I ordered these memory chips because I (Office, etc.) robust and reliable storage for everyday use required. Previously, I had a brand with extra glued coolers that should be supposedly faster and even "cooler". This worked well for a while, after approximately 1 year crashed the PC, because the chips were defective. This was due to the glued-cooler, the most affected by their weight, the electrical connections. That's why I wanted chips without this cooler. I use the new chips for almost a year and have not regretted buying a single time. They have never led to a crash and even various games (Anno, Skyrim, Dragon Age, etc.) run smoothly.
