MP 1,1-5,1 Mac Pro flashed 5,1 Kernal Panic NVME Card?

[JonoMacNZ]

hey Guys,

Would appreciate some help.

Last wee while I've been getting random kernel panics, usually when the Mac isn't being used but not in sleep, ie when I get up to make a coffee and come back...

While another forum post stated it was compatable, I have a feeling it might be the NVME PCIE card I have running a 970 Pro

Dual M.2 NVMe Ports to PCIe 3.0 x16 Bifurcation Riser Controller - Support Non-BiFurcation Motherboard - SI-PEX40129

I have it installed in slot 4, in the x4 slots as would crash under load in the x16 slot. Have an externally power Vega Frontier on the x16 slot however these errors were occurring prior to it's install.

Have done a clean install and running Mojave 10.14.6 but the problem persists, have also resent SMC & PRAM. have also swapped out ram.

Next step is to revert back to SATA SSD and see if the problem persists but would like any comments in the meantime or if anyone has had the same issue with PCIE NVME controllers.

Model: MacPro5,1, BootROM 144.0.0.0.0, 12 processors, 6-Core Intel Xeon, 3.06 GHz, 64 GB, SMC 1.39f5

Thanks in advance.

I bet that your problem is not NVMe related or SYBA/IOCrest/ASM2824 related since everyone else with this card would had the same crash.

Take a look at this thread that people are tracking AppleIntelCPUPowerManagement crashes:
