MP 1,1-5,1 Mojave random kernel panic on Mac Pro 4.1 -> 5.1

[Aidzer0]

Hello all, I have a 4.1 > 5.1 mac pro (2009), it has the 144.0.0.0 firmware on it, 4x 8TB HDD's, AMD 7950 GPU, 2x X5680 CPU's and 8x 8gb RAM (64GB). Mojave is running off of a 500GB Samsung SATA drive.

I have had this Mac Pro for 5 years now with absolutely no issues, up until a year ago one of my CPU's died (No boot unless the faulty CPU was taken out), I replaced both the CPU's with X5680 chips, the CPU that died came with the mac and I don't know what it experienced.

I have had no issues at all with the Mac up until 2 weeks ago, I have been experiencing Kernel panics on a daily basis, I have run AHT with no faults/alerts besides the videocontroller alert (which I read was normal for 4.1 -> 5.1 upgraded machines). I have just about done every test that I have read about on here and various other sites and nothing is giving me any hope for fixing this.

Something worrisome I have found is that one CPU heat sink is a lot hotter than the other (The one closest to the back runs hotter), maybe because its getting heat from the front one?

The main role for this machine is a Plex server. The Kernel Panics happen during plex transcoding.

The kernel panics are of the reboot flavour, they all point me to power delivery of some sort, but I dont have the Mac knowledge to pursue this further, any help is welcome, the panic is traced back to the AppleIntelCPUPowerManagement.kext, the affected Processors are all over the board, each panic event seems to have a different processor number.

I am currently trying to get ASD 3S130 to run, but its not going past the Loading screen of both OS and EFI, I am now downloading a different version (3S132).

I have done a lot more than I have listed, but I am flat lining at the moment after 3 weeks of troubleshooting...

Thank you!

I attached the .panic files but that got removed, here they are in plain text.

It is a common problem that the thermal paste dries up and/or the plastic clips disintegrate on the Northbridge chip especially on dual socket Mac Pros causing random kernel panics and freezes. You’ll need to remove the Northbridge heatsink, repaste it, and then the hard part is that you’ll need to find replacement clips. There are some plastic ones on Amazon you can buy or you can get creative with bolts and washers or zip ties.

PM me and I’ll send you some clips in the mail.

 

[Aidzer0]

Good suggestion, I’ll try that as soon as the ASD finishes downloading.

Last night I repasted the CPU’s and reseated the ram, I looked at the NB heatsink, there doesn’t seem to be a way to get to the underside of the board to safely remove those clips without either breaking them or removing the board from the tray, correct?

Thanks!

You need to remove the board from the tray to get to the northbridge heatsink, which means you need to take the CPU heatsinks off again. There are screws around the outside edge of the board that you remove to take the board off the tray. I don't recommend breaking the clips off but you probably will anyway when you try to remove them since they are quite fragile.

Gotcha, thank you! I will report back once that is completed. Hopefully that will be the solution!

@Aidzer0 :
There's a very simple way to check if the rivets are broken or not.
If you installed some fan control app e.g. MacsFanControl or iStats menus , you can see all Temps.
If the difference between NB diode and NB heatsink is more than ~ 12 Celsius, a NB repaste and replacement of the rivets (if old) is necessary.

Seems like we have a repaste in order..

I attached the .panic files but that got removed, here they are in plain text.

NMI KPs are a classic symptom of northbridge overheating.

First check the push-pins and before repasting the northbridge check if the die is not concave or convex, very common when it overheats, also do the same for the heatsink.

Concave/vex die?? I really hope that didn't happen... Thanks for the info, will be checking all of this soon, I'll leave the Mac off for now.

I just ordered new push pins along with more thermal paste. So I will need to wait for that before checking this.

Thank you!

 

[tsialex]

Concave/vex die?? I really hope that didn't happen...

The die and the heatsink itself will distort when overheated for a long time, specially when just one of the push-pin pair is broken.

A distorted heatsink can usually be lapped and it's an easy fix, while a distorted northbridge die will make the CPU tray useless since it's not cost effective to replace it and every time you heavily use the CPU the kernel panics happen.

CPU trays with delta bigger than 12ºC after correct maintenance is done are usually northbridge die distorted.

 

[Aidzer0]

Okay, after hearing the die could be warped... I made a plan, I found an old MB that has those clips, I changed out the thermal paste (which was rock hard). Now these are the results:

Its not 12C. But it is really close to 12C difference...

Also, it seems as though I did not mount one of the CPU's correctly so one bank of RAM slots is not showing... The whole no cage on the socket is really heart wrenching...

Thanks again for all of the help!

10 to 12ºC are the expected delta for anyone in a hot climate. If it's over 12ºC, then you have stop and investigate what's wrong.

Gotcha, thank you very much!

After you do the northbridge maintenance, check if you have a healthy NVRAM volume. The KPs are saved inside the NVRAM stores and make a real mess that overtime can become a corrupt volume/brick.

Thank you @tsialex as always! Your knowledge overwhelms me! I have fixed my problem just reflashing BootROM using the reconstructed one that you made it for me. Now everything is ok again

Fixed the issue with RAM, just reseated CPU B, absolutely traumatising having to torque that heat sink down...

You do that every 3 months? Wow. Okay, time to mark some dates in my cal too.
Thanks for the heads up. I will be doing that asap.

Regarding opencore, since I have a AMD 7950 (planning to get a RX 580 when prices are normalized), should I use opencore now? Or just wait until I get a 580?
(I did have Martins opencore installed, but I removed it thinking that might have caused the kernel panics)

Thanks!

What's your real intent with OpenCore?

• If your intent is VideoToolBox hardware assisted video compression/decompression/conversion (what is commonly called AMD hardware acceleration) is only supported with Ellesmere/Polaris and newer AMD GPUs, your HD7950 is 4+ years older than the the first GPU ever supported. So, it's completely useless for your GPU.
• If it's to run macOS releases after Mojave, keep it. If it's not and you are running Mojave, remove it.

Sounds good, I reckon I’ll keep Mojave for a little longer. Ironically opencore fixed a Bluetooth issue I was having where handoff wasn’t working, it’s still working after I removed opencore.

Any how’s. Thanks again for all of the guidance, I’ll report back with the results of the fix in a day or two.

So... according to what you wrote in the thread you attached... I'm in big $h!%:

Well under the recommended 30k - 35k, in this circumstance, should I do the 5 chime NVRAM reset? I read that doesn't work that well...
