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

[Ferris419]

https://github.com/siklon/usb-miner/tree/master/software/cpuminer

Short summary:
* Added hashrate statistics
* Added auto per-chip frequency tuning
* Added JSON API at port 4028 -> send {"get":"stats"} to get stats for each miner/chip
* Input any frequency you want

Code:

 -G, --gc3355=DEV0,DEV1,...,DEVn      enable GC3355 chip mining mode (default: no)
  -F, --freq=FREQUENCY  set GC3355 core frequency in NONE dual mode (default: 600)
  -f, --gc3355-freq=DEV0:F0,DEV1:F1,...,DEVn:Fn      individual frequency setting
  -A, --gc3355-autotune  auto overclocking each GC3355 chip (default: no)

It should work on Rpi, but I haven't tested it yet.

im looking for this cpuminer compiled for windows can someone point me to a place to download it? thanks in advance

look a few post up, sandor is the one that made it and the link is in his signature

duhhhh!!!!!!! dont know how i overlooked that! Thank you!!!!

Ok so I downloaded the CPUminer for windows from Sandors signature but I can't figure out how to use it? I've been reading and reading and reading with no luck .... I have 14 gridseeds all have the 49.9k mod I can't get them to work with CPUminer all I get is dispatching new work to GC3355 threads <0x5f1b8182> if some can give me a sample .bat setup for auto tune I would highly appreciate it!!!!!!

this is how I run them, I have previous version of sandors cpu miner, new one has some extra features but it should get you up running

minerd-gc3355.exe --gc3355=\\.\COM7,\\.\COM8,\\.\COM9,\\.\COM10,\\.\COM11 --gc3355-autotune --freq=1100 --url=stratum+tcp://xxxxxxx:xxxxxx --userpass=xx.xx:x

so replace the coms with yours etc.. you know the drill I think

so replace the coms with yours etc.. you know the drill I think

where can i see my com port numbers? when i look in device manager all i see is STM32 Virtual COM Port for all of them?

******edit i figured it out and it seems to be working but im confused how i can see my actual speed in cpuminer? im used to cgminer... ugh i feel like a total noob all over again

***edit again dont really know what im looking at and im trying to decypher it but it looks to be running a hell of a lot better than cgminer was.!!!

have you been runing CGminer before? cause if you did you changed the drivers with zadig and do a manipulation to uninstall those and re install
the proper drivers

Is there a way to make the 5 chip units start using CGMiner on Windows without having to start CGMiner and only then plug them in?

This often leads to issues of them not being picked up and this arduous process having to repeat itself multiple times until CGMiner identifies all of them.

Anyone?

I have 10 GSDs under a Raspberry Pi running the mox235 variant of cgminer (like girnyau, but with improved JSON output). I've been using Scripta, which does a decent job of presenting stats. But it doesn't seem to display discards.

I dumped the JSON summary from cgminer this morning. It tells me that I've had 8038 discards (under the "Discarded" key) in a little less than 16 hours. During the same period there were 5866 accepts, 37 rejects, and 24 hardware errors (I have a crappy GSD that I have to under clock to get any utility out of it). Local hash rate for the 10 units averages 3.61 Mh/s.

This was with the rig pointed at wafflepool. I'm getting a utility of 6.16 with that pool.

My question is whether these numbers are reasonable for GSDs on a multi-pool like wafflepool? Searches elsewhere indicated that having a high number of discards is not normal for GPU rigs. But I have no idea what is normal for GSDs on pools that switch coins.

I've searched for quite a bit, but is there a way to limit the number of Gridseed devices per cgminer instance in Windows? Say, calling devices 0-9 only per instance would be ideal. In testing my units average a higher accepted share rate when split amongst multiple instances.

A word of a apreciation from me to all who contributed in the set up of Gridseed miner


Followed the instructions
1) downloaded BFGminer for Gridseed
2) donwloaded and installed stmp drivers
3) fixed my bat file with my settings

then I first istalled the USB cable on the computer without applying power
to the miner and saw that the computer recognised the miner and gave message your
device is ready to use.
Connected power

then run the BFG miner but will not hash..... a quick look on the bat file showed a fat fingers typo
then correction and run the BFG again...hashing since 12 hours now....

Great job thanks

[nabeton]

Yeah, thanks for this thread.

I've succeed in setup Gseed dual mode, mining for 12 hours, using wired molex and I get 7+ Ghs, 300+ Khs.
Now catching up how to reduce HW errors, but still glad I did it.

Definitely, I have to get few more of these "G-units"

It does not support dual mining. Maybe we should get a fund together to have him work on a dual mining version?

That works properly. Thanks!

Hi there!
Uh... reading the post looks like I might have gotten into something bigger than what I can handle but I still want to be part of this.

I'm in UBUNTU 13.10 and I don't seem to be able to get past the building cgminer step:

Build cgminer:

Code:

cd ~/usb-miner/software/cgminer
./autogen.sh
CFLAGS="-O2 -Wall -march=native" ./configure --enable-gridseed
make
cd

whenever I type ./autogen.sh it prompts:
bash: ./autogen.sh: no such file or directory

Any ideas why this happens?

Try to figure out where you are:

pwd

ls -al

ok hers what i did



ok heres what i did
make sure you are sudo su to root
cd   
apt-get install build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake screen
wget http://curl.haxx.se/download/curl-7.34.0.tar.bz2
wget http://www.digip.org/jansson/releases/jansson-2.5.tar.bz2
tar -xvf curl-7.34.0.tar.bz2
cd curl-7.34.0
./configure
make
make install
cd ..

tar -xvf jansson-2.5.tar.bz2
cd jansson-2.5
./configure
make
make install
wget http://ftp.osuosl.org/pub/ubuntu/pool/main/a/automake1.11/automake1.11_1.11.6-2_all.deb
sudo dpkg -i automake1.11_1.11.6-2_all.deb
sudo ln -s /usr/local/lib/libjansson.* /usr/lib/
cd ..
git clone https://github.com/jmordica/cgminer-gc3355
if you have a problem with git then use  'apt-get install git'
cd cgminer-gc3355/
./configure --enable-scrypt --enable-gridseed
make

Thats it your done
./cgminer --gridseed-options=baud=115200,freq=800,chips=40,modules=1,usefifo=0,btc=0 --hotplug=0


this works on Ubuntu 13.10  and the new version 14 Ubuntu

Hope this helps you out.

can anyone point me to the latest scripta image that works with the 5chip ?

[thevictimofuktyranny]

Hi, I'm really new to ASIC devices and mining coins. I can't seem to find any proper manuals for the Gridseed miners!

1) Are there any special instructions for cgminer (windows version from cyrpto mining blog) to mine other SHA256 coins in dual mode with Scyrpt.

2) I was interested in mining Continuum coins and noted a BTC=16 instruction. Is this instruction a worksize instruction, I found that deleting this instruction is the only way to mine other SHA256 coins. Is this the correct thing to do or not?

3) I wondered if their was a similar way to limited the difficulty of work on other SHA coins.

4) On the Windows CGminer version from "cyrpto mining blog" I can't get more then 2 cgminers recognised and everything for the "--usb" command has led to a crashes or command line not recognised.

5) I understand there is no SHA only command for Gridseed, but you simply overclock it higher and high up to 11GH. Is this this correct or not?

Some help from the community would be very much appreciated?
