There was a problem filtering reviews right now. Please try again later.
I thought it was defective but the repair shop said that’s all it was. They’ve seen this happen many times over the years. Went from 8g to 64g. If it doesn’t turn on, they said just let it sit there for 10-15 minutes and then it turns on. Very weird as I’ve changed RAM in the past with no problems. In the end though, I’m happy with it. Once it started all was good.
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!

Für ungeübte Bastler ist der Einbau allerdings nicht unbedingt zu empfehlen, da man unter anderem sehr kleine Torx-Sicherheitsbits benötigt und auf jeden Fall etwas Zerlegeerfahrung mitbringen sollte, um alles schadlos zu bewerkstelligen. Mit etwas Erfahrung ist der Einbau jedoch nicht wirklich schwierig. Ggf. sollte man sich ein paar Videos dazu bei einem bekannten Videoportal ansehen.
Der RAM wurde direkt nach dem Einbau beim ersten Booten voll erkannt, in der Systemübersicht korrekt angezeigt. Es waren keinerlei weitere Einstellungen notwendig. Er funktioniert seit vielen Wochen vollkommen problemlos, auch bei heftiger Auslastung des Mac mini.
Ein weiterer Pluspunkt ist die lebenslange Garantie von OWC auf diesen RAM. Für schmales Geld kann man somit einem älteren Rechner nochmals ein verlängertes Leben schenken. 64 GB RAM machen sich ggü. 8 GB RAM massiv bemerkbar, was jedoch bei Kauf schon klar einkalkuliert war.
