DDR3 SDRAM is a type of synchronous dynamic random-access memory (SDRAM) with a high-bandwidth interface, succeeding DDR2 and preceding DDR4 SDRAM. It was released in 2007 and is known for offering higher data transfer rates and lower voltage requirements compared to DDR2. Key data transfer rates range from 800 to 2133 MT/s, utilizing a 400–1066 MHz I/O clock with an 8-burst-deep prefetch buffer. Standard voltage is 1.5V, though the low-voltage variant, DDR3L, operates at 1.35V and is required for some newer Intel processors. DDR3 DIMMs have 240 pins and are not physically or electrically compatible with DDR2 or DDR4 memory modules due to different key notches and signaling voltages (DDR3 uses SSTL_15). It remains an affordable and available option for upgrading or maintaining legacy systems for basic computing tasks.

DDR3 SDRAM is the third generation of Double Data Rate Synchronous Dynamic Random-Access Memory, offering significant bandwidth improvements over DDR2. It is defined by JEDEC standards and covers a range of speeds and latencies. While largely superseded by DDR4 and DDR5 for modern high-performance systems, DDR3 remains relevant for budget builds and maintaining older hardware due to its affordability and availability.
