Different RAM vendors on 2019 iMac?


Topic starter

On a recent episode I recall hearing that using different RAM vendors on a 2020 iMac was not supported. I confirmed this by going to Apple's website, and noted that this only seemed to be the case for this year's model. However, after installing 2 x 16GB from OWC on a 27" 2019 iMac that already had 2 x 4GB installed, the client is reporting unexpected crashes. I'm wondering if anyone has ideas as to what the issue might be? Screenshots attached of System Report.
