What is the difference between LPDDR3 and DDR4 RAM?
The key difference in LPDDR3 and DDR4 RAM is the number of pins (electrical connectors). The development and introduction of DDR4 RAM means that you will need to have a new motherboard with the appropriate sockets for it. DDR4 RAM is technically backwards compatible, but your experience may suffer. It only goes one way! Generally be sure to check before buying anything because DDR3 has been phased out or reduced in price.
RAM stands for Random Access Memory. A computer’s CPU constantly loads programs, formulates reactions, and performs calculations on stored information, all while the user inputs requests until they hit enter. If there isn’t enough space in there where this information can be stored (hence why computers come with a minimum of 4GB RAM), it is considered “random access” in that you can store anything in there, but what’s already there can’t be accessed directly. It’s so fast, however, that it can instantly see if something is in there before having to go through all of the information again to get what you want.
RAM modules come in many different formats depending on your computer system requirements. DDR3 RAM was introduced around 2007 and has since been phased out to be replaced by DDR4 RAM. DDR3 RAM modules are generally larger in size, with most measuring around 2 inches long by 1 inch wide or more.
Older computers that cannot handle the new standards of DDR4 will probably have to buy a whole new motherboard before it’s even possible to upgrade RAM. If your computer can’t handle DDR4 yet, don’t worry! DDR3 is still widely used and can be found almost everywhere.
