Not likely, at all. In fact, if the CPU was defective, you wouldn't likely be booting at all.
I think you are chasing a ghost, so to speak, and that your system is fine as is. Still you can verify whether your have a RAM problem or not very easily.
Once you do that and it checks out, you should be confident that what you are seeing is a matter of reserved memory for system resources and have nothing to worry about.
