Introduction To Notebook Memory
This article explains about choosing the right notebook memory. Laptop memory was developed as a smaller, more space efficient alternative to the regular RAM memory used in desktop computers. Because of its smaller size, it allows laptop computers to provide more features for their size. RAM for desktop computers measures 5.25" long, and is generally 1.25" in height. To make a comparison, consider that laptop computer memory is almost the same height, but measures only 2.66" across. This cuts the amount of space required for memory in the laptop by 50%. In addition to all that, as you probably know, RAM in PCs stands upright to aid in airflow across the RAM chips, whereas memory in laptops is angled nearly flat to the board, with one stick partially overlapping the other when both sockets are together. The aim of this design is to increase the heat of the memory and at the same time, make it harder to cool, and it also significantly reduces the amount of space needed for the laptop ram memory.
Physically, there are four different formats of memory for laptops - 100-pin memory, 144-pin memory, 200-pin DDR memory, and 200-pin DDR2 memory. Each of these types fits in a different slot, and although the difference between 100-pin, 144-pin and 200-pin memory is really easy to see if you look closely, 200-pin DDR2 and 200-pin DDR memory look almost identical.
The most noticeable characteristic of 100-pin notebook memory is that it operates with 32-bit data transfer to a 64-bit memory controller in the case of notebooks. This means that as oppose to144-pin and 200-pin laptop memory, 100-pin memory requires two modules to be installed at the same time to properly be able to talk to the laptop, or it must work with a 32-bit memory controller.
144-pin notebook memory is an older notebook computer memory type that uses mostly SDRAM, although even older Extended Data Out and Fast Page Mode memory also exists. This type of notebook computer memory can range in size from 32MB - 512MB. 200-pin laptop memory is divided into two types depending on what type of memory it uses - DDR and DDR2. Despite having the same number of pins, the two types of memory are keyed differently at the bottom to prevent them from being installed in the incorrect slot. Both types come in sizes ranging from 128MB up to 2GB in the same module. DDR Memory comes in three different common speeds - 266MHz, 333MHz and 400MHz. DDR2 memory comes in a number of speeds as well - 400MHz, 533MHz and 667MHz. DDR and DDR2 memory can not work together because they are physically incompatible. Use Google as a laptop memory finder. There are different types of laptop memory cards. It's surely worth it to buy notebook ram and memory notebook ram. Get as much as possible memory laptop memory because memory notebook is very important.
