OK, so finally after a solid week of learning, programming and pulling my hair out, I have some basic understanding of mining. Let me tell you my hardware setup then I'll get to my problems. I am running a Raspberry Pi B+ with Raspberian operation system and I'm using 3 dual mode Gridseed miners running off cgminer 3.7.2I have figured out how to get them to mine in scrypt mode but I can't change the frequency of the units individually, I can only change all of them at the same time. My next problem is that I have tried mining on 2 Bitcoin sites (Slush's pool being one of them) and I can't get my miners to work with Slush's pool at all, so I used another site and managed to get my Gridseeds to mine BUT, again I can't change the individual frequency and they only mine in scrypt mode, also all shares are rejected. I have followed the instructions/tutorials and they should be working in GH/s in BTC mode but I'm getting KH/s. I have also noticed that while searching the internet for the command codes, they seem to vary slightly, this makes it awfully difficult to track down the correct code that works.
This is the scrypt code that works for me when I mine scrypt currency;
sudo ./cgminer --scrypt -o stratum+tcp://(server address):port -u (my username) -p (my password) --gridseed-options freq=850
This code gets the miners running but not correctly;
sudo ./cgminer -o stratum+tcp://(server address):port -u (my username) -p (my password)
I have tried many variations but this code starts and runs the miners for scrypt. So basically if anyone can help me and tell me why I'm getting KH/s when trying to mine bitcoin and what the correct code is to mine SHA-256 currency and also how to change the frequency of each unit, I would be most grateful. Like I said earlier, I'm new but I learn pretty quickly but just can't figure this one out.
Many thanks
