Want to know how much memory bus support

The Mother Board has not memory of its own and whatever is there it is borrowed. All the memory put together is very small and it is in the BIOS system, sufficient to run it for a few seconds. Where the memory exists is at the RAM memory. We used to have 256KBytes, then it became 512KBytes. We have to devide the modern computers in two categories, those less than 3 years old and those made this current year. Each manual will tell you how much memory the computer will support. So, those computers support up to 2GB. Now there has been an innovation with the mamory makers that they can double the size of the RAM memories. Now we are talking about 4GB. I can almost guarantee you that there is not going to be a noticeable difference in the actual speed, because we have made all the other parts to be much faster. I hope you like your answer.... Thank you for considering and the choice to use our service. My name is Constantin (arzconst is my internal nickname with Fixya.com).
