maRRRco Posted November 11, 2014 Share Posted November 11, 2014 Hello my Gpu (geforce 105m, alias nvidia 9400) works fine but I want to tuning it a bit to change thresholds of G states. Anyway, before to start, I observed that my gpu changes power states also if Agpm kext is removed. How can it be possible ? This happens with mac pro3.1, macbook 5.1 or macbook pro 5.1, so what change these states ? Nvidia drivers or other kext? Then I will explane the reason of this question, but now I'm interesting to understand well. 1 Link to comment https://www.insanelymac.com/forum/topic/302552-my-gpu-power-management-is-fine-without-agpm-kext/ Share on other sites More sharing options...
Allan Posted November 11, 2014 Share Posted November 11, 2014 You can use LegacyAGPM: http://olarila.com/forum/viewtopic.php?f=3&t=629&hilit=legacy+agpm Link to comment https://www.insanelymac.com/forum/topic/302552-my-gpu-power-management-is-fine-without-agpm-kext/#findComment-2084197 Share on other sites More sharing options...
mitch_de Posted November 12, 2014 Share Posted November 12, 2014 Hello my Gpu (geforce 105m, alias nvidia 9400) works fine but I want to tuning it a bit to change thresholds of G states. Anyway, before to start, I observed that my gpu changes power states also if Agpm kext is removed. How can it be possible ? Yep, Same here since 10.9 with my Nvidia GPUs (today GT 440). Depends on card-BIOS, but often (all my lowend, midrange NV gpus) also did some basic powermanagement (GPU and fanspeed changes on gpu load changes) without any OSX software controlled AGPM used (= kext not loaded, not configured for my gpu). AGPM working (if working and good own settings!) may give more powerstates, normaly faster reaction on gpu load changes = more fine tuning. For me, since 2 Years i left AGPM "tuning" and user only the basic powermanagement by the cards-BIOS/GPU itself.

maRRRco Posted November 12, 2014 Author Share Posted November 12, 2014 Ok, so is something related to bios/card. Now, the reason of my question: I said the gpu power management is fine without agpm, it can switch over all g-states, but with the low power state(168-160 Mhz clock-memory) the graphic is very laggy and the card take a bit to change state. So I want to change thresholds in AGPM to get rid of the low power state and I did it, but with every possible modded configurations the card can only switch in 2 states (high performance) and the thresholds seems to have no effect on the gpu management. I changed vendor and id according to my card, and I tried with macbook 5,1 and macbook pro 5,1 So modding agpm doesn't affect the management in the way I want. What could I do ?

Austere.J Posted November 13, 2014 Share Posted November 13, 2014 The same as my GTX460. AGPM kexts are not loaded but still the card can change its states. P.S SMBios = MacPro3,1 Link to comment https://www.insanelymac.com/forum/topic/302552-my-gpu-power-management-is-fine-without-agpm-kext/#findComment-2084663 Share on other sites More sharing options...
maRRRco Posted November 13, 2014 Author Share Posted November 13, 2014 With MacPro 3,1 agpm kext will not be never loaded, try to change it to macbook or macbookpro. In my case the kext is loaded but this reduces the states to 2; if I unplug the ac adapter the states becomes 3. Thresholds don't affect gpu management, I can set them to 999 and the throttling is the same. So, there is a way to fine control this card ? Which other kext can control gpu states ?
