Need Help Enabling HPET (High Precision Event Timer) In Vista
bcdedit /set useplatformclock true (then reboot) enable HPET bcdedit /deletevalue useplatformclock (then reboot) disable HPET Ok so I enabled it, rebooted First things I notice are it took twice as long I posted it because he asked if Windows has some way to do it. This feature is not available right now. A lot of forums do not allow you to link to other software this is why he did it. Source
Uploaded for nvidia support - Duration: 9:25. Asus sabertooth 55i doesn't feature that option... Plus I'm unsure if the Asus P7P55D Pro has a HPET toggle, will have to check later. Am having problems installing some older software, with the joystick being one of them. visit

A high precision event timer. Without timer generating interrupt after 1ms it can't reliably wakeup. Without timer generating interrupt after 1ms it can't reliably wakeup. All trademarks mentioned are the property of their respective owners.

Read that quite a few motherboard manufacturers have Opted out of supporting the feature, so not everyone has it.

I checked every inch of the bios for HPET but it's definitely not there. https://en.wikipedia.org/wiki/High_Precision_Event_Timer So it boils down to the following distinction between clock source and clock event devices.
Your ratio is excellent so it might indicate that there is no sync - meaning you might have LAPICs. Hpet Asus Bios The Witcher 2 has just as much eye candy, and a single 670 runs it Maxed... I'm playin in the 1st mission on the ship, and whenever I face a window and look far off the fps drops to 20fps (with a 670 sli setup LOL)... But the ratio took longer to stabilise at 1.000 (took 180 seconds), it was alternating between 0.9997 and 0.9999 a lot.
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. look at this web-site My i7 3820 for example is running at 4.5Ghz on air and memory is at 2400Mhz (4 channels of it,) as well as two SSDs in RAID-0 and 3 HDDs in Hpet Windows 10 It's possible that the chipset relies on it being on, so turning it off isn't an option.

You need to force HPET only and reboot. Hpet Vs Tsc Edited by Yosharian, 02 January 2016 - 08:41 AM. I can't really think of a good reason to disable it unless your systemboards implementation is crap (it happens).
Enable HPET in BIOS.
Exactly. This has the express advantage of being independent of the CPU frequency and still provides a very reasonable sub-microsecond resolution and accuracy. I'm glad that I finally have a platform that I'm happy with though.Click to expand... Wintimertester bcdedit /deletevalue useplatformclock (then reboot) is said to remove it.
Modern systems have HPET and make great use of it, stuff like high precision wakeups needed in modern media players to drive precise audio/video timings and still sleeping when processing is Mar 5, 2013 at 12:51 AM #23 jonathan1107 Joined: Dec 30, 2010 Messages: 1,216 (0.53/day) Thanks Received: 55 Location: Canada System Specs System Name: Brutus Processor: i5 4690k @4.7Ghz (Watercooled) Motherboard: As far as memory and CPU speed is concerned, the i7 875 @ 4Ghz isn't bad, but you have new architecture chips pumping out higher numbers without water. Check This Out HPET seems to be disabled by default in Windows 10, but there is a way of manually enabling it.
If you have the HPET option in your BIOS, I highly recommend experimenting with it and see if it impacts your performance. But doesn't that ring a bell already? If you want to see whether it's turned on in the Operating system, use this command in the command prompt with admin privileges: bcdedit /deletevalue useplatformclock If you get an error Is there no way to turn it off IN windows 7 instead of the BIOS ?Click to expand...
