I think Im pretty stable on AIR @ 4.2GHz
I ran :
Prime95v25.11 for 30min test no errors
IntelBurnTest v2.4 passed at 1024 mem and also at very high stress 4096mb
CPU-z is showing core voltage 1.312v idle and, 1.312v-1.296v Load
Temps at idle : 33 C
Temps at Load : 65 - 70 C
Most likely going to run Prime 95 for a few hours now and see what happens...
These are my current bios settings:

I was having a Hard time reach 4.2Ghz ..
these were my steps to get 4.2GHz (200x 21) no LLC yet:
@1.343 Vcore,1.335vQPI/VTT -bsod 0X00000124
@1.343 Vcore,1.355vQPI/VTT -bsod 0x0000001E after 18min prime
@same as above but with Load-Line Calibration (Level 1) bsod 0x000000D1
@same as above but I added QPI PLL = 1.2 ******STABLE it seems*******
Im not too sure but I read this Thread saying that sometimes any Overclock above 190BCLK he needed at Least 1.2 QPI PLL.
Anyways please share your ideas and comments of what I can adjust? or not to touch anything
