No GPU Power Managment

[Mangad]

Thx for the advice. Gone searching for the info....

how do i monitor to know this happening ? i have a gtx 460

 

[kokopellix]

use HWsensors (http://sourceforge.net/projects/hwsensors/) for example

 

[Mangad]

There is FakeSMC with optional HWMonitor & Sensors in Multibeast 6.0.0

Patched AGPM.kext, works nice - cool and quiet.

 

[kokopellix]

so what did i wrong if the agpm.kext works in ML but in MAV didn´t?
if you say everything works for you, although with vlc, office, and others?
any help?

How did you patch your AGPM? I added my deviceID under MacPro5,1 in AGPM.kext which is the smbios I am using, but still PM not working.

You need to edit the thresholds for G-states of your card.

The section of macmodel i'm using (for me it's iMac12,2)
GTX570 - DeviceID1086.

<key>iMac12,2</key>
			<dict>

					 <key>control-id</key>
					 <integer>18</integer>
				 </dict>
				 <key>default-control-id</key>
				 <integer>18</integer>
			</dict>

For GTX570 there are 3 PM states ("Threshold_High/Low" sections). For any other card the number of states may differ.
I dont know how to find out the number of states at the particular card.

This is not new to Mavericks. Unless your graphics card is native to OSX (i.e., 5770, 5870, 650M, 750M, etc.) there is no GPU PM. Use search, many threads describe the necessary AGPM patch. You must implement your own patch and maintain it with every update.

Ι have searched but i haven't seen anything related for gtx 660 for mavericks can you provide me some links or help to edit the kext?Thanks in advance.

Kepler/Mobile is AGPM native, device_ids:
GT 650M - 10DE0FD5 GK107
GT 640M - 10DE0FD8 GK107
GTX 660M - 10DE0FE0 GK107
GTX 675MX - 10DE11A2 GK104
GTX 680MX - 10DE11A3 GK 104

Do not use Fermi AGPM (post above) with Kepler, do not use Kepler AGPM with Fermi.

What i should use 660M?Where to add these values in AGPM kext info.plist?
