I know pay .035 to mine .021 i just laugh to my btc wallet. These people who lease rigs pay in btc so thier generally i doubt hiting roi form a btc view but i see the same users doing it so they must have some stratogey for makin it work. Hey if they dont lease it then it mining one of my pools. Win win for me.

0.035BTC per day seems to be a good payment rate for 1 Th/s (good for you that is). My 1.6 Th/s mining currently only producing 0.03 to 0.036BTC per day. Guess you have to figure he's not maintaining and has no sunk cost, but I still don't see how he's making money. Believe it would be better for him to just buy the BTC.

Which numbers are u looking for the ones from an bitcoin roi calc say electricity is free and btc price stays flat.
Or are you referring to my pool luck comments

I must of missed my goal in the comment. Bitcoin mining is speclative. And thier is a chance to make a profit or atleast some think thier is. I have a person that pays me .035 btc to rent a 1 th miner a day. Not sure why all calcs say you can only get .021 a day guess he is ethier loosing it or he has some secret pool that pays nicely.

5.6 kg

Mailed one this morning. Just under 13lbs.

Some very good points well made.

Sadly I don't see the situation changing, it's such a skewed equation at the moment with all the profit going to manufacturers and all the risk going to customers.  I don't think there is a single piece of hardware out there now that will generate a profit for the average miner.  We all know due to the frequent price drops that manufacturers could lower the price and allow both parties to make some money, but until people stop buying overpriced hardware they aren't likely to change the way they work (and I can't say I blame them)

Does anyone have the actual weight of an S3 in the box (not just what bitmain prints on the label)?

Have some number to back up this claim?

I know the feeling. I was also debating buying S3s but now holding to see what happens. I'm still mining with 8 S1s and they're down to pulling in about 1 BTC a month. At my electricity cost of $0.13/kWh this cost me about $340/month. So I'm still making a small profit at the current BTC price. May upgrade using the kits, but not worth it yet. Waiting to see what happens.

So would I.  I have five S3's and not one even comes close to this.  I have one with chain temps of 23 & 25 and it still only hashes @ 430Ghs clocked at 237.5.  If I clock it to 250 it gets worse.
Maybe some shenanigans here?  lol

Hello Bitmain,

Is there any news on this yet? Only a few days to go, and I'd sleep a lot easier at night knowing that the glaring security vulnerabilities in my Antminer software had been finally fixed  

Thanks.

Edit: This goes for my S2's also 

Go to www.frozencpu.com and get the right pieces you need.

I need some PCI 6 pin power Connector plugs for S3. Ebay prices are very exorbitant.
I wandered many component stores and no one stocks them.
Earlier I found one thread which describing how to make them from Motherboard connectors.
Can anyone point me to that thread?

would also be interested how you mod them to get that high hashrate stable...

Just did a hard reboot, and swapped the plugs to the other connectors, seems to have done the trick, its nice and cool in my farm today as well.

My S2 does that trick when it gets hot. Usually a full 30 second power off fixes "-"s for me. A soft boot doesn't seem to be enough of a motivation. 

Hi, anyone shed any light on this?



Been running @250 for the past 3 weeks solid, then this morning that happened.

Ive clocked it down, but I'm assuming I've fried one side.

Any ideas for a repair anyone?

Well, I have been playing with the idea for two weeks now, and I have come to the conclusion that I really have to write off the idea to start mining with either a bunch of S3+ or two SP31, as it's just not worth it.

Even when calculating energy costs with only 0.0921 $/kWh (which is an unrealistic value for me here, that I could only achieve with a little trickery) and a difficulty increase of just 20% per month they are not going to reach a positive ROI or turn negative just when reaching.

And yes, it's not only about reaching a positive ROI, but to make a profit as well. If you buy a S3+ for BTC0.58 it has to mine BTC0.58+ independently of a rising BTC value, because otherwise it would have made more sense to just buy BTC (considering to become a hodler).

We have to face it, with a total network speed of more than 200 PH/s at the current difficulty, increasing with such rates the 28nm ASIC technology has to be considered as obsolete, as it's just not possible to squeeze it at less then 0.5455 W/GH (at the wall; that value is for the SP31, with the S3+ it's 0.7837 W/GH or overclocked 0.8 W/GH). Energy is not going to get cheaper neither, so we really need new hardware.

The hardware manufacturers currently are not able to keep up with the increasing difficulty, and without a miracle it pretty much means the end of private mining. This may seem pessimistic and there may be new opportunities with tech <20nm but it really depends on the manufacturers' strategies, because if it stays the norm to keep customers waiting while mining the hell out of new units themselves till difficulty kills the opportunity for the customer to reach a positive ROI again, nothing is going to change.

I really was that close to hit the order button on a couple of S3+, but now I'm just going to watch the BTC value, buy a few BTC for hodling when it feels right, and wait for new hardware to be announced (which most likely is not going to happen this year).

Good luck to you all, especially to those who are as late to the game as I am and didn't do the math.

It's indeed nice to know that they hold up well in higher temps but just the same, YMMV considering the assortment of performance variance among the S3s that we have come to know.

I'd like to think that re-torquing the heat sink screws before firing 'em up made a difference.  I'd also like to think that setting up my units in V-Air (Vertical Airflow) configuration made a difference.  Who knows.

Yeah, warm and fuzzy, that's how you treat them

Reminds me of my garage in the heyday of GPU mining. Good to know that the S3 doesn't mind these temperatures.
