Hi all,

I just got two gridseed miners.

I've installed the drivers and both show up under 'ports' in device manager. One is on COM3 and the other is on COM4.

I am using cgminer to mine with and this is the command line I am using:

minerd.exe --freq=800 --gc3355=COM3 -o stratum+tcp://us-east.multipool.us:7777 -u user.1 -p pass.1
minerd.exe --freq=800 --gc3355=COM4 -o stratum+tcp://us-east.multipool.us:7777 -u user.1 -p pass.1

What is the command line to mine with both miners?

Thanks in advance,

Hello, did you try cpuminer-gc3355? https://www.dropbox.com/s/ttqa9p851siz8oi/minerd-gc3355.zip

Hi,

Awesome!!!

That did the trick. Both now mining away.

Thank you so much!!!

I spoke too soon.

I ran the miner and then went out for a couple of hours. When I came back the miners were flashing but the miner values were all 0. Frustrating.

I'm running Win7 64bit Ultimate Edition.

Any ideas???

Thanks,

Could you try the latest binary (same link), and let me know if there is any problems?
If they stop hashing, you could use "--gc3355-timeout=600", this will restart the GC3355 when there is no share activity in 10 minutes.

Well, it was a little more successful this time. After two hours one miner had accepted 1150 shares and continued but the other miner stopped at 764 shares.

I used the zip file you provided on dropbox.

Is my JSON config correct? Please let me know.

{
   "gc3355" : [
      "\\\\.\\COM3",
      "\\\\.\\COM4"
   ],
   "gc3355-freq" : [
      "\\\\.\\COM3:850", "\\\\.\\COM3:875:0", "\\\\.\\COM3:900:3",
      "\\\\.\\COM4:900",
   ],
   "gc3355-autotune" : true,
   "gc3355-timeout=300" : true,
   "pools" : [
      {
         "url" : "mypool:7777",
         "user" : "myusername",
         "pass" : "mypassword"
      },
      {
         "url" : "mypool:7777",
         "user" : "myusername",
         "pass" : "mypassword"
      }
   ],
   "freq" : "850",
   "debug" : true
}

Thanks again for the help.

thats not cgminer batch thats cpuminer....

Btw I run over 40 G-Seeds with Cgminer with no issue... All of mine are overclocked Voltmodded3 and run each @ 510KH/s

here is my batch

cgminer.exe --scrypt -o stratum+tcp://us.clevermining.com:3333 -u USERNAME -p x --failover-only -o stratum+tcp://sf.clevermining.com:3333 -u USERNAME -p x --failover-only -o stratum+tcp://ny.clevermining.com:3333 -u USERNAME -p x --failover-only -o stratum+tcp://useast.wafflepool.com:3333 -u USERNAME -p x --failover-only -o stratum+tcp://uswest.wafflepool.com:3333 -u USERNAME -p x --failover-only -o stratum+tcp://sea.wafflepool.com:3333 -u USERNAME -p x --gridseed-options=baud=115200,freq=1200,chips=5 --hotplug 5

pause

see how many failovers I have? :) All these servers will have to go down for my miners to stop
