Designed to help your system run faster and smoother, Crucial Laptop Memory is one of the easiest and most affordable ways to improve your system’s performance. Load programs faster. Increase responsiveness. Run data-intensive applications with ease, and increase your laptop’s multitasking capabilities. Make everything on your computer faster Memory is a component in your computer that enables short-term data access, which your computer relies on for moment-to-moment operations, such as loading apps, browsing the web, or editing a spreadsheet. Installing more memory in a slow PC is the easiest way to improve system performance quickly. Multitask with ease If you’re like us, you use your computer to do lots of things at once. You might be editing a document while also looking at pictures and browsing the internet. This naturally leads to a performance problem: every app you’re running requires memory and competes for a limited pool of resources. Overcome this by installing high-density modules in each memory slot on your laptop for seamless multitasking. Install with ease – no computer skills required With just a screwdriver, your owner’s manual, and a few minutes of time, you can install memory – no computer skills necessary. Just watch one of our three-minute install videos, and we’ll walk you step-by-step through the process. Don’t pay a computer shop to do something you can do in minutes! Maximize the value of your system At a fraction of the cost of a new system, a memory upgrade is one of the most affordable ways to increase performance. Get more out of your laptop by giving it the resources it needs to perform. Micron quality – a higher level of reliability As a brand of Micron, one of the largest memory manufacturers in the world, Crucial Laptop Memory is the standard for reliable performance. From the original SDRAM technology all the way to DDR4, we’ve engineered the memory technologies that have powered the world’s computers for 40 years and counting. Don’t settle for anything less. Review: It can work with Synology - I bought an 8GB RAM (part number: CT8G4SFRA266 2666MHz CL19 ) to extend the RAM of my Synology DS220+ NAS. Although Synology says the system supports up to 6 GB of RAM (2GB is included in the original box), the system actually supports more than that. You can add at least another 16GB of RAM to use as a cache to boost up the performance. I have read the previous comments – some claimed that CT8G4SFRA266 does not fit with Synology. This is not true. Mine works very well on DS220+. There are two possibilities why some people found it was not working: 1. They didn't correctly insert the RAM. You will need to first push the RAM very hard until hearing a clicking before lowering the RAM to sit on the RAM slot. There are many posts online where people claim the RAM doesn't work just because they didn't currently insert the RAM. 2. There are different variants of the Crucial memory "FRA266". Upon receiving the RAM, you will find that the RAM has another four digitals part number printed on the tag. Mine is shown in the photo, which is C8FR. This means the RAM is built using 8x 1GB memory cells, where both sides of the RAM have memory cells. This will work on Synology. This part number can also be C8FJ, which will also work too. However, if this part number is C4FE, it means the RAM is built using 4x 2GB memory cells, where the memory cells are sodered on just one side of the RAM. In this case, it won't be compatible with Synology. Unfortunately, you will not get to see this part number until you receive the RAM. I suspect this applies to the 16GB RAM, too, as there are some people online saying it works for Synology while others saying it doesn't. Overall, I am pleased with this purchase. Review: Great piece of kit - I brought this RAM one stick 16GB at 2666MHZ on the 1 of January 2021. I used it in conjuction with a single 8GB RAM already installed on my Gaming laptop. Nearly two years later and still going strong. I still get 60+FPS on games even though I use two different types of RAM sizes. Gaming performance never suffered. Its a plug and play type of kit, just install it into the memory banks and you're good to go. It came in anti static packaging so no need to worry about that like other sellers. Just ensure that you get that right type for your PC DDR4 and speed 2666MHZ. If your current ram is slower like 2400MHZ then your PC will automatically downclock the RAM to 2400MHZ or to whatever the slowest speed of your RAM is. So it is vital that your get the right type and right speed for your PC for value for money. Hope this helps. ## Features - Improve your system's responsiveness, run apps faster and multitask with ease - Install with ease; no computer skills required.

This wasn't the official recommended upgrade kit for the iMac Retina 5K 27-inch - 2020. However the spec was exactly the same and the price was much cheaper. Therefore, I decided to give it a go and I am really pleased I did. I watched a video on YouTube and it took less than 5 minutes to fit. The iMac has a little container on the back with a door that you release using a button under the power lead. Press the button, pop the old memory modules out, pop the new ones in - job done. I'm so please I upgraded. ## Frequently Bought Together - Crucial 16GB DDR4 2666 MT/s (PC4-21300) SODIMM 260-Pin Memory - CT16G4SFRA266 - Synology 2-Bay DiskStation DS224+ (Diskless) - Seagate IronWolf 8TB NAS Internal Hard Drive HDD – 3.5 Inch SATA 6Gb/s 7200 RPM 256MB Cache for RAID Network Attached Storage – Frustration Free Packaging (ST8000VNZ04/N004) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/228564889-ram-ct16g4sfra266-16gb-ddr4-2666mhz-cl19-laptop-memory](https://www.desertcart.tn/products/228564889-ram-ct16g4sfra266-16gb-ddr4-2666mhz-cl19-laptop-memory) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-25*
