Need help identifying certain registry entries

I recently came across the following registry tweaks for improving in game performance. Before messing with them, I am curious if anyone can identify the purpose of these registry entries.



Type regedit and change:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Processor
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Intelppm

Change on both the "Start" from 3 to 4. Only side effect is the increase of temperatures by a couple of degrees.

Reboot and your benchmarks should be higher.


Thanks in advance.

I think those registry settings control the processor's power saving states. Setting start value to 4 disables those and consequently disables the cpu's power throttling. Basically, it lets you run the processor at max performance all the time, so game performance may improve. Naturally, this will make the processor consume more power, generate more heat and run fans noisily all the time.

As with any other reg mod, there may be unintended consequences, so proceed with caution. Have a backup of the registry, create a system restore point and if possible image your system.

Thanks Bill2. That makes a lot of sense. I have speedstep disabled in bios and I suspect altering the settings will make no difference. Appreciate the feedback.
