Panic report on iMac Retina 5K, 27-inch, 2019 [Solved out by RAM replacing from OWC to Crucial]

djivatma · Feb 14, 2020

Hi guys,

Could you have a look at this report, please:

What is this panic report about? What can be a reason for this?

iMac 19,1 (Retina 5K, 27-inch, 2019) Apple official refurbished basic model with 3 GHz Intel Core i5, 1 Tb FD, Radeon Pro 570X

I installed a clean version of Mojave 10.14.6 (18G103) and added 2 x 16 GB OWC RAM 2666MHz DDR4 PC4-21300 SO-DIMM 260 Pin (2666DDR4S32P), now I have 40 GB RAM in total.

I saw 2-3 times when my iMac crashed in the beginning when I restored OS Mojave from a Time Machine copy. Then I made a clean installation and there were no issues during all last week until now.

I tested RAM with Rember and Memtest86 and it was zero errors.

I run the system from the external NVMe drive (Sabrent 1TB Rocket NVMe PCIe M.2 2280 SSD + Sabrent USB 3.1 case EC-NVME)

Btw, in the DiagnosticReports folder I've found this:

Also, in the report is written: 'BSD process name corresponding to current thread: Google Chrome He'

Does it mean that the problem may be with Google Chrome? 🤔

Issue is with the OWC RAM

Hi guys,

Could you have a look at this report, please:

What is this panic report about? What can be a reason for this?

iMac 9,1 (Retina 5K, 27-inch, 2019) Apple official refurbished basic model with 3 GHz Intel Core i5, 1 Tb FD, Radeon Pro 570X

I installed a clean version of Mojave 10.14.6 (18G103) and added 2 x 16 GB OWC RAM 2666MHz DDR4 PC4-21300 SO-DIMM 260 Pin (2666DDR4S32P), now I have 40 GB RAM in total.

I saw 2-3 times when my iMac crashed in the beginning when I restored OS Mojave from a Time Machine copy. Then I made a clean installation and there were no issues during all last week until now.

I tested RAM with Rember and Memtest86 and it was zero errors.

I run the system from the external NVMe drive (Sabrent 1TB Rocket NVMe PCIe M.2 2280 SSD + Sabrent USB 3.1 case EC-NVME)

It's the OWC RAM. I just went through this with a brand new iMac purchased in Jan. I added 32 GB like you to the existing 8GB and right from the start the kernel panics happened. Returned the OWC and replaced with Crucial purchased on Amazon and have not had a single issue since.

Thanks a lot for sharing this! I've sent OWC memory back already

and ordered this memory instead:
Crucial CT2K16G4S266M Kit Memory for Mac of 32 GB (16 GB x 2) (DDR4, 2666 MT/s, PC4-21300, CL19, Dual Rank x 8, SODIMM, 260-Pines)

Yikes---I use OWC RAM and this is the first I'm hearing of an issue with it.

I see a lot of issues with OWC RAM on MacRumors which result in kernel panics, the main reason I would easily assume it would be the RAM is because it's the only thing you have upgraded, and since you are getting Google Chrome crash reports -- and since google chrome loves to eat up RAM, it would make it a bit more obvious to me.

I have 2 X 16gb OWC ram installed in my i9 Imac and have no issues. I have since added 2 X 16gb sticks of Crucial ram for a total of 64gb and everything works great! I found a local seller and picked up the 2 Crucial ram for only CAD$120!

Thanks for the feedback, guys! I installed new 32 Gb Crucial CT2K16G4S266M RAM today and will post updates here

djivatma · Feb 24, 2020

So far so good, guys! 🙌 I tried to overload my new Crucial RAM with a bunch of tabs in Chrome, with 5K video on YouTube, Rember test and Final Cut exports... zero panic reports or any issues! Thanks a lot!
