Kernel Panics, 2009 Mac Pro nVidia 750ti

[mugwump]

Have a 2009 Mac Pro, SSD in a PCI Card slot, nVidia 750ti Maxwell card -- and its restarting suddenly with Kernel Panics.

The crash logs seem to say its the nVidia drivers.

Anyone else having sudden restarts?

 

[Fl0r!an]

Sounds like you didn't install or enable the Nvidia WebDrivers...

 

[mugwump]

Okay, so after some emergency efforts things have improved: vacuumed out the machine, removed heatsink and re-applied thermal paste, zapped PRAM which then involved screen sharing to re-enable the nVidia web drivers...
... Not sure what's up but I will keep watch over this. It was infrequent restarts, then it was restarts every minute. nVidia web drivers were installed and running on the 4K dell screen.

 

[ActionableMango]

I sure hope you vacuumed with an anti-static computer vac.

 

[Asgorath]

Please attach the crash logs next time. It's really hard to know what's going wrong from a short description alone.

 

[netkas]

Try to clean pcie plug contacts on card, could be a reason (happened to me few times)

 

[brianbrook]

I had alot of problems like yours with a Gigabyte 750 Ti and moved to a EVGA 960 with no problems so far on a 1,1....does your GPU have Displayport, AFAIK MacVidCard just like to flash GTX cards w/ DP because of compatibility issues..

Another panic. Here is some of the crash log:

[MacVidCards]

iS it an Asus card? They don't really play well with OSX. As noted above, I have found the 750 cards with DP to be much better choices.

 

[mugwump]

It's an evga card going through the DP. Zapping the pram (nvram) seems to help for a few days.

 

[Asgorath]

That's the read error panic, which is a hardware problem. As far as I can tell it means the driver has lost its connection with the GPU and is just reading garbage from the GPU's registers (i.e. 0xFFFFFFFF in your case). Check that the card is seated correctly in the PCIe slot, check that the fans are working, etc.

 

[mugwump]

Okay, so I have cleaned the PCI card connection with diluted rubbing alcohol, vacuumed out the dust from the x16 slot, zapped the pram and have now booted it. Thanks to netkas and Asgorath suggestions for this. Hopefully no more texts from the wife, "the computer restarted again!"

 

[mugwump]

UGH -- new Kernel Panic, but this one seems different. Everything is cool, connections are fine, added dust filters on the front and back of the cMP case to keep dust out...
