Topic: ANTMINER S3+ Discussion and Support Thread - page 324. (Read 710164 times)

The bounty is offered by me and some one else also promised to add additional to my bounty.
The bounty is still active and anyone can participate to win.
The link to that thread is https://bitcointalksearch.org/topic/diy-reward-100-antminer-s1s3-blade-on-raspberry-pi-671128
The aim is to run multiple(>2) blades with a single control board.
You can do it on S1 or S3. Hope soon participant will join as more S1s are available at cheap price now.
On a side note: how we track our old threads open by ourselves? In other forums there is a page were we can see threads started by ourselves.
But I think I miss it in bitcointalk.

You gotta have em, for people like me who are new to owning Bitmain, outside of the USB devices, we don't have that option. Still wont know what I'll have to worry about til I get my damn units ;-/

what about old S1 controllers?

There was a bounty thread somewhere around here for making old S1 working with rPi. My S1 is still profitable, and I would like to maybe upgrade them soon with S3 blades.

Bitmain mentioned that they will sell upgrade kits. 

Also, for those with faulty control boards. What about keeping the units powered as they are now but wiring the unit with a bad control board in to another S3's good control board or am I missing something else here ?

Or just wire them in to an rPi with MinePeon or something.

I wonder why, its not as if someone can run off with another controller and build an Ant from it........it should just be heres another one and toss that piece of shit in the bin....they must know that about 1 in 10 of these things are faulty.

I found that down clocking to 212.5 stabilised the hashrate at about 410-420 GH with a hard restart every couple of days.

I'm in the same boat.  I ordered 3 units of batch 2 and the first one out of the box had a faulty controller.  I got the other 2 running, and they're hashing away at normal rate with no modifications.

I contacted their tech support about the faulty unit, did some troubleshooting that they advised (swapping it with a board from one of the working units, using different PSU, etc), and isolated it to the controller board on that unit.  This took only a few days of troubleshooting. 

Now I'm at over a week, and I finally get an email from their support with a shipping label.  I asked for clarification, and they expect me to ship the faulty board to them before they will ship me a replacement.  A process they say will take another week.  So I'll be over 2 weeks with a dead unit, and the next difficulty looming - basically at least .166 BTC lost because of their faulty hardware and slow response.

I asked about compensation, and they said they do not offer compensation.  Given that these units are priced so as to be barely profitable, I am now in a situation where I will most certainly lose money on the deal, while Bitmain has potentially made millions off of their customers.  I find it staggering to think they can't offer simple customer service solutions that are commonplace in other industries - especially with mission critical or time sensitive applications (which bitcoin miners undoubtedly are).  I mean, at least cross ship the replacement board or offer that as an option.  But they drag their feet, and insist on a time consuming return process basically ensuring I'm out any profit that unit could have delivered had I got it mining the moment I received it.

I have another 2 units on B5 and I've requested they cancel my order if they can't make this right. That might seem like an overreaction, but I have a simple approach to those I do business with - and if they don't treat me like I would treat a customer in the same situation then it's no deal.

Hopefully we can all make some noise here and get Bitmain to change their tune.

Makes ya wonder why they constantly ship f'n lemons, also makes me wonder what I'll end up with out of the 4 units I ordered.

Nothing yet , waiting to hear back

Since mine has the same probs as yours, what solution did Bitmain offer to you to rectify the faulty control board.

S3 not hashing correctly?

I've got 4 units and only 1 hashes at 440-441 at stock freq, the others get 414-420ish.

In working with bitmain over email I tried re applying thermal paste and swapping psu's around and still nada.  Then they asked me to swap control board from the one good miner to one that is underperforming and lo and behold the underperforming one is now hashing at 440-441 with the other hashing at the lower speed.

I've swapped it on then others and it's the same result.  Since the static IP is saved on the control board it moves from swap to swap with the good control board, so it constantly thinks it's the good unit and hashes at adv. spec

What are the error rates?

Seems to be working just fine!

Running for the hills with this ? lol

BITMAINTECH.COM OFFLINE. Anyone know what they are doing?
edit.. disregard. back up and no changes

Depends when you ordered. Between 4 orders of mine and some friends we have them at all various stages for batch 5. Our first time stamp is in china, while our second order is in ohio already. Our third order is moving along and the fourth order has yet to start the process.

Wishful thinking they ship before the 6th.

Am I missing something, it's only the 4th right now, still a strong possibility as far as I can tell..
