4G memory used on win7

 

 

On Microsoft's official website shows that win7 in addition to starter version does not support 4G are supported 4G memory, (see http://msdn.microsoft.com/en-us/library/aa366778 (V = vs.85). aspx # physical_memory_limits_windows_7)

 

 

Why cannot all installed memory be used? refer to the following content.

The original PC only had 1 GB of memory. After win7100rc was installed, I wanted to increase the memory for the system. I rushed to the Computer City to cut down 1 GB of memory and immediately went home to install it;
Right-click my computer and it actually only uses 1.25 GB. Keep the memory of 0.75g, open the task manager and check

In the dark, I immediately searched for the vision and couldn't find any relevant posts. Google Baidu searched for it, but there was still no corresponding solution. I wanted to reinstall the system and thought it was too difficult to install the software (despise myself );
In this post today, http://bbs.pcbeta.com/thread-498420-1-3.htmlwe can see that some netizens are also in the same format, and they are also in the latter memory,
The wangcongzhou user said whether the maximum memory in the System Configuration was set.

In fact, this phenomenon also occurs in other win systems, but not many. Basically, this problem occurs after the memory is added, which causes the system to be unidentified and is not identified strictly,
Instead, the system retained this part, and made a name for the hardware to retain the memory. So I thought, in turn, would the system identify this part ???
To put it bluntly, immediately enter the system configuration in the search box, click memory, and click Advanced options. If the maximum memory is not checked, a value of 2048 is displayed;
Click application to confirm, restart the system, and open the task manager.

The problem has been solved. I am so happy that I am not happy with it.
However, NOD32 re-installed the virus and said that I was not logged on as a system administrator and sweated. I am not an administrator or an administrator, but I am so happy today that I will not be familiar with foreign devils,
It's just a reinstallation. Two minutes. In fact, it is also used without re-installation, that is, it is uncomfortable to jump out of a window after the boot.
Other software works normally, but I have not installed a game. If a friend playing a game encounters the same problem, don't ask me for compensation ^_^
If you have the same problem, you can try this method: type system configuration in the search box, click memory, and then click Advanced options on the memory page. The maximum memory is displayed in the pop-up window,
You can hook this up. If you use dual-core or above, select the correct value for the number of processors on the edge and check it again. I heard that this has a good effect on the system.
You can cancel this check after the instance is restarted, and the memory will not be changed back.
