ram upgrade

Reinstalling your old, known-good RAM would certainly be a test of the your RAM upgrade; if the kernel panics stop, it'd be time to get the supplier of your RAM upgrade to make good on any warranty they offer. You could also open System Information in the Utilities folder and check Memory in the Hardware category to see if the status is "OK."

Most obvious is you have bad or incompatable RAM.

Reputable supplier of Mac RAM is your best bet.

Most suppliers have a lifetime warranty on RAM sales.

OWC

Crucial

both are good source.

Re-install your factory RAM if you want to get back up and running, until your new/replaced RAM is returned.

After installing the RAM, status is OK? Which RAM? Corsier's or Apple's?

A kernel panic can disrupt the orderly writing of files, etc. to disk, which is not a good thing.

Removing one of the 8GB DIMM's would be one way of testing them. If one causes kernel panics and the other doesn't, you'll know that one is bad as well as which one that is.

You can do the following:

Run an Apple Hardware Test and see if it picks up any RAM problems.

You can download Rember from Kelly computing and run a a test overnight:

This is superior to the AHT.

Yop could post a copy of the kernel panic for inspection:
