what is the difference between DDR3 RAM and DDR2 RAM?
Posted on 2014-01-05
Hello and Good Afternoon Everyone,
Recently, I purchased an Acer Aspire 17.3" laptop with a fairly impressive hardware makeup. With respect to the hardware makeup, I did notice the 6GB of RAM to be referred to as DDR3 RAM which brings me to the point of my question. What is the difference between DDR3 RAM and DDR2 RAM? From a previously closed post, I think I understand that DDR2 RAM reads and writes data 2 times at each cycle of activity. I am still unclear with respect to exactly what that means though. Perhaps the DDR3 RAM is a newer generation of RAM as compared to DDR2 RAM, thus, making it faster because of having greater databandwidth. I assume DDR3 RAM uses a larger bus on the board for data transport too as compared to DDR2 RAM. Of course, all of these personal conclusions are based on speculation or guess work at best. With that in mind, if someone could reflect upon this question and share some insights to it, I will greatly appreciate it.
In the meantime, I will look forward to reviewing everyones feedback.
