Review on 🔌 Timetec 16GB DDR4 2400MHz RAM Upgrade for Apple 2017 iMac (27-inch w/Retina 5K, 21.5-inch w/Retina 4K) – Compatible with iMac 18,1/18,2/18,3 by Juston Alonso

Good: - It's pretty cheap, $80 for a 16GB drive isn't bad! - Dispatched on time and delivered as promised. Bad: - I already had a 16GB Crucial stick along with the two 4GB sticks that came with my iMac. I had to try a lot (about 1.5 hours) to get my computer working. Every time it was in the wrong configuration I could hear the computer beeping/starting up but the screen just went blank. I finally got it working in a specific configuration (Crucial, timetec, apple_default_1, apple_default_2 from top to bottom). Although I'm not sure if this works for everyone.
