Editing AGPM to prevent GTX4XX Freeze

[starchild]

Agreed. Somehow I managed to fix it partly, not really sure how as I thought it didn't work. Now I do see AGPM in the console. My freezes are less frequent, and certainly not anything to really care about, considering Lion is around the corner.

I nearly broke my entire system doing this, so can't afford to screw it up again!

I've edited AGPM.kext but I used the code meant for MacPro4,1 and instead marked it as iMac12,1 because it will kernel panic at boot with MacPro in SMBIOS. At first I could see AGPM loading and changing states in Console, now it doesn't show up when I search for it, there was another person out there who said this happened, I don't know what the problem is.
My real concern is the use of UseNvidiaRom=Yes in the Boot.plist. I have edited my original EVGA GTS 450 bios rom to have only one power state and corresponding voltage setting. In System Profiler it shows up as;
Vendor: NVIDIA (0x10de)
Device ID: 0x0dc4
Revision ID: 0x00a1
ROM Revision: /Extra/10de_0dc4.rom
Note: I have not flashed my bios, only loaded my edit at boot with UseNvidiaRom.

Will it now use the edited bios rom? I have the feeling this is an old solution for older 7-200 series Nvidia cards and not actually meant for what I'm trying to do. If it does use this rom then there shouldn't be any P state changes.

Update: Still getting kernel panic. I would be interested in knowing what this boot.plist Nvidia command is actually doing.

yeah..after few days, the KP is back. I broke down and ordered a 5770 instead.

You and me both. Everything runs so god damn smooth. Just put my GTX on sale on kijiji.

Sorry - long time no posts Was in the hospital for a bit and have busy with work since.

First - this isn't a perfect fix, obviously. It, to me at least, seems to mitigate crashes based on power management/throttling, but it seems like there's a host of things wrong with the driver. I've gotten a couple of OpenGL crashes that have brought down the system, for instance.

Second - the issue we're having with these cards are only temporary. Lion's updated Fermi drivers don't cause the same type of kernel panics we're seeing now in 10.6 - trust me on this

Just wait a bit longer and the majority of issues we've seen with this card and drivers will be gone.

hi Scorcho,
hope all is well. I am definitely looking forward to Lion.

is this the same chameleon in MultiBeast 3.7.2?

 

[eelhead]

Mutlibeast 3.7.2 has Chameleon 2.0 RC5 r877 in it already, what's linked above is an older version Chameleon 2.RCr851.

so far I found R1000 here (http://www.kexts.com/view/1348-chameleo ... r1000.html)

with the change logs (http://forge.voodooprojects.org/p/chameleon/timeline/)

looking through the change logs right now..might give it a try though...

[EDIT]
install R1000 and also updated to the latest CUDA. Current uptime is 3 hours..will update.
The only changelog that might impact us is the HDMI audio fix for NVIDIA. Wonder if that's causing the crashes.

[EDIT again]

yup..crashed...yay!
