Seems like two of the miners do not quite like 1000Mhz but it seems to work otherwise, do only --gridseed-options=baud=115200,freq=1000,chips=5 (or however fast you want or how many chips you want working) and --scrypt .


EDIT: 850Mhz worked much better, will experiment more.

running at 900mhz on cgminer for a few hours now.. really stable

getting about 385 kh/s

You can't monitor and/or use remote monitor for your farm using cpuminer. Huge limitation if you have a decent size farm.

cool, how big is your farm?
mine is only 5 GS5s right now...tiny farm

Don't think you can correctly read the hashrate on the pool side... my poolside is always higher and fluctuates.. i think cgminer does a pretty good job in reading actual hashrate vs shares accepted

There are ways to monitor hashrates for bulk devices.

If you have a large farm it would be a good idea to install some custom scripts and cacti or a custom web front end to monitor and manage everything from one place.

Leaserig stats are great to see GPU vs GridSeed:

I can only get 2 to run on windows 8.1. (in CGminer)

Anyone having more success with this? Help is appreciated.

This driver is for people trying to install the gridseed under windows 8.1 it is a link to the ST comm drivers. This is for Win 8.1 64 bit

Check this page post 76 i believe. Explains how to set the COM ports to USB in the miner scrypt.

This will work for CGminer? I have gotten it to work for the cpuminer just not cgminer.

I dont see the cp2102 to uart bridge controller only stcomm32

Hmm, that doesn't make sense, where averaging is concerned.

Oh cgminer I cant even get cgminer to work. If you could help me there I would appreciate it. I have the ST32 also and not the CP2102. My miner never finds the gridseed.

I can get it to find 2. At one point i had it find 10 aka one full hub and start hashing. I had 20 connected tho. Since then no luck.

With 2 all i have to do is unplug them and replug then restart cgminer. I have gotten 3 running by starting 2 instances of cgminer. but now when i do that it just says devices in use.

Try cpuminer, much easier to work with....MUCH!

Good luck!

On Raspberry Pi: you gotta add --scrypt at the end

Code:

git clone  https://github.com/dtbartle/cgminer-gc3355.git

cd cgminer-gc3355

./configure CFLAGS="-O3" --enable-scrypt --enable-gridseed

make

./cgminer --gridseed-options=baud=115200,freq=900,chips=5,modules=1,usefifo=0,btc=16 --hotplug=0 -o stratum+tcp://usa-1.liteguardian.com:3335 -u user -p x --scrypt

finally got 10 gridseeds working on cgminer.!!!!

On windows? How?

[vabchgent]

How did you get Cgminer to work in windows I am still trying to figure it out? Thanks in advance

Also zoomhash.com now has the gridseed miners at 234.99 a piece right now if anyone needs any in the US. I have dealt with them and can vouch for them.
