Review on Crucial 8GB DDR4 2133MHz Memory - CT8G4DFS8213: High-Speed, Unbuffered DIMM 288-Pin RAM by Ryan Richards

I wanted to add another 8GB of RAM to my system on top of the original 8GB because I'm constantly using 95% or more of physical RAM . The new memory card arrived in just 3 days when it was supposed to arrive in 2 weeks. The memory card was packaged very well, almost superfluously - the DIMM card came in a clear hard plastic sleeve, which in turn was placed in sealed bubble wrap, and the bubble wrap itself was then sealed in a small, sturdy box. The new DIMM installed very easily and passed several memory tests (I ran the memtest86 package to test it thoroughly). I also ran performance tests before and after the install and the added RAM increased my system's performance, likely due to card interleaving. I actually ordered a slightly slower DIMM to match my existing RAM, but they sent me the next faster DIMM. But it works fine as the faster new DIMMs just run slower to match the speed of my old existing memory.
