An HPET chip Consists of a 64-bit up-counter (main counter) counting at a frequency of at least 10 MHz, and a set of (at least 3, up to 256) comparators. These comparators are 32 - or 64-bit wide. The HPET is programmed via a memory mapped I / O window that is discoverable via ACPI. The HPET circuit in modern PCs is integrated into the southbridge chip.
Theoretically this tip gives a boost in the whole machine.
First of all make a backup of the settings bcdedit.
Open CMD as board administrator -> Windows key + x, click Command Prompt (Admin), type: bcdedit / export C: \ BACKUP_bcdedit hit enter. A file was saved with the name given in C: \.
If you do only using the restore point or re-installing windows (experience).
To restore just do the same procedure with the command: bcdedit / import C: \ BACKUP_bcdedit.2.3.2.
What we will do is change the QueryPerfomanceFrequency windows.
Retrieves the frequency of the high-resolution performance counter, if one exists. The frequency can not change while the system is running.
28v = VS.85% 29.aspx)
As I understand it, would be a function that returns the time it takes for the CPU to calculate an operation. More or less. The smaller the better.
This tip can be used to improve performance in games, even resolves some lockups in games.
Programs to measure it:
TimerTimming nvidia: https://developer.nvidia.com/content/timer-function-performance
WinTimerTester 1.1: http://www.mediafire.com/?xzo9n84d8lze9nb
WinTimerTester Download the file, run it as Administrator and make sure the QueryPerfomanceFrequency is as below:
If not with this number:
To begin to change, Open CMD as board administrator -> Windows key + x, click Command Prompt (Admin), type: bcdedit / set useplatformclock true, hit enter and reboot.
Upon reboot, go into your BIOS and activate HPET function on ASRock this function is called ACPI HPET Table:
After system initialization, download the file and check that the WinTimerTester QueryPerfomanceFrequency now with a number 14.xxxxx Mhz, as in the first picture.
