How did you power them? Looks to me that they have problem with psu(s).
Hi! There was problem with router. I rebooted it, then rebooted the miners, and everything all right!

Still not a very good picture as you have to take at an angle unless you take the board out from the frame. I have corrected the perspective but focus not that good.
The resistors to parallel across are marked with red lines.

Those look like tiny SMD resistors, did you have any issues soldering those resistors?

You might have the older S3 miners where you can adjust the voltage. The ones I got the voltages can't be adjusted, you need to solder a resistor to lower the voltage.
The above measurements were with adjusted resistors, more information here.
I decided to try my hand at Undervolting the S3, I would like to play with the S5 but am hoping the second hand prices will come down a bit first.. Although there are posts around that say you can change the core voltage using the Advanced setting field, like some others have found on my S3 & S3+ it seems to make no difference to the voltage.
I wanted to be able to easily adjust the voltage so I soldered in 2 x 4 channel 5K digital pots across the VFB resistors. These are setup with an Arduino, which also measures the voltage set..
In practice I have just rediscovered what other have found, but it's good to see the numbers for yourself.
The Standard S3 with 218.75MHz clock had a core voltage of 0.8V hashed at about 440GH & took 321W at the wall giving J/GH of 0.73
After trying a lot of frequencies and voltages I decided it was possible to continue at 218.75MHz with the voltage reduced to 0.73V. This gives a small number of hardware errors .001% but improves the J/GH to 0.65. I soldered 4K7 resistors into the S3 an am letting it run, while continuing to play with the S3+ with the digital pots.
At my electricity cost this moves me from Break Even to about £1 Week profit. I am happy with this for the moment as it's buying BTC and my Wife is happy as it's drying the washing.
As would be expected as you drop the frequency and Core voltage the efficiency increases and the J/GH drops.
The best I have seen was at 125Mhz, 0.64V Core Voltage, giving a hash of about 254GH which is J/GH of 0.48. This was with 270 Ohms across the VFB resistor and at this point I run out of adjustment on the core voltage as we are very close to the TPS533355 0.6V reference voltage. However I am actually surprised that the chip was still hashing at this voltage.
I could probably squeeze a slightly better result by doing away with half the DC-DC converters and moving to 4 chips per, as the currents are now much reduced. I may try this later?

Here is a summary of where I have got to. I had to increase the core voltage slightly at 125MHz as with more testing I got an x....
Code:
MHz V Core GH W J/GH R Ohm
206.25 0.728 412.5 271 0.66 4700
150 0.69 300 165.6 0.55 1800
125 0.64 250 122.4 0.49 330
The R Ohm is the value of the resistor soldered in parallel with the existing VFB resistor.
The watts for the 206.25Mhz were measured at the wall, the others were calculated from the Voltage & current drawn from the PSU on the bench so might be slightly out, but will be very close.
Rich
Thanks for the info. Was wondering if there is a picture online somewhere showing more clearly which components needs to be soldered in parallel.
The one posted by valtic was taken at an angle and its hard to see.

Yes it works very well. My results here.

Here is what I have found works, by trial & error, at the lower clock frequencies.
The J/GH at 100MHz should be better but I cannot get the Core voltage low enough as am now very close to the TPS53355 DC-DC Converter 0.6V reference voltage.
Code:
MHz V Core GH W J/GH
175 0.685 350 197 0.56
150 0.66 300 154 0.51
125 0.64 254 120 0.47
100 0.63 200 96 0.48

i manage to undervolt my ant s3+. here is the result
stable at 305gh
freq 150
config voltage 065
HW .003 30 ment. idle
new firmware
191watts on wall i use digital corsair hx850i
stable at 305gh
freq 150
config voltage 065
HW .003 30 ment. idle
new firmware
191watts on wall i use digital corsair hx850i
Thank you for this..
however, if you change the config voltage, I doubt any change in watts at the wall. that setting has been disabled as per BITMAIN_Janet upthread just a bit.
your getting .62 watt / gh
really looking for someone to take this thing apart and see how we can reduce the actuall voltage to the chips more then just changing the freq does.
here is the better result
update new firmware
310gh
freq. 150
adv. config voltage 065

Did anybody actually try undervolting their S3 with this resistor hack? Just wondering how its been working out with stability.
0.6Watts/GHS seems like a good efficencty.
Hello everyone!
Have a problem with S3! 8 miners knocked out of mining. All eight are connected to the Internet (yellow LED lights, blinking green); at 6 6 have two diodes constant light (red and green) at the same time, one S3 has a blinking connection diodes ONLY, and one is blinking green LED (+ connection).
Miners were overloaded (in the menu/OS adjust) then reinstalled on defult and then again regained their settings - nothing helped. Does not give any sign, only blinking ethernet connection.
Here are screens - work schedule (I dont understand what they show, maybe someone can!) and the status of the miners.
Can anyone tell what is the problem ?!

First thing would be to check if the PCI-e connectors all burned. Since they all stopped at the same time it *could* be possible you burned them all if you do not have proper surge protection.
Secondly did you power cycle them, along with the router? I have an issue where when one S1 bug out, sometimes all the S1s, from different PSU, connectors etc everything all lose local connection. To fix i have to restart the router.
Did you mean PCI-e connectors inside miner?
The PCI-e sockets. In the S3 there are 2 per board and they're the thing you plug in your PCI-e female(tube) connector into.
If you remove the shroud/cover it would be pretty obvious to notice if they have blackened. But you should be able to see just by looking at them with the PCI-e cables unconnected.

PSUs are okay. I want to change the firmware. Can't find the data of old firmware.

No. 
No? As in "No i lose money over this and i do it only out of good will." Kind of no? How come? This should easily run on a server hosted in a affordable datacenter. The monthly cost would be be minimal compared to 14THs commission.
Currently it's about half my fee ... which is also very low
In the future it could be better, but over the past few months ... no.
Look in the blockchain - Aug I got ... 3.65BTC in pool fees (yes -ck gets some of the fee also - that's my part of it - but I pay for everything)
This month the fee total will be lower.
Not sure what some might consider a good datacenter and a good powered server to run a pool, but monthly server fees are not small unless you are running crap or someone else is paying for it.
A miner is now pretty much a set and forget item.
I know, I've had many different miners over the years, and I write and test the software that runs on lots of them
-ck and I wrote a lot of the software in most of the miners running on the planet ...
A pool is more than a full time job.
Some may think my time is worth nothing ... I don't ... but I don't expect a lot (and don't get a lot) for the very large amount of time I spend on Bitcoin.
Not sure what specs you need but my friend pays 40$ per month to host his industrial grade server in the US. He has /27, 10tb band, 1gb ethernet. He pays the same for his Supermicro E3-1230v2 server. I wonder where your 400$ premium goes. Do you need 10 of those?
No.

No.
it looks like we are just a couple of diff increases from the s3s being useless with anyone over .08 cents /KWH power cost.
Hmm that's good I pay 9c but that's is Aus$ so with the $ exchange rate that's 6.3c
(at the current exchange rate)(I also only mine 9hrs a day, the rest of the day it's a LOT more than 9c - it's 29c and 50c)
Wow that's some crazy varying rate. No wonder you keep it small. I guess running a pool is your best bet at decent income. First time i see such crazy rates.
Yeah, sure, decent. Your personal time consumption aside, it must be an efficient hardware cost/electricity cost to revenue ratio.
13.5Th/s is not a whole lot but its not negligible either.
