    We added aditional ram to iMac late 2009, it start ok and is working much faster but everyday we get a kernel panic message and need to restart, sometimes 1 time, other 2-3 times. How to solve that?

      If you still have your original Apple ram that the computer shipped with I would remove all of the Kingston and replace it with the original to see if the panics stop. Most kernel panics are caused by a ram fault and Kingston is one of the brands that are known for causing problems, especially if it’s their value ram. Don’t bother with Ram testing utilities like AHT or Rember, they’re ok but not 100% accurate.

      There are a couple third party system kexts showing up in your latest panic report, a Safe Boot would turn all non Apple stuff off and if the panics stop you should suspect some third party software, if the panics continue you can suspect hardware, and I would suspect the ram first. http://support.apple.com/kb/HT1564

      It’s usually an issue with the ram. Re-install the original ram if you still have it to see if the panics stop. Most kernel panics are caused by a ram fault. Don’t bother with Ram testing utilities like AHT or Rember, they’re ok but not 100% accurate.

      Did you use the same RAM that was already in there? Mismatching brands of RAM can cause instability.
