One question @miniZ,
Do you have implemented some anti-hacking solution, as Gminer released "optimized" miner for 150_5?
He (or they) become famous as thieves of other miner code, probably they spend some time reverse engineering competitors miners and stealing ideas.
They released beta now which improves 150_5, and previously they updated kernel months ago.
So be aware.
PS: I like your miner, especially --oc2 option can be handy when power limit needs to go down through summer.
Also I noticed that "templimit" option isn't readed from config file.
