Help with AGPM

7 posts in this topic

Recommended Posts

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>

You can use tool OpenGL Triangles (together with atMonitor 2.7.1 for gpu load % view) to figure out AGPM working / Pstate switching.

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).

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.

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

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.
