HWbot ban Window 8.

Windows 8 banned by world’s top benchmarking and overclocking site | ExtremeTech

Woo.......

Unfortunately, though, Windows 8′s RTC isn’t reliable. According to HWBot, Microsoft made some changes to Windows 8′s timekeeping routines to allow for low-cost devices and embedded systems that don’t always have a conventional PC-compatible RTC. HWBot doesn’t give specific details (presumably we’re talking really low-level kernel stuff here), but it proves its point with some damning empirical evidence. Basically, if you change your CPU base clock (BCLK) frequency in software (not at boot time), it has a massive impact on Windows 8′s ability to keep accurate time. By underclocking the BLCK of a Haswell system from 130MHz to 122MHz (-6%), Windows 8 loses 18 seconds over a five minute period (see video above); and the inverse applies to overclocking, too.

This is a problem for benchmarks, because they trust your RTC implicitly — they assume that your system is still keeping accurate time, when in actual fact it isn’t. So, if you run a five-minute benchmark on an underclocked system, the benchmark actually runs for five minutes and eighteen seconds (6% longer). If you boost your multiplier to compensate for the lower BCLK, this means that your computer draws 6% more frames or completes 6% more floating point calculations, resulting in a 6% higher benchmark score. If you underclocked your BCLK by 20%, you would see a 20% gain in the benchmarks, and so on. You can see how this would be a bit of an issue for a benchmarking site like HWBot.

For those lazy to click...

cool thanks for the info! it give me another excuse not to buy windows 8! lol

 

[stan216]

first thing that came to my mind: a time machine of sorts by microsoft. we are 1 step closer to manipulating time

Another slap in the face of MS.

But to be honest, the impact on them is not going to be great since most people out there won't bother about benchmarking their system.

Lol... I dun benchmark so once 8.1 is out I will dump my 7.

 

[ocping]

so the so-called RTC isn't realtime... just like how MRT nowadays not rapid

 

[Mythmaker]

Interesting it only applies software...

 

[hlots123]

will video/music play at slightly faster/slower rate too...?

Hmm? Just sync your time with windows time server. I raised my BClck to 200Mhz but it's still keeping the same time.
