Long awaited ;]

Can any1 share his practical wisdom to what causes the error: watchdog GPU0 hangs in OpenCL call, exit?
And the miner sort of hangs and does not restart properly hangs on 'Polo/Solo version' line. It happens almost with any settings (around 1150~1280 Core clock, 2200~2250 memory clock). Maybe Memory clocks of 2250~2200 are not favorable, thou I got 1-3 stable days with 2250 and -5% or 0% to power limit. Weird.
And the display blinks at this error and the top bar of chrome dissappears and 'minimize, maximize' buttons not responding at all >_<
