AGPM for Kepler GTX 670 or similar

[nothingmore]

Does somebody here use AGPM for regulating your GPU clocks?

My GTX 670 works only half-well, since, well, ever.

I've got an older EX58 board (Nethalem) and a gtx670 gpu (Kepler), and i've got OpenGL problems that i can't resolve.
Everything works out of the box, including graphics and Cuda, but openGL is kinda slow.


The GPU goes down to about 300MHz in windows when idle, on the mac it stays at 731MHz when idle.

Some Benchmarks and games can clock up the GPU to 1.1GHz, and other things like Cinebench or certain games can't.

Cinebench and other OpenGL benchmarks give me a third of what i've read others on osx86 can have with it.


I'm weeks into this problem and nothing works so far...



It should be possible to regulate the P states with AGPM:

Only i never got this to work, not in 10.8, 10.9, 10.10, and now in 10.11

Anybody got an idea what to do?

I've tried LegacyAGPM edited for my smbios, but loading it via Clover results in a back screen and a restart of the machine.

DSDT CPU C & P states work, but i have no SSDT for graphics.

Have you ever tried installing the Nvidia web driver?

Yes, apart from 5-10% more fps in benchmarks, nothing happens.

The card idles at step 2 I think, which is 731MHz. In Windows it idles at Step 1, ~300 MHz.

When I edit the AGPM info.plist with my model and deviceid, it will reboot instead of showingthe desktop.
Verbose mode shown no errors though.
