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

[thevictimofuktyranny]

Hi

So i have 2 Gridseeds, and am using CGMiner for them to hash in SHA256 (at around 12.5GHS total) and CPUMiner for Scrypt (at around 600mhs total) - Connected to a Windows 7 PC.


I've read they should be able to hash upto 11GHS each in SHA256 only mode, but i can't figure out how to get them upto those speeds in SHA256 only?

Any advise?

Thanks

Hi, you need to overclock them and simply not activate the cpuminer (scrypt) side of the device.

Apparently, when the sha cores are hashing and LTC core are hashing they limit each others speed.

The max Dual core speed is 750mhz, however scrypt only mode will runs stably between 850/900mhz (depending on the quality of the chips). Apparently, the same speeds applies to the Sha core 850/900mhz (depending on the quality of the chips).

Very few people are dual mining and software is pretty ropey and crashes a lot. Nearly all the work on forum's contributors has gone into the Scrypt only option (Sandor111 has produced an excellent cpuminer at moment).

You may want to open up your gridseeds and check the thermal pad is touching all the Gridseeds chips (use a dab of MX-4 thermal paste or something else that is a non-metallic paste).

Secondly, after installing the stsw-stm32102 and before install the Zadig drivers - go to device manager. Select "Ports" and "Properties" and "Advanced" setting. Unselect the Fifo Buffers and you get longer runs in dual mode before needing to reset. Then you can install the Zadig drivers.

The overclocking/voldmodding is on this link:

Hello to all the bitcoiners, im here praying for some help, the problem is related with BTC mode in a gridseed.

The same proble in Linux and Windows, i have an Asus P8H67 mobo with an Intel G1620, 4GB of RAM and a AMD 5970&7870, i also tried dual mining with a Gigabyte Z77X-D3H with an i5 2500K and a venerable 8800GTX. I tried with Ubuntu 12.04.2 and Windows 7 Ultimate, 64bits both.

I managed to mine scrypt on both PC with windows but BTC/dual mode is imposible, again and again cgminer throws me an LIBUSB error, i googled a litle bit but the LIBUSB web dont give me any kind of help. Im using this guide with the cgminer suggested, im stucked here by since last thursday. If someone is capable of help me with this i will send him a bounty

I have to append that gridseed is plugged in a USB2 port, i tried to connect to differents ports and i run cgminer with sudo comand.

Issue : Miner cant connect to P2P Nodes

Miner connects to normal pools w/o Problems, but on P2p we have a stratum auth failure.

Issue : Miner cant connect to P2P Nodes

Right, so this is the best version of cgminer for modded gridseeds.  However, P2Pool mining is broken for this branch of cgminer-gc3355:
https://github.com/jmordica/cgminer-gc3355

To fix it you need this older branch (that doesn't support freqs above 1150):
https://github.com/girnyau/cgminer-gc3355/

Then you'll build the old branch, but first:

1) From the new branch, copy the driver-gridseed.c, and driver-gridseed.h into the old branch.

2) In the old branch, open miner.h and add the following code beneath line 1048:

extern char *opt_gridseed_freq;

3) In the old branch open cgminer.c and add the following code beneath line 178:

char *opt_gridseed_freq = NULL;

AND the following code block at line 1053:

static char *set_gridseed_freq(const char *arg)
{
        opt_set_charp(arg, &opt_gridseed_freq);

        return NULL;
}

After that, while in the directory for the old branch run:
./configure --enable-scrypt --enable-gridseed
make

And then you should be all set with high frequency support for P2Pool on your modded gridseed!

hi  , im trying to use gridseeds 5 chips (dualmining) with antminers u2 , but cgminer freeze at start, the only way to work is unplug the antsminer, start mining with cgminer with gridseed  and cpuminer for scrypt , and after that plug the antminers and and use bfgminer with the antminers, any way to use the cgminer for mining with both? or a command to avoid the unplung of the antminer to start the cgminer.


thanks in advanced for the help

Hi guys,

Will be great if someone could help with this one as I can't find any threads that lead to the problem.
Got the Gridseed GC3355 set up and got it mining in scrypt mode and BTC mode in Ubuntu.

When I then try dual mode with:

cd usb-miner/software/cpuminer
./minerd --freq=800 --url=stratum+tcp://stratum.scryptguild.com:3333 --userpass=xxxxx:xxxxx --dual

it gets stuck while trying to communicate with the server

Stratum detected new block
[2014-06-05 21:40:08] 0: Dispatching new work to GC3355 LTC core

While it's doing this the gh/s rate goes up in the terminal in BTC mode (from around 6ghs to 11ghs) but the connection's immediately lost with the pool I'm mining BTC on (BTC Guild).

Have I installed something incorrectly along the line or am I using the wrong pools?

Help me Obi Wan's, you're my only hope...

I was having the same problem , when i start minerd the cgminer  stop the comunication , i really didn't isolate the problem but i fixed using a hub with hight power supply, and changing the power supply  of the miners , the one i was  using was reporting voltage  under 12v. i hope  you can solve the problem

Edit - Got it working now, thanks anyway.

so it could be power supply! this makes sense. I've actually got a power supply that's got six connectors so maybe it's losing power somehow...

thanks for the suggestion.

This doesn't work for me with GridBlades: the "old" patched version is running at an extremely low hashrate (and from what I see, it misses fixes for number of chips, which explains it...).

Instead, it looks like the regression in the jmordica branch was introduced in the commit added support for NiceHash.com, I don't have much time to check what is wrong with the new code, but pulling the repository just before that and compiling it works fine for me (good hashrate+connection to p2pools). In case others are interested (but you obviously won't be able to mine at NiceHash.com... maybe it's better than not being able to mine at *any* p2pool ), here is the recipe I followed:

Code:

git clone https://github.com/jmordica/cgminer-gc3355/
cd cgminer-gc3355
git checkout f20c066127a843cc75b79a3a29f80cf890341ec6
./configure --enable-scrypt --enable-gridseed
make
./cgminer --script ...

Hello to everybody,

I have 2 GridSeed and I am trying to install it on my RaspBerry (using RaspBian) following the instruction founded on this post but I am finding some problem.

I have download and build cgminer and cpuminer and it seems to me that this process gone ok (I had no error).

By ssh I done the following steps:

1) Enabled the root account:

Code:

sudo passwd root
***
***
exit

2) ssh back in as root and change the associated paths and groups:

Code:

usermod -l miner pi
usermod -m -d /home/miner miner
groupmod -n miner pi
exit

3) Builded cgminer:

Code:

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

4) Builded cpuminer:

Code:

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

Now my doubt are: where these softwares are installed? in the same directory where I builded it or where? I am not so sure that I have correctly installed the software because I have the following situation:

Into the cgminer direcotry I can find the following files:

is it possible to run one instance of cgminer with both 5chip and 40chip gridseeds?

I am really curious to know and would be great if you can

[nev_dull]

D4rkAng3l, in the listings you posted below I see the cgminer binary compiled in the cgminer directory and the minerd (cpuminer) binary compiled in the cpuminer directory.
When you build (compile) something it doesn't delete the source code-- it will all still remain there unmodified, except you will see additional object files (.o) from the compile process as well as the resulting binary.

To run those you need to specify the path to them, for instance ~/usb-miner/software/cgminer/cgminer or if you are already in the cgminer directory specify ./cgminer

If you wanted to install them elsewhere you could add --prefix=/opt/cgminer (for instance) to the ./configure line and then do a "make install" to have makefile create /opt/cgminer and install the binaries in there.

is it possible to run one instance of cgminer with both 5chip and 40chip gridseeds?

I am really curious to know and would be great if you can

anyone have an idea?

[WheresWaldo]

can someone help me finding a guide on how to run 2 instances of cgminer and determine which one runs the gridseed minis and which one runs the blades?

will even tip if I have to, other threads not being any help

Are you using Windows, Linux, ... ? Typically you would just start it the way you normally do, just use different config files for each instance, and specify your devices.

On Linux its something like this:

"usb": "1:5,1:6,1:7"

where 1:5 etc is bus:device number. Use "lsusb" command to find these numbers.

On Windows it might be tricky because cgminer tends to need hotplug but normally devices keep the same port number so it could still work. Use Device Manager to find COM port numbers.

where 1:5 etc is bus:device number. Use "lsusb" command to find these numbers.

On Windows it might be tricky because cgminer tends to need hotplug but normally devices keep the same port number so it could still work. Use Device Manager to find COM port numbers.

i will try this out thank you so much!!

I really appreciate this, I've been looking around for quite a while, props to you suchmoon!

can someone help me finding a guide on how to run 2 instances of cgminer and determine which one runs the gridseed minis and which one runs the blades?

will even tip if I have to, other threads not being any help

Are you using Windows, Linux, ... ? Typically you would just start it the way you normally do, just use different config files for each instance, and specify your devices.

Hey Waldo, did you ever get this to work? I'm trying to configure a similar setup. I was looking at the cgminer 3.7.2 Gridseed ed. readme, and it says you can individually set the frequency for each gridseed unit, and I'm curious if you can also edit the number of chips for each device as well.
