kjp4756 Posted September 23, 2012 Share Posted September 23, 2012 Ok I am on 10.8.2 and using the nvidia drivers that come with 10.8.2. I have a gtx 560ti and I'm trying to wrap my head around the thresholds in AGPM kext. Here is what I have for threshold values. Can somebody tell me why my card never enters state 2? I don't want state 3 to be used at all. Right now it sits in state 1 most of the time and it will switch to 0 when it needs to. <key>Threshold_High</key> <array> <integer>55</integer> <integer>45</integer> <integer>75</integer> <integer>100</integer> </array> <key>Threshold_Low</key> <array> <integer>0</integer> <integer>85</integer> <integer>99</integer> <integer>100</integer> </array> Link to comment Share on other sites More sharing options...
Rampage Dev Posted September 24, 2012 Share Posted September 24, 2012 Read my mountain lion AGPM guide here: http://rampagedev.wordpress.com/2012/07/08/editing-applegraphicspowermanagement-kext-for-nvidia-graphic-cards-2/ Link to comment Share on other sites More sharing options...
mitch_de Posted September 25, 2012 Share Posted September 25, 2012 You can use tool OpenGL Triangles (together with atMonitor 2.7.1 for gpu load % view) to figure out AGPM working / Pstate switching. http://www.insanelym...engl-triangles/ If you put more gpu load % (a few % up to full load (>= 90%))) by highering the triangles count (from 20 up to a few thousand) you can check AGPM switches (console output by setting Logcontrol=1 in AGPM kext).

kjp4756 Posted September 25, 2012 Author Share Posted September 25, 2012 Thanks. I got it working now. It switches between states 0,1 and 2 like it should now. It looks like my card (according to cpu-z in windows) only has 3 power states. 50mhz, 405mhz and 822mhz. Those clock speeds correspond with states 2,1 and 0. State 3 is useless in my case. I'm hoping that by locking out state 3 that it fixes the random channel timeout errors I've been getting (so far no issues in 2 days). If that doesn't work then I'll keep it in state 1 and see what happens. Link to comment Share on other sites More sharing options...
stefano.85 Posted September 28, 2012 Share Posted September 28, 2012 Hi guys, i have similar problem with a geforce 9400m (ATOM n330+ ION). my GFX has 4 states according to CPUZ. In snow leopard 10.6.8 with a modded legacyAGPM.kext when in idle it stays in state2 but in ML (with vanilla agpm.kext modded) it always switch from 1 and 0 states only. I've read Rampage Dev article related to AGPM and i think i don't understand at all the difference between 10.6-7 and 10.8 power management. I've tried both atmonitor+opengl triangles bench, and even if the gpu percentage is low (8-10%) the state is always 1. Where am i wrong? tnx for troubleshooting cheers Link to comment Share on other sites More sharing options...
mitch_de Posted September 30, 2012 Share Posted September 30, 2012 Maybe, because of your AGPM parameters even running only 8% gpu load (using OpenGL triangles at lowest count + atMonitor to show gpu load) are some wrong. Try to run only atMonitor and check back gpu % load (shoud be 1%) and the G-State in console. You must wait some time (1-2 sec ) for changes shown in console. Only if there is also no G-State 2 (or 3) = lower gpu State something is wrong with your AGPM settings. I found out that switching up to faster G-Step (G-State down) goes fast / at less gpu loads. But switsching down needs really less gpu loads. 2>1 is for me if less than around 21% gpu load. Link to comment Share on other sites More sharing options...
stefano.85 Posted October 1, 2012 Share Posted October 1, 2012 ok, i'll try that. i'll make some screenshots to show you in case of problem. tnx mitch Link to comment Share on other sites More sharing options...
