Why does the system recognize 2GB of memory but only 1GB is available?

Although the minimum installation requirement for 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. 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?

Both the BIOS and the test software can recognize that the notebook has a total of 2GB of memory installed. , but 1GB of it is unable to be 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.

Enter “msconfig” in the search box of the start menu to bring up the system configuration window, go to the “boot” tab and click the “advanced option“ button, it turns out to be "advanced advanced option" In the ” limit the maximum memory capacity of the system is only 1024.

Cancel the check box in the "Maximum Memory" box, or enter 2048 (depending on your actual memory capacity) in the Maximum Memory Capacity dialog box and click Apply. After

reboot the system, you will be pleasantly surprised to find the system & ldquo; phagocytic & rdquo; 1GB of memory finally came out, then the system becomes available 2GB of memory.

Tip:

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 The memory parameter was not changed back. If you find that the memory capacity is "swallowed", or if the installation memory is not available, you can look it up in this article.
