Associate decided to cancel all of the gains achieved by the Intel platform, combined with the operating system Windows 8. Moderators of the central overclock portal found out that the results of the popular benchmarks affect the system real-time clock (RTC, real time clock).
For example, if you set the base frequency to 130 MHz and the multiplier - to 32, and then modify these values from operating system, respectively, at 122 MHz, and 34x, CPU frequency will not change and will be equal to 4160 MHz. However, after the manipulations described Windows 8 win 18 seconds at a five-minute segment, which is reflected in the results of the benchmarks. The difference can be up to 7%, which is unacceptable for competitive overclocking.
