Help: Common sense of computer hardware!!

One: Video memory is the memory that comes with the graphics card in the most easy-to-understand terms. Video memory, like system memory, is as much as possible. The larger the video memory, the more image data can be stored, and the higher the number of resolutions and colors supported.

Video memory, like motherboard memory, performs the function of storage, but it stores information about each pixel that the graphics card outputs to the display.

In addition, video memory is generally not allowed to be added.

Graphics cards are divided by interface, divided into:

PCI interface.

AGP interface.

PCI Express interface.

Two: The memory is plugged into the motherboard for data exchange, and its speed is faster than that of the hard disk.

Physical memory: This is the amount of memory configured on your machine.

Core memory: The amount of memory occupied by the kernel of the operating system.

Three: DDR memory identificationDDR memory, as the name suggests, is a double-rate synchronous dynamic random access memory, usually referred to as DDR. Because it is capable of data transmission on both the upper and lower edges of the clock trigger edge, the DDR memory has a higher data bandwidth at the same bus frequency.

DDR and SDRAM are not much different in appearance, they have the same length and the same pin distance. However, the DDR memory has 184 pins, 16 more than traditional SDRAM, and these pins mainly contain new signal interfaces such as valve control, power, clock, and ground. I myself use DDR2 667, mainly because the clock frequency is different, resulting in different bandwidth speeds.

Nowadays, there is also DDR3, but many wrenches are not compatible.

The MSI3 board you are using should not support DDR slivers.

Your board should be relatively old, and there is another problem that you haven't figured out.

Discrete graphics card refers to the fact that you buy a graphics card separately to match your machine, and the integrated graphics card comes with your motherboard, which is called an integrated graphics card! Discrete graphics cards have obvious advantages in resolution, which is why others want to buy discrete graphics cards, what kind of graphics cards your board supports, I don't know very well, now buy a general board is only a few hundred.

I please, it is difficult to get a satisfactory answer to such a question here, your question is too general, too miscellaneous, it is recommended to search for more questions in baidu that you want to know!

You can get a lot of information.

It is recommended to subscribe to the computer newspaper, which has a lot of good information!

I have software here, but unfortunately there is no place to upload it.
