That wasn't my buying intention. I ordered Micron memory and the sticks were 3rd party sticks with Micron chips. I design and build high reliability electronics equipment. In almost every case of equipment failure in my line of work, the problem has been traced to a marginal component. We are very careful about the components we buy.
Every component is required to meet mil-spec standards.
Every component we purchase is screened and tested and we still get bad components. Sometimes the screening house or the manufacturer is careless. Sometimes there are hidden and latent defects. I believe the answer is volume. Most Intel motherboards are made in-house.
