Hostname | OpenWrt
Model | Raspberry Pi Model B Plus Rev 1.2
Firmware Version | OpenWrt Designated Driver r49390 / LuCI Branch (git-16.132.13167-ba1ef5b)
Kernel Version | 4.4.7
Note that /usr/bin/cgminer-monitor in crontab is disabled for testing purposes.
Either via gui or via ssh running: cgminer --avalon4-fan 40-100 --avalon4-freq 200 -o stratum+tcp://solo.ckpool.org:3333 -O <address>:<pass> -o stratum+tcp://stratum.mining.eligius.st:3334 -O <address>:<pass> -o stratum+tcp://stratum.f2pool.com:3333 -O <address>:<pass> --api-allow W:127.0.0.1 --api-listen ... and / or ... cgminer --avalon4-fan 40-100 --avalon4-freq-max 200. In both cases the machine will start out around 2.0 TH/s. Within about one hour, however, the machine will slow increase in frequency until it is running at 3.0-3.5 TH/s. Even setting it at freq=100 or freq-max=100 incurs the same behavior.
Update: The solution may be adding the parameters PoolBalance:Load-Balance and --rotate 5. This is stable for at least a few hours now.
System notes:
