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.

Here is the impact of our overclock on the Fritz performance:
Last month Intel launched their Z97 chipset, essentially an evolution of Z87, which in many cases brought new features such as SATA Express and M.2 compatibility to the mainstream desktop market. There was of course no new CPU at that time with the existing socket 1150 processors working without issue in the new boards. Since then though Intel launched (along with some lower spec models) the Core i7-4790K, a model which sits at the top of their mainstream platform. Today we see how it compares to various other models when installed on Gigabytes Z97X Gaming 5 and paired with PowerColors new dual core 290X Devil 13.
