## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Works great in Dell 2 in 1 laptop
  

*by M***K on Reviewed in the United States on April 16, 2019*

Works great and was recognized without issue in Dell 2 in 1 laptop I recently purchased. The laptop was having an issue running multiple programs at the same time with only 4 GB installed. It was such a good price I figured adding a stick of RAM is cheaper than the price difference between a higher end laptop. The added RAM has solved the lagging between switching apps and loading website pages now works better than I could have hoped.

### ⭐ 







  
  
    It works at 2400 MHz not at 2666 MHz.
  

*by R***N on Reviewed in the United States on May 16, 2020*

This memory runs at 2400MHz on my laptop even though it says 2666MHz on the product spec. The reason is that 2666 is not standard JEDEC speed on this RAM. It is only supported with special BIOS settings (XMP- extreme memory profile) which is mostly available on gaming machines only. So please make sure your BIOS supports XMP. Otherwise this RAM will run at slower 2400 MHz instead of the advertised 2666 MHz.

### ⭐⭐⭐⭐⭐ 







  
  
    work fine as long as you know correct memory format for your computer.
  

*by Y***. on Reviewed in the United States on April 28, 2020*

For the price, this is a very good memory stick for laptop.  make sure you read your computer/laptop guide book make sure it is the correct format and correct voltage for your computer/laptop.
