Only 2GB of 2GB memory is available, the system is not compatible with memory

        Although the minimum installation requirement of Win7 system is 1GB memory, when the system is running, this memory will be very tight! So many users will choose to buy a 1GB memory to upgrade the computer to 2GB capacity, but the system response speed does not change much. I thought that I could have more memory space to use, but after entering the system settings, I found that although the system can recognize 2GB of memory, but only 1GB is available, is the system incompatible with memory? Or what is going on?
< BR> as shown in brackets Tip:

both BiOS or testing software, you can identify the notebook installed a total of 2GB of memory, but that is not the 1GB called by the system. In general, the Win7 system will automatically recognize and use the newly upgraded memory capacity of the computer, but if we have optimized the computer's memory parameters with optimization software, it is more likely to occur when upgrading the memory again.

in the start menu search box, enter "msconfig", bring up the System Configuration window, enter the "Boot" tab, click on the "Advanced Options" button, the original is "Boot Advanced Options" limits the maximum system The memory capacity is only 1024.

uncheck the box "Maximum Memory" in front of, or enter 2048 (according to your actual memory capacity), click Apply in the maximum memory capacity of the dialog box. After

reboot the system, you will be pleasantly surprised to find the system to be "swallowed" in 1GB memory finally came out, then the system becomes available 2GB of memory.

If you find that your memory appear to be "swallowed" phenomenon, but also a display case or installed memory is not available, modifying the above method, you can make your problem is resolved, it may be Give it a try. This article is for

tend to be early adopters of computer memory upgrade from 1GB later to 2GB, before using optimization software for computer memory parameters are optimized, and later on will not change back the memory parameters. If you find that the memory capacity is being "swallowed up", or if the display memory is not available, you can look it up in this article.
