Bitmain - Every hour we're down we're losing money.  What is your ETA on getting us the new firmware???

Based on their previous record - about 7+ weeks........

Is that before or after the the 2 months of sending screenshots to convince them there is an issue?

Who are you? Your number is plastered all of the internet for all manner of things.

That phone number and the address belongs to Bitmain's support @ North America . The reason I know is because I had to RMA a s3+ blade from my batch 9 since it stopped working shortly after I received the miner.
Nonetheless , my RMA process went very smooth since I got the replacement blade at my door in less than 2 Days.  I would recommend anybody needs RMA support call that phone number (they also have one for EU but I can't remember the number) you'll get much quicker result instead of trying to contact bitmain on this forum.

Well, I'd rather have a buggy unit ASAP as opposed to having them test them and drive the difficulty up in the process before I get my miners. To be honest when it works it works very well. Happy to have it so quickly after ordering.

Well, I'm happy you're happy  

Myself, for that price, I'd prefer not to be treated like a guinea pig beta tester on a miner that might work on certain pools if I'm lucky while hoping my hash power is going where it's supposed to go......

Hindsight and all that jazz. Here's hoping by the time/if you decide to buy one you'll get a bug free miner.

What? no dumb fck. lots of ppl here already warned you. But you're too stupid to see.... dont call it hindsight, retard.

If you're too dumb to understand what we're talking about, you should refrain from posting.

[xstr8guy]

I held back because of price but that looks as if it is the least of the S4's problems. Hope for Bitmain these are just isolated incidents,

Same here. I have never had an issue with any of my old S1's or current S3's. Something about Bitmain making big miners seems to mess everything up.

At least the S2's worked.......once you'd re-assembled them.......sort of........

And replaced the underpowered, crappy Enermax PSU with a good one.

Would you happen to have access to a beta of the upcoming firmware?

Is there a Dogie's miner setup guide for the S4?

[dkaufman]

Does anyone know what username and password could I use for SSH access to S4? The device is freezed but SSH is live.
Thx.

ssh username is root, and the password for the S4 is "admin"

I've been ssh'ed into mine.  Contemplating upgrading cgminer myself... Dare I?  The author posted an ant miner-patched version and instructions (well, for the S3 I think)...

I suck at Linux, but I'd like to ssh into a few of my miners to see what's going on behind the curtains. How would I go about seeing cgminer once I'm connected?

Edit: Gave screen -r a try and that worked. Any other tricks I should know? Tried the same on an Innosilicon A2 Terminator, but it isn't the right command.

If you are on windows, you can use a free SSH via GUI

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Type in the IP address of your Antminer, then username root, password admin

*Please BE VERY CAREFUL as you will have full ROOT access and any unintended modification may make the miner not hash.  You can always restore the changes by re-imaging the microSD card with the factory stock image on http://www.bitmaintech.com support page.

Too bad you didn't post your actual address, I would have liked to send you a donation to help you move out of your step-mom's basement. Ah well, your loss.

Hey guys - is anyone actually mining with an S4 right now?  I am still mining at 2 Th/s locally but 200 Gh/s on any pool I connect to....  Any suggestions?

Are you in grade school? no wonder you cant even see bad investment right in front of your eyes..... Go ahead spend most of your energy to keep those miners of yours mining close to specs...... so you lose couple hundreds bucks LESS.

Yes.... sell it to another sucker. There are alot in here, not hard to find.

My 3 Days with 2 S4's

Both of my S4's are running stock settings and always read ~2TH/s on the miner.  The poolside hashrate is very different though.

24 Hour on Eligius: ~100GH/s

24 Hours on Eclipse: 1600-1700GH/s

24 Hours on BTC Guild: ~2TH/s (after manually setting the diff to 2048)

The problem seems to be that the pool and miner are not resolving the dynamic difficulty properly.  Eligius stick to 128 and results in sh*t for hashrate.  Both Eclipse and BTC Guild settle on 1.8k for the difficulty and yield 1.6-1.7TH/s.  If you manually select 2048 from the difficulty menu on BTC Guild I get 2TH/s poolside.

NO ONE IS STEALING YOUR HASHRATE.  The firmware obviously needs some work in order to properly resolve the variable diff.  In the meantime i'm obv mining on BTC Guild with 2048 Diff manually selected.

I'm not looking for a solution, or troubleshooting help from anyone as i've alread done the necessary troubleshooting.  (ie factory reset, cable swaps, settings, blah blah)  I'm just presenting data of my experience with 2 S4 miners and confirming there is a problem.  I can provide screenshots, but don't really think I need to waste my time with that.


TLDR;
Mine on BTC Guild and manually set the difficulty to 2048 until the new firmware is released.

Please arrange your address and phone number to be published on bitmaintech.com website. The community is very distrustful (for many good reasons) and a noob forum account asking to ship miners without prior contact is obviously raising all sorts of red flags.
