Hi. So recently I’ve Upgraded my iMac with Samsung ssd 860 evo 500gb
But every day I get kernel panics, randomly
Why? Any help appreciated
Update: what I've done
Apple hardware test - check
GPU stress test (heaven benchmark). - check
Installed clean Mojave - testing...

Catalina.
It was fusion drive. Now it is single drive
The error was like “ your computer restarted because of a problem. Press a key or wait a few seconds to continue staring up”
It is my boot drive
I’ve formatted it and clean install from internet recovery. hope that helps

for now I’ve clean installed Mojave. Testing on it.

Probably for the best.

To give it a major boost, replace that blade with a 970 EVO and the short Simtech adapter. The results will be 5–6x faster than that 860 and more than double the speed of the AHCI blade that was installed s part of the fusion array.

There are less expensive NVMe 3 x4 blades such as the Intel 660p but they’re a lot slower.

Download the complete Mojave installer to your 860 and run it from there when the time comes. The 970 cannot be used for internet recovery.

The late 2015 iMac was unique in that Apple upgraded to a 4-lane data bus but uses a 1 lane chip. WTF? Installing a 970 gives you the near equivalent of a 2017 SSD iMac but with Thunderbolt 2 instead of TB3.

No one says you have to do this anytime soon — or even at all — but, your 2015 has hidden, untapped potential if you ever want to access it.

Hi mikelhalloran! Just curious and wanted to learn. You said "Download the complete Mojave installer to your 860 and run it from there when the time comes. The 970 cannot be used for internet recovery." When will we need internet recovery? Like when the NVMe SSD is damaged or the OS gets corrupted or something? Also you mean it's best to have a backup internal SATA III SSD with Mac OS/Mojave installed just incase? Thanks a lot!

Normally any Mac from 2012 on can be set to factory specs through internet recovery. It must have had OS 10.7 or later originally. A 3rd party NVMe 3 x4 blade does not support this. This is a ground-up erase and restore. You boot directly into Internet Recovery and link to Apple for this.

This is not the same as reinstalling the current OS via the internet which can be done on any Mac running OS 10.7 or later. This reinstalls the OS only and does not affect data on the drive. Big difference. You boot into the Repair Partition for this.

With High Sierra on, you cannot boot into the Repair Partition if there’s any other Mac OS available on a partition or another drive.

However, you can boot from an external usb drive. You can install the Mac OS if there’s a complete installer on that drive. It can be a SSD or a USB stick, 8GB or larger (some newer cheap ones don’t work for this but most do.

The funniest part is that I choose SATA ssd because of stability. I’ve seen some issues on forums with sintech + nvme ssd. But the life is full of irony, right?
For now I would like to stick with SATA ssd, I just don’t want to fully disassemble imac. Still testing Mojave

Much appreciate for advice tho. I'm pretty sure you're right and the nvme SSD gonna make my iMac more powerful

2nd day on Mojave and no Kernel Panic so far. Seems like Catalina issue
