Summary: Been using them now in two different computers (a set of 16 for both me and my wife), with a wide variety of use and condition. Sometimes the computers stay on all night for several days, sometimes they are off each night. Sometimes days of heavy gaming, sometimes heavy photo and video editing, sometimes just normal day to day use. Speeds maintain stable, no heat issues, no noticeable issues at all. Very pleased with this set of RAM and would highly recommend it.
