Mac Pro 1.1 with regular Kernel Panic

I forgot to mention - I know I should have run the Apple Hardware Test, but I don't seem to find any way to do so. It is not starting by pressing D when booting, and I have lost my original installation DVD.

Thank you. I have no third-party kernel extensions at all. This error log is from a fresh install with only the Media Center app "Plex" installed - nothing else (other than system default).

So it's most likely a RAM-related problem, then? I'll see if I can get some new sticks on monday. I'll report back, in case any other users can relate to the problem.

Thank you so much for your time!

Update: I don't know if it matters, but here is a fresh log. 2 minutes old:

Looks like the same issue. Just a thought: Could it be a bad riser card?

Thanks again. You are awesome. Just one more question: Could it, in any way, be the GPU?

Thanks. I have ordered a set of new memory modules. Hope that they will resolve my problem.

I was thinking of other possible resolutions since I have tested the memory without errors with Memtest, and by using them separately and still getting the Kernel Panic events. I guess they can go bad in groups, or maybe all of them, not just one or two.

My location is Europe (Norway), and we don't have a Genius Bar available - but I would definately visit them if I could.

Thanks for all of your help and time!

Everyone with kernel panics that look like yours, has replaced some RAM modules (or occasionally a riser-card) and lived happily ever after. Some had modules with the Vendor's stickers on them and got replacements free under the lifetime warranty provided by that vendor.

Hello, again! 🙂

So, I replaced my FB-DIMMs to a new set of 8Gb (2x4). I thougt for a couple of days that the problem had been solved, but no. Here we go again. 5 kernel panics in the last two days... Even when the machine is idle, and not doing any work.

I just took a quick look through iStat, and noticed that my CPU temps are a bit higher than I'm used to.

Take a look at the attached picture. Is this within accepted temperatures? This is in Celcius:

CPU 1: 59 degrees C (139.2F), CPU 2: 56 degrees C (132.8F). As I am writing this, I can see that they peak up to 63 degrees C (145F). This is when the machine is idle, and not in use for anything more consuming than Finder as an open application.

Could this actually be my problem?

Here is an example of the most recent Kernel Panic log:

Thank you very much for your time! I really appreciate it, and would like to know if I could do anything more than just saying "Thank you"... 🙂

I have swapped all of the old memory-modules with brand new ones. Not using any of the old sticks. I will try to isolate them into groups again, maybe even swapping which Riser card I am using (one at a time with different sticks).

New Riser-cards is on the way, should be here within the week...

It looks like the KPs is coming in "groups" of some kind. Take a look at this:

Each with 4-7 minutes between them, but after a few it stops, and starts again the next day or so... Annoying.

So... I received the new riser cards today. I also received new memory modules last week. Installed the new risers, the new ram - and I still get Kernel Panics. Sooo sick of seeing that screen.

Any ideas on what to try next? The CPU's?
