8GB PC3-12800 DDR3-1600 Computer RAM
RAM, random-access memory is the computer's short-term memory that functions as a middle man between the rapid cache of the CPU and the slow storage of the hard drive. The RAM temporarily stores data that applications use as well as working parts of the operating system. It is not a permanent storage; once you shut down the computer, the short-term memory deletes. The RAM can have very long and confusing name, but actually all its parts have their meaning. Knowing them can help you to understand the RAM better and avoid making a purchase you cannot even use.RAM Capacity
The first in the row is the RAM capacity. 8GB of computer RAM should be sufficient for optimal computer operations. The needs do depend on the software you are using, and typically, the minimum as well as the recommended requirements for each program show in the software specifications. It is clever to have more RAM than the highest minimum requirement and at least as much as the highest recommended one.RAM Module Name
The memory name usually includes its projected bandwidth, which lists after PC3. 12800 refers to 12800 MB/s. This is the theoretical bandwidth and the actual numbers might slightly differ. By overclocking the CPU, it is possible to increase the RAM's bandwidth if the motherboard can handle the higher clock speed.RAM Generation
DDR stands for Double Data Rate and means that the RAM can operate two transfers per clock cycle. The number after DDR indicates its generation, so DDR3 is a third generation RAM memory. It is a successor of DDR and DDR2 and predecessor of DDR4. The different generation RAMs are not compatible because the pins are in different places, so you can only attach the type that your computer accepts.RAM Transfer Speed
The number following DDR3 refers to the RAM transfer speed, namely, the number of megatransfers per second. In this regard, the DDR3-1600 operates at 1600 MT/s. Due to the double data rate of the DDR3, this speed is twice the I/O bus clock.
