Powermizer INF Section explained


Recommended Posts

I try to fine-tune my INF/registry for mobile use. I managed to get some pretty portable settings but reinstalled Windows this night.

Weird thing is, I cannot reproduce the same Powermizer behaviour - although using exactly the same driver with the same INF - as on my last Windows install.

I now wonder, which strings all influence Powermizer and what they stand for/do, so I can get the best combination. Can any pro give some useful answers on every string?

These are the respective parts in my current INF:

;Powermizer settings
HKR,, PowerMizerDefault,[tab][/tab][tab][/tab]   %REG_DWORD%,	3
HKR,, PowerMizerEnable,[tab][/tab][tab][/tab]	%REG_DWORD%,	1
HKR,, PowerMizerLevel,[tab][/tab][tab][/tab]	 %REG_DWORD%,	3
HKR,, PowerMizerLevelAC,[tab][/tab][tab][/tab]   %REG_DWORD%,	1
HKR,, PowerSaverHsyncOn,[tab][/tab][tab][/tab]   %REG_DWORD%,	1
HKR,, EnableCoreSlowdown,[tab][/tab][tab][/tab]  %REG_DWORD%,	1
HKR,, EnableMClkSlowdown,[tab][/tab][tab][/tab]  %REG_DWORD%,	1
HKR,, EnableNVClkSlowdown,[tab][/tab][tab][/tab] %REG_DWORD%,	1

;PowerSupply settings
HKR,, AllowMaxPerf,[tab][/tab][tab][/tab][tab][/tab]   %REG_DWORD%,	3
HKR,, PerfLevelSrc,[tab][/tab][tab][/tab][tab][/tab]   %REG_DWORD%,	0x2233
HKR,, RMEnablePowerSupplyCapacity,   %REG_DWORD%,	1
HKR,, RMPowerSupplyCapacity,[tab][/tab]    %REG_DWORD%,	3
HKR,, FastResume,[tab][/tab][tab][/tab][tab][/tab][tab][/tab]%REG_DWORD%,	1

The obvious stuff is PowerMizerEnable where 0 disables, 1 enables PM.

What I'm most interested in is PowerMizerDefault, PowerMizerLevel, PowerMizerLevelAC and PerfLevelSrc, they all seem to have an influcence on the cards frequency management.
