ASUS X99 ROG Rampage V Extreme Review

On the subject of making overclocking as easy as possible, the importance of clean and stable power cannot be overstated. So often an overclock will fail just because there is a small variance in the voltages actually being supplied, and just having 80 zillion power phases wont temper that problem.
With the ASUS Rampage V Extreme the power design is their Extreme Engine Digi+ IV, which combines the MOSFETs and MOSFET drivers into a single stage. By reducing the amount of stages in the power phase, and then surrounding it with hardware of the best possible quality, the variance in your chosen voltage and the actual applied voltage is greatly reduced, leading to faster overclocks, both in terms of the results and the time taken to achieve them. Whenever you can lessen the time between you starting to overclock and achieving the best possible result from your hardware, life is good.
It's not only voltage that is important. Obviously when you use any energy it is converted to heat, and that heat has to go somewhere. Heat is such a problem when running at extreme overclock speeds that all the top results are obtained with sub-zero cooling. The Rampage V Extreme takes advantage of the space available on the top of the IO section to add further cooling to the motherboard, allowing you to push yet further.
