Hi! I have a Dell Studio 1555 with mobility 4570. I have followed the posts and now I can get QE/CI and full resolution BUT the problem is the fan that doesn't switch off. How I can manage energy and power saving feature of this GPU?

Is your CPU working with NATIVE speedstep?? That was my problem, my cpu was working always at 100% and the temperatures were too high. When I patched correctly my DSDT and I was able to use AppleCPUPowerManagement my temps become lowers.

 

You can try to use smbios from a imac 10,1 (if you have a C2D cpu) or 11,1 (if you have a I series CPU)

Yes it is working with Native speedstep cause I was abled to patch my DSDT. Maybe The problem is that there isn't the powersave feature for Ati Cards on Snow leopard ^_^ How can my laptop be useful if the battery run down in no time?

 

leo, chiedo scusa per l'off-topic, potresti dirmi come hai fatto ad attivare QE/CI con quella scheda su quel pc?

che versione di osx hai montato ? e che kext hai usato per la scheda videooo? sono disperato!!

 

Allora devi usare Snow 10.6.6. Poi scaricati il file in allegato e sostituisci il file "boot" sulla tua partizione Mac con il boot peregrine. Mi raccomando rinomina il boot peregrine come "boot". Poi installa Atiframebuffer.kext e Ati4500controller.kext

Ah dimenticavo! Devi usare l'ultima versione di Chamelion

Grazie Leo, ascolta ma tu hai usato la hazard 10.6.2 e poi hai aggiornato?

 

Scaricati la hazard 10.6.6. a me per qualche strano motivo la 10.6.2. non mi fa partire l'installer

I used the kexts from here, as I have the exact same graphics card as you, however I get a blank screen with only the backlight on - how can I fix this?

 

Many thanks :D

Ati and Nvidia powerclock throttling settings is controlled inside /System/Library/Extensions/AppleGraphicsPowerManagement.kext. ( Info.plist inside that )

 

PP = POWERPLAY, this is the option to have energy saving enabled in a ATI card:

 

"PP_GFXClockGatingEnabled" means that the cards clock can run with different speeds, adjusting to load. 1 or true will activate this, 0 or false turns it off

 

"CFG_NO_PP" = TRUE is Energysaver OFF. FALSE is Energysaving ON.

 

 

for me (Shrike FB) this is working from ATIFramebuffer.kext, all Energysettigns activated :

 

<key>Shrike_Personality</key>

<dict>

<key>CFBundleIdentifier</key>

<string>com.apple.kext.ATIFramebuffer</string>

<key>IOClass</key>

<string>ATIFramebuffer</string>

<key>IOMatchCategory</key>

<string>IOFramebuffer</string>

<key>IONameMatch</key>

<string>ATY,Shrike</string>

<key>IOProbeScore</key>

<integer>65000</integer>

<key>IOProviderClass</key>

<string>IOPlatformDevice</string>

<key>aty_config</key>

<dict>

<string>PP_GFXClockGatingEnabled</string>

<key>value</key>

<integer>1</integer>

</array>

</dict>

 

 

this is my Powerstates ( imac10,1 for my Toshiba C2Duo Laptop with 4650 mobility from AppleGraphicsPowerManagement.kext

In real world usage this has the effect that the Laptop boots with the fan blowing, after around 40 seconds in OSX it goes silent , entering a low powerstate and stays that way, until I launch 3D apps ( games , imovie or extensive watching videos) then it is blowing at full speed - later medium, but will again go silent when that app/video/game has been quit. For the most time ( surfing, office ) the card is in that low power mode and only minimal sound of the fan is heard.

 

I use no Disablers or Nullcpu*.kexts and run the vanilla apple kernel in x64 mode - osx 10.6.7 - the Laptop is very stable, I can have it all day long on without a problem , also no overheating problem in the last days.

 

On battery I tested only shortly for around one hour , no fail. ( battery in Windows lasts only 1.45 hrs )

i'm not sure what was actually done here?

 

i'm running the kexts that leo90 posted in his studio 1555 thread, they work very well for qe/ci, however the fan is running constantly due to high power usage. i'm using native power management for the cpu, but just from reading your post i don't know what (if anything) is supposed to be changed in the graphics kexts to enable the power gating.

 

leo90, can you let us know what you changed, what worked? i tried changing smbios.plist to iMac10,1 but the situation is the same as before.
