What I have seen in terms of computer sytesm memory is that there are specs such as SDRAM, DDR and many others, that must fit the specs of the motherboard. If the computer's motherboard is kind of current and there are no main sytesm issues, updating the ram literally will take under an hour or so. It's one of many easiest computer upgrade techniques one can consider. Thanks for revealing your ideas in VIDEOS | DON'T SLEEP TOTAL FITNESS.
