  • The upgrade your iMac deserves
Size: (4x16GB) 64GB
I love Apple products, but let's face it, they're expensive. I have a 2019 27" iMac and it only comes with 8gb of RAM, which is close to nothing. Why it's still sold with only 8GB is beyond me. If you want to configure your iMac to have 64GB of RAM on Apple's website, it will run you an extra $1,000. Yes, that's not a typo, I didn't add an extra zero by mistake. A full extra thousand dollars. That's completely absurd. Well luckily, Adamanta provides 64GB at less than $300. Not only was it $700 cheaper, but it works perfectly, and I have yet to have a single issue. Installation was extremely easy as you would expect. Just open the hatch in the back, and replace the RAM inside with these. Would definitely recommend this RAM kit. You'll save A LOT of money. ... show more

  • Solid upgrade for my Mac Mini
Size: (2x16GB) 32GB
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... ... show more

  • Good stuff, works well...after stumbling with install.
Size: (2x16GB) 32GB
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! ... show more

  • Crashes iMac - Lasted 3 months
Size: (2x16GB) 32GB
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. ... show more

  • Perfect addition to my iMac
Size: (2x16GB) 32GB
Purchased a 27" 2019 iMac with 16GB RAM in it from Apple, then added this for a total of 48GB. I added this before the first boot up, so I can't compare before & after performance, but compared to my older Mac with 24GB, it's noticeably faster. Definitely worth the cost - especially compared to adding it at Apple. ... show more

  • Works great, but didn't play well with OEM
Size: (2x16GB) 32GB
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. ... show more

  • Awesome!
Size: (2x16GB) 32GB
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!!!
