Best option would be to use any cheap psu with green and black shortcuted.

Thank you for the reply

a) What do you mean by "green and black shortcuted"
b) How would I actually power-on the PSU?

That is exactly what I mean
You need to shortcut green wire with black wire on 24 pin mother board connector otherwise it will not start
And additional advise make your wire connections tight otherwise they can melt

They melt because you load too much power onto one wire. Try to spread the load out to as many wires as you can.
Never take the PSU to it's max box wattage, some of its watts are for the 5v and motherboard.
Try an get single power rail PSU if you can as that helps avoid some loading issues as well.

If you have the green and black wire shorted, and still no luck, another issue for non-mining boards can be a surge protected USB ports.
I try to avoid USB hubs that mention surge/power protection.

I know dude, but they also melt when molex is crapy with bad pin contact or you are in a hurry and just spike two wires and tape them
That was I what I tried to explain

I know ur a pro, I mean the msg for the newbies, sorry for confusion.

Ok, so it has to be a PSU. hmm X_X

I have a spare Xilence 550W. Unfortunately it has 7 black cables and 1 green one.
The label looks like this.


I am counting 9 fields per row (2 rows)

The connector to the mainboard hat 10 connectors per row (2 rows)

How do I identify the correct black cable?

Every black is correct. How many boards do you have. If one just use two blacks from PCI-e and two yellows
It is not single rail as gator ( he is a pro also) advise so be careful.

[nookiegirl]

I have two miner and already prepared to molex adapter - one for each miner.
Is it safe to just plug them in?

The question about the black was: Which black should I shortcut to the green one as there are 7 black cables.

It does not matter whichever you like. They all go into one place inside psu
Make sure you use separate wiresto plug molex into.  As gator advise be sure to spread the load

This power supply says it has 2x +12v rails...

17A x 12V = 204W
18A x 12V = 216W

...treat it like it's a 420W Power supply and don't put more than 204W on any single line!
Also always read the small print on the wires for the AWG max amp/watt load too just in case it's lower than 204W.

Here is a chart with the performance of HEX16A2, keep in mind that the consumption may not be very accurate:

    1000/0900mV ~24W - 15.86GH/s - 1.51W/GH (less than 1% HW)
    1300/1020mV ~56W - 20.30GH/s - 2.76W/GH (less than 2% HW)
    1400/1060mV ~74W - 21.28GH/s - 3.47W/GH (less than 2% HW)
    1500/1120mV ~92W - 22.85GH/s - 4.03W/GH (less than 2% HW)
    1600/1160mV ~108W - 24.15GH/s - 4.47W/GH (less than 3% HW) - hot

As you can see the efficiency drops dramatically when overclocked. The power connector of the boards is a standard molex which is rated to deliver upto 132W at 12V, HEX16A had similar power consumption and that was not an issue. However I recommend you to stay bellow 1500Mhz, the hashrate gain just ain't worth it.

To connect this board to windows 7 all i need to do is download hex miner 1.0.0.3 and plug it to my desktop psu or is there more downloads needed?

I heard about stratum proxy, is that needed as well?

What does it do?

Sorry for noob questions.

This video shows you how to run a Hex miner from Windows...

You're better off using a TP-Link router for running cgminer on though, it's only 2W of power!

[Zich]

I just removed a fan and holly crap the fans on my second shipment are 4.7W 4500 RPM!!!

http://www.alliedelec.com/search/productdetail.aspx?SKU=70226025#tab=specs

They were only 2W Sunons on my last one!

At 5v they'll probably still do 1875 RPM!

Seriously these fans are dangerous at 12v 4500RPM without any guard. Watch out!

UPDATE: Just set all the 4.7W fans to 5v. Seem to be keeping things cool enough. I'll keep an eye on it for 24hrs.

Ok, now i feel so stupid looking for replacement Fan.
The SUNON Maglev PF92251V1-000U-S99 is PWM fan, so what i need is to build PWM fan controller.

Thank you, I found the section that describes how to patch cgminer.
For everybody else (and my own reference) here is the link again:

http://sven-goessling.de/14/12/2013/der-40ghs-hex16b-bitfury-asic-bitcoin-miner-auf-dem-raspberry-pi-14-12-13/


Another question arises:

I want to use them on my raspberryPI, so is there any possible way to connect them to a normal plug somehow?
Anybody done yet? My cgminer does not have a desktop-psu.

Thank you

Just info: currently available patch afe7710858e4ce28bb60f6ae6e167a18d687634f.patch is for cgminer3.8.5, will not working with cgminer3.10.0.

Thanks Gator.

Yes I am aware of that, but I want to test it with windows first, when I get a few more boards to connect together I'll grab the TP Link as well.

[blitzwilli1]

at 5V to the fan
the board will be hot and it no longer works
is there anyone else happened?

[marto74]

So switch to 12 V
Most probably you room was warm.
If you managed to blow some of the power supply components send it back for repair/replacement

I had a brief power outage and now in the API log I get this

 [Firmware Version] => 20131221
cgminer: 3_8_4_afe7710
Socket connect failed: Connection refused

CGminer is not runing any ideas?

No internet/active pools or board not detected use shah and check what is going on
