Need Help Enabling HPET (High Precision Event Timer) In Vista
A lot of forums do not allow you to link to other software this is why he did it. Vista General Sidewinder Precision 2 install problem w/VistaI got a new computer with Vista.

A high value (in the 1GHz to 4GHz range) implicates the Time Stamp Counter (TSC) of the CPU as being the source.

Then I turned it on and noticed a huge performance increase in the Windows Aero animations.Click to expand... Why don't you just try it for yourself? Loading... There is nothing else concerning this that I can 'adjust'.
If just one more player can get the same boost as me I'm happy. @Mister D, yes, it seems to be rare in modern motherboards/BIOS to have HPET options. New Posts What are you sick of? I can't comment on how things are in Windows world, as I only been interested in Linux developments in this area, but from countless intricate problems Linux guys had with HPET Hpet Bios Gigabyte Reminds me of a teacher i had in elementry when you'd ask her what a word meant she would tell you to look in the dictionary.
I was just chatting with a guy who tweaked it up to 14 MHz and he's testing it right now to see if it's better. @JediPanther, that sucks. itsakjt said: ↑ Just go to Device manager and expand the "System Devices" section. and how does it effect the OS ? That's what made me think leaving it on in the BIOS was harmless..

I've heard this too but I think this is an old issue. Those that don't will *usually* have it enabled all the time. For me: There's no appreciable difference with it running or not. Coincidentally I have two desktops, one a C2Q and next to it a 4670k and HPET is on in both of their BIOS' and OS'. Hpet Reit

Ironically the very high count rates obtained in TSC mechanisms (as compared with PMTIMER or the Intel HPET device) can cause a problem that the measurable time intervals are too short: There is a lot more EM noise on my microphone socket on my Auzentech Prelude soundcard (used for listening to satellite TV through PC as I'm not using a pre-amp or have a peek here But doesn't that ring a bell already?
You can only set it in bios. Hpet Vs Tsc I've been trying different tweaks, still can't get a solid 60fps... Edited by octopec, 02 January 2016 - 08:32 AM.

But worry not, there are several timer event sources available in modern systems: HPET, LAPIC timer (basically a timer in cpu package) and good old PIT straight from 1990. It is thus not surprising that PMTIMER and Intel HPET systems use a clearly specified fixed rate that is deliberately targeted at producing resolutions in the sub-microsecond range, allowing them to Plus I'm unsure if the Asus P7P55D Pro has a HPET toggle, will have to check later. Check This Out Confusingly, such Windows XP systems quote "HPET" connectivity in the device driver manager even though the Intel HPET device is not being used.
I used to think that those options had to do with the "bitness" of the installed OS, but I no longer believe that to be true.
