Bug In Over Clocked Windows 8 PCs

Windows 8 is the latest version of the Microsoft Windows operating system. Microsoft hopes that the Windows 8 OS will help them to improve the sales of tablet computers and notebooks. There are not much Windows 8 problems reported in the Microsoft support forums. This article deals with an overclocking bug that is reported in the Windows 8 operating system.

A bug has been reported in the Windows 8 OS. This bug is related to the real-time clock and is said to cause inaccurate benchmarks in over and under clocked computers. Clock frequency is a factor that determines the performance of the CPU. When the clock frequency of the computer is adjusted from within the OS, the software timekeeper no longer keeps track of the time and reports the time inaccurately. This will result in slowing down with an underclock and speeding up with an overclock.

The HWBOT team found that after a 6% CPU base clock decrease, the time in the computer after five minutes lagged behind the actual time by 18 seconds. In case of benchmarks, this translated to a 5 to 7 percent score boost, when compared to a computer of equal clock speed that is modified only through multiplier adjustments. Likewise, a base clock increase caused the score to decrease in the same benchmarks.

After finding out this problem with Windows 8, HWBOT is no longer accepting the benchmark results in the operating system. They are planning to invalidate all the previous Windows 8 results. The problem with this bug is that there is potential for the overclockers to use this bug for their advantage. The HWBOT wants to make sure that there is no scope for cheating.

The real-time clock is a hardware feature of almost all the computers. Its duty is to keep track of the current time. In certain low cost and embedded systems, the RTC circuit is removed. This is done to save costs and in the Windows 8 OS, Microsoft has made many changes to preserve the time-keeping compatibility in these machines. Now that it has been found that these changes affect the benchmark in some situations, Microsoft will look for solutions to patch this issue at the earliest.

Let us hope that Microsoft will come up with a fix for the overclocking bug soon. If you would like to know more on the overclocking bug and other Windows 8 problems, you can refer to the Microsoft support forums.
