A Guide To Buying DDR Laptop Memory
If you are about to purchase laptop memory then you will hear about DDR memory which essentially means that it is memory that will help to improve your laptop’s speed. To a person that knows about DDR there may be other meanings attached to the term besides making a laptop work faster. There are for instance different DDR’s to know about including DDR, DDR2 and then there is also DDR3. DDR or double data rate is definitely useful if you want to compute faster and it certainly helps to quicken the process of transferring data from the laptop hard drive to its memory.
In regard to understanding what represents the right laptop memory it is necessary to understand that the more information that can be loaded into the memory the less is the need to go back to the laptop hard driver which means less time spent between drive and memory and this means faster laptop operations.
When you look for DDR memory you will come across another term which is DDR SDRAM which means DDR memory with Synchronous Dynamic Random Access Memory which in turn means getting double bandwidth as compared to SDR (single data rate) and this means that data will also be transferred twice as fast between hard drive and the system memory.
When it comes to picking the right sort of DDR you will need to pick between DDR and DDR2 and also DDR3. Each works at different speeds with DDR2 boasting of speeds between 100 and 133 MHz while DDR3 works at speeds between 166 and 200 MHz.
Before you actually buy additional memory to add to your laptop you have to first determine whether your laptop supports a particular type of DDR memory. It pays to know that installing the wrong DDR memory can lead to your laptop breaking down and so you should only install memory that is supported by your laptop.
Furthermore, your laptop will have a distinct hole in which to affix your DDR memory and each different DDR memory type has certain pins that will fit in exactly into the hole. So, it is also necessary to match the pins before buying your DDR memory and remember also that it is not possible to install the memory in reverse order.
It is also important that before you actually go out and buy laptop memory that you find out for sure that your laptop can indeed support that type of memory and also the memory speed. A rule of thumb is to pick memory speed that equals or exceeds the speed at which your laptop functions.
