Overclockers know that overclocking generation Sandy Bridge and Ivy Bridge by increasing the frequency of the base generator (BCLK) is severely limited because of the close connection of cores and third cache level, PCI Express controller and other components.
ChinaDIY get samples of processors E3-1280 v3 and Core i7-4770K. Colleagues note that in the settings menu of the motherboard are available Dividers BCLK value 1.25 and 1.66, similar to enthusiasts on LGA 2011 platform. After a simple manipulation of the system parameters , Core i7-4770K successfully loaded at a frequency of BCLK 170.1 MHz Multiplier 25x (frequency 4.25 GHz). CPU-Z utility incorrectly identified the processor, attributing to him the letter T instead of K.
But with the processor E3-1280 v3, also have design concept LGA 1150 similar trick with changing the BCLK frequency fails, access to the right setting was simply closed.
