ANTMINER S2 Discussion and Support Thread

[edgar]

Both good posts, and i appreciate the info regarding other suppliers/manufacturers.

S1's are ok, if a bit variable - i have 3-4 different modles and they all behave ever so slightly differently.

now my S2 is running i really like it. Bitmain has claimed he will send a replacement PSU tomorrow 'powerful enough for an S2'

but in all frankness, NONE of these rigs are going to make anyone 'much' of a profit, even if they DO ship from stock immediately.

those days are gone, and the very few who did well back then must be in hysterics watching us muppets chasing chump change.

let us not all devour each other & hope for the best.

I remain on the fence wrt spondoolies, with much interest - but who wouldn't love 5TH right now??

10TH today are needed for 'just' 1BTC per day...

August is a couple of lifetimes away wrt looming difficulty & my breakers are almost fkn glowing!

For what it´s worth, you can get 1th bitmine clones delivered within 3 days for 2400 to 2500, same power efficiency as S2.

Did you guys receive them just now? "shipping before 10th April...."?

If so, the pricetag wasn´t justified at all....

Mine sort-of "shipped" on the 10th and I received it on the 15th. It was hashing within an hour.

BTW, the pricetag in BTC depended a lot on when you ordered it, because the BTC exchange rate was dropping pretty fast during the sales period and the sales price was fixed in dollars. I ordered early and paid 5.6 BTC. Later orders paid a lot more.

i'm shifting everything from the office room into my old man's garage today, i guess part of the fun is drilling holes in walls, setting up rig space and configuring stuff, but we all know that mining has moved to a different fork (see what I did there?) altogether now but I don't mind staying part of the game... i rant on about it being just a hobby but when these rigs are draining way to much power than is feasible in a short term environment, i know it's time to switch off. i've a box-full of 130nm that i intend to keep, just to heat different parts of my home in the winter-time - gets bloody cold here. good thing is my mum has now caught the bug and wants to start mining (we did a 3-way split on a babyjet+upgrade last year - still to be delivered/refunded/acknowledgement that we even exist), so while i'm moving stuff today, i'll probably get her to click my referral links and bump up the TH/s's   what the heck - i'll pay her my referral fees to cover her first few month electric. If i can get my dad interested, we could just fill the garage with rigging (ahem- from a range of hardware manufacturers)

Hi,

Is anyone having issues accessing S2 units through a VPN?

I have two installations behind two different VPNs and cannot access any S2. Other machines behind the VPN are accessible and the machines are accessible when I am directly connected to the network. These are batch 1 and batch 2 machines.

Cheers

labeled for shipping on the 10th but didnt actually begin shipping until the 13th, arrived on the 17th & took just over a day to sort out the few issues.

over-priced & poor logistics & dying/dead PSU & dodgy internal ether 'pigtail' all add up to yet another sub-par delivery that could easily have shipped from stock and there was NO NEED for claiming it would ship by the 10th other than to justify the price tag.

Especially when there is already a 3rd incarnation of the rig (with the PSU inlet facing the outside with a nice big hole in the side) unlike mine which has the PSU hanging out the arse like a grotty hemorrhoid.

Still wondering why i can only access certain areas of the GUI while mining.... Miner Config & Miner Status remain unattainable.

* * *UK Customs charge = £145 * * * (Cheaper than expected)

1. Unpacked my S2, removed cover, reseated all cards most of which had disengaged from there ports.

2. Using my own power cable plugged unit in.

3. Connected unit to router.

4. Powered unit on.

5. No display showing.

6. Checked ribbon cable, main control card loose still. Reseated.

7. Switched unit back on.

8. Display now shows current IP address e.c.t

9. Configured miner pools as required.

10. All Ok.

11. 4 days later, temp never exceeded 51 degrees.
     4 day average @ 1030GH/S

Total setup time: 30 minutes.
Downtime in 96 hours: 0 minutes.

So all good in my S2 experience so far!

My PSU is pulling around 920Watts from the wall.

My recommendation.. DON'T power off your miner once it's running.
Damn thing gives you headaches to get it working again once powered off.
This is mainly because all transistors need to be clear of any power that's left through the system.
Even my platimax PSU had issues it needed clearing of the remaining power left in the capacitors  to get it working again.
It's really a shame they designed the power in such way and not connect the power to the board directly so the board would regulate the power and capacitors.
It cost me another hour to get things working again only to find the miner turn off again, so swapping modules around again to get things working.
With this I need to wait and wait for all power to drain from the power from the machine and try again 
This happened when I tried to tune the miner with frequency setting 250, so my guess is tuning this system will only take more of your mining time then you want.

that would not be a good idea - PSU manufacturers have decades of experience in designing high-efficiency components. if bitmain atempted its own 120/12V regulators it would almost certianly result in efficiency well under 80% (try 60-70%)

Thanks, now I know it's something I can try to rectify, appreciate it.

Come back from easter break to find one machine completely unresponsive. I've isolated the PSU, given it an hour or so with no power, checked the paper clip short, still no luck. I seem to remember someone saying to drain the PSU you short the two power pins out, still nothing.

I have a Corsair CX750M and a FSP 750 Gold, can I just plug these into the PCI-e power sockets and combine them or does it just not work that way?

Another machine was running at 50% hashing with lots of x hardware errors but a shutdown has that back up and running stable.

[1l1l11ll1l]

After having no setup issues and running great for the last couple of weeks, I woke up this morning to find my batch 1 AntMiner S2 not hashing, fans going full speed, panel dim and the red light solid. Recalling that others here have had the same issue, I went back and skimmed over the previous posts and found that the likely issue was probably a corrupt SD card. That was indeed the case, as I am now back up and running, and I figure the problem started when a brief power outage occurred here this morning. Thought I would briefly summarize what I did to recover, which may be of special interest to those folks using a Mac to write to their SD cards:

- ran to the store and bought a 4gb Sandisk microSD card. They didn't have any class 10 cards, only class 4, but it seems to work (ordered a couple class 10s from Amazon for backup).
- Downloaded onto my MacBook the latest firmware from the bitmaintech website, as well as the SD card image from https://dl.dropboxusercontent.com/u/16075357/bitmain.img.zip (thanks 1l1l11ll1l)
- put the new microSD card in the adapter, shoved it into my MacBook, read through the guide at http://elinux.org/RPi_Easy_SD_Card_Setup, and then ran these commands in Terminal:
   cd Desktop (my bitmain.img was on the desktop)
   diskutil list (to find the disk name of SD card, mine was disk2, so replace disk2 below with what yours is)
   diskutil unmountDisk /dev/disk2
   sudo dd bs=1m if=bitmain.img of=/dev/disk2 (this took 30 minutes to complete)
- once SD card was ready, I opened up the AntMiner, pulled out the BeagleBone card, swapped SD cards and reassembled
- powered up, and it started hashing again. Connected to the miner from the browser, uploaded the latest firmware, changed to point to my pool, and everything was golden.

Much thanks to all of previous posters that talked about this issue, as your help got me back up in hours as opposed to days.

Glad to help!

Still waiting to hear positive confirmation from the Bitmain engineer/s regarding 2x 700-750w PSUs.

2 x 650/750W server style PSU should be ideal...even redundant...and cheaper too...IMHO...

But this is their product/design...

Its not redundant unless the device can run with one PSU working. That would be 2x 1000W+
