Fast delivery, works as expected - UPDATED
May 2021: Upgraded an iMac 2020 running Catalina from 8 Gb to 64 Gb. International delivery, expected this within three weeks but was quickly delivered in two. The upgrade was straightforward: unplug, place the screen face-down, open the memory door, remove original SO-DIMMs and replace with the new (slots 2 and 4). Works like a charm at 2667 MHz; not tech support needed. Following other user comments, I did not even try to use both the original and new SIMMs at the same time; may buy another 64 to max this out. End result: 64 Gb, no longer swapping although I am lately cutting it close. Very happy with the upgrade kit!UPDATED to Novembre 2021: Decided to max it out so I ordered another round of 64. Quick international delivery, slightly different packaging, installed in slots 1 and 3 (2 and 4 already filled with 32s). Slow initial boot, all 128 Gb recognized, but speed went down to 2133 MHz? Confirmed with Novabench and Geekbench. Unexpected. Visual inspection, it turns out all 4 chips are OWC, but each pair is visibly different and comes from a different manufacturer. I contacted support and after a quick exchange of emails, I tried swapping memory around. Success! The earlier batch went into slots 1 and 2, the new batch into slots 3 and 4 - 2666 Mhz reported, and the benchmarks recover that % lost to the earlier configuration.If I had to do this again, I would order all four chips in one go and save myself the hassle and the scare. Support responded brilliantly, thanks!
