ANTMINER S3+ Discussion and Support Thread

[TracerX]

if anybody order the antminer s3 by bitmaintech.com?
is that reliable site to order?

That is the official manufacturer site, it's legit.

this is 8 out of 9 S3 ants hashing at or above 441G/hs @stock clock ..
i ran out of thermal paste for the 9th is why its not up yet ..
i have 30 grams gc-extreme thermal paste due to arrive monday ..
i have not tried to oc them yet but i might try next week ..
it's all about giving these the right amount of loving is all ..

Did you do just the front, back or both?

So all your saying you did was re-paste and got better hash ? lol

[squashpile]

B4 has been solid for me so far. I have one @ 225 the other stock freq. I have not seen any drop in hash rate yet. It's only been 24 hrs though. I do have one that does not report fan speed. Maybe the batches are improving? What do you guys think?

well i did add some aluminum heatsinks to the small black chip above the grey chips as well .

SSH into your miner

What exactly does this mean?  How does one SSH into the miner?  Any help on this?

I see from the image you use P2Pool, but what type of management are you using for those what I assume are some sort of widgets ?

[squashpile]

That is CGRemote. I also use MultiMiner. They both work well.

Cool! I have some coming. Did you use pads or paste on those little black chips?

Look into over-clocking. You are basically allowing yourself access to the code.

Since I've added '/etc/init.d cgminer restart' to my crontab I've seen my 24-hour hashrate increase from 410 to 480 on my GOOD units. From 398-420 on my "Bad" units.

Some people are more code-friendly than others. chrontab is a bit too much for me right now.
what would be the string of code to put in after sshing to miner and in what directory?
If you don't mind, show us all commands, please.

You should contact Bitmain.  Perhaps they can include that modification in a firmware update.

I have already contacted Bitmain about adding a restart timeframe to the firmware. (Much like many of the SCRYPT mining controllers)
BEAR IN MIND, I AM AWAITING BMT ENGINEER'S ADVICE REGARDING RESTARTING THE CGMINER PROCESS SO OFTEN.
There may be a reason they didn't include it as an option, but I'm more apt to believe that they simply just didn't think to do so.
That OpenWRT controller is still VERY MUCH a router.

Here's the rundown. It's very basic stuff.

SSH into your miner

crontab -e

This will load up the crontab editor, the usage is the same as Vi
Press I to enter 'Input' mode.
Add the following text below the monitoring script.

0,30 * * * * /etc/init.d/cgminer restart

After doing so, press ESC to get back into command mode.

Type:

:wq

This will write your changes and quit.

Type:

crontab -l

This will let you see if your new entry has been added to the crontab.

If it's there, you're good to go.
If not, Google how to use Vi or read one of the many posts in this thread that explain it.

How often does cgminer restart with those settings?

it restarts at 0 minutes and 30 minutes every hour, day, week, and month. Basically every 30 minutes but on the hour and on the half hour if your clock is correct.

An easier way to do this if you don't want to mess with crontab is to use the web interface. Go to "System"->"Scheduled Tasks" and just add the 0,30 * * * * /etc/init.d/cgminer restart command there. Save and Apply.

What would be the code for every 6 hours, 12 hours or 24 hours?

Does Bitmain have an official ebay account? I can't get ahold of bitcoin atm to order :X

Is anybody running three S3's from a Corsair AX1200i without problems (not overclocked) ?

Just wondering if this will be OK, I have the offer of a cheap one from a friend.

Every half hr, lol, thats waaaay too often.

Once a day or every 12 hrs should suffice.

is 12,00 * * * * /etc/init.d/cgminer restart
the command for restarting every 12 hours, then?

could someone comment if this is OK to put this in <System> tasks instead of ssh-ing?

there is no proof that re-pasting affected any of this, and I assume that this is just after a few hours. Some units have a habit of starting bright (at >470), then spontaneously dipping back to 440GH or even lower.  It is also possible that OP had great units to begin with.

no they do not.  how do you want to pay for one with paypal or  a cc?


there are good resellers that will   sell you one with a cc


this guy sold quite a few with a cc

the first four in that list are longer than 24hrs ..
i might be overclock testing the S3's soon so we will see ..
i modded these S3's before i even connected them to a psu ..
so i do not know what they would have hashed at before replacing the paste ..
they are all still holding strong hash rates so far ..
