Should You Switch From From DDR2 to DDR3 Memory ?

Many motherboards support using both DDR2 and DDR3 memory, but the only problem is that the processor used can dictate which type of memory is acceptable to install. For example, using an Intel Core i7 or i5 processor means you're going to have to use DDR3 memory, no matter what your motherboard supports. On the other hand, some processors only support DDR2. So be sure to read your motherboards instructions carefully, otherwise you could end up wasting your money.

Now, with that being said, if you find yourself in the position of having to choose between both types of memory - and there are no technical hurdles in the way - then this becomes a question of price versus performance. DDR2 is very economical. Well, to put it bluntly, DDR2 memory is cheap. DDR3, in comparison, is pretty expensive. While you do get a slight performance advantage with DDR3, the real advantage is your ability to upgrade. DDR2 is old technology, and it's slowly being phased out (slowly being the key word here). In the future, almost every computer will use DDR3 memory, and upgrading from DDR2 is going to be a hassle. On the other hand, you can get a lot more memory by buying DDR2 now. In fact, you can get almost double the amount of RAM by buying DDR2 memory instead of DDR3. For those that recall the transition from DDR1 to DDR2, the move from DDR2 to DDR3 will be much the same. It will take years for DDR3 to become main stream.  Lastly, those with a DDR2 motherboard have nothing to worry about as DDR2 production will continue with even improved parts still on the drawing boards.
