You are posting multiple post for the same issue- this is not advised.
As pointed out- you have a RAM problem.
RAM=memory
Storage = HD/SSD
You can try reseating your RAM
you can try one RAM at a time, and swapping banks if necessary to isolate the problem.
Most RAM has a lifetime warranty.
If this is a Retina machine your RAM is soldered to to the logic board and needs to be replaced.
