Kernel Panic (with 16GB Ram)

[MBX]

Hi

i get kernel panics after a few min's of running the Mac pro. The ram are perfectly paired (2x 4gb in both slots, both in the first 2) and i get issues with it it seems.

it started to happen as of today but didn't happen the days before. Nothing was changed in the configs or software.

What's going on?

Any ideas?

You go to "About this Mac" and see if you have an RAM errors yet?

Try downloading iStat and see how hut they are running?

Where did you get the RAM - are they properly heat-sinked?

Out of curiosity did you follow the RAM-Riser install pattern Apple recommends? It shouldn't matter all that much; most likely it's a bad stick there are RAM test software on the install disk, and others on the internet.

I ran it up it showed the full 16GB

then the kernel panic happened and i had to shut it down.

next time i started up only 8GB showed up.

the ram don't seem faulty. i took out each of them and tested it. they all work. but somehow they don't want to work together anylonger.
