CPU Ratio
Using the same grading of the Haswell, the Z97 CPUs fall into the K-SKU and non-K SKU
grades. The K-SKU are equipped with the maximum multiplier up to 80x; while the non-K
SKU will be restricted by the Intel Turbo Ratio Limit. Therefore, if you want OC, choose the
K-SKU CPUs.
The Intel 9-Series Chipset is Intel’s main product for 2014. Strictly speaking, the structure of
the chips is a slightly modified version of the 8-Series chips with the support for PCI-e M.2
interface added. In terms of overclocking, they are identical to the 8-Series chips in their
structure as well as limitations. Therefore, the Z97 chip is the main chip for overclocking.
Coupled with the K-Series processors, it comes with a complete set of overclocking
options, such as CPU Ratio, BCLK and Memory Ratio. As the H97 is not capable of being
overclocked, the Z97 platform is thus the preferred platform for overclockers.
Please note that although the Z97 is an all-new product, Intel has yet to release any new
processors in the lineup concurrently. So, for now, gamers still have to rely on the Haswell
CPUs for overclocking, such as the currently available 4770K and 4670K. The new CPU
Codename is designated as Haswell Refresh and it is predicted to be a slightly modified
version of Haswell.
