Need help setting up my antminer s3 farm

[d3v]

Hi everyone. I'm running four antminer S3's as well as one bitamain S1 and one spoondliestech SP1x dawson which totals approx 4.5th/s hashing power and want to know if uk1.ghash.io:3333 is the correct address for ghash or if I should be using -o stratum+tcp://uk1.ghash.io:3333 instead?

ghash says...

Please use -o stratum+tcp://uk1.ghash.io:3333 in your command line.

...but I cannot see any "command line" box within my S3/S1 setup pages?

Is the uk1.ghash.io:3333 address stratum enabled? Do S3/S1 machines use stratum?

Also why isn't my balance changing after 3 hours of mining at ghash? I heard something about your balance increasing after a shift, but no idea how long a "shift" takes?!?

Also is ghash the best pool these days for quickest BTC generation? Is slushy's pool or eclipse consortium better options?

Thirdly, is it best to have a single ghash worker ID, or one for each of my 6 mining machines? (probably a silly question!) and also should I set my worker ID difficulty to 1024 since I'm well over 1th/s hashing power??

and finally is there any tweaks, settings, tips, ect I can use to maximize my hash rate and speed up BTC generation?

thanks in advance!

bump: please anyone?

use stratum+tcp://uk1.ghash.io:3333

you will probably find if you use just uk1.ghash.io:3333 it will automatically add the stratum+tcp:// anyway.

Give each miner their own User ID, and then give them their own difficulty accordingly.

You wont see any BTC add up until a Block is found, and then your last 10 shifts will determine how much of that block you earnt.

Great thanks for the reply. I also asked the question about the -o prefix to ghash support team and they replied with...

Hello,

Leave the -o argument in, it is needed. Off the top of my head, I believe that it tells the program to look for the alternate algorithm argument (so it knows what algorithm to hash under).

It is advised to use separate workers, it is easier to troubleshoot hash rate failures this way.

Difficulty is self adjusting on our pools. If you have cloud GHS, this is a non issue as all of the cloud workers are internally managed. If you are connecting hardware to the pool however, connect initially without setting difficulty. If you should see an unacceptable invalid share submission rate (above 1 percent), adjust your difficulty to something high and arbitrary, like 1024. The system should automatically adjust your difficulty based on your invalid share submission rate and hash rate, and assign you the correct difficulty.

I hope this helps! Please write me back if you need additional information.

So, according to them I leave the -o present?!?

Also have I set everything up correctly in the image, for instance did I set the difficulty correctly for each miner, and why do two of the miners have red icons in the "5m" column? What does it mean, and why does the antminer S1 have so many stale shares?

Your "support" doesn't know what they're talking about. The -o is only if you are using the low level cgminer commands directly and has nothing to do with the web interface. You just need the URL and port on the web interface.

The red just means its a lower reading than it has had previously, you can see it up the top where it says 5m and has the red down arrow with -4%.

Its perfectly normal to do that.


That S1 reading is way out, id say check the firmware version and see if it needs updating, then look at doing a manual cgminer update, theres links to it here in the forums, I think in the hardware section.

Hello Axiste and very well spotted. It's actually an antminer S2, I wrongly thought it was an S1! That must be why the stats look so wrong!

On ghash I'm currently at 12% of one bitcoin, after 71 hours of mining there, which equates to 0.016 per hour (i think)? Last night seemed a particularly profitable night with higher than usual payouts, and more frequent payouts. Not sure if I was experiencing some sort of reward for mining there for 3+ days, or if I was experiencing the random ups and downs of mining profitability that I've read about.

 Does anyone know if switching to http://www.clevermining.com/ would be more profitable than ghash?
