Maximizing the system's memory may be the best and easiest performance upgrade anyone can do and a Samsung makes a very sound product. I would say that these SODIMMs well compare with Crucial and other premium makers for RELIABILITY. Just ran a proprietary version of MemTest that's burned into the Dell BIOS to completion and all tests passed with no errors. Usually, when this happens (and you don't do something to the memory to damage it, eg: static zap, submersion in water, etc) your memory will work for the life of the system. Just like Crucial, Samsung makes not only the SODIMMs, but also the chips on them. So, they can do quality control all of the way through the manufacturing process. Reading my chips' SPD with CPU-Z, I see mine were made a few weeks apart in 2011. They were likely integrated into a system and sold with 3 to 6 months later and memory has been running off and on since then with no detectable issues, now. I'd say that's a pretty good long haul overall and still running.Read full review
