es3000 Posted June 9, 2016 Share Posted June 9, 2016 Hello! I have motherboard ASUS M5A97 LE R2.0. Operating system - Windows 7 x64. When I turn on parameter HPET in BIOS, the time in Windows begins to lag behind real. In 1 minute there is a lag for 20 seconds. And begins a glitches when playing some games. Is It malfunction of the motherboard? Link to comment https://www.neowin.net/forum/topic/1299986-slow-down-time-in-windows-7-when-turning-on-hpet-in-bios/ Share on other sites More sharing options...
+BudMan MVC Posted June 9, 2016 MVC Share Posted June 9, 2016 did you do bcdedit /set useplatformclock true after setting it in your bios?

oldtimefighter Posted June 9, 2016 Share Posted June 9, 2016 Easy solution for this one... Turn if back off bud. My understanding is newer motherboards with Windows 7 and higher SHOULD NOT be using HPET. Anyone with a better understanding of this please chime in.

+BudMan MVC Posted June 9, 2016 MVC Share Posted June 9, 2016 where did you read that? I would say its complete opposite, older OSes do not support it while new current ones do.. Windows 7 has support for it, but you have to tell it to use it from my understanding. XP before sp3 did not support it, Link to comment https://www.neowin.net/forum/topic/1299986-slow-down-time-in-windows-7-when-turning-on-hpet-in-bios/#findComment-597448470 Share on other sites More sharing options...

My question to the OP is if you are doing a lot gaming why are you even using Windows 7?

SIE Posted June 9, 2016 Share Posted June 9, 2016 High Precision Event Timer has been around for years and should work with 7 no problem, have you made sure the driver is installed in device manager?

es3000 Posted June 9, 2016 Author Share Posted June 9, 2016 To use or not to use HPET - is other question. But anyway the system must to work correctly. Even if there will be no advantage from HPET. Violation of time shouldn't be. Right? It means that motherboard is not good?

Because I have more got used to Windows 7 Well you seem to be concerned about performance and Windows 10 is faster. Windows 7 is a dead end with no DirectX 12 support for gaming. I am sure you can get "used" to Windows 10.

spaceelf Posted June 10, 2016 Share Posted June 10, 2016 My advice with HPET is to leave it alone. Newer OSes will use it, older chipsets can be buggy with it, but let the OS deal with it...it's really not worth it.

es3000 Posted June 13, 2016 Author Share Posted June 13, 2016 Guys, the motherboard was faulty. I have replaced motherboard to another, and time in system goes correctly with a new board.
