How to view your computer's memory size, model, frequency

"Start"---"Run" type "DxDiag", and then see the third item "display", there is an "estimated total memory" is the memory size of the video card

Desktop side right → properties → settings → advanced → adapter, also can see the graphics card model and memory size

---------------------------------------------------------------

Graphics Knowledge One:

Look at the adapter first, if this item does not display the specific graphics card model and video memory information, it is recommended to upgrade the graphics driver ...

How to see the video card has three common methods!

Method One:

Right-click My Computer, left-click Properties, hardware, Device Manager.

Click the plus sign next to "show" in Device Manager to expand it to show the specific graphics card model.

Method Two:

Click "Start", "Run", enter "DxDiag" in "Run", eject the DirectX Diagnostic Tool window, click "Display" tab.

Method Three:

By installing Windows Optimizer, you can detect all of your configuration information in great detail.

Graphics Knowledge II:

First of all, brand manufacturers generally in the packaging, specifications and even the graphics card label, the use of memory type, capacity, bit width, we can easily identify at a glance.

Second, we can use hardware detection/testing software to see the video memory frequency, memory bit width, memory capacity and other details. For example, many people will use gpu-z to identify the video card memory information, in the lower part of the gpu-z will show the video card using the type of memory, capacity, bit width and memory frequency. Note, however, that for GDDR2, GDDR3, and GDDR4, the memory frequency shown in gpu-z is the actual frequency, the equivalent frequency is multiplied by 2, and the memory equivalent frequency of GDDR5 is multiplied by 4.

Now the average hardware enthusiasts do not care about its capacity, and some of the video memory 512MB price even less than 128MB price. The obvious existence does not mean everything, its frequency and transmission speed is the fundamental performance.

The main focus should be a bit wide bar, for example, said: 128MB of the display card, bit width is 128d and 512mb64b comparison, performance or bit width in 128b dominant! Because of the large size to calculate the bandwidth is big! The bandwidth is the root of the performance, can give full play to the memory, Otherwise, the large capacity of the memory can only be like the Bottle pour water (memory capacity), and was delayed stuck!

Therefore, it is recommended to buy a big mouth bottle (bit width) using 128-bit width, you can meet the current business, gaming and other aspects of performance.

And then it's DDR1DDR2DDR3. This is also the apparent speed of the table! meaning is that the channel inside the width can play the speed!

Then the speed of the display card interface on the motherboard,

Agp:

1x266mb/s

2x532mb/s

4x1g/s

8x2.1g/s

Generally speaking, X4 can be fully 3D. For the game performance is also possible! Its data transfer rate can reach 1g!

Recommendation: Need to find performance ratio, preferably using pci-e16x can reach 8g!
