ANTMINER S3+ Discussion and Support Thread

[Moria843]

I know the feeling. I was also debating buying S3s but now holding to see what happens. I'm still mining with 8 S1s and they're down to pulling in about 1 BTC a month. At my electricity cost of $0.13/kWh this cost me about $340/month. So I'm still making a small profit at the current BTC price. May upgrade using the kits, but not worth it yet. Waiting to see what happens.

You really need to look at the pencil mod of your S1's I did my 9 miners and now they mine at only 140GH but use @ 200 watts less apiece. So now my electric cost (.125kw) is about .51 day each. You will make more profit doing so. Then this also freed up PSU to run some S3's

Not sure what you mean by pencil mod? I guess you mean lowering the frequency. I'll PuTTY in and try that. Thanks for the advice.

It's this - https://bitcointa.lk/threads/guide-undervolt-antminer-s1-1-19w-gh-at-the-wall.286480/

I've done it on my S1, works great.  As aurel57 mentioned it'll increase your profit margin

just wanted to report that all nine of my S3 ants have been running flawlessly at 500+g/hs all month long.
i have not had to reboot a single one of them for the last three weeks.
my S3 ant farm colony is running as stable and strong as the my S1's.
of course i did make some mods before i started running them.
the above screenshot is what i see every day all the time without any reboots.
thanks bitmain for the great miners!

would also be interested how you mod them to get that high hashrate stable...

I'm interested too on the mods. I had mods some GPU with a great gain (decoupling capacitors...Step down converter...).

This is from 4 S3 Antminers.  So what's wrong here?

Well it does seem like an extremely high proportion of stale and duplicate work. I know this isn't related to hardware errors but there is one miner which seems to be producing a relatively high percentage of HW errors also.  I didn't screenshot that as it's only about 1.6%.

You're misreading the graph. Hashrate and rejects have different scales, one on the left side, the other one on the right side. Under 1% of rejects is not high.

Ah,  thanks for that.  I guess I'm reading the numbers in the pop up info box wrong too? I've never used ghash.io before. Just out of interest, what difficulty should be set for S3 use on ghash.io? My ghash.io account defaulted to 1024 initially but I thought this to be too high, so set it to 256 like it was with vardiff on Eligius.

256 is fine and 1024 is ok too I think. If you go higher than that the hashrate chart will be choppy and if you go lower you might get bottlenecked by network and/or controller.

You need to match the stale/dup numbers against the number of diff 1 shares submitted. You are submitting ~300,000 shares per round and occasionally getting ~2000 shares rejected in some rounds... perfectly fine as far as I can see.

nice graphics and charts

Hi all, i have an s3 that will not hash and it has a red & green LED light that will not turn off. i have done a facotry reset, reflashed the firmware, checked ssh/putty settings...i am clueless as to what's up with it ?  it was hashing fine until a few hours ago.

i am able to access the web interface, but the UI shows no frequency nor does it hash.  anyone else experience this  ?  thanks

If you reflashed with the new firmware its necessary to select a frequency, save, restart before it will recognize the setting. Beyond that it may be an issue with the PSU being stuck in standby which would need the psu powered down and the jumper removed for about 20 seconds to allow the capacitor to bleed down and release the protection relay before reinstalling the jumper and powering back up.

Anyone have any S3s coupons they're willing to part with?

Hello Hello
yes great there is a new Antminer L1 coming

What could it be...

For sure a litecoin miner. Speed is in MH/s - opposed to GH/s on bitcoin miners

Thx Mazedk, well seen, i was not too awake yet lol

problem solved--i think.  apparently my Antec 1300w PSU went bad--weird.  i put another PSU on, reflashed all, put the 6 pin PCI-e in the 2nd set of plugs that the s3, and presto i am mining again.  this s3 has been such a problem child.  thanks for the heads up with PSU troubleshooting.  i never would have thought my 1300 platinum 80 plus antec would go kaput.
