RAM CT16G4SFD824A 16GB DDR4 2400MHz CL17 Laptop Memory

I bought this for my partner as she has the ThinkPad E580 laptop with only 8GB of RAM. A video on YouTube gave clear instructions of how to remove the backing of the laptop. The RAM can then be easily inserted into the second slot giving a total RAM of 24GB. This has made a huge impact on the performance of the laptop, making start ups, running programs, and general use a LOT smoother. It was glitching and lagging a lot before hand as the CPU and RAM was constantly at 100% performance. According to my partner, the CPU rarely goes over 20% performance. Anyone out there with a laptop that is compatible with this RAM, I would highly recommend it to you. It is worth every penny!

It arrived in simple transparent plastic packaging. Followed instructions on how to install the RAM into my iMac from the Apple website. Make sure you follow the section for the correct model. After restarting my Mac, screen remained dark few seconds longer than usual and the loading screen was also slower. This is normal as the RAM is being initialised. When the machine eventually started, I tested out various apps e.g. photoshop, GarageBand etc and they all ran noticeably smoother. The other test I carried out was to run Windows X on Parallels. On 8Gb RAM it was sluggish. With 24GB RAM it runs as smoothly as if I had run it via Bootcamp. Games which previously were unplayable ran smoothly. For the price, it is amazing value for what it can do for your Mac.

Product and price, absolutely great!! Fitted like a charm, I have an HP Pavilion All in One and this works straight off the bat. I plopped them in, powered on and the machine took care of the rest. Doubled checked the system details and 32GB showing up. Can run After Effects a lot smoother now and a few of my usual go to games, are now running slicker in higher settings. Packaging was a little concerning, was in an easy to open blister pack off the shelf, but flung in a cardboard envelope, free to rattle around. A folded sheet of bubble rap would have been more reassuring. However, item arrived intact and works fine.

Apparently easy to install (but I played safe and got a local shop to it for me), there are videos on Youtube explaining how to do so. Doubled my available memory from 8gb to 16gb, I've not noticed any speed difference but thats down to not having it long before I upgraded plus the nearest I get to a 3D game is playing GZDoom, hardly a benchmark I know. I paid a local shop to install this as I also needed them to install and migrate a 1tb SSD drive (Was 128gb) which I subsequently split into 2 partition for Windows 10 & 11. Openshot and DaVinci Resolve have been a lot more stable than when I tried using them on a 4gb Lenovo T410. The machine I'm using only takes one SODIM memory board but for now 16 gigs seems to be plenty for everyday use and the occasional bigger project. I hope to get a few years worth of use out of it anyway.

I have one of the moduels fail on me after a few months. i am currently going through the replacement process on the garentee. I can not fault the customer service and you do have to pay P&P to send them back cost me around £7 Up untill the point it failing they work very well and my laptop got a new lease of life. its a risk with any electrial item that they fail some point. just not a few months down the line I still have no reservations about recommending this produce to anyone they work and you will get the odd one that like mine didnt last long. its the nature of the product

Excellent quality 👌

Really easy to install memory, just check via the "About this Mac" page for instructions and confirmation of what memory type your computer takes. They come in a stiff blister pack, so they are well protected in transit I was pleased to note that I did not need any special tools to install in my 27" iMac 2017 I did read a note on another post that is matters as to what slots you put different pairs of memory, so if you are having difficulty in re-starting your computer, just check which slots they are in, I think I put these into slots 2 and 4, with the original 2 x 4Gb chips in slots 1 and 3 - but check with the manufacturer if you have issues because this memory definitely works. There are other reviews which say which slots they have put them in, depending on the model year of the computer.

I've been using Crucial Memory products for over 20yrs, and have seen only 2 or 3 failures in all that time. If you use the search tool on the main Crucial Website to find out what works with your system, you cant go wrong. Just make a note of the part number & go shopping.

I dont know when i buy it but after years it is working perfectly

It fits perfectly with easy installation on my Lenovo Legion Y720 and works great with no issues.

working as expected... 👍

I was in a fix between Corsair and this one. Chose this because it's around 4K cheaper with all features remaining the same. Also Corsair was from Global store which has it's own hassles if something goes wrong with the product and I have to return it. I got 32 GB in total (two 16GB sticks) for my Intel NUC. I mainly use my system for virtualisation which needs a lot RAM. Also, RAM is something which I don't want to upgrade so maxed out the capacity. Using it now for 2 days and the speed is amazing, much faster than my laptop which has 1666 Mgz frequency. Would definitely recommend this one over others for price / performance ratio.

Sin problema hasta el momento, funciona muy bien, ayudo a mejorar el desempeño de mi laptop de 2019. No fue difícil de instalar.
