How does b85btc set up display and memory
as long as you are 18 to 55 years old, bring your ID card and go directly
after filling in the form, take a little blood sample and check the blood type, hemoglobin, transaminase and hepatitis B. if it is qualified, you can donate blood.
The size of the integrated display memory can be adjusted in the BIOS. The specific operation method is as follows:
1. Press del to enter the BIOS when starting up. The adjustment position of the integrated display memory is in the chipset - North Bridge sub item
extended materials:
integrated graphics card is a special kind of graphics card
the integrated graphics card generally does not have video memory, but uses part of the main memory of the system as video memory, and the specific amount is generally adjusted automatically and dynamically according to the needs of the system. Obviously, if the use of integrated graphics card to run requires a lot of memory space, the impact on the whole system will be more obvious. In addition, the frequency of system memory is usually much lower than that of independent graphics card, so the performance of integrated graphics card is inferior to that of independent graphics card. It is not necessary to use the integrated graphics card when using the motherboard of the chipset with integrated graphics card. The motherboard can completely shield the integrated graphics card, but it is rarely done because of the cost
in addition, some integrated graphics card chipsets can also support separate graphics card slots, such as Intel's G-Series chipset, while some no longer support special graphics card slots, such as Intel's GL Series chipset. The main board integrated by the north bridge chip of the main board is called the integrated main board. The display card chip integrated by the north bridge chip is the core of the integrated graphics card, which together with the video memory constitutes the integrated graphics card
2. The size of the video memory is closely related to the memory size (except for Intel 81x and other integrated motherboards). If your memory is 256MB, it is recommended to set the video memory capacity within 64MB. If your memory is 128MB, it is recommended to set the video memory capacity within 32MB.
-
to enter the BIOS, you can press the "F7" key or the "del" key through the boot
-
switch to the chipset tab
-
enter the "North Bridge" option
-
Enter "Intel IgD configuration"
-
modify the "DVMT pre allocated" project to the required size, such as 128M or 256M
-
save and exit BIOS and restart the machine
4G of memory is not enough for the system itself, where the extra memory comes from is used by the check and display. Even if it is adjusted to 2G of memory, the check and display performance will only be lower than 512M. Once the system memory application program is tight, no matter how large the memory setting is, it will return to the system to support the normal program of the computer
therefore, you don't need to set the memory with low performance such as check and display. If you need performance, you can buy a second-hand graphics card cheaply.
The method of adjusting the memory of integrated graphics card is as follows:
1. Press del to enter the BIOS when starting up, and the adjusting position of integrated display is in the chipset Northbridge sub item

types of graphics card
1. According to independence, there can be independent graphics card and integrated graphics card. Independent graphics card is a graphics card installed in the expansion slot of motherboard, and its general performance is stronger than integrated graphics card. Integrated graphics card is integrated on the motherboard, or like Intel Core I series integrated in the CPU display chip, the general performance is not very powerful, can only meet the general application
According to the interface, there are ISA, PCI, AGP and PCI Express. Among them, ISA and PCI could not be found in the second-hand market at the end of last year. AGP has agp2x, 4x and 8x according to its transmission capacity. Similarly, PCI-E currently has 16x and 32x. AGP has been eliminated. At present, both are PCI-E 32x
3. According to brands, there are ATI and NVIDIA, and each brand has its own advantages. A card (ATI Series) is superior in color restoration; N card (NVIDIA) has an advantage in game performance. N card's CUDA is powerful in calculation and decoding, as well as the application of PhysX in physical simulation.
4. According to the purpose, there are ordinary graphics card and professional graphics card. Ordinary graphics card is generally bought in the market to watch movies and play games. Professional graphics card is used in graphics and image design,. In other words, when using design software, professional card is more concive to improving software efficiency
it will be automatically allocated
it is generally dynamic 1-2g
setting is fixed, on the contrary, it wastes
good luck
