What is DDR SDRAM Memory?

DDR memory, or Double Data Rate memory, is a new high performance type of memory that runs at twice the speed of normal SDRAM. This DDR SDRAM is ideally suited to the latest high performance processors to increase overall system speed. The faster the memory, the quicker

instructions can be passed to the processor. DDR memory provides roughly a 15% boost in performance compared to regular SDRAM. With DDR memory now in the affordable price range, and motherboard manufacturers phasing out SDRAM on nearly every new board, it looks like DDR is definitely here to stay. Even corporate giant Intel dumped the once-all-mighty RAMBUS, and opted for integration of DDR support into their chipsets and motherboards, only to join forces and rise to power with the P4. Memory manufacturers are doing a good job of producing high-quality RAM for demanding systems and the ever-changing industry.

DDR SDRAM Memory | DDR2 SDRAM Memory | DDR3 SDRAM Memory

DDR3 is the next-generation, high-performance solution for CPU systems. DDR3 memory are twice as fast as today's highest speed DDR2 memory products. Select your DDR3 Memory from the following.

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
