Overclocking Notes

Hardware

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.
