    It looks like you're only loading three cores with P95 judging by your temps. Also, a few mins of P95 is not enough to verify stability. Different people will tell you different lengths of time to run it. Some say 8 hours is stable, some say 12 hours, some say 24 hours. Personally, I run it until it has made one full pass on each core, regardless of the amount of time it takes(this may not be feasible for some, as with some of my systems this has taken 36+ hours.)

    That aside, I do have some tips to aid in your quest for stability(which I'm sure some may disagree with, those of you who do, speak up. I'm simply an amateur compared to a lot of you folks here on XS.)
    Lower your 2nd VTT voltage, that does nothing to help with overclocking and can cause odd instabilities if raised too high. Just make sure it's within .3v of VTT and you're ok, so you should be able to set 2nd VTT to auto or whatever stock is and be fine.
    Also raise your CPU current capability to 180% and frequency to 450.
    Since you're running 8 sticks of RAM, up your VCCSA to around 1.225v. Also a slight bump in your PLL voltage to around 1.82v may help.
    Your VCore may also be a little low, but that's on a chip-by-chip basis. You might want to just raise it by a good notch(1.42ish) for stability testing and go back and lower it later and retest for stability.
