How To Adjust Cache Voltage To Boost Cache Bus Frequency

Rampage V Extreme and ASUS X99 series owners looking to boost performance can try tweaking the cache bus frequency, while extreme overclocking users can even exclusively boost the voltage to reach the absolute limits. The cache bus frequency is the internal interconnect that loops together CPU cores, L3 cache, PCI-Express and the memory controller together, so a speed up to this subsystem and everything that needs to talk to each other, gets the message across that much quicker! This can directly be measured in apps that read raw memory bandwidth, like AIDA64, as shown below.

Simply reach into the Rampage BIOS and look here:
