ANTMINER S3+ Discussion and Support Thread

[windpath]

I have two S3's, received last Friday. One of them hashes at 440GHs at stock speed (218.5), so I'm fine with it; however, the other hashes at 400 GHs at stock. I've been trying different things like putting it on a different psu's like ATX, Dell/HP server, but nothing helped. I'm taking notes on different clock speeds on this one:

Frequency     GHS(avg)      Temps       HW            Watt (Kill-A-Watt)     ASIC Status
----------     ----------     -------     --------     ------------------     ----------------------
250              487.26          41, 41        2             428                         Chain#2, 1 "x" on the far right
237.5           423.55          39, 37       38             367                         All OK
225              422.69          39,36         7             364                         Chain#2, 1 "x" at 2nd position & 1 "-" at 8th position from left
218.75          403.58          40, 38        0             355                         All Ok

After editing the asic-freq file, a reboot command was issued. All readings were take at 30 minute mark. PSU is a Dell Server Power Supply 750W. All 4 PCI-E cables are plugged in, even at stock frequency.

Yes, it took me over 2 hours to finish writing this post.  

I'm setting the frequency at 250, seems to be the sweet spot for this S3.

At what frequency would you run this at? Why?

At 218.75 freq you are getting 1.136845 GH per Watt
At 250.00 freq you are getting 1.138457 GH per Watt

Looks like it is slightly more efficient at the higher clock speed, but 30 minutes is not a sufficient test. I'd keep an eye on hash rate, temps and errors for the next few days.

Thanks for sharing

Edit:
Here is an easy calculator to figure out your HW Error %:

(was built for S1, but works the same for S3...

At what frequency would you run this at? Why?

so you spend 940 usd worth of mining equipment for $16 aday?

Why do you care and why are you even on here. Go away. It will probably get ROI in 3-4 months and thats not including resale value.

Just trying to understand why bother?

Without bitcoin miners, bitcoin dies.  Transactions are not processed. Everything you're holding becomes worthless.   That's why we bother.

It's also a fun hobby for us that makes money. We enjoy the technical aspect of it as well as supporting the cause. That's also why most of us are DOS'ing UPS's tracking site wondering when customs will get done installing their custom spy chips. LOL (really, I'll be watching where these go)

Up S3 arse, of course.

I would come up with a killer line and rip you for the blasphemy written,but I often ask myself the same question.


Here is a possible future for 2 s-3's.


Now if I put 950 usd in a bank I get 1% at best  so my 950 becomes 959.50 in 1 year.  

In my case below my 950 becomes 1008 in 7 months.  I don't count internet I have internet.  I don't count psu's I have them.  I do count cost and power.

1)  So I do far better then a bank..  

2)  There are tax breaks in the usa for mining that do not occur for buying and holding coins.

3)  upside  coins have been known to have big bull run-ups.  under 90 in Sept 2013 to more then 1100 in Nov 2013.\

 holding coins will  make profit as capital gains, but mining them will create  income that is subject to self employment tax.  In the usa …  So  depending upon your circumstances you may want to pay into Social Security   mining allows this if you profit and report.

I was a bit surprised to read Anddos response right after my post. Haters will be haters. Ignoramus will be ignoramus. Seriously, why did he even bother coming in this thread, is something I will never understand. It's like someone barging in, dropping his pants and taking a dump, in the middle of someone's party. Some people have no common sense. At all.

I cant understand why people are purchasing s3's, the return at the current difficulty is 8usd aday, about 50 week and you spend 468.5 usd??

How are you going to make your money back, not forgetting running costs...

this friend still dont get it
mining isnt all about ROI, money, profit, etc.
its not like we're rich,

for some of us, its like a hobby, dont you ever get tired of something?
what'll you do if so? u'll try somethin new, right? what if u're tired again???
u'll get bored by finding for the new one...

and, why BITCOIN?
we, this community, wants to see how far this babe will fly...
at least we're a part of it

once again... its not all about profit, money, ROI, etc....

For many of us this is a hobby that we all understand will not make us rich. I will be happy to break even. Just like my other hobby that I throw money at, I have a race car that I know will cost me more than I make in winnings. Why do I do it? Because I enjoy it.

If you are depending on your Bitcoin mining to survive, you need to find a better way to earn a living.

I like to play the "Let's see if I can take this BTC and make more BTC game" too, but at the end of the day I started with a USD200 video card and have had a blast playing with everything in-between.  If I turn a profit, neat.  If I don't, I still got to play with some cool toys.  Win-win.

agree with this
for living = get a job
for hobby = spend ur money

You enjoy throwing money down the drain?

Okay, pal.  Move along.

[hawkfish007]

Got my Batch 2 miners this morning, they are hashing at 444 GH on average for the last hour at factory clock (218.75) 

[dropt]

You enjoy throwing money down the drain?

In my younger days I was into rebuilding/modifying cars, and let me tell you: this is nowhere near the same level of "throwing money down the drain".  When it comes to hobbies, most cost a lot and return nothing but enjoyment.

[bobsav2121]

You looking for an expensive hobby . try FLYING , that makes all this look like spare pocket change.

thats why people like Anddos tend to mark us as "crazy people"

I'm with you on this. I quit making $$ spent entries in my race log after I broke into the six figure bracket, that was 10 years ago. So far I'm into BTC for a $1000, and have $100 back.

Just think if we spent as much on mining gear as we did on our cars...............

I'm having "not buying enough S3 remorse.  Bitmain, can you open up Batch 4 to returning S3 customers only plz?
