BITMAIN Antminer S3 support and OverClocking thread

[Baylard]

  No i did not , tried another software reboot , it finally came bk up ! Looks like a hardware issue , guess I gotta yell at Bitmain !

  Just a quick update for everyone , I changed out the new power control board and was able to bump up the unit without any errors ! Its been 20 min and it is still climbing ,but only at 415 m/hs avg right now !

May try different hash brds later !

Wehey! Good on you!
20mins is no time, it will climb (finger crossed) higher.
Power control board ...? What is that?

I have 1 S3 that has a low hashrate. I set to 250 with the miner configuration web page. I opened the asic-freq file and made sure it was set to 250. Still hashes under 400 GH/s. Any suggestions? I haven't loaded latest firmware. Should I?

I was suspecting my network but I have another S3 overclocked and hashing fine. I changed ports on the switch it was connected to. I was using a wireless bridge and changed it to a cabled connection to the router. Ive tried a couple lower frequencies but always under 400.

[Baylard]

   Of coarse the upgraded firmware could possibly help ! Is this an upgraded unit or the actual s3 unit from bitmain ? Are U using all four power connections ? frankly i'm not , but we are told by bitmain to do so if overclocking ! I seem to have one bad power board and one bad cable in my upgrades ! ordered three for myself and one for my friend ! Waiting for him to do his upgrade and c if everything is well before reporting the bad parts to bitmain ! Remember there website says the s3's do 453ghs +or- 5 0/0 ! if your not getting that at the stk freq then its time to tlk with them !

I've got a S3+ powered on for the first time (was used purchased on eBay) and logged into 192.168.1.99.  Under "Miner Status" shouldn't it be showing the fan speed, frequency and temps under "Antminer"?  I've only got "This section contains no values yet".  Sorry for the newbie question.

Don't worry about "no values yet".  That's because you don't have a working connection to a pool so the unit isn't hashing. This may be because the ant isn't set up to work properly on your network.

Set up your network first with a dedicated IP address for the unit and a working DNS address.  I did this by finding out the MAC address of the ANT (the "WAN" interface) and assigned a permanent address on my LAN in the permanent assignment section of my router's DHCP server, also assigned it a name  "ant1".  Then I set the new Ant to use a DHCP client to get its address.  At this point I lost contact with my browser since it was using the factory ip.  So I connected to the new IP address from my browser and continued the set up.  (With my router it was only necessary to type the name ant1 in the browser URL.) If you don't run a DHCP server on your network then you can assign manual IPs as part of setup, but you will have to get a bunch of information correct. If you do run a DHCP server and want to use it to assign a MAC address,  it is not really necessary to find out the new ants MAC address and enter it into the DHCP permanent lease table, but I find it useful, because that way IP addresses don't change over power failures.

With the network set up and talking to the ant with the new IP address I then set up the system name, time zone.  I generated a new password and wrote it down in a secure place and then changed the password for root in the ant to this new password. 

Now I set up the miner pool table with my chosen pool information.  At this point the Miner Status tab shows the values you were missing, possibly after a few second delay to establish a connection.  If not, then the most likely problem is that you put in incorrect pool information.

237.5 mhz is the best frec for a S3, mine are runing cold (39 - 40) : hashrate 450 - 460

go to this page



then go here


set up a proper internet link /path like I did.  my router uses 192.168.0.1

some routers use .1.   make all them match    to your router

 all 1's or all 0's   in that spot.

then go here
put in your pools

   Someone correct me if I'm wrong please , It is my assumption ( everyone has one  ) that the control board that comes wit the upgrades is for power reduction ! Since the new architecture uses less power they had to have something to reduce the voltage

I do not think that to be correct. I believe the control board is simply for hashing, since there are different & less chips on board, they need to be "addressed" differently. Unfortunately, the firmware on the control board chip is closed-source so no more insight into that. In fact, the control board draws power from the main hashing board to power it (and the AR933 ..? board).
Suffice to say, the power to the chips is controlled by on-board chips (on both the S1 and S3 boards).

   Well , in jumping through some hoops for bitmain before they'll give me an rma # , I stopped long enough to read the new adapter board ! It says right on it under there brand , S3_ctrlboard_Power_v1.1  ............

PSU for S3 question
I just recently bought 4 S3+ B8, and i need to know if 2 Corsair CS750M can run 4 S3+ at same time(1 PSU for 2 S3): http://www.corsair.com/en-gb/cs-series-modular-cs750m-750-watt-80-plus-gold-certified-psu

One guy told me that i can run 1 Corsair CS650M in 1 and a half S3+, so 2 CS650M can run 3 S3+, but if i had to go for the CS650M i had to buy 3 PSU to power up 4 S3+ in the other hand if 750W can supply 2 S3+ i need only 2 CS750M.

So can a 750W PSU run 2 S3+ or do i need an 850W PSU?
If i decide to OC the miners can i do it with the 1PSU(750W or 850W) for 2 S3+ B8 setup?

I have two S1's overclocked running on an 850 , I would think as long as your running stock freq you should be ok ! however if you r going to overclock them you will need a minimum of an 850 !

After about a week all 11 of my S3's will restart. Anybody else had this issue?

Have you chked your psu's ? R they overclkd? How many r on a psu ? Lastly , do you have a good connection making the jump on the psu's ?
 I Have had simialar issues when overclocking either too much draw on the psu and or the jumper just seems to lose its connection to run the psu !

Hey guys.
I've done an overclock on my Antminer s3+ and everything is changed and saved but unfortunately the clockrate and the hashspeed on the webinterface stays the same.
Anyone who had the same issue?

Did you just change the clock from 218 to 225? Sometimes that will not up the hashrate. You may need to try higher or stick with 218.

Where did you overclock? via the UI or did you SSH?
With S3+ you overclock via UI, aka Miner Configuration -> Advanced Settings then change on the dropdown. After simply press Save and Apply (bottom right corner).
