    Default CPU Limited? / Maxed out?

    Below is my setup :

    I Can run @ 200 MHz Blck using 18x multiplier @ 3.6GHz no issues what so ever , prime stable , Intel Burn test stable .
    But Cant touch 4.00 GHz , ie 20 x multiplier @ 4.00 GHz. Tried CPU voltages upto 1.4V I keep running into 124 BSOD when i start prime.
    I have also tried uping my QPI from 1.335 to .1.55V and the result is the same BSOD.

    Do you guys think my CPU is maxed out and doesnt like 4.00 GHz and beyond? My Temps on Load are between 65 - 70 C so looks like I have sufficient cooling.
