I also had 3 x'es within the O's just after a reconfiguration + restart.
Restarted again with fingers crossed, only one x remaining, and I set the clock to low.
Re-restarted still with fingers crossed, all x'es went away, all O's.
Set the clock back to high, waited for 30 mins, still all O's. Phew!
I wonder if these issues are heat related. Anyone experienced it, added cooling and didn't happen again?
I do not think cooling is concerned. Otherwise I do not understand much criticism for cooling. My blade is cooled with a single ASUS fan of 12 cm forward. The fan blows cold air on the right side of the blade. The blade is in the vertical position (standing on their part with the cooler). BLADE is overclocked cool as a cucumber. I can not believe that such a stable made.I think even my overclocked BLADE can operate without a fan.
I'll hit mine with a Infrared thermometer tomorrow, and I can get you some rough numbers to compare against. I can test with no cooling, 1x200mm, 1x200mm+1x120mm, and 1x200mm+2x120mm.
