it looks like its been partially cracked or added after the fact or something. The pictures didn't turn out great but you can at least see the glue on both sides. I'll take it out and snap another later tonight, but it works solidly so I'm going to ignore it for now.

As for the fragile sticker, the only thing on the box besides the tracking/shipping label is a big blue sticker with a black D on it. Which I'm guessing is for http://en.wikipedia.org/wiki/ORM-D that? but it just a D and nothing else.

BITMAIN: please put some Fragile stickers on the batch 2 orders before you ship them... they are obviously not as tough as the antminers.

Many thanks!

It's just a rework of the board.  If you look closely, a trace has been cut and a jumper installed.  The hot glue is there to help keep the wire down and try to keep other stuff from snagging on the jumper wire.

Has anyone tried the new firmware, yet?  Any idea what it's supposed to fix?

Well I for one hope it fixes the reject rate 53% pool rej

Its bad enough paid a premium just to have to put it back together like a avalon clone after shipment.....

Tweaks to get it running after painstakingly putting it back together havent bothered to email bitmain they havent responded to me after they fubared a shipment back in february

Maybe their last harrah and pulling out of the market ....used power supply from their farm no less.


What a joke should have gone Dragon for 30% less at least I get paid to do all this extra shit

When you overpay for a minor every hash in first two weeks counts losing a ton of hashing like the shipment fubar in feb glad some of you have had good customer service perhaps I was too professional with them maybe I should have yelled like a little bitach

How did everyone change their IP for cgminer? I've edited the IP and gateway settings, and that seems to be fine.

cgminer still appears to be trying to communicate with 192.168.1.1 though, and I can't seem to find where to set that from the command line.
