Two types of storage are in every computer: temporary and permanent. It’s like our brain: we can remember lots of things right away or we can use long term storage. But unless you commit the information to memory, you had better write it down, which is permanent storage. In a computer, temporary storage is provided by memory, or RAM (Random Access Memory). The more RAM your computer has, the smoother it operates and the more information you can “play” with at once.
Memory is also responsible of giving extra speed to your computer and, most of all, more stability. Nowadays, almost all computers are sold with at least 8GB of DDR3, which allows users to browse fast on the Internet and easily download and upload files to the cloud.
All computers come with a ROM memory, which stands for Read-Only Memory. Like RAM, it’s another type of memory in your computer. The microprocessor can read ROM just like RAM, but unlike RAM, the contents of ROM cannot be changed. Users do not need to be worried about ROM memory at the moment of purchasing a machine because all computers come already with the necessary ROM installed.
On the other hand, the computer you buy will indeed have slots of memory. The DIMM cards plug into these slots inside the computer. Each slot is known as a bank. However, the way your memory is configured in each bank may be important. Each pair of slots has two different colors and if a dual memory channel is installed, each memory stick should be installed in different colors. For example, if the two colors are black and blue, users should not make a mistake by installing a memory by matching the colors of the slots, but one stick should go in the blue slot and another one should be used for the black slot. Moreover, if in a dual channel system the user wants to add more memory, it is advisable not to add only one stick but two: this way the computer will maintain its stability and will not flicker or be unstable.
The upgrade to more memory depends also on the software that is installed in your computer. Nor all the versions of Windows suppoprt the maximum memory allowed, which is 64 GB. Home editions of Microsoft operating systems support only 16 GB of memory because they were not designed for heavy duty computing or for a gaming experience.
Last, if a user decide to upgrade the memory, it is first better to perform a memory assessment test using a free software like Speecy to see what memory frequency the computer already has: it is not mandatory to use the same brand of memory but for an upgrade the new memory sticks that will be added need to have the same MHZ frequency of the existing sticks otherwise the computer will be unstable.
