it can POTENTIALLY increase processing.....most computers out of the box will have for example 4gb of memory at the slowest clock rate 1066mhz but if you check what motherboard you have and see if it supports a faster clock rate then you can remove the 4gb @ 1066mhz and put in 4gb of 1600mhz memory and they computer will be faster but you might not notice the difference. Never mix memory because the memory will only operate as fast as the slowest DIMM(RAM chip). Increasing from 4gb of memory to 8gb of memory will only allow you to do more multitasking. hopes this helps...
