I hope someone can point me in the right direction here. i been looking for hours and cant get individual unit freq tuned. And i cant find a good post on it.

i running 31 units on a ubuntu box. i modded 5 units some with resistors and some with just the bridges. i ran each unit individual on my raspi and found the freq they will run at without Hw's. i was using scripta or the pi to do this with.

i did a git pull from "git://github.com/dtbartle/cgminer-gc3355.git"

when i enter
"
sudo ./cgminer --scrypt -o site -u username -p x --gridseed-options=baud=115200,freq=850,chips=5 --gridseed-freq 8D8B16785748=1150,8D9123A95748=950,8D6A187B5355=950,8D6A187B5355=900,8D70218C5355=950,6D95246D5650=950 --hotplug 0
"

it says "./cgminer: --gridseed-freq: unrecognized option"

Does this version not support freq tuning? i believe i read else where it does per miner but im thinking that was a different version and not this one.

This is the version that supports the per-unit frequency mods:

https://github.com/girnyau/cgminer-gc3355.git

Note that it also outputs different values for the API, so Scripta as-is cannot display the hash rate. I ended up moding Scripta to handle the girnyau output.

But now I'm using this version of cgminer that outputs the serial number and frequency for each unit (which is insanely useful):

https://github.com/mox235/cgminer-gc3355.git

The above mox235 version is based on the girnyau fork. I code reviewed the changes and it's identical except for the API JSON output changes.

Here's the matching mox235 version of Scripta to handle the display of the new API output (and fixes a bunch of Scripta bugs):

https://github.com/mox235/scripta

I additionally merged in my mods to the mox235 Scripta variant and can provide them if they're useful. I find it nicer to view the Gridseed unit output in KH/s and the total in MH/s.

thanks that help we out alot i go give it a try right now. 1 last question do you have to state every device speed?
