It is most definitely the RAM chips. If you get 3 beeps a pause and then the beeps repeat. The RAM is definitely defective. I suggest getting new RAM and if it is new I would return it to the vendor for a replacement. You can call them up to get an exchange arranged. IFixit is really the best place to get your parts for Mac products IMHO. I won't use anyone else because of their customer support. I get outstanding service every time. Being a Technician, I replace parts often. I just had this issue on my own laptop for RAM I bought from them 2 years ago. I just bought a replacement just now when I saw this and had to let you know what the issue is and how to fix it.
