HOWTO: Run 50 gridseed miners off a single Windows 7 x64 machine-w/ downloads

[User705]

What's your total power draw?

I don't have a kill-o-watt, but I'm estimating around 8 watts per unit, or 393 watts. Not bad for 16 MH scrypt mining, if I don't say so myself.

How hot is the room they are in or how hot do they run? I have 2 miners with 6 total 280x cards and it is hot as hell in that room. I might order 20 of these to start. What site did you order from? Thanks for the great infor

Well, it's not hot at all. I actually disconnected the wires that cool these little guys and they are still cool to the touch. In fact, I had to turn on the pellet stove just a few minutes ago because it's cold down here.  I don't miss the heat and noise created by GPU's, I can tell you that.  I ordered from Zoomhash.com, he is totally legit and very helpful.

So just to be clear.  In LTC only mode these can run cool without bothering with all the power supply jumbo and just the powered usb hubs or did you only unplug the black fans on top of each unit?

Hello,

I have a quick noob question.

I am starting to use a few Gridseed units from Zoomhash. I have them plugged into a 10 port USB hub (Hoo too).

I loaded the virtual driver and cgminer (linked from Cryptomining). I can seem to get cgminer to see any of the Gridseeds, I can see them listed in the device manager as the virtual com port. I loaded the USB driver with Zadig . I changed the look time in cgminer from 0 to 5. Still no go. Plugged and unplugged usb port after cgis running also..

I then set everything back to default drivers and loaded Bfgminer, and it works from there, and suggestion what cgminer is doing different?


Thanks for taking the time to read.

Great setup. I have 23 running on one instance of cgminer. The ui hangs up though. Still mines but no data. Here comes the noob question. How do you setup several instances of cgminer for your gridseeds?

I want to konw
Why you put so many miner on the second floor?

How do you stop and restart them if using cpuminer with that many instances?

Is there a way to kill all the processes with one batch file or command? What I do, if I want to switch pools is to CTRL-C each instance, then I rerun the mine.bat file.

Anybody interested in buying raspberry pi + SD card loaded with hashra image? Have 3 available.

I figured it out. I use taskkill.

Code:

cgminer --scrypt --gridseed-freq  8D7415695554=975,6D8213764857=825,8D98206C4849=875,8D8B46874955=1150 --gridseed-options=baud=115200,freq=750,chips=5 --hotplug 5 --scan-time 1 --queue 4 --no-submit-stale

pause

This let's you specify each and every miner independently, with default  speed of 750 in this example.

This will let you specify exactly what speed to run that way you can minimize HW errors.

Oh, this only works on cgminer 3.7.2 (https://www.google.com/search?q=cgminer+3.7.2&sourceid=ie7&rls=com.microsoft:en-US:IE-Address&ie=&oe=)
