ANTMINER S2 Discussion and Support Thread

Mid 50's. I have recently moved it to a different room/circuit and that's when the problem started. But the temps haven't increased.

Interesting, I've never been over 52^o (usually around 50) and my psu is doing fine, perhaps it's the temp that's causing it, I'm not sure what others are running at. With the cutoff at 80^o one would expect it to handle high temps, but maybe the psu is struggling.

Also, if you've changed it to a different circuit, I'd expect it to trip at your breaker box, not at the psu if that was the problem.

I live in the desert so the house is very warm during the day even with the A/C running. I have a Kill-a-Watt and if i can find it, I'll check it out. Oddly, since I first posted, it has been running fine without interruption.

I just got my RMA for 1 board that's hashing all XXX's - Now to ship it back

Is it hashing at correct speed but showing XXX or not hashing at all?

[tzortz]

Is it similar with s1 xxx?

I wouldn't know if this individual chip is hashing or not but my overall hash rate goes down approximate about 100GHs so I assume that it completely stops. This is the only board that shows XXX in whichever slot. All other boards work flawless.

I am not certain what Bitmain/Bitcointalk policies are regarding coupon usage so if this violates any terms consider it null and void.  I have a $400 coupon for an S2 that I will not be using.  If anyone is interested PM me and maybe we can work something out to both our advantages.  I live in NYC (Staten Island) and work in North Jersey if that helps.

I have 10 of them and don't plan on using them at all.

Why would you? so you can get another broken piece of crap in the mail?

Maybe this time Monkeys wont jump up and down on your box and throw it over their shoulders on tho the plane.

If it does actually work, you are lucky and should pray to the gods for receiving an expensive overpriced item that "should" work but for 85% of the time for users doesnt.

Those coupons are his way of saying F-U go ahead buy more of my crap, since i lowered it a little.....but people are stupid and they will buy, and they will be dissapointed, and they will complain.

But in the end they will have a nice looking box with some shiny pieces of metal on it to display on their mantle and can turn it on to show their friends how fast the fans spin. (unless you get one of the ones the monkey jumped on, then you will just have a pile of broken parts to show off).

A year? What hardware BTC miner remains viable for a year?

HI Guys,

I have about 50x$400 coupons, I am happy to share it for a little profit, if anyone interested pm me. Thanks

[MrTeal]

Well, mine definitely broke somehow. All of a sudden I just started getting massive rejected shares, and my hashrate dropped to 500-600GH/s

Anyone else experienced anything similar?

pool issue? eligius is all over the place the last 2 days.  otherwise does the webUI indicate it is certain boards faulting or an overall drop in speed?

I don't think so, it does the same thing at Slush and Bitminter.

If I SSH in, I see a lot of this...

The S2 might last quite some time, assuming in a few months it could lower to 800GH and achieve ~0.8W/GH to remain competitive. low electricity costs and a rise in BTC value would help

I guess I have to scroll through 115 pages to find out how to change password on S2.

So, I fixed the problem. After dicking around with trying to pull cards out to see if one was bad, I eventually just pulled the SD card and returned it to stock, then set it up again.

I really with they hadn't been so cheap and had put the eMMC on the board so there wouldn't be SD issues.

no problem, just call bitmain im sure he will be more than happy to help you..oh wait scratch that...if he knew how to help you it wouldnt have come all fuc!%$ed up in the first place...good job bitmain...keep up the good work, im sure you will  sell a lot more of these pieces of crap to people and expect them to figure out out re-engineer your piece of shit.

I say dont spend another dime on his useless crap until he compensates everyone for their losses, and not by giving them a measly $400 S2 store credit so you can buy another door stopper.

I say BOYCOTT!!!!!!!!!! the "man"  that might get his attention, and keep his monkey's in line, and quality test his product before selling it to you after he mined with it for a month before wrapping it up and stomping on the box before sending it to you.

why do you think each batch drops $500 a week or so, beacause when he is done mining with them and the difficulty rises he sells them a little cheaper tricking you into thinking you are getting a good deal when you will NEVER ROI on those used pieces of shit, if they come to you in one piece and actually turn on.

hey bitmain, why not send each of your S2 customers 6 S1's as compensation for this?  those seem to work well.

but i wouldnt hold my breath as he is a greedy bastard, and is only looking out to screw you at this point....go ahead and RMA the unit so you can be out 2 weeks worth of mining while his engineers diagnose what is wrong with your unit and maybe give you what he thinks may be a "fair" compensation for it.....ha! what a joke.

you had a good reputation and business...i dont think so anymore...JUST SAY NO!  he will get the message when no money comes into his wallet.

what a jerk.
