Why does my computer add a memory module that doesn t reflect

1. The memory needs to be combined with the same frequency. If the frequencies are different, theoretically, the high frequencies will automatically be lowered to another low frequencies to operate. But it's error-prone.

2.It is best to run it with the same frequency and brand of memory. Combinations of memory at the same frequency from different manufacturers are also prone to errors.

3.If your newly purchased memory plugs in and it doesn't respond, check to see if there is a lot of dust in the memory slot. Try again after cleaning up.

4.If it still doesn't work well after cleaning the dust, check if your motherboard supports the memory frequency you bought.

It is estimated that the memory you bought should be DDR400, and it should be no problem to use the memory alone.

Basically, it's because the memory you bought is not compatible with your motherboard, and sometimes the 512 you bought is plugged in and only shows 256. You can try to plug in 512 alone.,I don't think it's necessarily OK.,Memory external frequency or something incompatible caused.。 When you buy memory, make your motherboard model clear.

There are two reasons, one is that your memory module is not plugged in properly and is loose. (It is possible to clean your memory modules and slots with alcohol);

The second is that your slot is broken, you can check it (remove your original memory module, use your 512MB into the slot you tried, and check it).

The memory gold finger you bought (the part inserted in the memory slot) is oxidized and wiped off with a painting eraser or medical alcohol, or the dust in the memory slot is too much to clean up.

Is it memory incompatible? One of your single plug-in 512 can boot normally, but the two memories are incompatible, sell the memory of 256, and match a memory stick that is the same as your 512, forming 1G.

What do we do when we find that we have added memory to our computer but it doesn't show up? Here's how I introduced the solution to the problem that didn't show up after adding memory to your computer, welcome to read it.

Right-click on the taskbar and click "Start Task Manager" to open Performance and check whether the total amount of physical memory has increased.

If you don't add it, check my computer properties to see if the system supports it, and the 32-bit system can only recognize about 3G of memory at most, and more than 4G can only use about 3G.

Open Advanced Options under System Configuration - Boot.

When there is a problem with the memory and graphics card, it is usually a blue screen or no display. In this case, the memory and motherboard connection card slots should be loose.

The performance of the memory module is:

1. If the machine cannot be turned on, the alarm will be started immediately.

2. Less than 10 seconds after turning on, it will crash immediately and may alarm you.

3. After starting, there is no response.

4. It does not display when it is turned on or snowflakes appear on the screen.

5. The Windows system is unstable and often produces illegal errors.

6. The window registry is often corrupted for no reason, prompting the user to restore.

7. Windows often enter safe mode automatically or crash randomly.

8. When Windows starts, when loading the high-end memory file Himem Sys, the system prompts that there is a problem with some addresses.

9. An illegal error occurred while installing Windows to the system configuration. When Windows starts, the system automatically restarts a few times.

No display processing at boot:

Usually, this is due to poor contact between the memory module and the motherboard's memory slots (in the case of troubleshooting the memory itself), and simply wiping the eraser finger back and forth with the eraser will solve the problem (do not use alcohol, etc.). And this type of failure can also be caused by memory corruption or problems with the motherboard's memory slots.

This means that this note is not compatible with your computer.

A simple detection method - take off the previous sliver, install a new sliver, if it can be turned on, it means that it is compatible and can be used.

The software only looks at the information of the hardware, and does not mean that it can be used. To upgrade the notebook with dual memory, it is best to use the same model sliver, if the model is different, make sure that the frequency and voltage are the same.

Memory, also known as main memory, is a storage space that can be directly addressed by the CPU, and is made of semiconductor devices. Memory is characterized by a fast access to memory.

Memory is the main component in a computer, and it is relative to external memory. The programs we usually use, such as Windows operating system, typing software, game software, etc., are generally installed on external memory such as hard disks, but only this can not use its functions, they must be transferred to the memory to run, in order to really use its functions, we usually enter a piece of text, or play a game, in fact, are carried out in memory.

The most likely reason is that it is plugged in backwards.

A memory module is a computer component that can be addressed by the CPU and can be read and written. Memory modules used to be an extension of the main memory in the history of personal computers. With the continuous update of computer software and hardware technology, memory modules have become the whole of read and write memory.

When we talk about the size of a computer's memory (RAM), we refer to the total capacity of the memory module.

Memory modules are an essential part of a computer, and the CPU can address the memory through the data master cable. Historically, computer motherboards had main memory, and memory modules were extensions of the main memory. In the future, there will be no main memory on the motherboard of the computer, and the CPU will rely on the memory module.

All content on external memory must pass through memory in order to function.

There are many models of computer memory modules, and the compatibility of different models of memory modules is also different, so it is not just a memory module that can be used, just take DDR memory is divided into five generations, not only this, just take DDR3 memory, it is DDR3 memory, and it is also divided into two kinds of low voltage electricity and standard voltage, so you need to make the specific situation of your memory module clear.

First of all, there are different models of the computer's memory modules, and they cannot be mixed. As you said, if you can install it, the model should be the same. Then it depends on whether your computer is a 32-bit system, it supports up to 4G memory, which can be replaced with a 64-bit system.
