As the result of weekend-time research, the HWBOT staff has decided to invalidate all benchmark records established with the Windows8 operating system. Due to severe validity problems with the Windows8 real time clock (“RTC”), benchmarks results achieved with Windows8 cannot be trusted. The main problem lies with the RTC being affected when over- or underclocking under the operating system. The operating system uses the RTC as reference clock, and benchmarks use it to reference (benchmark) time.
 
I am running an underclock of roughly 6.5% on my Haswell system. Windows 8 can not cope with this and slows down time. After 5 minutes, the difference between realtime and Windows time is already 18 seconds ...
