Review: Worked perfectly iMac 2019 (latest) - best value + quality option found, - After investigating a good set of options to expand iMac 2019 (27'') memory, I end up going for 2x16gb Crucial. I bought both individually, not as a set which end-up much more affordable. I added 2x16gb side-by-side the original 2x4gb (Slot 1+3 -> added Crucial 16gb, slot 2 + 4 - Apple original 4gb memory). 40gb is enough to experience better performance, later the plan is to replace the apple 8gb with 2x more 16gb. Review: Great product easy installation - This was a great and easy way to add ram to my laptop, I checked using the crucial website which ram would fit, ordered it, watched the installation video on the crucial website and in 15 mins I had a laptop with an additional 16GB recognised and running. I'm of an age that did not have computers at school the best I had was a calculator, so she is not a barrier just do it and you will see the benefits. ## Features - Improve your system's responsiveness, run apps faster and multitask with ease - Install with ease; no computer skills required. How-to guides available at Crucial - Compatibility assurance when using the Crucial System Scanner or Crucial Advisor Tool - Micron quality and reliability is backed by superior component and module level testing and 42 years of memory expertise ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071KP8CGJ | | Best Sellers Rank | 22,231 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 101 in Computer Memory | | Box Contents | Product | | Brand Name | Crucial | | Column Address Strobe Latency | CL19 | | Compatible Devices | Laptop | | Customer Reviews | 4.8 4.8 out of 5 stars (4,673) | | Data Transfer Rate | 2666 Megabits Per Second | | Form Factor | SO-DIMM | | Global Trade Identification Number | 00649528780140 | | Item Type Name | Crucial CT16G4SFD8266 16 GB SO-DIMM 260-Pin, 2666 MHz / PC4-21300, CL19, Unbuffered, Non-ECC Memory - Multi-Colour | | Item Weight | 0.02 Pounds | | Manufacturer | Micron | | Manufacturer Part Number | CT16G4SFD8266 | | Memory Form Factor | SODIMM | | Memory Generation | DDR4 | | Memory Speed | 2666 MHz | | Model Name | CT16G4SFD8266 | | Model Number | CT16G4SFD8266 | | Number of Pins | 260 | | Product Features | nv: AMD Validation^AMD Ryzen | Business Program | Crucial | Component Configuration | x8 Based | Configuration | 2048 Meg x 64 | DDR Timings | CL=19 | DIMM Type | Unbuffered | Density ^16 GB | Error Checking | NON-ECC | Megabyt® ES 163 8 4 | Memory typ^DDR4 PC4-21300 | Module Rank^Dual Ranked | Package^260-pin SODIMM | Platform Category^DDR4 | Speed^DDR4-2666 | Voltage^1.2V | VolumeDiscountBucket^… | | Product Warranty | Limited lifetime warranty | | RAM Memory Technology | DDR4 | | RAM Size | 16 GB | | UPC | 696551661687 649528780140 | | Unit Count | 1.0 count | | Voltage | 1.2 Volts | ## Product Details - **Brand:** Crucial - **Compatible devices:** Laptop - **Computer memory size:** 16 GB - **Memory speed:** 2666 MHz - **RAM memory technology:** DDR4 ## Images ![RAM CT16G4SFD8266 16GB DDR4 2666MHz Laptop Memory - Image 1](https://m.media-amazon.com/images/I/71oz85Vv6mL.jpg) ## Available Options This product comes in different **Pattern, Size, Style** options. ## Questions & Answers **Q: Hi. is the "crucial ct16g4sfd8266 16 gb " compatible with pavilion 14-ce2068st?** A: It was for my pavillion. Just buy ram with speeds the same or slower than what you have at the momment. Check your ram speed using the bios **Q: Hi. is this ram fit to hp omen 15 ax- 009na ?** A: If you're unfamiliar with the specifications, Crucial has a tool on their website that will tell you what is compatible with your exact machine. Of course, you don't need to use their own brand, but I've happily been Crucial for upgrades for over 15 years. **Q: Does this work in an dell xps 15 9560 model laptop** A: Check with the Crucial UK website. That will tell you the answer **Q: Will this work on a Msi gs75 stealth 8se gaming laptop?** A: If you go to cruscials website and put in your laptop model it will list the memory that they guarantee to be compatible. That easy way to make sure. Remember the max ram you can have in your laptop is 32gb so keep that in mind and make sure you don't have that much already. Mine had 8gb so I added the 16 to give 24gb. But that was more do to other reasons than doing best thing. For reference I have a MSI GL75 9sd and this ram works perfectly. And this ram is correct type and speed for your machine but best to check for yourself be going to crucial compatibility site or on the MSI site for specs. Rather than just listening to random dude on here. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked perfectly iMac 2019 (latest) - best value + quality option found, *by A***O on 11 May 2020* After investigating a good set of options to expand iMac 2019 (27'') memory, I end up going for 2x16gb Crucial.
