ANTMINER S3+ Discussion and Support Thread

[nottm28]

The shipping of B5 started, 7 days earlier than promised date. We added more B5 units for sale.

What about B4 ? That hasn't even started shipping yet has it?

Mine shipped on 7/29 and  is scheduled to be delivered on 8/1

When did you order?

Thanks. Maybe they have actually shipped and I just haven't had the notice - that's happened before a few times...

Yea I have had that happen before. I ordered almost the same time and I didnt get any notice either...

since there are so many miners here and I want to buy ANTMINER S3 I'll post my question here. Is there a chart of multipool mining profitability in fiat over a long period of time (6-12months)? If not maybe you can tell me from your experience..

I want to know whether the current $1.6/100GH/day is somewhat stable and can be expected to stay that way the coming 6 months.
(I'm a newbie regarding mining, so with this miner I can use it for multipools right? )

I'd take some serious time learning more about bitcoin before you invest a cent. The difficulty changes after every 2016 blocks.  Here is a list of the historical increases.

https://bitcoinwisdom.com/bitcoin/difficulty

In the last 6 months it has gone from ~3 million to ~19 million. SO NO WAY you will be making anything close to $1.6/100GH/day in 6 months.

thanks! I know about bitcoin difficulty and got burned already
I'm asking about the other coins since multipools mine the most profitable, which ever coin it happens to be. But there is no "profitability" chart of multipools over such a period of time.

I have been mining at multipool.us for several months. I haven't kept detailed records but can tell you that it now spends >95% of the time mining bitcoin directly, not any of the other coins. The way the pool works ensures that any of the more profitable coins will be mined until they are approximately the same profitability as bitcoin, so it effectively destroys its own market. I imagine the other multipools will have roughly the same effect.

The only way to beat the multipools is to mine newer coins before they get added to the pools, which is a bit of a gamble and isn't a set-and-forget option which I think is what you are looking for.

It is a circular system.  You buy equipment to mine, it increases the network hash rates,  so they increase the difficulty, forcing you to buy more equipment to stay profitable, all the new equipment causes them to step up the difficulty again, and make you buy more equipment again.  Basically you are spending all your profits on more equipment to stay as profitable as when you started mining months earlier.  All in all, the only ones making money are the equipment manufacturers and the power companies.  The network hash rates is growing so fast now that you can't make enough profits to invest in solar/wind power to offset the power costs.  Once you get into the loop, it is hard to just shut down $20-30K of mining equipment that has only allowed you to buy more mining equipment.  Nothing in your pocket to speak of.  Kinda sucks unless you have hundreds of thousands invested in equipment already.

Guys: I been testing a few SP10s in a room in my office, normally the temp is 90F degrees because I have 4 of them in a small space. One day it was 100 degrees in there! The end result what the miners worked great, and I am actually moving them to the datacenter today.

Question: What are you thoughts about running this S3 at 80F? 90F? 100F environments? Would they just shut off? I may test today at 80F. The way I make the temps go up or down is to turn on more miners. I have a room for testing, but there is no ventilation in there. Its a big room, but it heats up fast. Would love to hear who is running at what room temperature. I am sure 80F and below is no problem...

What prevents you from mining with a couple Th at home, for which you would pay only ~2K.
Nobody said that you are supposed to make a living out of it.
To me, it is interesting and feels like a contribution to bitcoin success in some way

up to 85F is no problem for both S2 and S3.

Several hours ago I posted a screenshot asking why I do only have ~250GH/s while the miner is powered with a 1600W PSU and all ASICs looked fine. I restarted the miner and let it run a few hours. Now it looks like this:


It seems that some ASICs can not be detected. What can I do in this case?
Thank you

Have you taken the unit apart and checked your thermal paste?

down clock to 212.5 freq via ssh

My first two miners worked like crap at 218, 225, 237 ,250  they work well at 212.5

I've had S2s run up to 85F and had no issues - haven't stress tested any S3s with high temps as of yet but going off previous results, you should be fine in the 80-90 range. Triple digits, I wouldn't suggest - probably start to see the hash rate drop a bit + wear the units out faster.

I will test today in my back room. Thanks for the input. The fans on the SP10 are super high RPM, and these seem to be not as high. I will also look at putting in different fans in these guys. Any thoughts on 110v fans, or would that be a waste?

try diferent PSU (yes i know its 1600W, but really sometimes just PSU is bad)

The thing is that the temps are so low on chain 1 in this pic and your previous one. Something is not right with that first blade. As others have said check out the thermal paste but I think it may be something else. I would contact Bitmain for a RMA.

[jfederkins]

Has anyone received coupons from Bitmain for Batch 5?

I did not, and initial coupons were only for Batch 1-3.
They could still issue coupons later on, but there was no announcement re this.

[Aexcu]

No problem with S2 at 160F, but if you go somewhat beyond it will shutdown.

I run 4 S3s at 107F continuously for days.  Rock solid.  Graphs to prove it.

Great info! I will try mine today in that room!

Have you taken the unit apart and checked your thermal paste?

When BMT recommends checking the thermal paste, are they talking about the front-side or back-side heatsink?
There are two per blade. Is it pointless to remove backside because there are no SMCs?

Still unshipped. No record of Order ID on the UPS site either....
