Crucial RAM 32GB Kit (2x16GB) DDR4 2666MHz CL19 Memory for Mac CT2K16G4S266M Green

Having recently purchased one of the last 2020 27" iMacs from Amazon I thought it best to future-proof it as best I can, so purchased some additional RAM for it bearing in mind it only had 8GB, so purchased this Crucial CT2K16G4S266M 32 GB Kit which consists of 2 off 16GB DDR4 2666 Ram chips. Unlike the smaller 21.5" iMac and some of the newer models, the Ram in the 2020 27" iMac can be easily upgraded, and yes I can confirm that it's very easy to do and has resulted in the RAM going from a paltry 8GB to a far more impressive 40GB because the old RAM chips can be retained. Sure the new iMacs are coming out, but they seem to be missing ports on the back, and realistically I'm not going to be rendering 5K videos for the foreseeable future, mainly YouTube, emailing, and some photo editing, so have purchased Affinity photo editing software so am well sorted. This has to be one of the easiest fixes to speed up your computer and will future-proof it for many years. The Crucial RAM upgrade has to be one of the best buys at the moment, and aside from changing the HDD to SSD or using an external SSD to store your files on if you have a tiny internal SSD drive there aren't really a lot of other steps you can take to make your computer run faster. Highly recommended if you have a 2020 (or older) 27" iMac and want to speed it up a bit.

Have used Crucial before and they are just brilliant. Such an affordable way to increase your RAM, instead of paying eye watering Apple prices. Just look up your computer specs on their website and you can find the RAM you need. So easy to install, a child could do it. Just remember to touch something to ground yourself prior to installation, so you get rid of any unwanted static while you complete the operation. Have updated all my Macs by using their RAM. Never had a problem, so happy to recommend. Quick delivery and always reliable.

I bought this RAM for my iMac, it is from a reliable company and is working perfectly, I recommend Crucial products.

OK for the price paid. Compact little kit

Used to add 32Gb (2 x 16Gb modules) memory on a new iMAC and used in conjunction with 16Gb pre-installed Apple memory. Works perfectly. I have used Crucial memory modules on MACs for many years and they have always been straightforward to install and reliable. They are very much cheaper than Apple's.

I bought a 2020 iMac 27" but was astounded at the price for RAM upgrades - so after a bit of a web search I found this as a viable RAM upgrade option. I was not disappointed in any way at all - it took me literally 2 minutes to install this and my Mac now runs like the powerhouse it should do, at a fraction of the cost that I would have paid if I had bought this direct. If you have upgradable RAM options in your Mac, do this now! I can now run GPU-intensive activities like photoshop and indesign in a flash and they run simultaniously without any lag whatsoever

Very easy to fit in 27” I Mac, up graded Ram to 40 Gb, just make sure they are pressed in fully.

Bit of,a bargain at this price, (£125), bought to upgrade a recently purchased iMac. Went from 16 to 40Gb and notice a lot of difference. Start up times appear to have reduced and no slowing or spinning beach ball when having numerous windows open. I use proprietary structural engineering software running under windows 10 in a virtual environment (parallels) with native Mac AutoCAD, as well as MS office and a other bits and pieces. Since upgrading I can run a windows on one screen and a Mac screen without any loss of speed, brilliant. Excellent value and a brilliant, simple upgrade.

Perfectly fit into my Mac. Authentic products.

I have an iMac Pro (2017, retina, 27", base memory 8GB) that I like except for the memory - it's too slow, and gets jammed up if I've opened too many programs. With great trepidation, I read the Apple specs to see what memory I should get to upgrade, found that the local shops didn't have much on hand, and decided to do it myself. The directions seemed straightforward, but this isn't my strong suit, and my hands aren't particularly strong, so I didn't know if I could remove the original memory or seat the new memory. I ordered a set of two 16GB memory chips for this model, and waited until someone was around in case something went awry who might be able to assist. Apple's explanation was very clear about how to add memory. I also read reviewer comments to see what problems others had encountered. The only hitch was in pushing the button to open the memory compartment - that needed more pressure from an implement other than my finger (e.g., a small screwdriver). I decided to try using the two empty slots, leaving the old 4GB chips in place, since it would still be balanced, and put the chips in (easily), closed up, put the cables back and the machine upright, and voila! It worked! my iMac is much quicker, and so far it hasn't frozen or "jammed up", so I'm very pleased with these chips. They have made a noticeable, welcome change, and I'm not feeling like such a klutz!

Esto a mi iMac del 2019 le vino de lujo. Pude elevar la RAM a 64 gb comprando dos veces este producto. El precio está muy bien, teniendo en cuenta de que ampliar la RAM en cualquier dispositivo es demasiado costoso.

Works well on my iMac and I believe it is a trustable brand for alternative RAM other than the original

Na installatie in IMac regelmatig een computer crash, na de-installatie was het over. Beetje teleurgesteld. Zijn speciaal voor Mac en werken niet naar behoren.
