Overclocking
Since the introduction of Z87 back in 2013, there has been a return to BCLK overclocking. This type of functionality ensures flexibility for Overclockers compared to previous generations were the BCLK was locked to 100MHz and only the ratio could be adjusted. As many of you will know, Haswell CPUs get very hot with little voltage increase therefore the flexibility and headroom for overclocking can be limited. For the Z97 launch, we are testing with the Intel Core i7-4770K which from previous, extensive testing, has a maximum overclock of 4.6GHz.
Ranger achieved that milestone of 4.6GHz without any problems so we began lowering the Core Voltage to establish minimum required voltage to deliver such an overclock. The Ranger managed to give us the best result we have yet had – 1.27v. This result is testament to the capabilities of this board and having lowered the Core Voltage the temperatures are much lower when stress is applied, compared to other motherboards which demand 1.3v.
