Have you considered running it as a service? Would certainly clean things up if you actually want to continue using that computer while mining! (not to mention you don't have to worry about when the computer crashes and/or reboots while you're away).

That's a good idea. I am not much of a windows guru, so I'll have to look up how to do that. Will there be a way to monitor random miners here and there if it's running as a service?

VERY HELPFUL I forgot that batch file trick in passing the variable.

Also your hashrate looks a little slower that I had expected it to be, although I don't know whether you are running all 50 but 15Mh was what I would expect

Here are some things you’ll need if you just have the gridseeds but didn't get the kit:

wire to connect power:

barrel connectors: http://www.amazon.com/gp/product/B0058RLD9C/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1

Anger is a gift.

Awesome. Fed-Ex just delivered my 20 pack, now I just have to try and sneak out of work for a few hours to get them going.

Then once you've gotten this done, you need to create a couple scripts that will help you run the cpuminer instances.

first, called mine.bat:

Code:

echo on
miner-start.bat stratum+tcp://us-east.multipool.us:7777

The next one, called miner-start.bat. Note--if you are running more than 10 COM ports, you'll need to slightly modify the COM designation in the script from COM12 to \\.\COM12.

Code:

start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM2 --url=%1 --userpass=zeetak.1:x
start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM3 --url=%1 --userpass=zeetak.1:x
start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM4 --url=%1 --userpass=zeetak.1:x
start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM5 --url=%1 --userpass=zeetak.1:x
start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM6 --url=%1 --userpass=zeetak.1:x
start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM7 --url=%1 --userpass=zeetak.1:x
start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM8 --url=%1 --userpass=zeetak.1:x
start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=COM9 --url=%1 --userpass=zeetak.1:x
start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=\\.\COM10 --url=%1 --userpass=zeetak.1:x
start C:\Users\zeetak\Desktop\cpuminer-GC3355-win32-fixed\minerd.exe --freq=850 --gc3355=\\.\COM11 --url=%1 --userpass=zeetak.1:x

Now when you run mine.bat, you'll open up xx instances of minerd and will start hashing away. My next step is Windowskey-D to minimize everything, then maximize just the windows you need. As you can see, the amount of system resources it is using is hardly any, so it shouldn't be a problem to run 50 instances on your desktop:

I've been able to get my 48 miners powered by a single windows x64 machine. I was using anker 13 port powered hubs and I found that you can't daisy-chain them, as windows sees each block of 4 ports as a daisy-chained "hub."

Basically, you need to plug each hub into the machine or, at the very least, daisy-chain off the first port. Here is my current setup, minus a few gridseeds.

When I initially plugged these units in, I couldn’t get windows 7 x64 to see the virtual com ports, and found I needed to install the virtual com driver that I found here: http://www.diffpair.com/lightningasic/LIGHTNINGASIC%20Gold%20miner%20USB%20driver.rar

I’m running separate instances of the custom-coded cpuminer with the BTC core shut off for scrypt-only mining. I was able to get that from here: http://cryptomining-blog.com/1165-download-cpuminer-for-gridseed-5-chip-gc3355-asics-with-reduced-power-usage/

I have been able to get about 16 mh when mining with 49 of these units. I’ve been running them for 48 hours straight now with no disconnects, no reboots, and 100% stability. If you are having issues with the supplied controller, I suggest you ditch it and use a computer. If you’ve still got motherboards lying around from your GPU mining days, setup a quick install of windows/linux and run your gridseeds off that.
