It works. It didn't work immediately for me, as I did get the ram card missing beep code. After a while of cleaning and correctly seating it, it worked! Hasn't crashed ever since, 07/19. Don't mind the dirt and dust. :)

Arrived very quickly, and worked perfectly.  I had been worried that the low price would mean that there would be trouble with the quality, but such was not the case.

### ⭐⭐ 2.0 out of 5 stars







  
  
    Also used the expert installer option and they were fantastic. The RAM did not work from the get-go
  

*by M***I on Reviewed in the United States on December 27, 2017*

Purchased RAM for Christmas for my son's Alienware computer, as it said it was compatible. Also used the expert installer option and they were fantastic. The RAM did not work from the get-go. We got the dreaded "BSOD" numerous times all with different error codes. Took the installer several hours trying everything to get the RAM to work, alas nothing. Took out the new ram and installed the old. Computer is working fine, no issues whatsoever. Returning this product asap. Needless to say my son is not happy with his defective Christmas present.
