Review on 💾 8GB PC21300 DDR4 2666MHz SO-DIMM Memory: Compatible with Mac Mini 2018, iMac 2019 and newer, as well as Compatible PCs by Kip Ruach

I've removed the two standard 4GB RAM sticks in my new 2019 iMac 3.0GHz i5 and replaced with two OWC 16GB -Sticks replaced by following the instructions online ( It's not difficult, but you have to know what you're doing.) The computer wouldn't start. I've tried different ways (e.g. different slots). It has Nothing changed. I called Apple, they offered to reset Apple the next day, try again with a new RAM to allow the computer to get used to its original memory (okay). After I put the Apple RAM back in , it started with no problems and I installed all the usual software. The next day I tried reinstalling the OWC RAM. Again it didn't work. No doubt it's right there. Also, Apple told me it worked on *should* (it's labeled 2666 DDR4). However, it doesn't work. I'll go back and leave this review to Pop Try to de-stress for about an hour.
