Memory Desktop and Laptop

The most practical of determining if how much memory you need for your computer is looking how will you be using the computer for.  Before picking an application software or the latest high-end games try to have some time by looking at the system requirements of the software.  Most vendors of these software usually print it at the back of the disk package stating the minimum and recommended requirements for the memory and processor.  Also try to consider how much memory the PC is able to support, most desktops are able to go up to 4 memory slots on the motherboards.  Motherboards with mATX form factor usually have two RAM slots.

SO-DIMM
Small outline dual in-line memory module (SO-DIMM) is smaller and is used in  laptops, notebook computers, upgradable printers, and routers.  SO-DIMMs consists of memory components attached to a printed circuit board.  Available in 72, 100, 144, and 200 pin packages.    They are the essential where space is a primary concern but still achieve the ideal power.  Most SO-DIMMS have speed and lower power consumption available in 512MB, 1GB up to 2GB.  Newer DDR3 SO-DIMMS manufactures 75nm technology promise a reduction in power consumption as they take advantage of DDR3s low power requirements, thereby reducing power usage on most laptops and notebooks.

SDR
Single Data Rate  (SDR) allows the CPU to access memory at 25 percent faster than EDO memory.  SDR SDRAM was the first  DRAM supporting clock-synchronous transfer of data.  SDR  technology uses a clock to synchronize signal input and output of a memory chip and coordinated with the CPU clock so that their timing is synchronized and increasing efficiency of data transfer. This importantly boosted the bandwidth with fast page mode and EDO RAM.  SDR SDRAM is still made available by some manufactures and being used today although DDR memory is now the lowest cost available in the market.
