Anyone know if the S3/S3+ suffers from the same "no internet" error where it sets it self on fire thats happening with the S5/S7 ?

Never have had any issue like that with my S3/S3+

I have 2 antminer s3+. One that is fine and one that yesterday stopped finding the hashing boards. I can connect to the controller card and have reset and changed the firmware(downgrading to the first firmware for the S3+). I have also swapped the controller card from the working one and the power supplies to see if that fixes the problem but it does not.

When the S3+ boots up both fans turn and controller card and network are up(I can access the web server of the controller card). On the miner status page though it does not show any information under the “ant miner” panel. Pool is alive too by the way. LED lights are blinking both RED and GREEN quickly at the same time. Load seems very low compared to the other miner too. Under the system log it looks like the controller never finds “USB Bitmain asic”.

 I also see +3.3V on the controller and +12V on the hashing boards at the large capacitors on the top of each hashing board. So it seem like power is getting to everything the way it should.

Any help would greatly appreciated. I have a ton of S1’s and they have been happy hashing for a year now so I am surprised this S3+ seemingly not being able to recover.

I have also reset my router and my power supply is a CORSAIR CX series CX750M 750W which is running just the one S3+.

You have checked that 3v3 from controller? Check if it gets to hash-boards too. Also check 1v8 in the hash-board. And oscillator if you have equipment. Also swap cables from working unit. Connector pin 3 is 3v3 and pin 4 is 1v8.

Thanks for you reply. I will check the voltages on the pins you suggested. I did try swapping the data cables from one unit to the other and that does not change the bad unit(cables from bad unit on good unit work fine).

Here are the voltages coming from the controller to the hashing boards :

Only Tx line is not what it should. It's that 1.8 before it starts to hash. When it's hashing that voltage drops somewhere between 1.5-1.6 volts. If you have an oscilloscope you can check if there are pulses,or is it a flatline. It's fourth pin from left in upper row. I would suspect pic's fw but if same thing happens with other controller too that can't be the cause. Check if oscillator is running on hashboard.

Hi guys,
This is my first time using a dedicated miner, few years ago I used my graphics card.
Do these stats look ok regarding the s3? and what is the best method for making the s3 last? keeping the temps cool? turning it off once in awhile? cleaned out the fans and internals when purchased. Got this at a bargain price in the UK £80 looking to expand on this after a few months.

Current Setup, running at 428.4 Gh/s.

Iv noticed my miner drops to 350gh/s then back upto 400+ is this common?

not sure if this is in the correct section.

Just for a common knowledge: Faulty chip  is U21.Marking on top reads: EB=3L. Short circuits 1v8 and 3v3 lines. Controller seems to boot but after that red and green just keep flashing. Pretty easy to repair, just six legs in that component.

having an issue with my S3+

Just recently purchased through craiglist.

Worked for 3 days without issue now I get XXXXXXXX. I've tried new PCIE connectors, New PSU, updating and loading original firmware to no avail. Any assistance would be great. thanks!

Also the HWs are high as heck!

i have some thermal paste on order going to try that first with reapplication. One board shows ------- on another miner. Hoping the boards aren't dead just need some touch up. Any other suggestions would be appreciated. thanks!

Take it apart and measure the voltages going into each chips. They should be 0.75V

2 are also blinking red and green together. I tried new PSU and tried moving a miner that works control board to try that but nothing.

is there a guide to how to check the volts going to the chips?

Has any one thought of combining a couple of s3's together sort of like the C1 but not changing over the heat sink. I mean Sort of like how the s5 is done. Would it be worth it? I mean have one controller controlling all 3 s3 instead of three separate units?

I think the problem will be getting the controllers.  I doubt bitmain has C1 controllers in stock anymore (I could be wrong, they may surprise me). 

But if you do I think if I remember right will allow 4 blades so I think you could hook up two S3's.  But by the time you add this I think it's just not worth it. S3 are getting dated I would try to use separate and squeeze out more profit instead of buying the new controller, unless your doing it for sake of modding and not based on ROI.

Was thinking it might be more efficient running 4 or more together than separate.

It would be more efficient to run 4 blades vs 2.  The problem is the price of the controller if they even have them in stock on C1 controllers.  When you pay say 150 per S3 (was 100 before price of btc went up).  The 40ish dollars I'm guessing on controller just is a decent amount of the machines overall cost, even divided between the two.

Granted it makes it easier as 1 IP for the  4 blades.... but I think it's not worth it unless you happen to have controller laying around.

Yep, I have done some testing with these. Original S3-controller was propably meant to control more than two boards. It's schematics show connections for 4 hashboards. But problem is that firmware has support only for 2 hashboards. In hw-level I can read code from pic-mcu and reprogram it, but changing that code would need assembler coding. It's propably easier to write new code to do that. But coding isn't one of my best skills. Open-wrt module's software is also capable to update that pic's code so it might be possible to tweak it's drivers. But again,it's beyond my knowledge.
There might also be a reason why they dropped that pic/ar9331 controller out: it has only 2 physical uart's. Some of pins can be programmed for uarts but I'm not sure if that pic is fast enough for it. Some wiser men have told me that it works if the baudrate is low enough. But I really don't know, I'm just a hobbyist.
Ofcourse it can be done with usb/uart adapters like cp2102. You only need to do level shifting too and provide 1v8 and 3v3 to hashboards. It works, I have tested it, but every hashboard needs its own cp2102 adapter. I might try to build an adapter with cp2108 in it. So it could drive 4 boards with one usb connection. And it should have some pwm-controller for fans too.
