A Russian player recently found that his Ruilong 9 7950X suddenly showed running on the ultra-high frequency of 6.3GHz!

Of course, this is impossible, because he is not overclocking, and the normal frequency of the Ruilong 9 7950X is only 5.7GHz.

Although the player did not disclose the motherboard model and BIOS version used, he can confirmThis comes from a 10-year-old RTC Bug.

This comes from a 10-year-old RTC Bug.

The reason is that the ldquo; real-time clock & rdquo; (Real-Time Clock/RTC) used by Windows 8 leads to differences in the identification of processor buses between operating systems and test software. the processor frequency and running scores can not be fully trusted, and it is easy to cheat (15% difference), especially when overclocking and frequency reduction, Intel processors suffer.

After reducing the bus frequency, the RTC timer frequency also changed.

Microsoft later claimed to have fixed the Bug, but in the AMD Zen2 era, it was found that it was still there, and now that it is Zen 4, Microsoft has not completely solved it.

It's also easy to reproduce it.Just let the Ruilong processor run at the highest frequency, then let the system hibernate, and then restore, the frequency will be magically increased, Windows task manager and CineBenc, Corona and other test software will be deceived.

Of course, this Bug will not have any impact on the operation of the system, but will be good-looking and can be regarded as an alternative.
