4G memory installation system problems for help

Use the 64-bit Vista SP1, Windows2008 is 32-bit, and it can't recognize 4G.

The 64-bit Vista is a little less compatible than the 32-bit one.

The 64-bit Vista overall performance was mediocre.

If your computer is nicely configured, then it can accommodate 64-bit Vista

However, it is recommended that you use windos7 for optimization, which is particularly good.

Windows 2008 is good.

Although it is a 32-bit system, however, it supports up to 128G memory The most important thing is to play games

Swap back to 32 for Vista or XP

server2008 does not run the application software well.

64 is vista, running 32-bit games, and the performance can be said to be almost stuck

If you want to choose one of the two, you would rather server2008 play games far better than 64-bit vista

But it's also worse than a 32-bit vista

There are not many 64-bit software nowadays, and most games cannot be run in 64-bit (except for large single-player games), so it is recommended to set the extra memory as a memory virtual disk to use.

1.First of all, you need to make sure that the memory module is not loose, and if so, you need to reinstall the memory module after first releasing the static electricity on your hand. (If it's a laptop, you'll need to remove the power supply and then replace the memory module).

2.If it's not a loose memory module, it's possible that the problem is with the software. The win7 operating system provides users with a "memory detection tool".

With this tool, it is possible to detect if there is a problem with the user's memory. As shown in the figure below (press and hold the win+r key combination, the "Run" window will pop up, enter :mdsched in it):

3.Follow the prompts and restart your computer.

Here's what it looks like, your CPU is i5-450M, if you're using DDR3-1066 memory, the maximum supported memory is only 4G, and even if you install 8G of memory, you can only use 4G,

Click to start Control Panel (view mode changed to small icon) Management Tools System Configuration Boot Advanced Options Remove the tick in front of the maximum memory and restart it to identify it.

This problem is not caused by those loose memories at all, if the memory is really loose, your display 4G. If you say that the original display is available, and later it becomes 4G, then this problem should be caused by the core graphics (integrated graphics card) on your motherboard, and the video memory is common, and the system default is to turn on this function when the memory is greater than or equal to 4G. If you want to solve this problem, you need to disable this option in Bois, but the disabling method is not the same for different machine models, it is best to ask the customer service staff for the specific disabling method, don't ban it yourself, it is more dangerous.

Another possibility is that your motherboard doesn't support 8G RAM, but since you said it could be read at first, it should be.

Is there a memory slot that is loose, hehe.

The 64-bit one only supports 4G, so let's make a new system.

Analysis problem: CPU E5504 dual-core memory 8G 64 for the operating system. Depending on your situation, this configuration has 2G of RAM.

Analysis 1: Whether the memory module is one or two.

Analysis 2: The computer system is win7, vista or windows64-bit.

Analysis 3: The 32-bit operating system can only be recognized, and the system is a win7 32-bit system, because the maximum memory it can support is 2 to the 32nd power = 4294967296 (bit) = 4 (GB) or so. Your memory can only support up to 4GB of memory, so it can only detect about 4GB of available memory regardless of your memory size greater than 4G.

If your Win7 system is 64-bit, then it is different, it can support more than 100 million GB of memory. So when your memory is more than 4G, you can only install it as a Win7 64-bit system to fully use the computer memory.

Solution 1: The 32-bit operating system can only be recognized, so it is useless for you to install 8G. Unless you use a win7 64-bit system or a win732-bit system to patch the memory.

In 32-bit systems, only Windows 2000 Server, Windows Server 2003, and Windows Server 2008 support more than 4GB of memory, and nothing else is supported. Make sure the computer is 32-bit.

Solution 2: Normal 64-bit can fully identify 8G memory, memory module compatibility problems, one or two. One suggestion is for unified memory.

Summary: The main reason should be the system problem, the 64-bit and 32-bit reasons. You can redo the system and choose win7 64-bit. You should be in the Lenovo series when you order the computer. Ask about after-sales.

Is there 4G RAM installed on the memory slot of CPU2? Just install it all into the slot of CPU1.

What model of motherboard do you have? Does the motherboard support 8G RAM?

What system you are very old, the platform is estimated to be a little old.
