Mac Pro 2009 hangs intermittently

I have a Mac Pro (early 2009) that has lived a very cushy life because I don't use it a lot). On 10.8.5 (Mtn Lion) is started hanging intermittently. So I installed an SSD drive and did a clean OS install of Mtn Lion on it and ran updates. It still hangs intermittently, so the OS installation/disk drives aren't the problem.

Here is the trace, what is the likely issue?

Thanks,

A machine check typically means a hardware problem. Since multiple CPUs are reporting problems that typically means a memory problem. If you go to System Profiler

OS X: About System Information and System Profiler - Apple Support

look under Memory and do all sticks say OK?

You have to periodically check by doing this again since the display only updates when you open profiler.

That helps. Not sure what I should do. I don't have high confidence that Apple can really repair this but I suppose if I dish it to them for $299 and they don't then I won't have to worry too much about it. Maybe I should send this out to a third party? I found some processor cages on EBay but looking at that part I have a hard time believing that replacing it is really going to fix the problem .... unless by "processor tray" Apple Geniuses mean that they are going to replace the processor board, not the processor cage with the fans, etc.

Oct 19, 2015 12:34 PM in response to bithead2

by "processor tray" Apple Geniuses mean that they are going to replace the processor board, not the processor cage with the fans, etc.

In the 2009 through 2012 models the entire bottom of the cabinet is a slide-out shelf, the "processor tray". It include processors, their heatsinks, the memory slots, and all the stuff around them.

I suggest you power your off and remove the tray, and examine it closely with a very bright light before you pay to have it fixed. That may be a very expensive busted wire. Also, be certain that the Northbridge chip heatsink is firmly attached, not sloppy. (It sits between the two processors and its heatsink is attached with springs captured on plastic posts. The posts occasionally break, and weird things start to happen when that chip gets really hot.)

Oct 19, 2015 12:53 PM in response to Grant Bennet-Alder

The heatsink needs to be tight and not "wiggly".

You can check that by powering off, removing the AC power cord, and sliding out the Processor/memory shelf in the bottom of the cabinet. The Northbridge chip sits in the middle of the board, and can be checked for 'wiggly" without any dis-assembly.

If you have a wiggly Northbridge chip as others have experienced, read the thread referenced below (applies to 2009 through 2012 models). The Original Poster thought he just had random crashing, but as he probed, the NorthBridge heatsink and its retaining pins became the focus. Richard Schlettyprovided some good photographs (toward the end) as well.

Grant. You are a wizard. I just touched the heatsink and it moved!

OK I got all the tools together and reworked the heat sink on the Northridge chip and put everything back together. Still hangs though, so now the heat sink doesn't move but the hang is still occurring. What would be the next thing to try? Already tried different memory.

Thanks!

Is it the same kernel panic, machine check, multiple processors? or something else?

I ended up getting Apple to do an out of warranty repair for $299 on the entire processor cage assembly (sans processors). That fixed it. So it wasn't memory it was something on the board itself. I believe you correctly pointed that out.
