ANTMINER S3+ Discussion and Support Thread

[epichaberdasher]

Do you have your own node? A miner generates less then 5 GB a month, sorry have no exactly counter of traffic for you but its only a few MB / day

Not, not running a node for this reason, but ive got a bandwidth problem regardless its seems. Need to figure out why its happening all of a sudden. Might not be the Antminers fault.

well I'm officially done with my S3+ and shut it down, its not profit able anymore, the latest difficulty jump just changed my $25 a month to $10 a month, so its offciially dead now.

all together in my time owning it I probably made around $800 - $900 on it and I bought the unit for $200, so it paid for itself fairly well.

also its the summer time so it will be nice to keep my room cooler not having it running anymore

The halving last saturday is the problem to continue with an old S3+ miner. With only 12,5 instead of 25 BTC per block your earnings also goes down 50%.

Yeah I made a large amount with my S3 also. It was very cheap at like $50 and was quiet and the wifi feature was nice. It will sure be missed.

ok this is freaky, bitcoin price landed on 666 at the same time =/

You have to love these S3 miners. They are built really well. I am still using 4 of them in my farm until I get something like an Avalon 6 or better to replace them.

ya must have free power then.... cause right now 4 of them would only get ya $40 a month

Hi please help antminer s3 hashing board that isn't recognised. update 3 firmaware equal no working.

Hi please help antminer s3 hashing board that isn't recognised. update 3 firmaware equal no working.

Start from the first one s320140711 upgrade from there first then move up to the latest version , which mean u have to reboot a few time to each upgrade.

[gt_addict]

Have you done a reset at all while it's been like that?  Press and hold the reset button (with a paper clip poked through the hole) then let go and let it run (hashing) for ten mins.

U can reset if u like but not while u r upgrading halftway ...
Just do the upgrading from the first version  right up to the latest  that will do. No reset is require.
Check ur pool hav you enter correctly

I got three Antminer S3 from someone who quit mining. I got two of them to work and are up and mining away, but the third not so much. 
On the third one, the fan spins and the LED lights up, but the two activity lights for the ethernet port doesn't light up when plugged in. However, when turning it on, one of the ethernet activity light would blink a few times before going dark. I've tried resetting, but ethernet still doesn't work. 
Any help please? 
Thanks

Did you try a different ethernet cable?

The Ethernet cable is fine; I've used the same one for all three miners and was able to get 2/3 of the miners up and running. Any other suggestions? Does this mean I would have to get a new controller board?
Thanks

It is possible that you will need a new controller board. You could always check the cables from the hashing boards to the controller board to make sure that they are secure.

Yeah, I was thinking of that, but the rest of the controller board seems fine, all the LED's, even the wifi LED, turns on (the previous owner had installed a wifi antenna onto the S3)

Controllers aren't too expensive, though- you can order them off Aliexpress for just around 15$ with free shipping. That's the great thing about antminers, they're easy to replace

[Shermand100]

As far as I know they should be compatible. The 3 and 3+ are for all intents and purposes identical, (there was a small revision to the hashing boards a few years ago). The s3+ versions were just a string of good batches of s3 that were capable of stable hashing above the advertised 440gh/s. They called them 3+ so they could justify charging a bit extra for them. The firmware is more likely to be newer on an s3+ board due to it's more recent release date and works with both models.

(I run an s3 and s3+ on the same firmware)

[Shermand100]

Hi again, an update on my previous post. I ordered a new hashing board from aliexpress for about £20 to the UK from here https://www.aliexpress.com/item/Antminer-S3-220Gh-s-miner-Fitting-16-chip-pcs-PCB-28-NM-Calculation-circuit-board-bitcoin/32657963607.html?spm=2114.13010608.0.0.ViZuUW and the new board works fine and allowed me to remove the old one for a proper bit of testing. I previously left it in to run the second fan on the unit for the benefit of the still hashing blade.

So looking at it there are no obvious burns, warps, cracks etc. so the multi-meter came out to try and test the mosfets (the row of 8 5335555DQP chips). I pulled up the datasheet http://www.ti.com/lit/ds/symlink/tps53355.pdf but these are a little more complex than I'm used to. Granted a bulk of the pins are the 12v in, and the 0.8v out for the BM1382 chips. But some of the other signal and reference voltage pins threw me just due to terminology as I stated this is only a hobby and not a profession.

I settled for trying to test pins 3 and 4 as my best interpretation of gate and drain. Can anyone weigh in on that? Was difficult to test with certainty due to tiny pin size but seems ok.

However if the mosfets are shorted drain to gate as they most probably would, to my understanding as they are set up in parallel the open gate having drain voltage across it would damage all other mosfets as well, killing the whole board. This is a possibility and fit the symptom of the whole board failing at once, with the 12v fan plug unaffected at the top of the board. The replacement chips look costly as they are more complex than simple mosfets. They have many other features and each chip looks to cost around £7 in a small batch order. Making repair un-economical as all 8 would need changing, assuming the mosfets blowing hasn't also damaged the driving circuitry too.

Again is anyone interested in electronics with some knowledge to share? I'm keen to have an attempt at repair, for my own experience, and as it's a currently dead board it's only good as repair practice or a coffee mat. May as well repair it.
