3DMark and Windows 8 RTC: Official Futuremark Response

HWBot, a community site for competitive overclockers that will be familiar to many of our users, posted an announcement yesterday banning all benchmark submissions, including 3DMark, achieved on Windows 8 systems.

Before panicking, it is worth clarifying that the exploit described by HWBot has no practical benefit for hardware manufacturers or PC gamers since it only serves to create a false score that does not reflect actual performance. Furthermore, the steps required to exploit this issue are quite unusual and could not be happened upon by accident.

Simply put, you can and should continue using 3DMark (all compatible versions) with Windows 8.

  • Gamers can use 3DMark to test the performance of their Windows 8 systems without concern.
  • Windows 8 systems that have been overclocked by modifying the CPU multiplier through the BIOS - whether manually or preconfigured by a reseller - are unaffected.
  • 3DMark scores included in hardware reviews in magazines and websites are unaffected.
  • You can continue to use our Hardware Channel to compare CPUs, graphics cards and motherboards in Windows 8 systems.

We are, however, investigating the Windows 8 RTC issue so that we can protect the integrity of our 3DMark Hall of Fame. For the good of our enthusiast OC community we will be looking into technical solutions to detect if the exploit has been used.

For everyone else in all other cases, whether press, industry or gamer, there is no reason to stop using 3DMark on Windows 8 systems. If you still have concerns, or want to ask a question, you can post in our forums.

Ah, good. While I agree with their statement, it is a pity no (overclocked) 3Dmark result made on Windows 8 can be trusted until a fix is available.

Massman fix link :)

Link worked for me!

This might not be true, it appears that AMD systems are not effected by this error. If this is true then AMD results are fine.

While true, the only place AMD CPU's are going to be at the top of 3DMark charts is for iGPU.

It sounds like all results are fine as long as no bclock downclocking was done while in the OS. The problem is going through and picking out the bad submissions from all the good submissions. :nana::nana:

Well in this case just not allow Intel submissions under Windows 8 if it is true that AMD systems are not effected by this.

So guilty until proven innocent then eh? :nana::nana::nana::nana: I've made multiple subs using W8, fortunately I'm able to boot into windows at max clocks and don't have to mess with bclock at all.

Belgium Massman says:

Not guilty, but unverifiable.

Finland FM_Jarnis says:

We already have a pretty good idea how to detect this and are working on it...

Belgium Massman says:

With Intel systems "fixed" coming back from an AMD Windows 8 installation, I suspect this is nothing more than Windows 8 choosing the wrong default timer for Intel based systems during the installation. Switching back should indeed resolve it! :)

Russian Federation Antinomy says:

LOL, not only the problem is the same as it was years before, even the fix is the same (change the timer and/or HAL the OS is using for system time).

GENiEBEN says:

Or you could have a background app/service that will read RTC through port 70 every # seconds to check for consistency.
