oh, okay, so you ran the optimisation algorythm. The thing is - it has been written for a fairly wide variety of hardware and in your particular case, it seems to be not working.
I say, OC or optimise your system manually - if you keep steady and read some info about what you configure, you can achieve a much more better result (especially because the ntune isn't working).
OR wait for a newer version of ntune.
So, if no instability of the system occours when you play games or use some heavy applications, don't worry.
