DDR3, DDR2, DDR and SDRAM Memory RAM - latest speeds in memory
DDR3 is the latest in DDR memory technology, with newer Desktop Computer PCs, laptops, and servers requiring high-speed DDR3 has improved its memory speed. Compared to DDR2 over 100% and compared to DDR over 300%. DDR3 and DDR2 has 240Pin for desktop DIMMs, DDR SDRAM memory has 184 pins, where as SDRAM has 168 pins. DDR3 SDRAM Memory is a new type of memory that is able to triple the read / write speed of the previous generation of DDR SDRAM memory technology.
Different DDR SDRAM memory technology include the following: DDR3: PC3-8500 (DDR3-1066), PC3-10667 (DDR3-1333), PC3-12800 (DDR3-1600), PC3-14900 (DDR3-1866), PC3-16000 (DDR3-2000) DDR2: PC2-3200 400MHz, PC2-4200 533MHz, PC2-5300 667Mhz, PC-6400 800Mhz DDR: PC3200 400MHz, PC2700 333MHz and PC2100 266MHz.

Tools for selecting exact DDR SDRAM Memory Upgrades
DDR2 introduces some new features which allow it to ramp up to much higher speeds (with correspondingly higher bandwidth) and higher memory densities, all the while using less power. DDR2 memory uses a new form factor, a 240 pin DIMM (Dual Inline Memory Module) which is *not* compatible with current DDR memory slots. Upcoming chipsets by Intel and other manufacturers will support DDR2 specifically, and are not backwards compatible.
DDR SDRAM for desktop computers DIMMs have 184 pins (as opposed to 168 pins on SDRAM, or 240 pins on DDR2 SDRAM), and can be differentiated from SDRAM DIMMs by the number of notches (DDR SDRAM has one, SDRAM has two). DDR for notebook computers SO-DIMMs have 200 pins which is the same number of pins as DDR2 SO-DIMMs. These two specifications are notched very similarly and care must be taken during insertion when you are unsure of a correct match
