Tried playing with voltage and frequency (for the contest) on my two sticks and minera-cgminer pi.
Everything went to hell. Only this morning do I think I got things back to where they were- 24Gh at 225.
Hard to tell from your description what happened. Maybe you could provide more details?
In my case after installing the Y cable, I made very tiny adjustments to the pot then observed the results before making more changes. It took a long time.
Also, since I have two sticks where one performs better than the other, I had to strike a compromise between the two.
/var/www/minera/minera-bin/cgminerStartupScript: line 4: --suggest-diff: command not found
Any thoughts on this one?
That's weird. The "--suggest-diff" option is definitely spelled right. I'm using 32, like so:
--suggest-diff 32
Can you copy the text from the "Manual Options" setting in Minera and paste them in a reply?
Or even better, can you ssh to the RPi and show us what is actually being passed to the cgminer executable? Something like this would show it to us:
ps auxwww | grep -i [c]gminer
Here's sample output from my RPi:
minera 13743 0.0 0.4 3020 2056 ? Ss Sep30 3:52 /usr/bin/SCREEN -dmS cgminer-gekko /var/www/minera/minera-bin/custom/cgminer-gekko --compac-freq 306 --balance --suggest-diff 32 -c /var/www/minera/conf/miner_conf.json
minera 13744 10.3 3.8 162088 17344 pts/1 Ssl+ Sep30 3407:48 /var/www/minera/minera-bin/custom/cgminer-gekko --compac-freq 306 --balance --suggest-diff 32 -c /var/www/minera/conf/miner_conf.json
Well, yes to this part-
Manual options
You have chosen to add all options manually, I will only add for you the pools list, you have to take care of the rest.
--compac-freq 225 (This works)
Please do not include the command name or the pools (they are automatically added).
When it didn't work, it looked like this-
--compac-freq 225
--suggest-diff 80
I've only successfully putty'd into an s1 or s3 . I can manage to get the drink recipe. After that, I need my hand held. What's the default user and password for a minera pi? and I'll try again but don't hold your breath.
