That's all good psu. Maybe you want to check the heatsink. See if the heatsink touch the chips or not. And give some load on +5V rail. Some psu need load there. Heatsink seems OK but I'll look at that tomorrow. I've got a 20 watt metal resistor I can put across the +5. |

@Zich.
I tried your suggestions and the same thing happened. Miner worked for about 10 minutes, went sick, went zombie went dead. For now I'm using the config that resets cgminer when the hashing falls below 50ghs so its fine.
I never have any luck with TechnoBit's stuff. I probably should have avoided this miner too.

$185 shipped to 75071? I know its low ball and all but....

Well, I'm just guessing so bare with me.
Plug in one at a time, find it via your routers "connected devices list" or "DHCP list" and go to that address in a web browser. Config as needed, move onto the next miner.
There are IP scanning programs you can run in Windows that will find everything connected to your network. You can probably use one of those to find it too.

I found a version of cgminer called "dice version" (I think its on technobits website). It seems to be capable of detecting when the miner gets below a gh's threshold and it resets itself.
So far in the last hour or so its reset itself and the miner 18 times.
Heh.. It just reset again.
Try these setting: "hexminerm-options" : "4:1024",
"hexminerm-voltage" : "820",
"hexminerm-chip-mask" : "15",
"hexminerm-hw-err-res" : "50",
"hexminerm-nonce-timeout-secs" : "20",
"hexminerm-pic-roll" : "90",
"hexminerm-reset-below-threshold" : "10",
"hexminerm-reset-wait" : "600",
Thanks for the pointers! I'll give this a shot tomorrow. So the miner has had to be reset 202 times today. Fun stuff...  |

Its going to take more time but perhaps it would be best to do one miner at a time. If they come out of the factory (or where ever you bought them from) with a static IP address you could have a bunch of them with the same address and you'll never get that worked out.
Also, could be that some of them are on a different IP range than your network.
Example... Your network is 192.168.0.x and some of the miners are 192.168.1.x.

There are two config file that I'm using. This first one ends up with the "last received nonce 2 seconds ago" lines over and over again and never mines. This is the config file that comes with this modified version of cgminer.

"kernel-path" : "/usr/local/bin"
This next config file is created by the same version of cgminer but will only mine for about 10 minutes. It will eventually crap out and say the miner is dead. By created I mean I delete the cgminer.conf file, start cgminer, enter my pool and user info and have cgminer write the config file.

I'll post the config file's text when I get to the miner later today. I was thinking about using a TPLink device but I dont have one handy. I'd hate to throw money at this thing if its just going to be a PITA.

I'm having zero luck getting this thing to work for longer than 10 minutes. I've followed the thorough setup guide here and the one on technobits site. No matter what changes I make to cgminer's config file the miner goes dead within 10 minutes or so. I've tried other pc's, different usb ports, different cables, powered hubs, non powered hubs, nothing....
Anyone here have one working in cgminer mind posting their config files text?
Thanks!

I managed to get it working.
I used an image from highoncoins.com and put it on another 16 gig sd card. I'm able to hash into it and change things now so thats good.
I also tried minera and could see that the miner was working but couldnt get into the web page even with that software. I tried another pi and was able to get into the minera webpage so I guess something is odd with the pi that came with the device. No worries though, I'm up and running and can ssh into it to see whats its doing so thats all I need.
I also changed those front fans to +7VDC rather than +12VDC. They were way too loud at +12... I added 2 120mm fans on the back of the blades to help pull air through. So far they are running at right around 42C still.

OK, so I've verified that x.x.x.24 is the miner and is the only RasPi on my network. I can ping it from my Win7, Win8 and Mac computers but cant gain http access from any of them. The Mac will SSH into it, I dont have putty installed on any of the Win machines. I can tell for sure that the miner is mining as its drawing close to 430 watts from the wall.
Thanks for the help.

NoScript is a browser plugin that prevents webpages from running scripts by default, for security reasons. If you don't know what it is you probably don't have it.
I could walk you through manually editing the pool info through SSH, but it's not really very user friendly...
It's odd that you can't get the web interface to work, are you sure that you're going to the right IP? Where did you get that IP from? What hands out DHCP addresses on your network?
On a Windows machine, do this:
Start--->Run--->cmd
ping -a 192.168.0.24
See what it comes back with as a hostname. If it's not "miner", it's likely not the g-black, but something else.
You can also do arp -a. Look for 192.168.0.24 in the list, if the MAC doesn't start with B8-27-EB it's not a raspberry pi, and therefore definitely not the g-black.
A computer tech friend of mine gave me a program that pings the entire network and lists everything thats connected to it. That program is finding the pi at that address and as far as I know its the only pi I have on my network. Is it as simple as typing the web address into a browser address bar to get into the thing or am I missing some text? For example, should "192.168.0.24" get me in or is the login similar to FTP over the internet where you have to type something like " pi@192.168.0.24?" I have a DSL router handing out the ip address. Thanks for the help. If I cant figure it out I'll PM you my phone number. |

I use Minera software to control my G-blacks. It works very well. You can get to it via web browser. Don't use IE, it doesn't like Internet Explorer. I set the freq to 815 and it runs very well.
Thanks, I'll check that out. FWIW, I was trying to get into it with Chrome on Windows and Mac's. Neither could get in but the Mac could SSH into it. Weird. That is weird. So you can use that IP to SSH into it but when you put it in a browser nothing happens? Are you running NoScript? I dont know what NoScript is. Yeah, I can SSH in from my Mac's terminal.... "ssh pi@192.168.0.24" and I'll get a password prompt. From there I dont know where to go to change the pool info. If I enter "192.168.0.24" into a browser address bar I get an error 504. |

got into it via ssh... Now to figure out the config.

miner received today. It came packed well and seems to be working but I dont know how to get into it to change credentials.  So until I do I guess qf420 is going to get some free mining done! LOL!  Haha. It's set up for DHCP right now, so find it in your DHCP client list, hostname should be miner. Then plug that IP into a browser window. syntax for config is like this: pool1=pool2=pool3 pool1worker=pool2worker=pool3worker pool1password=pool2password=pool3password Leave frequency at 800 and chips at 40. You can try 850 but my experience is that the increase in HW errors isn't worth the tradeoff for more hashrate. If you need to SSH into it use userid:pi, password:raspberry. I must be doing something wrong... I can ssh and connect to it but the password doesnt allow me in. When I try to connect to it via its IP address in a browser I cant connect at all. |
