[GUIDE] GridSeed GC3355 5 Chip Setup/power/windows/linux/rpi by UnicornHasher

[Shivoreun]

Hi to all.
Please, help me to solve a problem with GC3355. The miner is working unstable and with extremely low hasrates, 50-70Kh/s instead of 350 in scrypt-only mode, as it have to. Used several miner softwares, but the results are the same. Running on windows xp with usb driver from here. The power setup is: usb cable connected to motherboard usb port of PC, the external power is connected to the same PC's PSU via molex connector, which was in the box with ASIC.



At the start, miner says:

It's starting to mine, with such low hasrates, sometimes it dies after 10-15min of working with the UART write error message, sometime working OK for a few hours... Please, help me to get normal hasrates. What I doing wrong?..
Thanks in advance.

It seems that you are using only one chip instead of five. Try official not modified mining software and cgminer may be

Use BFGminer 4.10, uninstall your drivers, unplug your gridseed, plug it back in and let it install the correct drivers, find the COM number of the gridseed (under Start Menu>Devices and Printers), and create a batch file that has:

bfgminer.exe --scrypt -o stratum+tcp://pool:port -u username -p password -d gridseed -S gridseed:\\.\COMX --set-device gridseed@\\.\COMx:clock=875 and you're good to go!

Hmm.. I've tried to find original software, but looks like it's only in sources, thet need to be compiled byself Is there any link for already compiled win32 binaries, please? Unfortunatelly, I'am a windows user, and don't know, how to do this...

Bfgminer hashing with correct hasrates, but... Accepted rate as extremely low (not because of rejected, there is it's simply low count of submitted shares). The most of the time I see a messages, that there is detected new block on the network, so miner need to restart work, I think, that's because of high difficulty, that bfgminer automatically takes, from 488 to 1m.

As you can see, there is a lot of rejects, because ASIC cant' hash workunit in time, and sending stale shares. Of course, I can turn off stale sending, but this will not solve an overall problem presence

Is there any solution for this?

BTW: I saw on the forum, that there is need to do correct power-up the GC3355, so firstly, it's need to plug-in USB, then wait for 30 secs and plug 12V ext. power. Is this correct?

BTW2: After a few minutes from this message there was a ban from pool side "worker is temporaly banned". I think, because of rejects

[slashka]

Well, try RaspberryPi (I can help you, PM me). It ~30 bucks Windows is suxxx in mining

Powering them up isn't really that hard.  Plug in the power first, wait a few seconds, then plug in the USB.  The other way around confuses the gridseed.  I bet that it's trying to power itself from the USB and is disregarding the actual power.

1. Make sure you have a minimum 5 Amp, 12V power supply for the gridseed.  Lack of power will be bad for your miner.

2. Try a different pool.  It could be that the pool you're running on is just a crappy pool.  I've experienced this a few times with my gridseeds.  Try using multipool.us (they have EU servers available) or if you want to see what difficulty you should be running at, try liteguardian.com and use the asic1 server to auto tune the difficulty.  Once it evens out, you will know what difficulty you should be running it at. 

3. Make sure you're using a low enough difficulty.  Otherwise it will take a while to hash out a share.  I've got 3 of them running together and they generally try a scrypt difficulty of 64 or 128.  Sometimes if they're doing well, they bump up again.

4. If you have a crappy internet connection, that could also cause a problem.

Hmm... The PSU, which powering Gridseed have 18A output on +12V lines and 0.8A on -12V, Is it enough?
The pool is working fine (anyway, I've already tried different pools and another scrypt coins), there 2 x HD7970 mining at the same pool with different workers (Gridsees has it own worker set up on pool), so this is not an issue, I think...

I can't for the life of me get this to work. Anytime I get to the "make" stage it gives the following error:



I've tried reinstalling GCC, different versions, etc. nothings working. I basically have a worthless gridseed. I've spent close to 10 hours just to get this to work, and another 15 hours on my RockMiner New RBox.

Did you look in config.log for more details? It should tell you exactly why it failed.

One thing that stands out for me is the CFLAGS -02 parameter (zero two). I think it should be -O2 (capital oh two).

Looks like you're right. CPUMiner compiled. Running into an issue with CGMiner though, ./autogen.sh appears to not exist in the ~/usb-miner/software/cgminer folder.

Pretty sure I got it, the only issue is it's running at 250KH/s thought it was supposed to be 340KH/s (could be freq thing, think it's set to 600). And second I'm connected to HamsterPool but I see no hashing information on the website.

This is what I'm seeing:

Yep, 600 would do that to you. Try

--gridseed-options=freq=800,chips=5

in the command line, or

"gridseed-options": "freq=800,chips=5",

if you're using a config file.

[coconutter]

Hi guys! I'm sorry for bothering you, but I'm having unexpected hard time trying to mine in different pools and...well, I'm seeking help

So, first things first, this is my hardware:
1 raspberry pi mod. B
2 gridseeds mini (I use them in scrypt mode)

About the software, it's debian wheezy with the following:

ssh back in as miner and install the pre-requisites

Code:

sudo -s
apt-get update
apt-get install -y build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake screen
exit

Build cgminer:

Code:

git clone https://github.com/gridseed/usb-miner/
cd usb-miner/software/cgminer
autoreconf -i
./configure --enable-gridseed
make

Build cpu miner:

Code:

cd
cd usb-miner/software/cpuminer
./autogen.sh
./configure
make

Link the build directories for convenience:

Code:

ln -s ~/usb-miner/software/cpuminer ~/cpuminer
ln -s ~/usb-miner/software/cgminer ~/cgminer

and at this point I'm all good. But here's my problem: if I try to run both the gridseeds in the same stratum pool&worker they run fine, but I can't figure how to make them run on 2 different stratum pools!
reading the awesome OP's guide I thought this would work:

How I run the 10 miners to 10 separate pools:
***WARNING: This assumes you use username miner and home path /home/miner ****
This also assumes that you have added your user to plugdev or are using root with (sudo -s)

1) Create 10 pool files named pool0.sh to pool9.sh
2) insert the FREQ NAME and POOL variables into each pool file
pool9.sh

Code:

NAME="miaviator"
POOL="-o stratum+tcp://middlecoin.com:3333 -u 13zKJjzxGpjbqJDAWAhFNHVqALqcsCWiat -p x"
FREQ="800"

3) make the mine.sh script to execute the miners

Code:

cat > mine.sh << EOF
count=0
for i in `ls /dev/ttyACM*`
do
source /home/miner/pool$count.sh
cd /home/miner/cpuminer/
screen -dmS $NAME ./minerd -F $FREQ -G $i $POOL
count=$((count+1))
done
EOF
chmod +x mine.sh

After running mine.sh for this hosting thread https://bitcointalk.org/index.php?topic=471764.0 I have the following screens:

I've created 2 files, pool0.sh and pool1.sh with pools' details, and mine.sh.
But it doesn't work for me!  
also I've noticed that in the "mine.sh" code it uses CGminer syntax, while it's executing CPUminer (./minerd)...
so I've tried changing the folder and having it executing ./cgminer,
but once I run "mine.sh" it doesn't do anything, only the "chmod +x mine.sh" command resulting in this:
*instead of home/miner/ I use home/pi/ as default*

Code:

count=0
for i in /dev/ttyACM0
/dev/ttyACM1
do
source /home/pi/pool.sh
cd /home/pi/cgminer/
screen -dmS ./cgminer -F  -G 
count=1
done

when I run it and then "screen -ls", it says that there are no screens-blablabla, so there isn't any cgminer instance working  
similar results using cpuminer...

I can't figure out what I'm doing wrong! Does this "multipool method" work only on linux (Part 5A.1: Linux) but NOT on the raspberry?  
Is there anyone able to help me?  

Thanks for the patience...

Hi, how do I run cgminer for a specific gridseed device? I have 2 gridseed 5 chips. GSD 0 and GSD 1 appears, how do I cgminer to run GSD 0 on one pool, and cgminer GSD 1 on another pool? I have cgminer 3.7.2 downloaded and already tried -d 0, -d 1 doesn’t work. Thanks

You have to run 2 instances of CGminer to let each unit hash separately, or run them both, add the second pool and use something like load balance.  It won't be the same though as running 2 instances of CGMiner

[ntrader]

Thanks, I know about  2 instances of CGminer, but I dont know which command I need to use for separation that gridseed asics

I know with BFGMiner, you can specify which gridseed to use by selecting the COM port it's associated with.  I think for CGminer (it's been a while since I've used it) you can select just 1 gridseed, using something like --gridseed=\\.\COMx to select that specific gridseed.  Then open the second instance and use the other com port that the other gridseed is attached to.  I can't remember exactly how to run it because I use BFGMiner and Luke-JR answers those questions super fast.

I need to disable the fans from a Gridseed I have here... Can the wires simply be cut and "sealed" with isolating tape?
