Every laptop has within it a hardware logic circuit called the memory controller. This is the part of the system that, well, controls the memory. It generates the necessary signals to control the reading and writing of information from and to the Lap top memory, and interfaces the Laptop memory with the other major parts of the system. The laptop memory controller is normally integrated into the system chipset.
Buying more Laptop memory, also commonly known as RAM (Random Access Memory) for you laptop can be the cheapest and easiest way to give your laptop a speed improvement. Laptop memory provides a place for the system to store information before writing or reading it from the hard drive and memory is also allocated to allow programs to run.
Installing more memory is the cheapest upgrade for your laptop. By increasing the amount of RAM you have in your system the greater the temporary storage for it to work with when running programs and applications.
Especially when using software to edit large files such as digital photos and videos alongside simple tasks such as just loading your computer with more RAM Windows will load faster and allow you to open and close programs quicker so that you can truly multitask.
Below is guidance about the different memory for Laptop types avilable, to ensure compatability please check your motherboard manual or related website for advice.
DDR Memory (184-pin DIMMS). These were introduced in 2002 to replace the earlier SDRAM format. To use this type of memory you need a 184-pin socket for the module to fit into.
DDR Memory is available in different speeds of PC2100, PC2700, PC3200 (DDR400), and PC4000 (DDR500). The modules can be used singly or how desired however you cannot mix different speeds together.
DDR2 Memory (240-pin DIMMS). This format builds on the technology of DDR. This standard has more pins and its main developments are the ability to run faster whilst consuming less power.
To use DDR2 memory you need a 240-pin socket for the module to slot on your motherboard. DDR2 Memory is available in many different speeds including PC2-3200 (DDR2400), PC2-4200 (DDR2533), and PC2-5300 (DDR-667).
The modules can be used singly or how desired you can install different speeds of DDR2 memory together if your motherboard supports the faster speed however faster modules will perform at the lower speed.
This may be worth considering if you want to run Dual-Channel memory where you must use the same speed and ideally matching pairs to ensure compatibility.
There are more memory for Laptop types as:
Acer Laptop RAM
Apple Laptop RAM
Compaq Laptop RAM
Dell Laptop RAM
Fujitsu Laptop RAM
Gateway Laptop RAM
Hitachi Laptop RAM
HP Laptop RAM
IBM Laptop RAM
Sony Laptop RAM
Toshiba Laptop RAM
Types of memory for Laptop
Most of the laptops are now using the DDR2 memory specification, but a number of new laptops use the DDR3 standard. In addition to the type of memory installed in the laptop, the speed of the memory can also make a difference in the performance. When comparing laptops, be sure to check both of these pieces of information to determine how they may impact performance.
There are two ways that the memory speeds can be designated. The first is by the memory type and its clock rating, like DDR2 400. The other method is by listing the type along with the bandwidth. In the case the same DDR2 memory would be listed as PC2-3200 memory. Below is a listing in order of lowest to fastest memory types in both formats:
* DDR2 400 / PC2-3200
* DDR2 533 / PC2-4200
* DDR2 667 / PC2-5300 or PC2-5400
* DDR2 800 / PC2-6400
* DDR3 800 / PC3-6400
* DDR3 1066 / PC3-8500
* DDR3 1333 / PC3-10600
* DDR3 1600 / PC3-12800
Most laptops today have a small door on the underside of the system with access to the memory module slots. If it does, then it is possible to just purchase a memory upgrade and install it yourself without much trouble. A system without an external door or panel for memory access will require installation by a service technician. This generally will add additional expense to the memory upgrade in the future or possibly even the requirement that the system be sent in to a service center which means the lack of a computer until the upgrade is completed.
Hope this short news can improve your memory for Laptop
