Any wire may is ?

If this 20pin dont have my psu , what do i?
This 20 pin that will dont connect psu

ToQcHista you really need to find a way to express yourself in a better way. Try google translate from your original language to english.
Its hard to understand you and its hard to answer your question.

The wire (paper clip) need to be done to power the PSU. When you plug you ATX psu into a computer, you use power button to power on the psu. This is the same think with this wire. It will power on your PSU.

Hope it help. 

The wire IS necessary. If you do not do it the power supply will turn off as it is expecting to be controlled by a computer. Putting the clip in tricks it into staying on to power the miner without a motherboard.

Yes. The antminer will not turn on without it.

This wire is necessary ?

Ok then correct.

This proces that i dont will do , what  will happen?
Talking about wire.

Will working psu ? If i don't conect this wire working  if dont working antminer and psu.

Dont is hard understand.

It is hard to understand what you are trying to say.

See if you can find someone else who understands English a little better to explain what you want to know.

No disrespect intended.  Only trying to help!

I that this wire dont will make , what happen ?

Without wire that will turn on antminer this antiminer will working ?

I dont understand

thanks answer.

I do that don't will do this wire,  what will happen?

It allows the power supply to turn on without a motherboard.

why is this wire Necessary ?

that dont will make? what happened ?

No, I did not.  You?

Did you try 150MHz?

I HAVE DRAWN THE CONCLUSION IT IS NOT WORTH UNDER-CLOCKING THE S3 or S3+ [At least at present price of bitcoin].  In fact, the more over-clocked they are the better.  I don't know that it would ever be worth under clocking it?  I can see under-clocking to make more power available to add more rigs with a higher hash rate to your present set up.  That's about the only advantage.  As well as having a faster interface with the new firmware upgrade.


S3 @ 270 watts [under-clocked at 175 MHz @ 0.68 volts (0680) and 340 to 360 GH/s (I chose 350 GH/s for the math)]

$0.106 (10.6 cents) per kWH power costs for 270 watts:

Cost Per Hour:   $0.028620
Cost Per Day:   $0.686880
Cost Per Week:   $4.808
Cost Per Month:   $19.23
Cost Per Year:   $250.02

Power costs at $0.106 (10.6 cents) per kWH for 380 watts:

Cost Per Hour:   $0.040280
Cost Per Day:   $0.966720
Cost Per Week:   $6.767
Cost Per Month:   $27.07
Cost Per Year:   $351.89

With BTC @ $273.471 & Difficulty at 46,684,376,316 and S3 tuned to 175 MHz @ 0.68 volts for 350 GH/s @ 270 watts:

Mined Per Hour:    0.0001571  BTC   $0.04296  USD - $0.028620 pwr. costs = $0.01434 per hour
Mined Per Day:     0.00377  BTC       $1.031  USD - $0.686880 pwr. costs = $0.34412 per day
Mined Per Week:   0.02639  BTC       $7.217  USD - $4.808 pwr. costs = $2.409 per week
Mined Per Month:  0.1131  BTC         $30.93  USD - $19.23 pwr. costs = $11.70 per month

With BTC @ $273.471 & Difficulty at 46,684,376,316 and S3 tuned to 237.5MHz @ 0.725 volts for 480 GH/s @ 380 watts:

Mined Per Hour:    0.0002155  BTC   $0.05893   USD - $0.040280 pwr. costs = $0.01865 per hour
Mined Per Day:     0.005171  BTC     $1.414       USD - $0.966720 pwr. costs = $0.44728 per day
Mined Per Week:   0.03619  BTC      $9.897       USD - $6.767 pwr. costs = $3.13 per week
Mined Per Month:  0.1551  BTC       $42.42       USD - $27.07 pwr. costs = $15.35 per month

I copied only the portion where he mentioned it.  Here it is:

Anyways, I was running the numbers using some kill-a-watts and when I downclock the S3's to 175Mhz and lower the voltage to 0.68, they seem stable at about 340-360Gh/s but still run about 270watts each. When I run them slightly overclocked at 237.5Mhz, I get around 460-500Gh/s and uses 380watts.

So after calculating it (I pay $0.12 per Kwh here in CT) I make an extra %40-50 income per day.
The larger SP20's I can run with no electricity costs, so that should be much better.

I don't have power meter on my own but what did your mate found out on your setup?

You're welcome...

My Kill A Watt meter burned out on me a couple of days ago.  I got a buddy of mine to do the same things with his S3's and he has a Kill A Watt meter.  It turns out my reading on my Kill A Watt meter was defective.  The rigs are still more efficient at the new settings.  They just are not as efficient as I had first anticipated because of a defective meter.  That' 2 Kill A Watt meters gone bad on me now.    

Anyhow... I'm glad I could be of help.  I wasn't sure if all of the firmware updates had to be done in order to get the rigs to work properly.  I just heard so many stories of people jumping straight from their present firmware to the most recent with sob stories.  So, I thought I would just go up the ladder [in order] and everything worked fine with all 18 S3's [Some of them older S3's and not S3+'s].  I'm absolutely loving the faster interface with these now.

Many thanks for sharing your experience dmwardjr, I have updated my 2 S3+ and my 2 S3 today to the newest firmware and copied your settings without any problems!
Miners running nice quiet now in my garage and I will have a look at the power consumption tomorrow after 24h running.

Have a nice evening (in Germany its 21.14 now)
