Running more than 2 Gridseeds on Windows 7 with cgminer causes the program to crash
Is anyone running cgminer on Windows with more than 2 gridseeds successfully?
I have four gridseeds running with cgminer on windows 7. |

$1.00 per Kilo Hash to get 800KH/s performance
 Again with your random shit masked as facts. By your logic people should have been buying R9 280X for $750 and R9 290 for $900, it was nowhere near that price point even at the height of the boom. More realistically you would have paid $0.5 or less per KH/s, including all supporting infrastructure - motherboards, risers etc. If someone was stupid enough to pay $1.0 per KH/s of GPUs then the same kind of people would be buying Gridseeds on eBay for $350. I love Gridseeds for their relative simplicity, price however is not their strength. Especially with the recent drop in GPU prices. Just to throw it out there... that $1 per KH/s must also include your supporting infrastructure as you mentioned... mobo, RAM, CPU/HSF, HDD/SSD/USB depending on how you are running them, PCIe extensions, the 1200-1600W PSU you need to run 4+ cards if you are doing so and all the extra connectors you need to run cards that require more than a single 6 pin PCIe power connection. A single 800+ KH/s GPU running $500 - $750 still needs $100+ just for a basic mobo/CPU/RAM/BOOTDISK/PSU and that's cheaping out... you can easily reach +$200 for a base PC to run the GPU... and more if you want to run a multi GPU rig. Tell me where I can get an 800 KH/s rig for $400 ($.5 per KH/s) and I will delete this post. Hell the highest noted GPU on the scrypt litecoin comparison wiki is the Sapphire Tri-X 290X at 1002 KH/s and that's on Newegg for $750 right now and is noted running at 385W. A new setup could easily run $1000 to get that 1 MH/s running stable, whereas $1000 will buy you 3 gridseeds, a Pi, PSU, barrel jack connectors, a powered USB hub and some sort of case to put it all in, gives you a MINIMUM 1150 KH/s AND only runs a total of ~30-35W max in scrypt mode including hub and Pi. Compare the GPU rig running ~500W total to a 35W 3X gridseed/Pi and still get 15% more hashrate for 1/14th of the power cost... and probably still have funds left over. For $.10 per kWh that is ~$400 a year less in cost of power. So while you may be able to resell that GPU for $400+ next year... that only brings you to break even with the gridseed setup... before the extra 15% hashrate is included. |

Don't get me wrong, I love the gridseeds, but gpu's have quite a bit more versatility than asic for scrypt. When scrypt asics become more popular, asic resistant coins will start popping up (execoin, vertcoin) so people with gpu's can still play. And if crypto coins go away at least you can resell gpu's. That being said I'm getting rid of my gpu's because I don't want to spend thousands upgrading my electrical service and installing improved cooling just to have a decent sized farm. |

I don't think script coins will dissapear, there will always be people making pump and dump coins. Little question about USB hub, what's a good usb hub than can hook up to the laptop and work with the gridseeds, I've heard some hubs have issues |

I couldn't see the hub you sent me in your link, somehow the page shows up weird in my browser. well as long as I can put 4 in there and it works on the laptop it's fine. whill be handy too as there are only 2 ports on this thing. 1 usb2 1 usb3 |

you says this:

Code:
sudo -s
apt-get update
apt-get install -y build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake screen
exit
but then on the next step you don;t tell me if I should login as root, miner, who exactly and should I ssh in or do this from the console and WHO should I do this as?
thanks
You would already be logged in as miner if you did sudo -s entered your password and then typed exit. The exit command would take you from sudo (root) back to user (miner) ps: I also got this and I'm stopped dead following the directions:

insserv: warning: script 'mathkernel' missing LSB tags and overrides
Everything I can find says that is a warning and should not stop the process from working. I never got that warning when I did the installs. Try to keep going? or did the process not complete? |

So I found the limit of gridseed devices you can run on the Pi. That limit is 32. Not because the processor isn't fast enough, but because the serial to usb driver that it uses only supports 32. The other devices are seen by the Pi but it does not assign them a ttyACM address and therefore cannot be used.
Unless there is a workaround, 32 is the magic number!

Tell me where I can get an 800 KH/s rig for $400 ($.5 per KH/s) and I will delete this post.
You don't build 800 KH/s GPU rigs, a typical rig of the past couple of months would be 6x R9 270, and it can do ~2.8 MH/s. Cost ~$1100 for GPUs plus "infrastructure". Before R9 280X prices went crazy you could build a very nice 6 GPU 4.5 MH/s rig for $1800 + "infrastructure". Now prices seem to be coming back to normal, so that could be possible again. There is also the GTX 750 Ti, not as cheap in $ per KH/s, but much more power efficient, somewhere in the middle between Gridseed and AMD GPU. There is no need for a massive expensive PSU, two mid-range 600-850W PSUs will do nicely and will be cheaper. There is the ASRock BTC motherboard available for ~$70 (6 powered PCI-Express slots). Cheapest CPU and RAM will do just fine. HDD is not necessary, a $10 flash drive runs BAMT. The point is, you can overengineer and overspend on any solution, but a well though out GPU rig does not come even close to $1 per KH/s AND is a lot more versatile than Gridseeds (think Vertcoin or Heavycoin). On the other hand, you can put a handful of Gridseeds on your desk and have 1.5 MH/s literally in minutes. Each has its benefits if you know what you're doing. |

On the other hand, you can put a handful of Gridseeds on your desk and have 1.5 MH/s literally in minutes. Each has its benefits if you know what you're doing. Just a few months ago, when, after looking over ALL the options, GPU's were overall much more expensive than GridSeeds, and on average still are. Especially where power consumption and maintenance go. They are also noisy, cumbersome space heaters! At that time, $1 per Kilo hash for a top of the line GPU was conservative! No matter how cheap 500KH/s etc. GPU's can be had, they will always be grossly power hungry by comparison! This is a MAJOR factor in itself! The more one spends on Kilo Watts, the less money one puts in their pocket! Period! No matter what anyone says, no matter the calculations and rationalizations, GPU's are still and always will be more expensive to own and operate than ASIC's. Namely, GS5's - Period, end of story.... To be fair, the only 'obvious' advantage a GPU has over ASIC's is Algorythmic versatility! Then again, FPGA's are Algorithmically versatile as well and just as efficient as ASIC's. Just not as commonly available as GPU's, unfortunately. But that is changing in due course! GPU is a fancy video card that has it's primary and original purpose completely circumvented by use as a miner. That use goes completely to waste! POOF! No such off purpose waste with ASIC's or FPGA's. NONE! Overall, I just can't justify using a GPU over GridSeeds. What ever processing speed GPU's have over GridSeeds 1 for 1, is completely negated by the overall efficiency thereof! GPU's are a dying technique headed for the status of relic where mining is concerned. They are headed back to doing only one thing. Driving LCD's! That is who GPU owners will be selling their used video cards to in the future. GAMERS!  Wolfey2014 |

ok - got the compile and makes done - and got names of all 20 gridseeds
now:
root@raspberrypi:/home# sudo ./minerd -F 850 -G /dev/ttyACM0 -o stratum+tcp://us.ltcrabbit.com:3334 -u xxxxx.1 -p 123
sudo: ./minerd: command not found
ugh!
confused - this is shown at the top of the thread.
the commands are the same for two different programs?
how does it know which one to run?
Now run the miner process:
Code:
sudo ./minerd --freq=600 --gc3355=/dev/ttyACM0 --url=stratum+tcp://middlecoin.com:3333 --userpass=13zKJjzxGpjbqJDAWAhFNHVqALqcsCWiat:x
Or using CGMiner Syntax
Code:
sudo ./minerd -F 600 -G /dev/ttyACM0 -o stratum+tcp://middlecoin.com:3333 -u 13zKJjzxGpjbqJDAWAhFNHVqALqcsCWiat -p x

You're in /home, you probably want to do cd /home/miner or wherever your minerd is located. Then run it. |

AFAIK, Pi is supporting only two "levels" of USB chaining. Meaning that if You have 7-port hubs that have all 7 ports in one level (not chained internally) You can run 49 GSDs per port using 8 hubs, or 98 in total with Pi + 16 hubs. I think You have connected only 32 GSDs in first 2 levels of Your usb chain... |

All the talk about power costs is one of the reasons im switching to GS5s. The other is air-conditioning. I live in the Arizona desert, and it's already getting hot enough that I have to dial-back my GPU rigs to between 8-13 intensity from noon to 9pm because of the heat. The GPU's ran fine all winter in my garage, but now it's getting ridiculous to try and maintain them in that environment. Moving inside isn't going to be acceptable from a noise perspective.
I suppose I could go out and buy rack-space at some co-lo, but that would eat into the revenue stream.
For me, I pretty much have to move to ASIC because I won't be able to run the GPUs effectively during the summer months.
