Review on 💾 High Density Crucial 4GB DDR3-1600 SODIMM 204-Pin Single Memory Module (PC3-12800) CT51264BF160BJ by Jason Rogness

so far so good. My Toshiba only had 2GB in 1 slot. I just doubled it to 4 to protect my laptop in the future. Plus OCZ ARC 100. Now I have Ultrabook speed. To update. 36% RAM usage with Google Chrome open. Instead of 72% with 2GB. Do that. My update from 08/28/15. I had 1 tab open on Google [Amazon] and checked the task manager for RAM usage. 1 left 1.7 GB and no SSD was used. You might think it's a waste. nope work in memory. if I had more TABS open [youtube, facebook] and no extra RAM. The CPU uses the hard drive and there is your clock lag. Invest in this memory card once in a lifetime [or twice]. It's worth your time.
