I recommend using it if you are not sure of the type you need. I used their tool. It said this was the ram for my system so I came back here and purchased it. I opened my laptop, installed the additional ram, turned it back on, and that was all I needed to do. Everything just worked and the performance increase is quite noticeable - for a relatively cheap upgrade. My laptop is the Asus FX505DY FWIW. Review: Warehouse Deals - I recently purchased a laptop with the intention of upgrading its Ram to 16gb from 8gb. I had a look around to find an affordable DDR4 SODIM and struggled before checking desertcart Warehouse Deals. This was a returned item with some VERY minor imperfections. Managed to knock a chunk off the price for a small scratch on the label...Something I’ll likely never see again! Very easy to install in my laptop. Booted up and all showing correctly in CPUZ. Ran some tests to ensure no faults or errors and happy to say it was like new! Very happy with this purchase. Well worth checking out desertcart Warehouse Deals to save yourself a little extra if thinking about buying new! ## Features - Increases laptop performance - Easy to install - Compatible with OEM systems - 100% component and module tested for superior reliability - Available in DDR to DDR4 memory technology ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071KNKBQ1 | | Best Sellers Rank | 13,042 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 45 in Computer Memory | | Box Contents | Product | | Brand Name | Crucial | | Column Address Strobe Latency | 19 Nanoseconds | | Compatible Devices | Laptop | | Customer Reviews | 4.8 4.8 out of 5 stars (10,811) | | Data Transfer Rate | 2400 Megabytes Per Second | | Form Factor | SO-DIMM | | Global Trade Identification Number | 00649528780065 | | Item Type Name | Crucial CT8G4SFS8266 8 GB SO-DIMM 260-Pin, 2666 MHz / PC4-21300, CL19, Unbuffered, Non-ECC Memory - Multi-Colour | | Item Weight | 0.02 Pounds | | Manufacturer | Micron | | Memory Speed | 2666 MHz | | Model Name | Crucial 8GB (1x8GB) DDR4 SODIMM 2666MHz CL19 Single Stick | | Number of Pins | 260 | | Product Features | Registry Store | | Product Warranty | Limited lifetime warranty | | RAM Memory Technology | DDR4 | | RAM Size | 8 GB | | UPC | 649528780065 753459243732 | | Voltage | 1.2 Volts (DC) | ## Product Details - **Brand:** Crucial - **Compatible devices:** Laptop - **Computer memory size:** 8 GB - **Memory speed:** 2666 MHz - **RAM memory technology:** DDR4 ## Images ![CT8G4SFS8266 8 GB DDR4 2666 MT/s (PC4-21300) CL19 SR x 8 260-Pin Unbuffered SODIMM Memory - Image 1](https://m.media-amazon.com/images/I/71yLCwfhrsL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install and works flawlessly. *by B***N on 11 May 2019* Crucial's website has a useful tool where you can enter your model number and it'll show you everything they have that's compatible with your system.

And a decent Ram stick in general *by F***. on 14 July 2020* I have a 8gb laptop and I brought this ram stick to be able to play more intensive triple AAA games that would need more the 8gb. And this ram is was more then enough. The 2666mhz was defiantly fast enough to keep up with most demanding games. Also it took me like 15 minutes to install the RAM is and most of it is screwing and unscrewing the laptop. So overall I would suggest this RAM stock to anyone and everyone who wants extra RAM for any specific reason.
