A few days ago I upgraded my mac book pro to 16GB of RAM and now I am getting some kernel panics with page faults. Are page fault kernel panics typically caused by bad RAM or could there be another cause? I did run the Apple hardware tests after I installed the RAM and it did not find anything wrong with the RAM.

  • Typically, page faults are not caused by bad RAM (though it’s not 100% out of the question), but by software corruption of kernel data structures. – microtherion Mar 13 '14 at 21:00

I would guess, assuming that the RAM was the only thing you changed (you didn't upgrade the OS or the HDD), and that the kernel panics didn't happen before the upgrade, that yes, the RAM is the culprit. It could be perfectly fine working RAM for a PC, but Macs are picky about their RAM, which can lead to problems including kernel panics.

Since your drivers don't include any special one, it's possible from the RAM. If the RAM doesn't reliable, sometimes it will corruption of kernel data then cause these type of issue as well. I had some experience with no stable RAM rather than fault RAM.
