Review on 🔒 OWC 32GB (4x8GB) DDR4 SO-DIMM PC4-19200 Memory Upgrade for 2017 iMac 27 inch with Retina 5K Display - 2400MHz by David Shah

I carefully installed all the sticks but my computer wouldn't turn on so I called Apple Support .They tried to help me but there was still no life on the screen.She offered to put my original Apple Ram in and the computer turned on so it was an OWC Ram that didn't work.I then called the OWC tech support and they had to insert each flash drive one by one and cycle my computer on and off each time This worked for 3 sticks but not all 4 so I'm returning this.
