I followed this guideline to oc my R5 1600, now cannot post.
Stuck at white vga led .

My spec:
R5 1600
Strix b350 ( bios 0809)
Corsair lpx 4x2 gb 3000 c15
Gtx 1060

My simptom:
No post
No display

Already tried clear cmos (remove battery, shorting jumper) still the same
Already change ram position
Tried to reseating the hardware still the same
Tried to boot bios from pendrive still no display

Whereas everything worked correctly b4, after follow that allegedly stable oc profile now cannot post.

Is my mobo bricked ??😭😭

I managed to hit 4ghz before (x40 multiplier) but doesn't stable, so im trying looking around for guides. But that pstate change is very shady, with warning like that.
