I am not saying how to support more than 4G of RAM nonsense, the Earth people know installed on the 2003SP2 Enterprise version can support. Many people plugged in 8G memory but found that the system no matter how many programs to run the physical memory to use 3G or so, the machine with the time running the program more and more slowly, hard drive lights have been flashing.
I was also baffled at first, thinking that the 2003 system is like this, but also try to use Supercach, RAMDisk these software solutions, but these software has a very big disadvantage: will not release the allocated physical memory (this is also waste AH), occupy resources often jammed computer. In fact, the above problems are caused by virtual memory settings, I began to think of virtual memory, but the set did not run high load, feeling settings before and after no difference and missed the opportunity to detour.
How to set up virtual memory, according to the old online method: physical memory 1.5-twice times, faint, 8G physical memory is not more than 12G? 2003 system Defaults This is how you set up 8G virtual memory, and it's not a priority to use physical memory, so no matter how many programs you run use virtual memory. Tell me about me. The method of setting up virtual memory, first run all the programs that you want to run at the same time, see the digital xxxxxx/******* in the lower right corner of the task Manager. Here, write down xxxxxx this number, Then add 1.5 or 2GB to subtract the physical memory you plug in to set the virtual memory size, if xxxxxx plus 2GB less than the physical memory, then you can disable virtual memory. Why to 2G more, I believe many friends also know that this is to leave room to prevent sometimes memory has not been released or other principles caused by insufficient memory.
Say my own effect: set up before, open a number of large programs to occupy only about 3G of physical memory, the program response is very slow, the program window switch often appear suspended animation, hard drive lights are often long bright. After setting, the program responds quickly, the window toggles the brush, and the hard drive also flashes less.
PS: Now I also use 2008r2, there is no this problem, a new generation of systems to make full use of hardware, the priority to use physical memory. But 2003 program compatibility is very good, is the version of XP Jack.
For example, the above diagram is an example: The total memory is 8G (7994M), actually opened the usual in the use of large software, the utilization rate of 7175M, is 7G,
According to the above calculation method: 7g+2g=9g, greater than the physical memory 8G, so to set virtual memory. 9g-8g=1g so actually the virtual memory setting 1-2g is completely enough.
