DDR Memory Upgrades- Upgrade Memory DDR DDR2 DDR3

DDR memory technology is an evolutionary improvement of mature PC100 and PC133 SDRAM technology. DDR memory chips are produced by semiconductor manufacturers using existing wafer fabs, processes and testers resulting in lower memory chip costs. This new memory technology enables a new generation of higher performance computer systems, including desktops, workstations, servers, laptop notebooks, portables, as well as new communications products such as routers and switches. DDR memory technology is also currently widely used in high-performance graphic adapters.

You can use some of the easy tools to find your exact DDR or DDR2 Memory Upgrades for your Desktop, Laptop or Servers.
Use the Memory Selector to find compatible DDR or DDR2 Memory Upgrades, or the all new system scanner tool to scan your system to find exact matching DDR RAM. If you need more help use the Live Chat Support

DDR Memory RAM

PC2100 266Mhz DDR SODMM | PC2700 333Mhz DDR SODMM | PC3200 400Mhz DDR SODMM

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

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.
