Multi-channel modes are an effective way to increase memory bandwidth by aggregating multiple 64-bit links. Memory Configuration: Single Module Memory Type: DDR2 Package Memory Format: DIMM Package Memory Pin: 240 Memory Size: 2GB SPD Latency: 5-5-5-18 SPD Speed. This applies to AMD’s Athlon 64 X2 and Phenom series, as well as Intel’s Core 2 and Pentium families. Intel’s Core i7 processors support up to three memory channels, meaning you can use three or six memory modules operating in three-channel mode at maximum speed, while most other architectures work with two or four modules in a dual-channel configuration. Notebook memory comes on small outline DIMMs (SO-DIMMs), which are much smaller, but otherwise very similar.
PC memory is available as DDR2 or DDR3 modules, generally called Dual Inline Memory Modules (DIMMs). DDR2 is typically available at speeds up to DDR2-1066 or DDR2-1200, while DDR3 spans DDR3-800 to DDR3-2133+ speeds. DDR5, DDR5 has increased memory speeds from RAM at an incredible pace, while DDR4 speeds start at 1600 MHz and go up to 3200 MHz without overclocking, while minimum. The slowest mentioned memory is therefore referred to as DDR2-800 (400 MHz in DDR mode). DDR stands for Double Data Rate, which means that data is transferred during the rising as well as the falling edge of a clock cycle, which doubles the effective clock rate. DDR2 memory, the sequel to the current DDR spec, has been slowly building. Two types of Dynamic Random Access Memory (DRAM) technology currently dominate: DDR2 and DDR3 at speeds between 400 MHz and 1000 MHz.
