subject: Memory Upgrade To Increase The Process Of Computers [print this page] While buying new Desktops or Laptops one should focus on configuration available, such as Graphics card, Computer Memory also called as RAM, Hard disk capacity, Operating system etc. This configuration plays a major role in all Computers. The Speed of any Electronic machines depends upon RAM. Hence Upgrade of RAM is necessary in all Computers. All computer manufacturers provide the required information in their websites about Memory Upgrade such as HP Memory Upgrades, Compaq Memory Upgrades, and Dell Memory Upgrades for their respective brands. These brands vary in quality as well as in cost; if the buyers have the basic knowledge about RAM then one may choose the high performance Memory Upgrade for the computer.
Size of RAM and how it Works
The size of RAM is always small, both in Physical size as well in amount of data it can hold. It comes in the form of modules that plug into the slots present in the motherboard and also in the form of separate microchips. Additional slots will be provided for Upgrade of Memory. These slots connect through a bus or wires to the processor. RAM is called as random access, since the storage location can be accessed directly, if you know the row and column that intersect any memory cell. The access time of RAM is calculated in nanoseconds and hard disk access time in milliseconds. Serial access memory (SAM) which is opposite to Random access memory stores data as a series of memory cells can be accessed sequentially. When Computers are switched off RAM vanishes instantly, but the Flash memory or hard drive stores whatever is on them, and this is the major difference between them. Computer Memory must be refreshed periodically else it gets discharge. The main purpose of RAM is to store and retrieve the information; it gives your computer a temporary place to process the data.
Types of RAM available
Different memory modules like DRAM, SRAM, DDRSDRAM and RDRAM have the same purpose but with different technology incorporated. These modules are not compatible with every machine so while purchasing the new module for Upgrades one must be careful in choosing the right module. PC2 4200 is a type of DDR2 and it has 240pin DIMM. This RAM is commonly used in Desktops. Problems may occur due to Memory Upgrades and incompatible current module, so products from trusted dealers with warranty period should only be bought.
512 MB PC2 4200 DDR2 RAM Memory refers the speed of the computer memory runs; in this case it is 512 MB. It uses the technology features of DDR2 which means that it consumes and works on a very lower voltage than the DDR and DDR2.
System issues due to RAM Upgrade
Before purchasing Memory Upgrades it is necessary to ensure the number of memory slots that are open? If slots are not open, then replacing the current RAM with advanced capacity one will be a better choice.
Then you have to make the choice for Type of sockets open, whether it is SIMMs or DIMMs? It is considered important in choosing the right module, because placing SIMMs into a board which uses DIMMs may result in lower speed. Also cache RAM Issues may occur, while buying RAM memory upgrade in pairs leads in issue of bus width.
