What we wud need and have to heavily rely on wud be a virtual memory management model which relies on storage memory(typically HDDs).Upgrading from 4GB to 8GB worth of RAM(and having a slow HDD) so as to handle '16 million GB' worth of page translation wud be a teeny tiny modification though some processes wud definitely loaded faster or some heavy apps cud become snappier and more performant since no. In order to handle these '16 million GB' logical addresses and map them to the physical memory u wud literally have to have a RAM module worth the eiffel tower or even empire state building.This is in no way possible to implement. This is almost unthinkable beyond quantification. of logical addresses created wud be 2^64 i.e.

Having a 64 bit processor means the total no. Now take modern processors having 64 bit architectures. of pages created is worth 4GB.A quick 4GB upgrade should fix the problem leaving virtually no possiblity of a page fault

Theoretically that means no virtual memory wud be necessary since the RAM alone wud capable enough to handle the processes when the page translation takes place (from logical address to physical address).This scenario is very much achievable (atleast theoretically) in case of 32 bit processors as the maximum no. Now, consider a 32 bit processor which will have 2^32 logical addresses( worth 4GB) will have to have 4GB worth of RAM for absolute performance. physical memory based on the page table and page size of all those running processes. RAM won't help if the needed amount is saturated.Ĭorrect me if i'm wrong but RAM upgrade which basically meaning is your physical memory, when upgraded, can help you have little less number of page faults.During the time when page translation takes place the logical address space needs to map the active processes onto the RAM i.e. Thus a faster hard drive is needed for a better overall performance in processing. Processors generally need to wait for the hard drive's read/write operations which are a lot slower. In today's computers, the bottle-neck of processing is usually the hard drive.

Mac OS X operates very efficient with 8GB of RAM. Other than that, this will most likely not be necessary.you do run Virtual Machines excessively because you need to allocate a lot of RAM to the virtual OS.
