Adamanta 32GB (2x16GB) Memory Upgrade for 2020 Apple iMac 27" w/Retina 5K Display, 2019 iMac 27" w/Retina 5K Display, 2018 Mac mini DDR4 2666Mhz PC4-21300 SODIMM 2Rx8 CL19 1.2v DRAM RAM

I'm really picky about what components I use to upgrade my computers - but, this one rocks... Apple charges an obscene amount of money for memory upgrades, and given the low price of this memory, I hesitated thinking it wasn't compatible, or I'd get an error code on boot, or it would fail? But, fact is - this memory simply works - at speed - without any errors. I upgraded my 2018 Mac Mini to 32GB from the factory installed 8GB and I do some fairly intensive memory apps for photo editing, and my system has been rock solid since this upgrade. I know this memory brand isn't a "household name" - but, it simply works as advertised and is flawless so far after some hard use. Would buy again, for sure...

I bought this memory to upgrade the memory in my new IMAC. It was super easy to install and it works great. It was soooo much cheaper than Apple’s memory! I just watched how to do it on YouTube. Easy. Reasonably priced. It was a “bang for your buck” purchase. I’m very happy!!!

As with other leading manufacturer, did not work when installed and after jostling around cards per Apple instructions. Finally had to remove both original 4gb cards & follow Adamenta's instructions that came with ram. Install one 16gb & boot up. Add 2nd 16gb & reboot. Then add original two 4gb cards & reboot...WA-LA! Worked. Shows 40gb & working at the correct speed. Seems Adamenta knows more about this than Apple! 😁 Happy camper! Thanks Adamenta, good job!

Thanks to Apple's forward thinking, the 27 inch iMac from 2017 onward allows for the easiest memory upgrade of any computer I have touched. Memory cards went in as easy as could be possible--snap, snap. Ran a quick test and had an all green board. Excellent price for an excellent product.

I was looking for a RAM upgrade for my Mac mini, this one was perfect, works as expected and you can obviously tell the difference when using the computer. Is not that easy to install because of Apples Mac mini design but it is just a matter to follow any YouTube tutorial to put the part into the computer. I totally recommend it as it works perfectly and you will be saving a lot of money compared to Apple's retail price when buying the computer.

iMac 27" 2020. Worked fine for a couple months. This week, 3 months later, my computer started crashing a couple times a day. I tried starting up in recovery mode, and it said everything was fine. Still wouldn't start back up. Replaced the ram with the stock Apple ram and everything's fine again and running smoother than it has been for the past couple weeks. So it's gotta be this RAM right? Probably fine for PCs but I wouldn't use this RAM in iMacs.

Works great, and it's a huge improvement - the original 8GB that came with my iMac was definitely not sufficient. 32GB is clocking at full speed and working perfectly making my machine ultra responsive even with 20GB in use by apps, but the new modules didn't play well with OEM - it would not boot up with mixing and matching the 2x4GB and 2x16GB in any order, but still definitely worth it.

This was a snap ! very easy to install

J'ai un IMac 27 pouces 2020 avec un i7 8 cœurs de 10eme génération et 8Go (2x4Go) de Ram. Le but était de passer à 40Go en ajoutant 32Go (2x16Go). Après l'ajout des barrettes, le mac n'a pas voulu démarrer, elles étaient pourtant bien enclenchées. Par acquis de conscience, j'ai inversé les nouvelles barrettes et les anciennes et plus de souci ! Les 4 barrettes (40Go) sont détectées correctement et ça a l'air de fonctionner. Seulement 4 étoiles parce que je n'ai pas encore poussé la bête donc à voir sur la durée. Produit reçu le lendemain, bien emballé, et qui fonctionne alors à ce prix là, faites vous plaisir !

Las memorias perfectas, fueron súper fácil de instalar, al principio no las reconoció pero al instalarlas de a cuerdo al instructivo que viene en la cajita, las reconoció sin problemas y mi máquina ha estado trabajando Perfecto, altamente recomendable

2020imac27インチで確認。コスパは最高ですが、同梱の説明書通りのスロット設置位置だと速度2666Mhzが出ませんでした。Amazonの製品説明書画像のが正解です。他の情報にもありますが古いメモリから下から純に刺すのが正解のようです。製品自体は設置後10日ほど経ちますが今のところ問題ありません。

The rams work great with Mac Mini 2018/2020. No issue so far. But need to be wary of getting the correct screwdriver for Mac Mini and you will have no issue installing them. The issue I had was that I installed the ram incorrectly causing 1 of them to be not detected and when reassembling Mac mini the Fan in the Mac mini stopped working. So I had to re-do the ram and fan connection. Otherwise all are good.

Upgraded my 2020 Mac mini Ram. The DIY experience was nice. All working well.
