4GB Computer RAM
Nowadays, practically all laptops come with 4GB of DDR3 RAM as a standard component. When purchasing an upgrade in computer memory, many buyers opt for the 4GB computer RAM option, as it frequently doubles the size of their existing RAM. If you're building your own machine from scratch, it makes sense to start with at least 4GB as a minimum.
Important factors to consider when buying extra RAM include ensuring you have a 64-bit operating system in order to use all the available capacity. It's important to match the 4GB of computer RAM to actual capabilities of your system.
The quality of the DRAM chips , PC boards, and other components used on the module are critical to the overall quality of the module. Premium memory chips can cost up to 30% more than low grade chips and high quality PC boards cost about 50% more than lower quality alternatives.
Memory varies in quality from one manufacturer to another. As a rule of thumb, the bigger brand name companies are more consistent in terms of rigorous design specifications, using high quality components and implementing quality control processes for manufacturing and testing. Companies like Kingston, Corsair and Micron produce RAM packages as part of their core product range, so checking the brand can give you a certain degree of confidence in terms of quality. If buying a 4GB computer RAM upgrade for gaming purposes, something like the G.Skill Ripjaws (4GB x 2) will provide the significant boost you are looking for.
Lower quality generic modules can work fine: they may be the right solution, always depending on what you are expecting of your system, for example, in terms of running multi-media programmes simultaneously.
It is worth bearing in mind that faster responses to memory requests outweigh the benefits of simply running the memory faster. Prices have been going down, so it is not difficult to find very reasonably priced 4GB RAM upgrades. As ever, it is a question of finding a balance between expected performance and good value.
