Can a branded computer expand its memory Does memory expansion work?

This has nothing to do with whether it is a brand or not, it depends on whether the motherboard has an expansion function, and now it is generally available, and the expansion of one can add a memory, or you can sell the old one and directly replace it with a bigger one.

In general, there are two options for expanding memory... The first can be upgraded from Lenovo... Of course, the price will be a lot more expensive...

The second is to look at the memory suitable for your motherboard... Find it yourself... But a big brand like Lenovo will be invalid after you dismantle it privately...

Think carefully ... Your machine should be relatively old... At least two years.

So don't worry about the warranty... Open the case yourself first to see if there are more than the memory slots... If there's anything left, look at the brand and frequency of the original memory...

Try to buy the same parameters... lest there be compatibility problems...

Memory is definitely expandable, but graphics cards are not.

The motherboard of the branded computer has at least 2 memory slots, which will not be omitted again.

In order to facilitate future upgrades, try to choose the maximum capacity configuration.

Can the upstairs be clear?

The title is different from the description.

It is recommended that brand computers are not allowed to be disassembled during the warranty period. There will be tamper-evident markings on the chassis, otherwise it will affect the warranty.

If the warranty period is over, then it can be disassembled.

Of course, if you want to add memory to your computer, you have to see if the motherboard supports it. Generally newer motherboards can expand the memory.

Yes, but the memory should be bought according to the original model.

Yes, you have to buy the same model, if it's different, you can't use it if you want to.

Yes, find a memory of the same model, open the case, and plug it in.

Absolutely. If you buy it, you can buy 1g directly.

It can reduce the memory usage, improve the running speed, and install more software you need without worrying about insufficient memory.

The memory expansion function is that a part of the flash memory used for storage can be used as memory, so as to improve the user experience, which is easily reminiscent of Windows virtual memory technology. As for the degree of improvement,It depends on the memory expansion ability of each family,Take OPPO as an example,Reno5Support memory expansion,The expansion size can reach3G,5G,7G,And after setting,It takes effect after shutdown and restart。

Memory expansion means that the memory card that can be used by the mobile phone can expand the capacity, for example, the memory of the mobile phone itself is small and not enough, and it supports memory card expansion, which can be used to increase the space of the mobile phone. There are two types of phone memory expansion:

1. RAM is random access memory, which is the internal memory that directly exchanges data with the CPU, also called the main memory memory, which can be read and written at any time, and the speed is very fast, usually used as a temporary data storage medium for the operating system or other running programs, the content of the storage unit can be taken out or stored at will on demand, and the storage speed of access has nothing to do with the location of the storage unit.

2. ROM is called read-only memory, that is, it can only read and cannot be written at will, that is, it can only read the data inside, and can not modify and delete the data in it at will, just like the Android system cannot modify the system files before the root, and now the concept of ROM also includes the concept of can write, delete, and modify the file, especially in the Android system, so the ROM contains a part of the space occupied by the mobile phone system, and the remaining space can be used to store **, **, **, etc., and can be deleted and modified at will.

Since the portability of notebooks has been loved by more and more people, the configuration of notebooks is now more and more high-end, and the performance is becoming more and more excellent.

In order to make it easier for users to replace laptop components or upgrade hardware, the internal components are designed as detachable modules, usually with two memory modules.

slots, users can configure and assemble different levels of hardware according to their needs. So it's useful to expand the memory for your notebook. The following is the relevant information I have compiled for you for your reference!

Expanding the memory can boost your computer's hard drive.

and the capacity and speed of interaction with the CPU, which in turn achieves the improvement of computer programs.

The effect of running speed, but it can't be blindly expanded, provided that your CPU and hard disk have a high enough speed to calculate.

Recommendations for expanding memory in notebooks:

1.To expand the memory of your laptop, the premise depends on whether your system is win7 32-bit or win764-bit.

Bits up to 3G memory support No matter how many memory modules you put in, the system only recognizes 3G

There is not much limit to the memory of the bits, but I recommend 8G of RAM to be enough.

4.Go to the Internet or local computer city to buy an 8G memory module or 2 4G memory modules and open the back cover directly to install it.

Memory is one of the most important components of a computer, and it is the bridge that communicates with the CPU. The running of all programs in the computer takes place in memory, so the performance of the memory has a very large impact on the computer. Memory, also known as internal memory, is used to temporarily store computing data in the CPU and exchange data with external memory such as hard disks.

As long as the computer is running, the CPU will transfer the data that needs to be calculated to the memory for calculation, and when the operation is completed, the CPU will send the result out, and the operation of the memory also determines the stable operation of the computer.

Therefore, adding a piece of memory can improve the efficiency of system operation, increase the storage amount of memory, and enable multiple jujube programs to exchange data with the CPU at the same time.

However, it can also be seen from here that although the size of the memory can improve a certain performance, the bandwidth and frequency of the memory are also very important, and the frequency determines the speed of processing, so the size should be larger, and the higher the frequency, the better.

Let's talk about your configuration:

The CPU of this configuration is a dual-core CPU, model E1200, this CPU is already a CPU of the past, both the CPU clock and the bus are much smaller than the current one, so the processing power is limited.

Then, your graphics card, which is actually the core graphics card integrated into the CPU, is running to occupy the memory of the system, because it has no video memory of its own, so the graphics processing power of this graphics card is obviously much worse than that of a discrete graphics card.

The last is memory.,Actually, your 2G memory,Just look at the size is enough.,The frequency should be 1333,It's also enough for daily applications.,But because the graphics card has to be occupied.,The operating system also has to occupy.,So there's very little memory left for other programs.,So the operation of other programs is inefficient.。

It is suggested that if you want to upgrade the configuration, you can add another memory that is the same as your current memory to form a dual-channel 4G memory. Then, add a discrete graphics card, and you can improve the performance of your system a lot.
