Computers with More RAM Faster if All Memory Not in Use?
Are Computers with More RAM Potentially Faster if All Memory is Not Usually in Use?
https://ci6.googleusercontent.com/pr...llyinuse00.jpg Having a computer with a hefty amount of RAM is a wonderful thing, but is it potentially faster if all of that memory is not usually in use? Today’s SuperUser Q&A post has the answers to a curious reader’s question. The Question SuperUser reader Keavon wants to know if a computer with more RAM would be faster if all of its memory was not normally in use: Suppose I have a computer with 16 GB of memory. If my computer is usually using about 4 GB of memory and never reaches 8 GB, is it any faster than a computer with only 8 GB of (the same type of) memory? Would my computer run as equally fast by removing half of the 16 GB and working with only 8 GB or memory?Would Keavon notice a difference in performance if he removed half of the RAM from his computer? The Answer SuperUser contributors Wyzard and Jason have the answer for us. First up, Wyzard: Yes, because the operating system can use the extra RAM as disk cache, which speeds up access to data on the disk. Extra RAM will not make CPU-bound computations (not involving much disk I/O) faster though.Followed by the answer from Jason: Since every operating system manages memory differently, and none was listed in the original question, I will answer in the context of Windows 7. |
