Hpet Windows 10
If you've looked everywhere it's possible that you might not be able to disable it.

The other timers will give you significantly less frequency. This anomaly muddies the water about what is meant by "HPET" on such systems, but it is clearly not the 15MHz Intel device in those cases. Also note that if your ratio is not 1.0000 you are off set (or you have wrongly OC'ed), enable HPET and you should be without sync problems. The number of applications that can choke after you do this is surprising, especially games. * After a few minutes it seems to have settled at 1.0000. useful reference

Heh. Vista was heavily pushed into using HPET. There's a possibility that having it on could increase the amount of microstuttering in any given game; particularly if you're running SLi.

But doesn't that ring a bell already? Now this doesn't work on Vista or Windows Server 2008 (not R2 which is derived from Windows 7) and shows an error message saying "data type specified is not recognized". Please check out our forum guidelines for info related to our community. Hpet Bios Gigabyte Results: All results were identical (within 1%) except X3:TC which dropped from 141fps to 131fps (7% drop).
Been running it for about an hour now, and while my top end isn't any different, I am noticing a much smoother FPS average. I dont doubt that some people will find it helps in an extreme circumstance, but not for me. Some hardware has both. Others on OC.net say it's missing on their gigabyte z87 as well.
But this device has no driver and is not used at all. ^ With a Linux kernel, you need the newer RTC-CMOS hardware clock device driver rather than the original RTC Hpet Asus Bios the DPC latency goes through the roof and limits the FPS in the games. However apart from the DPC latency readings I certainly can't tell the difference in benchmarks or games between HPET ON/OFF in the bios. EDIT: Something for Windows 8 users: bcdedit /set disabledynamictick yes What it will do is stop Windows from coalescing CPU clock ticks when idle, a feature added in Windows 8 for
Yes, I have HPET enabled No, I do not have HPET enabled I do not have an option for HPET in my BIOS Multiple votes are allowed. https://forums.anandtech.com/threads/do-you-have-hpet-enabled-or-disabled.2362109/ It could be that the processor is no longer allowed to sleep (to conserve power), and you are seeing the effects of Intel's CPU power-management (or rather the lack thereof) on Hpet Windows 10 This is on a Windows 7 machine with an Intel i7 975 processor and chipset. Hpet 32 Or 64 When I enable it in windows and get 14.3 or so mhz in wintimertester my system feels completely different.
If Windows 7, Windows 8/8.1 isn't using it as a default, then it's highly unlikely that the next version of Windows will. http://vehizero.com/need-help/need-help-with-new-build-that-cannot-use-windows-10-with-gpu.html Share this post Link to post Share on other sites Salty Wagyu 44 moo 44 1,561 posts Location: ConDem Nation Posted May 8, 2012 Is this on TSC+LAPICs?

Invariant TSC is great for keeping track of time, but it's not an event timer source, capable of firing off events (interrupts) at certain times. First off, my DPC latency dropped big time. When I tested this value before enabling in Win10 (just enabled in BIOS), I had a very poor value. (EDIT: In Wintersdark's post below there's a great tool for checking if http://vehizero.com/need-help/how-to-use-windows-10.html and/or their respective licensors.
So you're saying HPET is separate from Invariant TSC in terms of functionality, but everything I've managed to find seems to say that Invariant TSC is a replacement for HPET. Hpet Vs Tsc Funny as I don't have any problems like that.

Intel is just leaps and bounds ahead right now.
A high value (in the 1GHz to 4GHz range) implicates the Time Stamp Counter (TSC) of the CPU as being the source. Source HPET is programmable timer with plenty of functions. I would setup MSI Afterburning to output Framerate, both GPU temps, and both GPU usages to the OSD and I would see how load changes according to frame rate. Wintimertester bcdedit /deletevalue useplatformclock (then reboot) is said to remove it.

I suspect for most they won't see a change at all. http://vehizero.com/need-help/need-help-with-windows-8-1.html Here's an interesting description of TSC and HPET: Since Windows 7, the operating system runs tests on the underlying hardware to see which hardware is best used for timekeeping.
Thinking about it makes me really sad. I don't expect this to work, by try setting your power options in Windows to "Performance". Set it to 64-Bit in BIOS and enabled it in Windows with the Command shown earlier. A lot of forums do not allow you to link to other software this is why he did it.
Never thought about it with this rig because it was built ground up for 3D rendering, but I will have a peek. Then I stumbled upon a setting in BIOS (motherboard is a Gigabyte P67A-D3-B3) called HPET (High Precision Event Timer). https://www.google.com/search?q=Sab...75,d.dmQ&fp=a81f7da92f51477&biw=2560&bih=1294 From what I've read, there's no reason to turn it off.Click to expand...

What kinds of differences were you seeing Carfax? #6 BSim500, Jan 4, 2014 SPBHM Diamond Member Joined: Sep 12, 2012 Messages: 4,211 Likes Received: 67 Carfax83 said: ↑ What OS So that's how timer event source differs from timer source. Even if it only helps a few it helps.Certainly not limited to Win10. Like I mentioned earlier, the technology is nearly 10 years old at this point.
So you're saying it might be worth it to disable the Core's HPET?
