Should be Input Voltage
Setting uncore ratio to 39 makes things a lot easier ... and does not affect performance that much.
you may want to try Prime95 Custom FFT in place with 448K / 800K to check if input voltage fits.
when you get through 448K but have BSOD 0124 with 800K you can try to increase or decrease cache voltage
run 512K/576K to check cache voltage and 720K for system agent.
i spend a whole afternoon getting my 4770K stable with all Ks @ 4.5 with 1.19 VCore
each selective K should at least pass 30 minutes.
Uncore is at X39
I think I will definetly test Input voltage etc. @x46 with Prime 27.9. Testing Vcore and Input with Prime 27.9 helped with x45 too.
My x45 is quite stable now. Got no more crashes at all.
Maybe it is voltage wall, the only thing is I can play Games/Handbrake/Cinebench/fritzchess all 1,26 vcore for X46 Multi. ONLY X264.....rrrrrrrh
