I was convinced that I could only put 64gb of ram in my z420 but after watching a YouTube video from Cloud Ninjas and checking their website I decided to pick up 256gb in the hopes that it would work. The package shipped and arrived quickly and we'll packaged. Within 5 minutes I successfully went from 8gb to 256gb. Couldn't be happier. I even took the time to upgrade my processor from the suggestions in that very same video.
