Settings for 3.8Ghz
-------------------

Works very well and with good temps. ~45C resting and ~80C peaks at 100%.
4.0Ghz would've been nice but this will work for me very well.

Experiments around 4.0Ghz
-------------------------

Same as 3.8Ghz except

    BCLK Frequency.........................[190]
    CPU Voltage............................[1.35]
    DRAM Frequency.........................[DDR3-1531MHz]
    UCLK Frequency.........................[3063MHz]

Not stable.

    BCLK Frequency.........................[191]
    CPU Voltage............................[1.3]

Runs quite hot with maxes of 95C and is not stable.

    BCLK Frequency.........................[190]
    CPU Voltage............................[1.28125]

Not stable. I don't care and I give up.
