Are there any S3's left for sale anywhere?

S3+ is available from Bitmain on 20th September

Are there any S3's left for sale anywhere?

Might be doing yourself a favor not finding any. Batch 5 at .64 when btc was about 600 each = about $385 USD, S3+ = .58 at about 500 each or $290 USD now. As of now you could have bought the .2 bitcoins and been in que to get the S3+. Depending on ship date you may end up being a lot better off in the S3+ batch anyways, especially if the hardware is built/assembled better.

I was thinking of getting some S3+ but with the uncertainty, the potential new chip around corner (if its not a scam) The cgiminer thing, I decided to hold off on anymore hardware, buy some btc direct.

Anyone with the  B7 shipping status so far?

I do wish the BITMAIN would publish the device driver details so that a current version of cgminer could be attained. I know at least 2 releases in 4 had notes about queue improvements and one at least specifically stated it generated work much faster. Also one of the last 3's had an improvement about how work was loaded into devices. I know for sure 3.12 is very old and I am positive that many work generation improvements have been added since then.

Exactly. I don't understand why they don't work more closely with the cgminer devs - using such an old miner for this equipment is false economy. There have been many improvements & optimixations since this cgminer release, not to mention a very important fix for work redirection by a third party.

Can we just SSH in to it and compile CGMiner to a newer version ?

One would assume that we have access to their modified code and driver for cgminer which the cgminer license stipulates, however they have ignored our requests for making that code available. I am considering what direction to take now about that license violation.

Indeed, I saw your post requesting access to the code - ignoring it seems a very strange course of action by Bitmain, especially since agreeing & cooperating would not only benefit everyone - but would also stay within the legally binding license terms.......

I hope they realize their error & do the right thing - as well as live up to their claim of supporting the Bitcoin community.

@ckolivas: Is there anything we, the community, can do to help? Maybe if we all started mailing them they will take notice?

I for one am not buying any more equipment from Bitmain until this is taken care of. I often wondered what if a person could skim off a very small percent of hashing on equipment and get away with it not being noticed. Makes a person wonder.

Hi BITMAIN.

As you're an official representative of bitmain, may I ask you to please provide the source code for your modifications to cgminer in the form of the driver for the S3. cgminer is provided under the GPL version 3 license which means you are obliged by law to provide the source code to any modifications you do if you distribute binaries and you are distributing modified cgminer binaries with every S3.

Provision of the source code would allow us to aid the development of your driver and help bring your version to sync up with the latest cgminer to derive the benefits of newer versions along with its many fixes.

Bumping this

BITMAIN - A couple questions please:

1)  Why do you continue to ignore the request by the cgminer developers to release your code as you are morally & legally required to do so under the GPLv3 License Agreement?

2)  The cgminer software that you are deploying ILLEGALLY with your software has SEVERE security flaws, including the stratum redirect issue - why are you NOT implementing the latest version to eliminate these issues?

These and other questions have been asked many times by many people across this forum, but you continue to ignore them, refusing to even comment, and by doing so you are not only breaking the law, but you are also demonstrating massive contempt towards the cgminer developers & the Open Source Community as well as creating suspicion as to your reasons/motives within the Bitcoin Community.

Until you decide to capitulate & do the honorable & legally binding - and above all, the RIGHT thing - I and others on this forum will continue to pursue a response/reply to the above questions.

I urge everyone on this forum to do the same, not only out of respect & gratitude to the cgminer developers who have given so much to the Bitcoin community FOR FREE under the GPLv3 Licensing Terms, but also to ensure the security of your own extremely vulnerable mining equipment purchased from Bitmain.

Thank you.

@BITMAIN, everybody here is waiting for a statement on this issue, so this is really something serious that has to be addressed.

In the meantime I'd like to know about the pool setup if running a couple of Antminers. From the S3 manual I can see it supports three mining pools and three pool balance options (Failover / Balance / Load Balance).

Can anyone please advise a strategy when running a couple of Antminers?

I guess most will just leave the default balance option (Failover)?
Let's say you have 6 Antminers, do you let them mine each on a separate pool?

I have been wondering this also. Is is bad to to use the same pool and same worker ID for 3 seperate miners? Should each miner if using the same pool, use a different worker ID?

No, it's absolutely no problem - using separate ID's just means you can monitor them separately

it is probably better to use a different worker id for each miner (for troubleshooting), but they can mine to the same wallet. In Eligius, you can distinguish between workers by a simple _<name> like <wallet address>_myS3 (wallet underscore name).

I am having an issue. It seems when I am overclocked I am having an issue where my average GHS is reading a low number. What is the problem? Is it an issue with the pool I am using(Slushs) or is an issue with my OC?

If I reboot my miner the issue will be fixed for a while. I just dont understand what the problem is.

if your hashing average is low on the pool, i would suggest to downclock your miner

I bet you just reset your router, your hash is fine, just the reported number isn't, reboot and your numbers will look correct.

Hi,

Can someone point me to the right direction on how to customize my S3 (and some Cointerras too) to mine properly with P2Pool???

They are mining currently, but with around 15~20% less GH/s.

Thanks.

Is there a way we could update cgminer on the S3's ourselves? Just a thought

  We don't have the driver for it.

Which is what you want Bitmain to release. I see now thanks

No, due to Bitmain refusing to abide by the GPLv3 License & release the code as mentioned in the bold post above. I suggest you email Bitmain & request that they do so immediately as many others are doing - including the cgminer developers

HELP!  My Antminer S3's suddenly stopped.  I just received them three days ago.  I got them configured and running easily.  (I replaced an S1, so I was already familiar with the set-up).  They worked fine for the last couple of days.  Today they started beeping.  When I go to the GHash.IO page, I can see the pool is still up and mining away.  But for some reason, I'm no longer mining.  When I log into each miner, and check the miner status tab, there are no stats.  I already tried to power down and re-start them.  What do you recommend I look at next to trouble shoot this?  Thanks.

If one pool goes down, always try a backup pool first to test its not the miner-pool configuration before moving on to more drastic steps.
