DDR3 RAM memory is an older type of computer memory for desktop computers. We carry DDR3 SDRAM and DDR3 memory modules from leading brands like Corsair, G.Skill, Crucial, GeIL, Kingston and other recognized brands. The DDR3 we have for sale is available as single memory modules and also a "kits" containing two or four modules. Adding any of these DDR3 memory modules to a desktop system will instantly boost the performance. Remember that the different types of DDR RAM cannot be mixed; DDR3 can only be added to systems and motherboards that are designed for DDR3. This memory type is available in various speeds, depending on which system they are intended for - the "mainstream" speeds are typically 1600MHz and 2400Mhz, but other speeds are available for systems that require different speeds.
