How to set CPU multiplier to 21 in the BIOS?, It just sets to 20

I'm trying to set to 21 and my fsb to 160 so I can have a CPU frequency of more than 3.2 ghz( from 2.67ghz), but multiplier in bios goes up to 20. ( my processor can be set up to 24).... How can I get it to 21???. Also how can I asynchronize my cpu ratio from my memory ratio?? Thanks

SOURCE: Mobo won't accept P4 CPU.

There are FSB settings as well as voltage settings in your bios. Go to intel website to get correct voltage and FSB for the processor you wish to choose.

You can cause SERIOUS damage to your computer if these settings are not just right.

(If you do decide to flash bios, be very careful. Make sure you download the right version or your pc will be useless).

Good luck,

Try clearing the CMOS --- the down side is your lose all your setting --- the up side is you should be
able to access your BIOS

Clear CMOS Jumper: CLR_CMOS1 ( Located near CMOS battery )
The motherboard uses CMOS RAM to store the basic hardware information (such as BIOS data,
date, time information, hardware password...etc.). Clear CMOS data is the fast way to go back to
factory default when the BIOS settings were mistakenly modified.
The steps to clear CMOS data are :
1. Turn off the computer, unplug the power cord from the power outlet.
2. Remove jumper cap from pins 2-3, put it onto pins 1-2 to short them.
This will clear CMOS data.
3. Return the setting to its original with pins 2-3 closed.
4. Plug in the power cord to your computer and turn it on.
5. Go to BIOS Setup to configure new system as described in next chapter.
Clear Jumper on pins 1 & 2

  • Disconnect the power cable before adjusting the jumper settings.
  • Do not clear the CMOS while the system is turned on.

I cant overclock my system but i go to bios now whati had to do

The BIOS. Overclocking is best done in the computer's BIOS (Basic Input/Output System or Binary Integrated Operating System). There are also some motherboards that let you do a basic increase in power by setting a jumper, but this is dangerous and you have no real stability control.

There are some software programs available which allow you to overclock inside the operating system, but the best results are achieved by changing BIOS settings. Usually you can get into your BIOS by pressing DEL (some systems may use F2, F10, or Ctrl-Enter) as soon as your computer begins the POST

(Power On Self Test - when it shows the RAM size, processor speed, etc.).

Here, you can change your FSB (front side bus), memory timings, and your CPU multiplier (also referred to as CPU Clock Ratio).

Clearing your CMOS. Sometimes, an overclock can become unstable. If this happens, or your computer will not boot, you will need to reset the BIOS back to default and start over again.

This is done by clearing the CMOS (a small piece of memory on the motherboard which stores your BIOS configuration, and is powered by a small battery). Some newer motherboards will bypass user settings in the CMOS if the computer fails POST (often caused by a faulty overclock). However, most motherboards require a manual clear.

This can be done in two ways, depending on your motherboard. The first way is by changing the position of the clear CMOS jumper on your motherboard, waiting a few minutes, then repositioning the jumper to its original place.

The CMOS Jumper

The second way, if your motherboard doesn't have this jumper, consists of unplugging your computer, removing the little CMOS battery, then pressing the power button (your capacitors will discharge), and waiting a couple of minutes.

Then you have to refit the battery and plug in your computer. Once your CMOS is cleared, all BIOS settings are reset back to default and you'll have to start the overclocking process all over again. Just so you know, this step is only necessary if your overclock becomes unstable.

Locked or Unlocked. The first thing to know when you start the process of overclocking, is whether your processor is multiplier locked or unlocked.

To check whether your CPU is locked, lower your multiplier via the BIOS one step, for example from 11 to 10.5. Save and exit your BIOS and your computer will restart.

If your computer posts again and shows the new CPU speed, it means your CPU is unlocked. However, if your computer failed to post (screen remains black) or no CPU speed change is present, this means your multiplier is locked

Multiplier Unlocked Processors. Usually, your max overclock is limited by your memory, or RAM. A good starting place is to find the top memory bus speed in which your memory can handle while keeping it in sync with the FSB. To check this, lower your CPU multiplier some steps (from 11 to 9, for example) and increase your FSB a few notches (e.g.: 200 MHz to 205 MHz).

After this, save and exit your BIOS. There are a few ways to test for stability.

If you make it into Windows, that is a good start. You can try running a few CPU / RAM intensive programs to stress these components. Some good examples are SiSoft Sandra, Prime95, Orthos, 3DMark 2006 and Folding@Home.

You may also choose to run a program outside of Windows, such as Memtest. Load a copy of Memtest onto a bootable floppy, then insert the disk after you have exited the BIOS.

Continue to increase your FSB until Memtest starts reporting errors. When this happens, you can try to increase the voltage supplied to your memory.

Do note that increasing voltages may shorten the life span of your memory. Also, another option is to loosen the timings on the memory (more on this a bit later). The previous FSB setting before the error will be your max FSB. Your max FSB will fully depend on what memory you have installed. Quality, name-brand memory will work best for overclocking.

Now that you know your max FSB, you'll figure out your max multiplier. Keeping your FSB @ stock, you raise your multiplier one step at a time. Each time you restart, check for system stability. As mentioned above, one good way to do this is by running Prime95.

If it doesn't post (reread the section about clearing the CMOS), or Prime 95 fails, you can try to raise the core voltage a bit. Increasing it may or may not increase stability. On the other hand, the temperature will also be increased. If you are going to increase the core voltage, you should keep an eye on temperatures, at least for a few minutes.

Also note that increasing voltages may shorten the life span of your CPU, not to mention void your warranty. When your computer is no longer stable at a given multiplier setting, lower your multiplier one step and take that as your max multiplier.

Now that you have your max FSB speed and your max multiplier, you can play around and determine the best settings for your system. Do note that having a higher FSB overclock as opposed to a higher multiplier will have a greater impact on overall system performance.

hope this helps

How to tweak your computer

Step 1
Back up important files. This includes impotant datas stored on your computer
Step 2
Update the firmware of your computers BIOS. Also update or patch your OS to the lates update and even your hardware devices must be updated as well.
Step 3
Also before proceeding ,remember to get a BENCHMARK test program that will help you see the changes and also monitor the temp. of your processor after overclocking
Make sure that your BIOS is also set to shutdown once illegal voltage or temp. will be detected
Step 4
Ensure that the CPU FAN is clean and is still calibrated to the right rpm
Step 5
Power on your unit ,hit the hotkey to access setup.On the BIOS go to ADV. CHIPSET option.Then look for"clocks, "frequency/voltage control" or "voltage options." This will look unique on each brand of computer.You can overclock by modifying "CPU bus frequency" or "CPU FSB frequency." Increase this value slightly. In some cases, you will be able to increase your "CPU multiplier" through the BIOS.If your BIOS has none of these options,your motherboard is not capable of overclocking the processor.
Step 6
You can also try overclocking your MEMORY AND VIDEO speed. Some motherboards have this options on the BIOS as well
Step 7
You can consult your motherboards manual to know the operating voltage of your cpu or type in the model of the board on yahoo or google.

My external frequency is set wrong and should like to know what it is.Its an asus p4s8x-x hope you can help thank you

The Asus P4S8X-X has C.P.R.

CPU Parameter Recall

(Central Processing Unit, or Processor)

Restart the computer, and BIOS will set the CPU parameters back to the factory default settings.

Internal frequency rate times the multiplier = external frequency rate.

The Asus P4S8X-X uses Intel processors (Socket 478) that have either a 400Megahertz Front Side Bus, or a 533MHz FSB.

Since you did not state what socket 478 Intel processor you have installed, I cannot tell you what the external frequency rate is supposed to be.
(At maximum operating capacity)

Have you installed a different Processor?
Were you trying to overclock?

Hello , my server mainboards fsb is stuck at 100mhz , the board can support to 133mhz , but i cant set that speed in the bios , the settings are greyed out. my cpu supports a max speed to 1500mhz but now...

It sounds like the system is set to "auto" at the moment, OR the memory speed will not support the 133mhz fsb speed, check the RAM and see what the speed rating is. Leave the CPU multiplier alone, that may well damage the cpu.

My processor is rated at 3000 but is only running

What you are trying to do is called overclocking, and there are some excellent guides for that on the internet, like here:
I suggest you read this before proceeding the overclocking.
You can open the BIOS (press a key like F1, F2, F8 or del during startup). Somewhere there will be a menu with options for voltages and frequencies (units in V and MHz)
As you have read, processor speed depends on the multiplier and front side bus speed: CPU Multiplier x FSB = CPU frequency.
Right now, your frequency is 2200 MHz (presumably 11 x 200)
To get it to 3000 MHz (3GHz), you either have to raise the option called FSB in the BIOS to 270 (270 x 11 = 2970), or increase the multiplier to 15 (200 x 15 = 3000). Before you do so, write both the values down, so that you can reset to them, in case things go wrong.
I sugest first trying to raise the multiplier from 11 to 15. It may however, be locked at 11. If you can get it to 15, you're done, your CPU is now running at 3 GHz.
If not, you'll have to go through some more trouble.

First, you'll need to find your memory (or RAM, or DDR) multiplier and frequency, in the same menu as the FSB and CPU multiplier. Write them down as well.
As you have also read, increasing the FSB will make your CPU and memory go faster. This may however, be too much for the RAM to handle.
With the FSB frequency and multiplier, you can calculate the frequency of your RAM just as with the processor.
You will now have to change FSB from 200 to 270, so you'll also have to calculate a new RAM multiplier, if you want the RAM to run at the same speed.
For example, your RAM frequency can be 200 (FSB) x 2 (multiplier) = 400. If you then increase FSB to 270, your RAM will run at 300 x 2 = 600. You will have to lower the multiplier to get as close to 400 as you can get, and preferably lower, if 400 cannot be achieved.
Having done this, you can slowly start to increase FSB, I would suggest by 10 at a time. As soon as the PC has trouble starting, in the BIOS, increase the CPU voltage by one step, until it runs stable again. However, as your CPU is rated at 3GHz, you shouldn't have any trouble with this,and should not have to increase voltages.

If you encounter any probems, let me know!

2600+ with ASUS MB A7V266-E/AA

Here is the CPU Support list from Asus Support, for the Asus A7V266-E,

Scroll down the list. 34th one down, that is listed.

1.Did you get the Athlon XP 2600+ that has a 266MegaHertz, (MHz), Front Side Bus? (FSB)
The AXDA2600DKV3C?

There is an Athlon XP 2600+ that has a 266MHz FSB, and one that has an FSB of 333MHz. <-This one Won't work.
Model number ->AXDA2600DKV3D will Not work.
Both are Thoroughbred A/B Core models.

The AXDA2600DKV3C has a 12.5x multiplier.
Your 1900+ has a 12x multiplier. (AXDA1900DUT3C) They both have an FSB of 133MHz. (Shown as 266MHz because AMD processors are 'Double-Pumped')

A.The AXDC2600DKV3C will not work. It has a 16x multiplier. (Thorton Core)
B.The AXDC2600DKV3D will not work. It has a 333MHz FSB. (Thorton Core)
C.The AXDA2600DKV4C will not work. It has a 15x mulitplier. (Barton Core)
D.The AXDA2600DKV4D will not work. It has a 333MHz FSB. (Barton Core)
E.The AXDA2600DKV4E will not work. It has a 400MHz FSB. (Barton Core)

2.Are the jumper blocks -> CPU RATIO, and SYSCLK, still set in the Jumper Free Mode?

By the factory default settings these jumper blocks, (DIP switches), should already be set to Jumper Free Mode.
The white DIP switches should be in the OFF position. (The white switches will be DOWN, towards the numbers on the jumper block CPU RATIO. They will be UP, away from the numbers, on the jumper block SYSCLK))

The CPU RATIO jumper block is right above the processor. It is a blue rectangular block.
The SYSCLK jumper block is down the motherboard, right below the AGP graphics card expansion slot. (And above the first PCI expansion slot)

If those two jumper blocks are not set to Jumper Free Mode, set the DIP switches in the jumper blocks to this setting.

Now go into BIOS Setup. In the main menu use the Right Side Arrow key on your keyboard, and highlight Advanced.
If -> CPU Speed is set to Auto, you won't have access to set your CPU parameters. If it is set to Manual, you will see them. If it's set to Manual, write down the headings, (CPU:System Frequency Multiple, System/PCI Frequency (MHz), and so on) Write down the numbers to the right of these headings. If something goes wrong, you can go back into BIOS Setup, and change them back.

1.CPU:System Frequency Multiple should be
2.System/PCI Frequency (MHz) should be
3.System/DRAM Frequency Ratio should be
4.CPU Vcore should be (1.750)
5.CPU Level 1 cache, and Level 2 cache should be (Enabled)
6.CPU Level 2 cache ECC Check should be (Disabled)
7.BIOS Update should be (Enabled)
8.PS/2 Mouse Function Control (Auto)
9.USB Legacy Support (Auto)
10.OS/2 Onboard Memory >64M (Disabled)

Leave the rest alone.

The AXDA2600DKV3C uses 1.65 volts, has a 12.5 clock multiplier, and a 266MHz FSB. (You will see 133MHz, and set all your settings to 133MHz. AMD processors are 'Double-Pumped'. Intel processors are 'Quad-Pumped')

RAM not running at full speed

Go to page 33 in your manual, see DRAM Clock/Drive Control & press enter. You can tweak your memory to run faster however your manual suggest not too. Hate to see you burn it up. As you will see everything is set to Auto:
Max Memclock (Mhz) [Auto]
1T/2T Memory Timing [Auto]
CAS# latency (Tcl) [Auto]
When DDR Timing Setting by is set to Manual, use this item to set the DRAM frequency. Would be nice to have a side panel fan blowing on your memory.

Cervical Cushion- Pillows for Neck Pain Are you a very sedentary person? Do you have a classic office job and are 8 hours or more sitting in front of a computer? Then you most likely suffer from cervical pain. Cervical pain means having severe pain in the neck area because of an incorrect position of our cervix for quite some time. The cervical block or its numbness is due to the unnatural compression of the vertebrae. In this guide you will find all information about cervical pain, how to prevent them and how to cure them, but above all you will learn how to choose your cervical cushion that will help you lessen the pain or make it disappear completely. In the following table you will find some models of cervical pillows that can be found on the market, along with some of the major features that distinguish them. How to Choose a Cervical Cushion Since on the market you can find a great multitude of cervical pillow models, choose the most suitable one and certainly not a small business. First of all, choosing the most appropriate one is to understand what pathology you are suffering from. Although we often call it neck pain, cervical is not always the same in all cases. In this regard, it is understood that not everyone can use the same cushion. There are cases where the patient needs a more flexible pillow, others where there is a need for stiffer material, so before buying your new cervical cushion it would be interesting to consult your trusted physician, who can visit you and decide for you what is best suited to your pathology. Another factor could concern the price, but being in the medical field I recommend closing an eye on this item, ten euros more or less are nothing when it comes to health. Moreover, the price is directly proportional to the quality of the material used and of course there are materials that cost more than others. So as you see there are several factors to consider. Take care of all the advice you'll find on these pages and you too will be able to make the right choice. What is cervical pain and remedies? The area of ??the cervical vertebrae is that portion of our body that accuses so-called cervical pain when our neck or our head is in an incorrect position for several hours. This area is very important for our health and our well-being. In practice it connects our body and especially the spine to the head, with all the nerve endings that pass right in this particular area and very sensitive. When this area is subjected to a continuous stress, we do not only pain neck pain, but we also compromise the proper functioning of the head movement. Very often the pain becomes so strong that besides affecting the neck, it moves to the upper shoulders and joints, causing the famous head turns and also nausea. In the most severe cases a capatina is recommended by your doctor. Among the various factors that can trigger these severe pains are incorrect posture or an improper pillow. At the origin of this evil, however, there are also muscle contractions, trauma and stress. For this reason, the cervical pillow was born, which relieves the pain and allows the neck to be in the correct position. Structure, shape and material are designed to fit perfectly to the shape of the neck, sustaining it and giving it relief.
