I'd like to find the optimal power saving settings on my GTX 560 Ti. I'd like to hear some other peoples feedback and testing on their optimal settings in AppleGraphicsPowerManagment

Once I got my card recognized in Lion, it still didn't perform well. It was being throttled to a maximum power saving state.

I started by opening /S/L/E/AppleGraphicsPowerManagement.kext/Contents/Info.plist
Then located my Mac identifier which was MacPro4,1... It's burried inside IOKitPersonalities > AGPM > MacPro4,1
I copied one of the entries labeled Vendor10deDevice05e2, and pasted it as a child of MacPro4,1 (or in other words a sibling of Vendor10deDevice05e2) Ive also found that the iMac12,1 has a good scheme that will work.

If you add the SensorOption 1, then your video card's power saving function will work, it will switched from all the different modes. If you leave it out, then you will be running in power state zero, which is least amount of power savings, but better performance for scrolling/launchpad.

Then we renamed the entry to match my graphics card device id "Vendor10deDevice1200" <-GTX 560Ti

update:

(I've found you can replace VendorXXXXDeviceXXXX with GFX0 or GFX3 or whatever your motherboard enumerates your primary video card as) GFX0 is the default for iMacs, but it won't work on my motherboard because it's enumerated as GFX3.

Settings

I've enabled log control so it will print to the log each time my graphics card changes it's power state. I also have a kilowatt power meter which also shows me that it's actually working.

From another forum, as suggested, I increased the IdleInterval to 500, so it doesn't switch unnecessarily and frequently. Edit: I've switched back to 100 to continue further study.

I removed the sensorsamplerate entry, and it's been fine without it so far.

Then we have to adjust the Threshold_High and Threshold_Lows.

I don't want to go into explaining all this on this post so I'll include a couple links where it's all been talked about before. Those numbers basically tell the operating system when to switch power saving states. Those numbers represent what I believe to be GPU % IDLE. So 100 meaning the GPU is completely idle and not being used. 0 = GPU has no idling and is working 100%.

http://www.insanelym...p...t&p=1667641
http://www.tonymacx8...hp?f=15&t=20367

My settings are not finalized yet, but they are working. I'm still testing and I'd like to get some feedback about what others are doing / testing.

Side note, It seems that in windows 7 and xp, the video driver takes it's cue to switch into higher gear from directx or the software. This is my theory of course, I would like to find out.

Thanks

How to enable log control?

edit：I know how to enable it now

[thiago.net]

IT also have a GTX 560ti But I'm not getting optimal performance. Its post your files?

You can get optimal performance, but for me to help you get it right, I'll need you to do a few things.

1. get your GFX number, GFX0 or GFX2 GFX3 etc

Do this in terminal (that's a lowercase L):

ioreg -l|grep attached-gpu

Should say something like:

"attached-gpu-control-path" = "IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/PEG3@3/IOPCI2PCIBridge/GFX3@0/NVDA,Display-A@0/NVDA/AGPM"

That is mine, what I'm looking for is the GFX number, mine is GFX3 for my primary video card and display.

2. Your model identifier as found in /Extra/smbios.plist under <key>SMproductname</key>
example: MacPro4,1 iMac12,1

3. Then make a backup of /S/L/E/AppleGraphicsPowerManagement.kext
We'll refer to this as AGPM from hereon

4. Open AGPM by right click and show package contents. Go inside Contents folder,  and edit Info.plist with PlistEdit pro.

5. Locate IOKitPersonalities and expand > Expand AGPM > Locate your Mac model identifier here as found in step 2.

6. Empty the contents of this entry

7. Locate iMac12,1, expand, copy GFX0 and LogControl inside your (2) Mac model identifier entry so now it should be basically a duplicate of iMac12,1 but under your own mac id.

8. Go back to your mac id entry which should now have GFX0 and LogControl inside it, and rename GFX0 to whatever we found it was in step 1. GFX?

9. Expand GFX? > Expand Heuristics > Right click IdleInterval > New Sibling

10. Name it SensorOption, Class Number, Value 1

11. Change LogControl to 1 if you wish

12. Save

13. Run kext utility for Lion

14. Reboot

Here's what mine looks like as a reference.

Info.plist for AGPM

Here I've setup the MacPro4,1 model to work with the GTX 560 Ti as GFX3 and mac model identifier MacPro4,1.

[saltdos]

Just as a quick verification (and for those who do this in the future):

Quote

X:~ x$ ioreg -l|grep attached-gpu
    | |   |   | |   "attached-gpu-control-path" = "IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/P0P1@1/IOPCI2PCIBridge/GFX@0/NVDA,Display-A@0/NVDA/AGPM"

There's no number displayed, so I would assume its GFX0? Or just GFX?
Lastly, where is the LogControl file found?

[thiago.net]

Camoguy, I used the command "ioreg -l|grep attached-gpu", but I do not return anything! I used your Info.plist in my AGPM and changed my SMBIOS to MacPro4,1, but my Lauchpad continued to lag.
Use in iMac10, 1, remove AGPM, but to have a great performance have to put at rest and wake up!
I do not know what to do...

[scorcho]

for nvidia cards using iMac12,1 or 12,2 you don't need to include the PEG or GFX string (on my hack it's showing as PEG, not GFX). simply include Vendor10deDevice#### key and it'll recognize your card.

also, here are my Threshold_High and Threshold_Low settings that i've settled on for my card. Cinebench scores have increased by 12 FPS using these settings, and the interface is buttery smooth. i've set the lowest p-state to 999, which effectively disables it, hence the performance increase both in 3D games and in Finder. since these cards relatively cool, you shouldn't have an issues with heat.

scorcho, I made this change you indicated and changed my SMBIOS to MacPro4,1.
But for me to have maximum performance, no lag in Lauchpad, I have to add a widget with the effect of water!
I ran the command with SMBIOS MacPro4,1

Mac-Pro-de-Thiago:~ Thiago$ ioreg -l|grep attached-gpu
	| |   |   | |   "attached-gpu-control-path" = "IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/pci-bridge@3/IOPCI2PCIBridge/display@0/NVDA,Display-A@0/NVDA/AGPM"

In your case I would go with GFX. That's an oddball, very interesting.

Just curious, have you by chance tried updating your DSDT from tonymac's database? http://www.tonymacx8...dsdt.php<br />
Also, I'm not suggesting you change your mac model identifier to mine, I just want to show you mine as an example. I think there is a language barrier. English is my second language also.

You see what that widget does is like the old fermi freeze problem was about. It keeps the video card busy so it doesn't invoke power saving state 3. Once it goes to that third state, it reduces it's clock frequency down to 50 i believe which isn't enough power to keep things smooth.

I'm experimenting with the possibilities of using GFX0 or such to replace the Vendorid. Vendorid seems to work, but this also worked for me, so I'm asking others to try it and give me some feedback.

Take a screenshot of that setup in Plistedit, which install method you use? iboot xpc efi multibeast, vanilla

Smbios looks fine, GF100Hal is okay, I don't use that many arguments with my gtx 560ti to get booted. All I have is graphicsenabler=y

You have, the blank graphics mode fix, -v npci=0x2000, pciroot 1, and use kernel cache. I haven't ever seen that last one. Whats that for? If you would remove those "fixes" from chameleon, what happens to your system?

I've made a few mods to the applegpm info.plist. Here you go.

Once you modify a kernel extension file remember to:

sudo chown -R 0:0 /System/Library/Extensions
sudo chmod -R 755 /System/Library/Extensions
sudo kextcache -v 1 -a i386 -a x86_64 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions

Good luck

Get nothing from ioreg but: Denniss-iMac:~ dennis$ ioreg -l|grep attached-gpu

Great thread, i really thought everything was working ok, seems the graphic card is not doing its work though.
My system identifier is: iMac12,2. I tried to put in "Vendor10deDevice1200" with the strings you have attached as a screenshot in iMac12,2. rebuilded caches etc. and rebooted. Think it's working now! 4951 frames in GL view 4.0, openGL 2.0... is that ok? The fans does'nt spin up at all, they do that when im running windows, guess i might overheat at some point?


The now shows nothing at all, when i type: ioreg -l|grep attached-gpu, not even the: ioreg -l|grep attached-gpu
    | |   |   | |   "attached-gpu-control-path" = "IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/P$



If i look in my console it says:

and:

9/19/11 2:18:01.932 AM PluginProcess: AVF error: AGPMGetManagedPortForAccelerator returned 0x4 for VP4


What does it mean?

Quicktime is still stuttering a bit when i go from window mode to full screen, anyone else who have the same problem?

Thank you again for a great thread!

Fascinating, okay first off, in your signature, add your system spec details etc, so we have an understanding of what kind of platform youre on.

It seems to me like you're not seeing the entire output of ioreg, try increasing the window size. Other than that, you could try ioregistryexplorer. Navigate around there till you find the entry for your pci2pcibridge that your video adapter is plugged into. Might provide some insight.

Those screenshots in the first post are kinda old, since then I've adjusted for more optimized settings. Try these for threshold values in heuristics. Should eliminate some of the stuttering transitions, it will keep the video card in power state 2 for the most part. Which is still reasonably good power savings, about a 15 watt difference on my machine.

High
0: 25
1: 40
2: 60
3: 100
Low
0: 0
1: 75
2: 90
3: 98

You'll want to enable logcontrol for debugging, to see if you're actually switching to different power saving states on the video adapter.

Double check your plist, see if you have control id 17, SensorOption 1, Targetcount 5. Perhaps attach your plist zipped up to the forums so I can take a look or screenshot.

What score you get from running the opengl test in cinebench? http://www.maxon.net.../cinebench.html
That might get the fan spinning...

Thanks for the acknowledgment!

Hi again

Got my g-state working:


9/19/11 8:41:49.000 AM kernel: AGPM: GPU = display G-state set to 0 from 3, ControlID = 17
9/19/11 8:41:55.000 AM kernel: AGPM: GPU = display G-state set to 1 from 0, ControlID = 17
9/19/11 8:42:00.000 AM kernel: AGPM: GPU = display G-state set to 2 from 1, ControlID = 17
9/19/11 8:42:05.000 AM kernel: AGPM: GPU = display G-state set to 3 from 2, ControlID = 17

The stuttering while playing quicktime videos in full screen fixed (kinda), i'm running dual screen so it's like dragging the background on the second screen under the video which cause the stuttering. It's ok when i just run on a single screen.

The fans are still not running at 100%, i will try to find a 3d game or something.

Still cant find my device ID, tried to look at ioregistry but im not able to find it there (dont know where to look).
Do i need to install: Nvidia plugin and Nvidia fermi OpenCL enabler from multibeast Lion edition?

cinebench openGL: 37,92 FPS

All looks good to to me, but I would possibly remove some of the boot.plist settings like arch=x86_64 pmVersion=23 and UseKernelCache. As far as I know, my system doesn't need those two settings, and it still achieves the same result. Unless you know you need it then I wouldn't bother. Always backup before you do though.Those cinebench results are great, that's above average id say.
