I don't think you understand what RAM does. Random-access-memory only accesses memory functions. There is no function that would ever call for 64 gigabites of ram. Ram is limited not by the CPU but by the Operating system. There is no need for more RAM then what is supported by your operating system. If you think RAM renders images, videos, animations etc it doesnt. Processors do that work along with Graphic Cards. Increasing the graphic cards RAM and increasing the amount and speeds of your Processors are what makes things work quicker.
