Does anyone know of where I can buy OEM Ram for a late 2015 5k? I have been having kernel panics and restarts. I took it into the Apple store, and they could not find anything wrong with it. After more research online, it appears that many people are experiencing the same issues as me after installing third-party ram into the iMac. I have 64 Gb of owc ram installed.
OWC has a lifetime warranty. Contact them about a replacement of your RAM.
I bought this type of RAM from Hynix
And upgraded a 2015 iMac 5k from 8gb to 24 and had zero issues (knock on wood )
It is available on amazon as well
Run memtest86+ to find out if the memory is defective. If it is, contact OWC for replacement.
