I can usually fumble my way through linux, vi, and an ssh interface.
I assume you meant cgminer.conf. The value 415 is not available in the web interface drop down. Changing the 410 to 415 in cgminer.conf results in the listed frequencies in the Miner Status page to show 415. Going to the Advanced Settings page where you would normally change the frequencies using the drop down, the drop down box is blank.
For this test, I had to reboot the miner via the web interface. How do you restart cgminer through the ssh?
Yeah,I meant cgminer.conf, doh.
This will restart it through the command line: "/etc/init.d/cgminer.sh restart"
I expect the web interface, after changing to 415, will be blank (don't worry, if you select any other frequency and apply, it'll be back to the way it was) since the web interface is reading the frequency and doesn't have a match in the html for "415".. so it just shows blank.
Ok, so if the miner status page showed 415, that suggests this one is *NOT* factory locked on frequencies.
It's just a matter of figuring out how far it can be pushed... Thank you!
