OSX freeze after installing official nVidia Fermi drivers

[Nap]

Netkas just wrote about new nvidia drivers in MaxOSXUpd10.6.7foriMacEarly2011.dmg. It's version 256.02.05 with fermi support. I'm going to test it right now.
BTW, there're also IDs for GTX570/580 in it

It works. I disabled Wallsaver. Waiting for KPs now.

Just got KP. No FPS increase in Cinebench. It looks like we should wait for v270 drivers.

GTX460 support?

My GTX460 is stable. The performance is ~75% the from Windows, but the system is stable. I have model and render in Cinema4D 4.30h with no KP or freeze. I used the nVidia update method.

GTX4XX cards are stable if you turn off any power saving fetaures of the VGA to prevent the card to lower the GPU freqances. I turned of all power saving features from Snow Leopard and I used the wallsaver method. The wallsaver software transforms any screensaver in wallpaper and the GPU must do some work to animate 1920x1080 pixels (my LCD) = the freqances are not droping.

Download wallsaver from here.

Alsow if you set manual in Bios the PCIE to 100Mhz, may have the same results and the GPU freqancy will never drop to power-save but I have no time to test the theory

Enabling OpenCL for Fermi GF100 cards for Lion
May 14th 2011 Posted to Lion, Nvidia
Latest Lion update (as well as previous one) disables opencl functionality for gtx480/gtx470.
Looks like it was made intentionally, because you can enable it changing just two bytes in GL driver , one for 32-bit part and one for 64-bit part.
You need to patch this file: /System/Library/Extensions/GeForceGLDriver.bundle/Contents/MacOS/GeForceGLDriver

GTX 470 is GF100 and GTX460 is GF104.

I read all the pages of this thread but I suggest to add the most significative findings on the OP.

I think the most efective solution is to edit the video bios and flash it, although I don't want to do that because with higher clocks the card overheats.

In my case I works fine on windows. Zero freezes or BSODs and I can confirm that my card's clocks changes very often when browsing the web or playing games. On OS X it's another story, I have constant KPs even when changing the PCI Express speed, QPI Link, etc.

Using NullCPUPowerManagement does nothing to my system and I get the same temps with or without it. On idle I get about 29 degrees and 52 on load.

I also think that enabling HDMI audio with a proper DSDT edit should help but I need assistance. For example, my GTS450 is not on PEGP on the DSDT, it's on POP3 section.

That's why I need your help.

Maybe enabling properly HDMI audio + graphics through DSDT without GraphicsEnabler could help. I'm currently using WallSaver to keep the card busy.
