My luck with the GTX 560 so far (freezes from time to time)

[GreenDude]

Hi there!

So I've used a Gigabyte GTX 560 (non Ti) for 1-2 months now and the only critical issue I have yet to solve is the random freezes I get from time to time.

What I've done so far:

1) 10.7.2 + UniBeast + Multibeast 4.2.1 (standard stuff + GF100 Fermi Patches)

btw, the Fermi patches *do* have effect, right? All the GF114 & GF110 results I find on google are confusing.

2) Added my Device ID (0x1201) to NVDAGF100Hal.kext

at this point I had full resolution

3) LuxMark threw an error so I modified libclh.dylib to allow OpenCL 2.0 like it says here viewtopic.php?t=43705&p=290908 and it compiles!

4) Adjusted AppleGraphicsPowerManagement.kext as follows: https://gist.github.com/7e1d95e7bc9f52dcf231

I've seen various Threshold setups in several posts but I can't really tell if I nailed the right one or if this is what's causing the freeze.

boot.plist: https://gist.github.com/8d0e2da91966060f8df2
smbios.plist: https://gist.github.com/2f037ea8b3684ed1b03e

(added the blank Graphics Mode later on but didn't feel any different)

Mkay!

Currently I get 29-30 fps in CineBench, is it good or bad for this card?

All in all I would be happy with the above but every once in a while the system freezes. I think I hear the card's cooler or something else go louder, I can still move the mouse but in the end I have to restart.

If I open up kernel.log I only see these G-state switches:

Jan 30 01:41:53 Stefans-Mac-Pro kernel[0]: AGPM: GPU = display G-state set to 1 from 2, ControlID = 17
Jan 30 01:41:59 Stefans-Mac-Pro kernel[0]: AGPM: GPU = display G-state set to 2 from 1, ControlID = 17

And sometimes I see: (don't know what it means)

Jan 30 01:50:31 Stefans-Mac-Pro kernel[0]: IOSurface: buffer allocation size is zero

When it crashes however I get these line repeated over and over:

Jan 30 03:24:44 Stefans-Mac-Pro kernel[0]: NVDA(OpenGL): Channel exception! exception type = 0x1f = Fifo: MMU Error
Jan 30 03:24:44 Stefans-Mac-Pro kernel[0]: 00000069

Does anyone else have any insight on how the freeze might be fixed? Would really like to turn this into a guide

Cheers!

oh, and I found this topic to be the most useful viewtopic.php?f=15&t=35148

Switched to MacPro 4,1, I'll see how it goes

So I got a freeze today after all, I also updated the kexts via viewtopic.php?f=15&t=48009&p=302148#p302148

Interestingly, they console messages vary a bit now:

Did you find a solution, I have the same problem?

Hey there,

I just had the same problem After hours of gaming and browsing it suddenly crashed. First there was the beach ball and then it froze.

Thanks in advice!

Today I got another freeze This is really annoying.

I've got the exact same problem in 10.8

here's my post

I found that I had to set my system (with a 670, not a 560 so YMMV) to MacPro 3,1 or I'd get all sorts of wierd lockups, 4,1 and 5,1 would often not boot and the MacBook Pro settings would give the wierd lockups, generally as soon as any "intensive" GPU stuff started happening (playing a video etc).

Obviously the system gets pretty reliant on hardware being "as it expects" despite my system specs being much closer to a late-model MacBook Pro than an old-model MacPro.

A good test I found is to play a video from YouTube (2/3 of them will do it, the other 1/3 will work just fine, depends on codec I assume) - if you get video corruption, then wait another few seconds and the system will likely lock solid other than the mouse pointer, which after about a minute will beachball.

Friend

I am using the same card GTX 560 (Non TI) mine is asus. It is running smoothy on Lion now i upgraded to Mountain Lion. In ML i get native support i.e from the installation screen No freeze yet. Please update ur OS with compo update downloaded from apple site to 10.7.3 0r 10.7.4 and use latest multi beast, and use open CL enabler and then download latest cuda driver from Nvidia site and install it thats it you get full resolution and open CL Open GL CUDA all work perfect. Think this help you

I get the same messages in console.

Safari open, Mac idling for some time and as soon as i get back I often get these messages in console and weird graphic glitches in Safari. Sometimes the computer freezes, sometimes it doesn't.
