This is how I'm powering mine. One 850 watt supply and several molex to (whatever the name of that power connector is) on the grid and were good to go. I have noticed that the grids dont like to be in close quarters when dual mining. They get pretty hot pretty damn fast. |

any chance these are going to drop in price since you can by a 750 ti for half the price and get 400kh per card?
Where you seeing 400khs per card? For the fun of it I put one in a computer last week and its hovering at closer to 200khs. It is only drawing 60 watts though!  |

Can I purchase a controller by itself or can anyone tell me if I can run my gridseed off my computer?
Its doable but you will only be able to mine scrypt and it will run at full power (BTC cores will be on) unless you run it on a Linux rig. In Windows you need to run CPUminer and install the right driver for the grid. You also need to make sure that the grid is in a single digit COM port number. There are lots of pointers within a few threads here. |

I must be completely stupid because I can NEVER figure out how to download files from this website. All I see are links that open up as web based text files and on and on... I can see a little further down where one can download a particular binary but what about the rest of the files? Do I have to download them one at a time? For the linux source, use git and clone it to you Ubuntu machine: sudo apt-get install git gcc make automake autoconf libcurl4-openssl-dev libjansson-dev
git clone https://github.com/gridseed/usb-miner/
cd usbminer/software/cpuminer
./autogen.sh
./configure
make
That will get you the minerd executable. Still have to run an instance per gridseed unit. Instead of a comm port #, you address them with the /dev entry. On Ubuntu 13.04, they showed up as /dev/ttyACM0, /dev/ttyACM1,....etc I'm glad that there are people like yourself out there that can explain this stuff to the layman like myself. I NEVER would have figured that out! Thanks!!! |

And furthermore. I wonder whats different about CPUminer in Linux that makes the Grids power down the BTC cores. I'd much rather stick to Windows mining if at all possible.

They will however mine scrypt @ ~9w if run them on a linux machine with the gridseed cpuminer -- https://github.com/gridseed/usb-miner/tree/master/software/cpuminerI had mine sitting on a table next to a GPU rig, got frustrated the setup on controller didnt work right for me, plugged the USB hub into the GPU rig, downloaded/compile cpminer, seems to work fine, stable so far around 300kh/unit. I had one running off a single PS and put my KillaWatt on it and it showed 9.0 - 9.1w while mining scrypt and finding blocks. I probably did something stupid/wrong on my the controller setup, will report back when / if I get it working. With more of these out in the field and the code on github, I'd expect that someone will put together some decent, clean control software. If you read some threads from other people selling, there are various issues with the speed, stability, and even malware with some of what people are getting. Now were talking! I've got a Ubuntu rig that I'm not using right now so this is perfect. Does cpuminer in linux have the same hangups with the double digit COM ports as the windows version? Do you still need to open a single instance PER miner? I'm totally trying this today! |

What about Gridseeds...are they for sale...?
Negatory Batman. |

How much are the 6870's?
Ah.... $125 each? They have been mining FOREVER but they have those Zalman coolers on the so they have been trouble free. |

As of now only the 6870's and the one 1000watt power supply have not been spoken for.

If I buy a stand alone single unit or two, is there anything else I will be needing?
Does a standard USB port/wall adapter power these?
It can only do SHA-256 with the controller? or is that going to be fixed soon so that units without the controller can do SHA-256 as well?
RIGHT NOW, they will only mine scrypt without the controller but they power up all cores and run at full power (again, without the controller). Std USB port will work but its got to be a single digit port (CPUMiner does not support double digit port numbers). A wall adapter would work but it needs to be 5AMPs or greater PER miner until they figure out how to turn off the BTC cores. You can probably run these things off of solar power with the BTC cores turned off! LOL!  |

One test bench, 4 Gigabyte Winforce (3 fans), 2 EVGA power supplies and 4 7970's are spoken for. I'll try to modify the original post to reflect....

I give up, how does one post pictures here???
It's best to use imgur. You then would upload the picture to imgur and then post the link here. It is the best method for posting pictures. Hope this helps! I tried that and ended up with that invalid image thing. I'll try again. |
