The 7750 is a Black Edition CPU and as with all models which feature this branding it is unlocked. This allows us to change both the bus speed and CPU multiplier when overclocking and gives us much more flexibility in our attempts to find the maximum stable speed.
To overclock the 7750BE we configured the M3A78-T bios for manual overclocking and set the CPU voltage to 1.4v, 0.15v above stock. From the original speed of 2.7GHz via a 13.5x multiplier and 200MHz bus we found the highest overclock to be 3570MHz.
