ANTMINER S3+ Discussion and Support Thread

[SMB-2525]

I cycled a circuit breaker last night. That caused both of my S3s to not hash when they came back up. The fan in the S3 is running, but it does not come up.

The power on sequence goes like this:
Red light flashes for about 20 seconds
Green light comes on for a second - at the same time the network link lights come on
The red and the green lights go out at the same time. The network link lights stay on. The fan stays on.
They do not respond to ping or login attempt.

Each is on a 750 Watt Corsair PS and the whole lot is on a surge protector.

Did I kill them?

Interesting. Leaving them off for 5 minutes did not fix it. Leaving them off for 20 minutes did.
After a longer capacitor discharge period, they came up and started hashing on their configured IP addresses.
Those are some capacitors.

Thanks for your suggestions - they got me to try again rather than drink myself into oblivion over the $7ish/day in lost BTC revenue.

We will just have to agree to disagree there. If a breaker is rated at 20 amps load at 110v it will certainly hold 1920. I also speak from experience here. Long term loads of 1800-1900 months on end. No issues. But yes the breaker will get warm.

Good luck with that.  I hope your breakers work correctly.  Some of them don't.  I replaced my entire panel because the manufacturer, Federal Electric, produced breakers that didn't shut down reliably in the case of overloads and caused a number of house fires.

Another factor to consider if your power is subject to brown outs...  Your miner power supply will attempt to maintain a constant voltage to the miner and hence constant power output even if the line voltage drops.  This means the current draw will increase.  So if you have reliable operation during periods when your supply voltage is high you may have difficulties if your voltage drops.  Should this happen, you can hope that your problems are tripping breakers and not breakers that you wish had tripped but didn't.

A charged capacitor will have a voltage memory.  Hold a capacitor at voltage for a while, take away the source, measure the voltage across the cap, then completely short it, say put a wrench across the terminals for a minute,  remove the short, wait 30 seconds, measure the cap and some voltage will have returned.  

Years ago working for a company that built DC motors there was a machine with a huge bank of capacitors that would get charged then the charge shorted thru coils around magnet blanks inducing a permanent field.  I was assisting the troubleshooting.  The guy doing the troubleshooting had a shorting cable the end of which was attached to a stick.  To make sure the caps were discharged he'd short with the shorting stick.  We went to lunch.  After lunch he reached in and got badly knocked on his ass.  Actually he was more than just knocked on his ass.  I think he was knocked unconscious, thrown some distance and suffered a significant burn.  I didn't witness the accident.  Ambulance came and took him to the hospital.  He felt someone hit the charge button while we were gone.  I couldn't disagree with him.  Years later I realized it may have been that voltage memory.

happened to me. check the dns.

Did they reset to factory setting ip address?  If  you are running two or if you have a different ip address base you would have trouble getting to them.

Need inputs & advice please,

How much watts when it comes to power supply that can power 1 Antminer S3 and how much Amp in 12v rail does it need?

I have 5 antminer S3 and planning to buys separate power supply for each.

Thanks & Regards,

It needs about 30 amps on 12V but I don't think it's a good idea to have a separate power supply for each. You will end up with 5 power supplies (450-500W each) and a mess of cables, while you could get one 800-850W and one 1200-1300W PSU and put 2 and 3 miners on them respectively.

So 1200 watts is good for 3 antminers S3.

Actually my problem is here in Saudi they don't have much supplier when it comes to PC and all they hay is 400w to 500w PSU, but they have a 1300 watts platinum but price is overkill.

Anyway I have not made any decisions yet, any advice on brand if ever I go separate power supply?

Thanks,

Ok, in that case get some good 500W ones, 80+ silver/gold if you can. Corsair is fairly good, not sure what else is there in that range.

Edit: technically 450W is sufficient if not overclocked.

Thanks for the advice, I'll try 450W since I'm not into OC'ing.

...........

Did you set them to DHCP or manual IP? Try one at a time, also try to connect to the default IP. Failing that try to reflash the micro SD card, you may have killed that.

This is the Antminer S3,  and not Antminer S2. There is no micro SD card.

ANTMINER S3+ -B9

Sold Out

yeah, saw it 1-2hour ago or so

B9 maybe the leftover from B8
so its not that much left

now, lets waiting for this weeks deadline... S4!!!!!
hope its stuck at BTC3
so, we who bought S3+ wont be crying like baby haha



EDIT: OMFG, B10     
seriously??? this S4 will be at least BTC3 LOL

[Master One]

Did one of you get one of those S3 delivered to France (or elsewhere in the Euro zone) ? How much taxes did you pay ? Winter is coming and I could use 350W of constant power inside my home, which would make the ROI a bit better.

You pay import VAT which is the same as your local VAT. So in case of France it's 20%.

I found Corsair CX500M 80+ Bronze...is this good enough to power Antminer S3 (24/7)?

Yes, although some people say the M version is junk.

[vortexz]

I just got my 2 S3+, they are actually worse than my batch 6 S3
I have overclocked my first S3 to 243,75 MHZ and 250 MHZ,
I can't get the S3+ working above the standard 225 MHZ


they promised th S3+ is better as it should normally be, but I see this is worse !

So it ok to use CX500M 80+ "BRONZE" even if it is bronze and not gold?

What settings did you try?

[kabopar]

Just saw that there is a S3-B10 (no price) at Bitmain

Use EMS for shipping. You will have lot more chances to get it without VAT and custom taxes (I got 2 S3 last week without VAT/taxes).

If you are not lucky, +20% for VAT, 2.5% for customs. Something near 80€

[stef942]

yes use EMS because they dont collect taxes for custom as UPS, i bought several S1, never paid taxes.
