I'm still trying to determine if it is a serious problem. This topic was mainly to figure out what it could be, to save some time. If it keeps occurring a lot, I will send it in.
Defective RAM generally is a serious problem.
It can affect you in the middle of a game or anything, and if it decides to blue screen your computer while actively working with data it can become corrupt.
Case in point: My defective RAM made me BSoD while hosting a Minecraft server. Restarted the server with the same save and the chunks were completely glitched.
