Topic: [Guide] Dogie's Comprehensive Bitmain AntMiner S2 Setup [HD] - page 15. (Read 63120 times)

Well you have to start somewhere - it's time to stop lurking and pop the first post cherry
Dogie you're the mutts nuts, cheers.. learnt a ton! -  5 s1's down and now 3 s2's on there way. Thanks for the info guys!

Hey InvalidSnack, thanks so much for the detailed post, again I've learned a lot from you. I'm a windoze user so I'm not so linux savvy and your tips help a lot. I'm pretty sure my problem was due to the Miner Config page as you mention, I was using the S1 'trick' of restarting cgminer by clicking save&apply... I guess that was messing things around.

I've not had a chance to fully test your method again, I need to do a little more cgminer research and I'm waiting for a new power board and PSU to be delivered today, so will concentrate on getting that all switched out an running before going back to load-balancing.

I did originally try the method of adding ["balance" : true,] in the cgminer.conf, but that didn't work for me...

Thanks again, you've been very helpful so far

I was worried about the rework, not the cap, look closely at the solder..

Good to know its not a concern in either case.

I tested with a meter.. these caps are sharing common pos/neg.  I also learned something that is going to make fixing power modules on busted frankenjup boards a whole lot easier now. +++

Chips that go missing after a while

It appears to be, yes.  Have they stated what problem these extra caps address?

Isn't this the "fix" that bitmain recently released?

Hmm. That cap looks like its just there to smooth something spikey, and the board could probably run without it anyway. I wouldn't worry about it.

Of course it wouldn't... I was just reading how others corrupted their SD's when they cut power abruptly.

I replaced the PS, then the BBB Board wouldn't get a link light.. Then I replaced the BBB with one of my own from my personal stash.. and it linked up fine.

Then I put back the orig BBB (Because I wouldn't have a use for a partially populated BBB like the one in the miner.)  Luckily, it linked up once again and decided to work.

Anyway.. I'm hashing right along now.

I did notice something else while removing the boards however...  My boards have larger caps on them attached to the surface mount ones... but the solder is connecting to the cap right next to it on a few of them... maybe someone would know if this is a concern.

Google knows as much as we do on this topic, as its not something that we've ever done.

There is no reason the SD card problem would cause a breaker to trip, almost certainly the PSU has blown. You can pick up a cheap tester for $10, or simply order a beastly 1200i. Either way, money is required.

Sorry TracerX and Dogie.

I didn't mean to be rude - point taken though.  Just a bit frustrated with my S2.  I never imagined it would not solo mine. 

I have looked at bitsolo and solopool and am not sure of their validity.  There is nothing stopping the pool controller from keeping the bitcoins and to date, no one has found a block.  Of course, it does support everyone's argument that solo mining is a waste of time but I am perplexed that the cgminer running in the S2 BBB cannot be configured to solo mine my local Bitcoin-Qt.  Bitmain came back to me and said they are currently developing BFGminer to run on the S2.  Maybe we will have better success with that.

Anyways, if anyone is out there solo mining correctly with the S2, I would love to hear from you regarding how you got it configured.

Cheers

Quick tip on network setup - my home wireless network is on a 192.168.0 subnet and the S2 came with a static IP of 192.168.1.99.
If you don't want to mess around with your wireless router and you are on a mac book pro,

Enable the thunderbolt/ethernet port, give it a static IP in the 192.168.1.xx range, cable the mbp and S2 together, pop up a terminal window and do a:


After which you can access the S2 via http or ssh and turn on dhcp without disturbing your main network.

  Got an S2 for a friend, but figured I would hook it up and test everything before taking it to his place.

I hooked it up and configured it .. no problem.. it hashed away happily until the breaker popped.... (Breaker wasn't overloaded)

Long story short...  I reset the breaker, and went back to the miner.  it was dead dark w/ no power.

I disconnected the AC cord replugged it...  I flipped the switch on the back to off unplugged the cord, let it sit for a while.. plugged it back in, flipped the switch.. still dark...  Then I went  removed the ATX jumper on the 24pin connector... tried that in combination with unplugging / replugging, and the switch on to trigger the PSU...

Initially before plugging everything in I checked everything, cards seated, internals looked very sound and everything was connected.

Not to thrilled about the prospects of what else got hurt when this PSU blew... (I assume the PSU is shot, unless anyone has any other ideas.)

Fun fun fun.. from reading the thread it sounds like there is a good chance the SD is corrupted... They should be mounting everything on that card as R/O and only temporarily switching to R/W when changing settings..

Anyway this sucks... if anyone has any idea's I'd love to hear them.  Sounds like I'm stuck getting a spensive as hell PSU before I deliver this puppy.  Has anyone had good luck getting Juan to swap parts out, or maybe give credit so I can pay the difference and get a real PSU that will work for more than 10 minutes.

I just now caught this, Dogie--thanks for the advice.  I'll see what BM suggests next, but I'm also happy to toss my local shop some cash.  I suppose the board warming up could cause it to disconnect again, which would explain why it returned after running for a few hours.

Hey guy, you're not going to get too far here with that attitude--this is Dogie's thread after all, and he's contributed a metric ton of amazingly valuable information and walkthroughs during his tenure here.

Did you google "solo bitcoin pool" yet?  First hit is "http://bitsolo.net/" which looks to do exactly what you want.  There is a thread here regarding it, use the search function to find that.

Please spend some time lurking, and less time making demands of people more patient than yourself. Don't be a dick.

Cheers.

Sorry,  I didn't mean this email to reach "non believers", pool owners, solo pool owners etc, and don't waste my time with your negative attitude.  You go pool mine and I will do what I like.  So back to the question. 

Is there anyone out there who has cracked solo on an S2 or has Bitmain done it again!

It shouldn't be that difficult.  Right!

No, because there is absolutely no reason to solo mine. Use a pool and save yourself the headache.

SOLO MINING

Back to my question if I may.  I think we have had enough about chips.  With the greatest respect. 

I need to know if anyone has been able to solo mine with the S2 and if so, what was the configuration that was imputed into cgminer. 

Nothing I do seems to work.

Anyone?

Dogie's you must know this one?

Ta

The board was originally in slot #3, and I did examine the PCI slots pretty well when I pulled everything out to reseat them the first time.

The x's have returned since I pressed in all the chip and reseated the blade, I'm waiting to hear back from BM regarding the next steps.  I presume we're going to RMA this blade, but I'll let everyone know what the outcome looks like.

Cheers.
