Hello Everyone,

I recently bought a used Mac Pro flashed from 4.1 to 5.1.

I bought it with the original 512 MB Graphics Card and replaced it with the Mojave compatible Sapphire Radeon RX580 Pulse 8GB.

Panics happened already in High Sierra with the Original Graphics Card.

Clean install panics as well.

Installed Mojave on NVMe -> panics during installation, and right after login. (bootrom is 144.0.0.0.0)
Booted mojave from Hard Drive -> panics from 1 to 5 min after login .

the only panic report I could copy is the one down below, which is the one that happened when booting from HD.

NVRAM, SMC reset didn't result in anything different.
Firmware upgrade as well.
Safe Mode panics happened as well both booting from HD and NVMe.

I don't know what to do and I'm looking for help before I spend anymore money on this device.

Thank you very much for any help you can give me.

Run Apple Hardware Test to see if it finds any problems. You most likely have a hardware fault somewhere. I am guessing it is a RAM problem, but it might be something else.

How to use Apple Hardware Test on your Mac - Apple Support

Apple Hardware Test (AHT) contains a suite of diagnostics that test the hardware of your Mac.
support.apple.com support.apple.com

Let us know how it goes.

Edit: Apple Hardware Test should work on your system, despite it being flashed 4,1 > 5,1. See posts below for more details.

AHT does not work on a flashed 4,1 > 5,1

edit:

use of the 5.1 AHT will work in connection with an original apple EFI GPU

try:
Code: 
sudo nvram boot-args="keepsyms=1"
See if that will give more info, although the suspect here is AppleIntelCPUPowerManagement.
Try disabling hibernation.
 
Just a hunch, might be a RAM problem, badly seated or just bad memory(RAM).

Check if AHT runs, not sure if it does, there are a few conflicting posts above.

If you have more than one stick, try with 1 stick first, if a kernel panic shows up try with the other one(s)
There's too little information here on which MacPro you bought, it has 4 or 8 memory slots, but lets say you bought the one with 4 slots, all populated, get 2 sticks out, if it panics switch them with the other ones, if this is ok then one of the other RAM pair sticks is corrupted, you could them use just one of the sticks in the bad pair, if it panics you found the bad one, if not try the other one, it should give you a panic.

Welcome

The above is a bit vague, did you boot it both from a (mechanical) HDD and a NVME drive?
If you meant the NVME hard drive then I would definitely try to run boot it from a "normal" mechanical hard drive.

Looking at the log, it seemed like a bad CPU. Someone else in 2014 in this forum asked the same question with the same kernel panic log as you did with a similar CPU (X5690). When he replaced with a replacement CPU, the kernel panic went away.

Here is the link to that discussion.

Mac Pro 4,1 to 5,1 upgrade... New CPU causing kernel panic

Ok, so I am trying to upgrade my early 2009 Mac Pro that came with 2.66 quad core to a 5,1 with a 3.46 hex core processor. I have downloaded and upgraded the EFI to a 5.1 and went ahead and installed the processor, and then went to boot it. Now it won't boot in either 10.9 or 10.8, nor the...

try to reduce the number of components in your Mac to the minimum - there might be a failing component that is causing some electrical feedback or dust in a connector preventing a solid connection . So , remove all your memory modules except for the one in DIMM Slot 1 ( make certain its also a large enough memory module to run your OS ) , reinstall your GPU into a different , previously unused PCIe slot , remove your Optical Drive ( they often fail ) , remove any other PCIe cards like your M.2 drive card . I've had Macs exhibit your symptoms with just a malfunctioning PCIe USB Interface Card .

Do you have access to another Mac Pro 4,1 or 5,1 ?

I just noticed in your panic log that you have a Dual Processor Mac Pro 4,1 > 5,1 . The northbridge controller chip needs to be re-thermal pasted after a decade . It's the hottest chip in the System and if you don't keep it cool you'll be miserable .

Are the CPUs delidded properly?



If not it could be that bad contacts to the cpu sockets lead into ram banks not being recognized. If that happens while the machine runs it will crash.
 
Sorry for the late answer. It was my first post and I didn't realise I had to click watch to receive notifications.

Anyway The problem was with one DIMM. I took it off it and it's running properly now.

The panics were happening with both mechanical HDD (High Sierra) and NVme (Mojave). On High Sierra it usually ran for around 10 min longer though.

I coudn't boot to AHT in any way. I didn't try it after I took off the DIMM though.

Thank you all for helping me out!
