Kernal panic ?RAM problem

I'm having problems with continual kernel panics and think it may be a RAM problem.A couple of months ago I removed the ram (2*2 and 2*4) and reseated them. After that I had no problems until now.This is the latest report, any thoughts

Could be anything from a loose or unseated module, a bad module, out of spec third party modules or other Hardware problem.


1. Reinstall the 2 factory RAM modules in the top slots and be sure to push real hard on each module with both thumbs to ensure that they are fully seated.

as per > iMac: How to remove or install memory


2. Run the Extended Apple Hardware Test,

as per > Intel-based Macs: Using Apple Hardware Test


3. If the Hardware test comes up clean, recheck the spec's of the third party 4GB modules and only if they are correct, reinstall them in the bottom slots again (pushing real hard) as described above.


4. Re-run the Extended Apple Hardware Test.
