Just like AMI Bios, press the "Del" key to enter the Bios setup menu when booting again (some press the F 1 key), as shown in the following figure:
After entering, you will see the following menu. There may be some differences, but they are basically the same, with different names, but the functions are basically the same!
You can use the direction keys to move the cursor, press Enter to confirm, press ESC to return, use PageUp, PageDown and number keys to adjust the settings, and press F 10 in any setting menu to exit the saved settings, similar to AMI Bios settings! Then enter the settings!
Me. Soft menu setting (soft overclocking setting)
In fact, this soft menu setting is a unique technology to upgrade the motherboard, which provides a wealth of CPU external frequency, frequency doubling adjustment (which requires CPU support), AGP/PCI bus frequency and CPU/ memory /AGP voltage adjustment frequency and so on. This project is equivalent to "frequency/voltage control" in some motherboards.
The front is some basic information of CPU, and the following are the main options of CPU overclocking!
1.CPU running speed (CPU external frequency setting):
This item displays the running speed of the processor according to the type and speed of the processor you are using. You can manually enter its running speed by selecting the [User Defined] option. As shown in the figure:
Ok, I'll let go of the Bios setup boot when I arrive. Before teaching you overclocking, let me explain to you what overclocking is and the principle of overclocking, so that you can better enter the next step of Bios setting overclocking!
CPU overclocking, its main purpose is to improve the working frequency of CPU, that is, the main frequency of CPU. The main frequency of CPU is the product of external frequency (FSB) and frequency multiplication factor. For example, the external frequency of a CPU is 200MHz, and the frequency doubling is 10. It can be calculated that its main frequency = external frequency× frequency doubling = =200MHz× 10 = 2000MHz, that is, 2.0GHz.
Improving the main frequency of CPU can be achieved by changing the frequency doubling or external frequency of CPU. However, if you use IntelCPU, you can ignore the frequency doubling as much as possible, because Intel CPU adopts special manufacturing technology to prevent the modification of frequency doubling. However, some of Intel's engineering samples are not locked in the frequency doubling, and AMD's CPU can modify the frequency doubling. Although increasing the external frequency or frequency doubling of the CPU can make the CPU reach the same frequency, for example, a 2.0GHz CPU uses 200 * 10 = 2.0, we can increase the frequency doubling to 20 and reduce the FSB to 100MHz, or we can increase the FSB to 250 and reduce the frequency doubling to 8. Both methods can make the main frequency reach 2.0G, but the performance is different. Because the external frequency (FSB) is the channel used by the system to communicate with the processor, it should be improved as much as possible. Therefore, if FSB is reduced to 100MHz and the frequency multiplier is increased to 20, there will still be a clock frequency of 2.0GHz, but the communication between the rest of the system and the processor will be much slower than before, resulting in system performance loss. So, if the user's CPU can reduce the frequency doubling, try it!
The speed of external frequency is usually closely related to the speed of front-end bus and memory. So when you increase the CPU external frequency, the performance of CPU, system and memory will also improve, which is why Dier likes overclocking.
Ok, let's get down to business and continue Bios setup. After you select the "Use Defined" option in "CPU Running Speed", you will see that the previously unavailable CPU options can now be set!
1. external clock (CPU/AGP/PCI)
This is an external frequency adjustment setting option. Manually enter the external frequency value of CPU to be set. Here, the range of input values is allowed to be between 100-4 12, and linear overclocking is performed with the frequency increment of 1MHz to maximize the potential of CPU. Generally speaking, it is normal that the external frequency of CPU is around 100 to 250, and generally it will not exceed 300MHz, so users should never adjust the external frequency to the highest at one time. In principle, the CPU overclocked for the first time does not know how high the external frequency the CPU can work at, so it can slowly test and set the value of the external frequency by increasing it in steps of three to five megahertz. Here, for demonstration, the external frequency is directly set to 65438+.
If the CPU's frequency multiplication is not locked, there will be a frequency multiplication factor option under Ext. Clock (CPU/AGP/PCI) menu. This option selects the frequency doubling of the CPU.
2. Estimated new CPU clock:
This item displays the sum of the frequencies of the first two items [Ext. clock] and [multiplier].
3.N/B with CPU components:
This section can set the front-end bus allocated to MCH (Memory Controller). Options are: [PSB400], [PSB533], [PSB800] and [by CPU]. The default value is by CPU].
To manually configure this section:
If the CPU frequency is 100MHz FSB, you can choose [PSB400].
If the CPU frequency is 133MHz FSB, you can choose [PSB533].
You can select [PSB800] if the CPU frequency is 200MHz.
4.DRAM ratio (CPU:DRAM):
This part can determine the frequency ratio of CPU and DRAM.
Having said that, I have to explain the relationship between CPU and memory. The working frequency of the memory is determined by the external frequency (FSB), so when we overclock the CPU, we will also increase the operating frequency of the memory and set the ratio of the external frequency to the memory bus frequency. If DDR333 memory is used, its standard working frequency can reach 166MHz. Since we just set the external frequency to 133MHz, we can select "4:5" here to make the memory run at the highest frequency.
5. Fixed AGP/PCI frequency:
This item can be used to determine the frequency of AGP/PCI bus. This option allows you to keep the AGP/PCI frequency at a fixed frequency to improve the stability of the system.
6.CPU power supply:
This option allows the user to switch between a preset voltage value of the processor and a user-defined voltage value. Please don't change this preset voltage value at will unless you have some adjustment experience. After selecting the User Defined option, CPU Core Voltage can select the voltage used by the CPU core, which allows you to manually select the core voltage value of the processor. As shown in the figure:
Let's briefly introduce the core voltage of CPU. The rated core working voltage of P4 CPU is1.5v. Generally, the voltage not exceeding 1.65V is safe. Of course, overclocking to increase the voltage is to add as little voltage as possible under the premise of ensuring stable operation, that is, to control the temperature of CPU as low as possible from the aspect of heat dissipation. The voltage can also be gradually tried to increase bit by bit, and there is no need to rush to reach the designated position in one step. Let's try 1.55V here. Please note that the voltage exceeding 1.70V is dangerous for P4 of Beimu Core, which may burn out the CPU, so the voltage should not be too high!
7.DDR SDRAM voltage:
This part can select the working voltage of DRAM slot.
It is to increase the voltage that supplies power to DDR memory. The default voltage of DIMM module is 2.5V. If the memory quality is poor or the memory is overclocked, the memory voltage can be appropriately increased, and the pressurization range should not exceed 0.5V as far as possible, otherwise the memory may be damaged!
Finally, you can also see the option of increasing the working voltage of AGP graphics card. If your overclocking graphics card is a standard external frequency, you can consider increasing the voltage of some AGP appropriately. The default voltage of AGP is 1.5V, as shown in the figure:
Well, having said so much about overclocking Bios settings, let's continue to explain the Bios settings of other options. Of course, there are also instructions on optimizing overclocking in the following content!
2. Standard CMOS characteristics (standard CMOS parameter setting)
There is no need to say it here! I think everyone can understand! The following is an explanation of the options in IDE Device Settings. Generally, you don't need user settings, just keep the default!
3.。 Advanced BIOS function (BIOS advanced function setting)
1. Quick POST:
When set to [Enabled], this item can speed up the POST process after the system power is turned on. BIOS will shorten or skip some check items during POST, thus speeding up the startup waiting time!
2. Hard disk startup priority:
This option allows you to select the priority of hard disk startup and press.
3. Hard disk replacement information:
When set to [Enabled], if the hard disk installed in the system changes, a prompt message will appear on the screen during the boot process of POST.
4. First boot device/second boot device/third boot device/boot other devices:
Select the devices to be booted in the first, second and third order from the items of [first boot device], [second boot device] and [third boot device]. The BIOS will start the operating system in turn according to the boot device you choose! The equipment you can choose depends on the equipment you install! As shown in the figure:
3. Advanced chipset features (chipset settings)
Chipset setting is also a key setting in Bios setting, which is explained in detail below!
1.DRAM timing is optional (memory parameter setting option):
This project will set the best timing method for the next four projects according to different memory modules. The default value is Press SPD. This default value will read the content of SPD (serial presence detection) device and set these four items according to SPD content. EEPROM (Read Only Memory) on the memory module stores important parameter information about the module, such as memory type, size, speed, voltage interface and module storage area.
2.CAS delay time:
This item can control the delay time between the DRAM read instruction and the actual availability of data. A lower CAS cycle can reduce the latency of the memory and improve the working efficiency of the memory. Therefore, as long as the operating system can run stably, the CAS parameters should be reduced as much as possible to improve the running speed of the memory. On the other hand, if the memory is unstable, you can set this parameter larger to improve the stability of the memory.
3. Pre-charge delay action:
This item controls the DRAM frequency value used for DRAM parameters. Similarly, the performance of decimal values is high, but the quality of memory is also strict!
4. Delay from DRAM RAS # to CAS#:
This project can control the delay time between DRAM action instruction and read/write instruction, with 2, 3 and 4 options. The smaller the value, the better the performance.
5.DRAM RAS# precharge:
This item is used to control the waiting time of frequency waiting to start after sending precharge command to DRAM. The smaller the precharge parameter, the faster the memory read and write speed.
Generally, the above memory parameter settings cannot be moved! Let the default be enough, but overclocking players will definitely not let go of anything that can improve the performance, so if you want to improve the performance of your computer here, you must experiment slowly and choose a suitable parameter to make your computer achieve the best performance and stability!
6. Video BIOS can be cached:
Just like the caching function of the system BIOS, enabling the caching function of the mirror BIOS will allow access to the mirror BIOS, which has the caching function from C0000H to C7FFFH, if the cache controller is also enabled. The larger the cache, the faster the image performance.
7. 15m- 16m memory hole (expansion card memory allocation):
When it is set to [Enabled], the memory space of 15M- 16M will be reserved for ISA expansion cards that particularly need this setting. This will prevent the system from using more than 15 MB of memory. Please use the system defaults for this project.
8. Delay before heating:
This item can be used to select the delay time before the action of thermal equipment.
9.AGP aperture size (AGP card slot memory allocation setting):
This item can specify the system memory size used by AGP devices, which is part of the PCI memory address range and can be allocated to graphics memory space.
10. First initialize the display:
In this project, you can choose to initialize AGP or PCI slots first when the system is turned on.
[AGP]: When the system is turned on, it will initialize the AGP slot first.
[PCI slot]: When the system is turned on, the PCI slot will be initialized first.
1 1.AGP data transmission rate:
This item allows you to select the data transmission rate of AGP devices. Higher data transmission rate can provide faster and better graphics processing capability for your system. Please make sure that your graphics card supports the mode you choose. Most of the graphics cards bought now are 8X, so you can generally use the default ones.
Four. Integrated peripherals (integrated device settings)
This is an option to manage the integrated devices and ports of the computer motherboard. Because the motherboard is different, the setting of specific projects will be different, so I won't explain it in detail here, just translate it for readers to understand. Each user should set it according to the motherboard instructions when necessary, but generally speaking, these settings do not need to be adjusted!
1. IDE device on chip:
2. PCI device on chip
1. USB controller on chip:
This option turns the USB port on or off.
2.USB 2.0 controller:
This option turns USB 2 on or off. Port transfer mode.
3.USB keyboard support, through:
This option allows you to select [BIOS] to use USB keyboard in DOS environment or [OS] to use in OS environment.
4.USB mouse support through:
This option allows you to select [BIOS] to use USB mouse in DOS environment or [OS] to use in OS environment.
5. On-chip audio controller:
This option turns the integrated sound card device on or off.
3. Super equipment:
4. On-board parallel port:
5. Power management function (power management mode setting)
Hehe, there is no need to say more here! Be clear at a glance! You can set these power management options according to your own preferences! Just introduce the "CPI deferred type".
6.PNP/PCI configuration (PnP/PCI configuration settings)
1. Resource controller:
This item can configure all boot and plug-and-play compatible devices.
[Automatic]: The system will automatically detect all settings.
[Manual]: Select a specific IRQ resource in the IRQ resource menu.
2.IRQ resources:
This item can set the interrupt of the corresponding system to [PCI device] or [reserved].
3.PCI/VGA palette snooping:
This project can determine which MPEG ISA/VESA VGA card can (or cannot) work with PCI/VGA.
[Enabled]: MPEG ISA/VESA VGA card can work with PCI/VGA.
[Disabled ]: MPEG ISA/VESA VGA card cannot be used with PCI/VGA.
Seven. Computer health status (computer health status setting)
I won't say much about the specific settings here! The last article about AMI Bios setup has been explained in detail! There are some other COMS settings, so I won't go into details here. They are all very simple settings, as long as you read my Chinese explanation. (repost)
