PC users that are considering upgrading to a new operating system should make sure that they have sufficient computer memory. There have been lots of changes in the amount of memory required for some of the newer systems, and a lack of sufficient memory will slow them down tremendously. Bad memory sticks can even stop a computer from running altogether.
Older model computers were only equipped with two slots for the motherboard. This did not give users the possibility to have lots of new memory in addition to what was already used. Computers that were in need of a true upgrade would have to have the old memory removed and larger amounts added. Many of the early computer memory sticks were sold in common small increments of 128, 256, and 512 RAM.
Operating systems like Windows XP were able to previously run with the bare minimum of 128, however they recently changed the amount of memory that was required for computers. This was also shown in the computer designs. The old motherboards were no longer effective. The new computers were built with four slots to make room for this change in required memory.
Computers of today can run new operating systems with 1GB of memory. Computers with 1GB will run the operating systems, but it actually takes 2GB to effectively run Windows Vista or Windows 7. Other operating systems with Open Source coding (Fedora and Ubuntu) do not take as much memory to run. That is why many people are switching to Open Source code. Older computers can effectively run these operating systems without extensive memory upgrades.
The cost of computer memory has declined greatly because so much memory is being used. A gig of memory has declined over the years because it has become the standard for upgrades. Few people purchase less than a gig of memory for computer upgrades today. It is also uncommon to purchase a computer with less than a gig of memory unless it is used. Some computers come with as much as 6GB of memory. These systems are designed this way because they are made to handle future changes.
Operating systems will continue to need more computer memory as the applications become bigger. Computer memory is one of the biggest parts of an upgrade. It can be the main asset needed to speed up a computer.
