The speed is backward compatible but will need the motherboard to be compatible. The latest generation of memory technology, DDR3, began to appear in systems in late 2007. DDR3 modules achieve this high level of performance while using up even less power than DDR2 modules. It is the improved version of the DDR2 SDRAM. The number of DIMM pins remains the same however we cannot use them in the same way with motherboard as in the case of DDR2, the difference in version results in the pins configuration with the motherboard. The DDR2 has four internal banks of memory while the DDR3 has eight. I'd avoid DDR3 in that board if it was my system. DDR3 produces lower heat than DDR2. This is what all generations have in common, but logically each new generation has been implementing changes and improvements that make them technically very different. DDR2 stands for double data rate version 2 and DDR3 stands for double data rate version 3. Distance of Notch. You can find sticks of DDR2 RAM that are 4GB, but the most common maximum is 2GB. On the DDR3, the range is 800 to 1600 Mbps. The main difference between DDR2 and DDR3 is that DDR RAM has a transfer rate of 1600 MB/s, DDR2 RAM has a transfer rate of 3200 MB/s, whereas DDR3 RAM has a transfer rate of 6400 MB/s. DDR2 speeds range between 400 MHz (DDR2-400) and 800 MHz (DDR2-800). DDR3 has a maximum of 16 GB of memory. DDR2 RAM gives 4 information exchanges for each cycle, while DDR3 expands the number to 8. In theory DDR3 is supposed to act twice as fast as DDR2 memories. DDR2 RAM provides four knowledge transfers per cycle, whereas DDR3 will increase the amount to eight. DDR3 SDRAM. DDR3, of course, was an improvement over DDR2. The other major difference between DDR2 and DDR3 is operating voltages. DDR3 consumes less power than DDR2 4. It provides further lower operating. Lower voltage means the RAM uses less power, thus putting less strain on the CPU. The clock speed of DDR3 vary from 800 MHz to 2133 MHz, where 2133 MHz is the its peak in some cases, generally clock speed is vary between 1600 to 1800 MHz. DDR3 stands for Double Data Rate Version 3. Operating voltage of DDR3 is 1.5v while DDR2 has 1.8v. DDR2 memory modules have 240 pins and are approximately 6mm in width.
