How to Adjust the CPU Multiplier on an ASUS Motherboard

CPU or Central Processing Unit is the most important part in a computer as it carries instructions of computer programs and communicates with system components. The instructions of the programs are carried in sequence to perform basic computation on your computer.  People use computer for various purposes and sometimes it requires faster computing and calculation which completely depends on CPU and some other major components of CPU like CPU FSB and CPU Multiplier.

CPU multiplier can be termed as the speed between the CPU and computer’s front-side bus (FSB). It is also known as ‘Clock Ratio’. CPU Multiplier is the aspect by which the CPU speed is determined in MHz. It also determines the speed of your CPU processing in comparison to motherboard’s external clock speed.

For example the external clock is 133 MHz and the motherboard multiplier is set 10x, then your CPU will only be able to produce the speed of 1333 MHz.

You can adjust this value to high position or low position, which is respectively terms as ‘overclocks’ and ‘underclocks’ and completely depends on your requirement and hardware components used in your computer.

Current motherboard comes with this functionality to change the CPU multiplier and ASUS understand the use of this trick and provides this functionality in most of their motherboards.

Here are the steps to adjust the CPU Multiplier on and ASUS motherboard:


Close all the running application on your computer and turn off the computer as well. Now restart the computer and during the booting process when you see the splash screen, press ‘X’ key from keyboard to enter the setup. The ASUS motherboard setup is usually loaded by pressing “Del” or “Delete” key but you should make sure the settings as it may differ in motherboard models.

The best way to know about it is by user manual or by visiting the manufacturer’s websites. Keep note of all these information before you start the process.


Once the BIOS page is loaded, you will find various information on the BIOS setup page. It can be either a multi-page BIOS or a Single page BIOS. Now use the ‘Arrow’ key to advanced option which holds the required information.


Now try to find the option “CPU Ratio Settings” and use the “+” and “-“ keys from the keyboard to increase or decrease the value. You can increase the value in this page if you want to increase the CPU multiplier speed and the other way round.


Now save the settings in BIOS before exiting and restart the computer. This will bring the CPU multiplier speed to your desired standard.

You should have some information in hand before adjusting the CPU multiplier like the BIOS settings of particular model, FSP speed etc. This information will determine whether the CPU Clock ratio has to be increased or decreased.

How to Identify an ASUS Motherboard

It may be the case that you are upgrading the RAM on several of your organization’s older PCs and for this you need to know what type of chips each system requires. And you only have the motherboard manuals for half of the systems. What are you going to do? Time to worry? No! There are ways to find a motherboard’s manufacturer and model number without the manual, if only you know where to look for. Here I am going to suggest you ways to identify an ASUS Motherboard.

ASUSTeK is a computer corporation based in Taiwan. ASUS or ASUSTeK has become synonymous with desktop PCs. Almost one in every three desktops in the market is using an ASUS motherboard. Some manufacturers place ASUS boards into their systems without the ASUS name or make/model imprinted since the computers are made by someone else, such as Hewlett-Packard or Dell. That is the reason you have to find ways to determine whether it is  an ASUS Motherboard. But as I said before, there are still several ways to find out if the motherboard is made by ASUS. For this, you will need Internet connection, Make/Model number, FCC Number, and BIOS number/information.

The steps you need to follow are:


First of all try to locate the motherboard’s FCC or Federal Communications Commission number. It is usually comprised of three numbers, known as the Guarantee Code, followed by a dash and more numbers that are the equipment code. You will see “FCC” on the motherboard and to the right of it you may or may not notice the Grantee or Equipment Code since some computer equipment do not come with it. Once you locate the FCC number, you can go to the FCC website and can locate the manufacturer’s name based on the Grantee Code and/or equipment product code. Once the name of the manufacturer is known, you can search its Web site for information on its various motherboards and be sure whether your motherboard is ASUS.


If you could not find the FCC number or your search was inconclusive, you need to locate the motherboard’s model number. You will find it between the white PCI slots. You run the model number, such as M2N-VM or A8N32-SLI Deluxe, through the website and see if it matches the ASUS motherboard models.


If all else fails you need to obtain the motherboard manufacturer and model information from the BIOS number. There are a number of ways to obtain the BIOS number. The easiest one is as follows: hit Pause while your computer is booting up. You will notice the BIOS information displayed on the monitor. Copy down the number displayed on the screen.

If you are not able to hit the Pause key before the information disappears, turn off the computer, unplug the keyboard, and reboot the computer. If the CMOS is set to Halt On All Errors, it will freeze during the post while the BIOS information is showing on the screen. You can copy the information down and then turn off the computer and reattach the keyboard.
Once you get the BIOS number, go to websites to find helpful information on identifying motherboards from Dell, Gateway, Packard Bell, Hewlett-Packard, Compaq, and other common PC brands.
