Size: 4GB Style: 2666MHz
The Crucial 4GB DDR4 2666 MHz CL19 Laptop Memory CT4G4SFS8266 is a great option for anyone looking to upgrade their laptop's memory. It's easy to install and provides a noticeable performance boost. I installed this memory in my old laptop and it made a big difference. My laptop was running slowly and I was constantly having to close programs to free up memory. After installing this memory, my laptop is much faster and I can run multiple programs at once without any problems. The memory is also very affordable. I was able to find it on sale for around $20, which is a great price for a 4GB stick of DDR4 memory. Overall, I highly recommend the Crucial 4GB DDR4 2666 MHz CL19 Laptop Memory CT4G4SFS8266 to anyone looking to upgrade their laptop's memory. It's a great value for the price and it provides a noticeable performance boost. Here are some of the pros and cons of the Crucial 4GB DDR4 2666 MHz CL19 Laptop Memory CT4G4SFS8266: Pros: Affordable Easy to install Noticeable performance boost Cons: Not compatible with all laptops May not be suitable for some users with demanding needs ... show more

    • Great unofficial RAM for your Synology 220+ NAS
Size: 4GB Style: 2666MHz
My current Synology 220+ RAM usage was constantly hovering around 70-80%. I started researching to see if any additional RAM could be added. You have a few options. You can go the Synology route and end up paying $90 for a 4GB stick. OR, you could purchase one of these for a fraction of the cost. Be aware that per Synology - you will void your warranty if you go with a non-Synology RAM. I took a leap of faith after much research and guess what?! This works perfectly. Installation was a breeze and my NAS recognized it immediately. It's been running so far for about a month with no issues. The best part? My RAM usage is now between 20-30%. Much better. I notice the OS runs a lot more smoothly as well now since the RAM wasn't being almost maxed out constantly. This is definitely worth the purchase if you would like to expand your RAM. Do your research. There are a lot of posts on Reddit that share the same success that I had. You could even go higher and get yourself a 8, 16 or 32GB stick. The 4GB was more than enough for what I use my NAS for (Plex and storage). ... show more
