Stands for “Double Data Rate3”, form three, DDR3 may be the heir of DDR and DDR2 memory and it is a kind of storage (Memory) to get a computer.

DDR3 has bus clock rate of 400 MHz as much as 1066 MHz, and memory chips array in dimensions from 1 GB to 24 GB. DDR 3 memory chips are almost 30% more effective in energy use than its predecessor, getting a 1.5V supply voltage (DDR2 – 1.8V).

The DDR3 standard permits DRAM chip capacities of up to 8 gibibits, and up to 4 ranks of 64 bits each for a total maximum of 16 GiB per DDR3 DIMM. Because of a hardware limitation not fixed until Ivy Bridge-E in 2013, most older Intel CPUs only support up to 4 gibibit chips for 8 GiB DIMMs (Intel’s Core 2 DDR3 chipsets only support up to 2 gibibits). All AMD CPUs correctly support the full spec for 16GiB DDR3 DIMMs.
