OS Sierra can't upgrade PPM002

All the Ram is stock. The computer is completely stock and hasn't been touched at all. I am not even sure a 3rd party makes Ram for this thing. I think it is all soldered to the logic board on this thing. Thanks a bunch for the Etrecheck tool. I will paste the results from it below. I have noticed that the computer needs restarted every so often or else the ram seems to get slow. I was assuming that was more of a software thing than the ram itself though.

Thanks for the reply. The onboard memory is the same as the memory stick that I was referring to. I realized that it is no longer an actual stick of memory after 2012, but I was meaning the same thing. I used to build systems and a memory stick is what everyone used to call the onboard RAM.

It seems weird that the onboard memory stops me from installing OS Sierra, but I can install El Capitan from time machine perfectly, and I can recover to the original OS just fine. I also did do the Ram reset upon boot up just in case that would help but it didn't.

Also, is there a way to get quote from apple to replace the onboard memory? I think I read that this requires replacing the entire logic board on this macbook. I might as well buy a new macbook before spending a thousand dollars to replace the onboard memory, and if I have to I can just stay with El Capitan because this macbook works great other than the fact I can't upgrade the software.
