I have an acer athlonx2 4400+ cpu multiplier is 11.5 and the memory clock divider is 12, so the ram is running at 192 MHz. how can I change this divider?

First, find out how many whole times 24 will go into 67
67/24 = 2 with a remainder that we don't care about. Write down 2
Next, multiply that answer (2) by 24 2 X 24=48
Subtract that 48 from 67 67-48=19
bring down next digit (8) append to the19 198
divide 24 into 198 198/24=8 Write down 8
multiply that answer by 24 8 X 24 =192
Subtract that 192 from 198 198 - 192 = 6
bring down next digit (7) append to the 6 67
divide 24 into 67 67/24 =2 Write down 2
multiply that answer by 24 2 X 24 = 48
subtract 48 from 67 27-24=19
bring down next digit (2)append to the 19 192
divide 24 into 192 192/24 = 8 Write down 8
multiply that answer by 24 24 X 8=192
subtract 192 from 192 192-192=0 You're done!
Your answer is the numbers you wrote down after the divisions = 2848

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

The original CPU was 1200 Mhz, namely 12 times the 100 Mhz "clocking" supplied by the motherboard.
The new CPU is 1.53 Mhz, namely 11.5 times a 133 Mhz clocking, if the motherboard can supply that rate of clocking.

If your motherboard can only supply 100 Mhz clocking,
then the new CPU would run at 1150 Mhz (namely its 11.5 multiplier over the 100 Mhz clocking), i.e., slower than the original CPU.

Can you try the 1.2 processor in some other motherboard?
It's possible that you "killed" it, when you removed it,
or after you removed it, by giving it a static-electricity burst.

Do you have another processor that you can try in your motherboard?

What happens if you put the 1.53 processor into the motherboard?
Does it POST (Power On Self Test) ?

Select the model motherboard you have and click on the CPU support link, it will show you a list of CPU's that are supported. You have a socket 939 board and AMD CPU's are now AM2, AM2+ and AM3 socket, which are 940 pin. It may be difficult to find a new CPU for your motherboard that is new since they have not been made in awhile.

What you are trying to do is called overclocking, and there are some excellent guides for that on the internet, like here: http://www.compunamics.com/overclocking.htm
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!

probably itz either minor case of software corruption/improper ground/cpu fan..
or major case of faulty or defective main board/ram/hdd..

..plz do check the following as in order:..
the Hardware part:..
1)see if the ram(s) is loose/faulty..open clean/remove carbon & or oxide formed on the teeth with an eraser n resit it..or replace with a standby n see..

2) 4) a) see if ur hdd is noisy or emitting any 'ticking' noise (like 'tuk tuk' or 'kirr kirr')..
b) or if the system is not supporting either the newly installed device or itz software/driver /firmware
if so, u need either a fresh os installation or ur hdd is likely to b replaced..

3)remove/clean dust neatly..dust is non-uniform in nature n may cause jam/short circuitry/excess resistance n many more..resulting an increase in heat..

4) open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink Compound" (available in local electronics chip level spare market) between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it tightly in position..

5) on main/mother board..see with a debug card for mb error..may b short..look for defective capacitors(esp above1000mfd)/mosfets..go through the mb's south bridge n the circuit lie around atx connector..the crystal clock generator (if cpu isn't heating up)....

the Software part:..
1) hv a licensed and UPDATED antivirus installed (i prefer avg/kaspersky,remember, without updation a full version antivirus is useless)..

2) download, install n run microsoft kb890830..http://www.microsoft.com/downloads/details.aspx?FamilyId=AD724AE0-E72D-4F54-9AB3-75B8EB148356&displaylang=en..

3) download n run Startup Control Panel..http://download.cnet.com/Startup-Control-Panel/3000-2094_4-10039330.html..'remove all the unnecessary startup items from here..(if u can't find what to remove, post me/us in ur comment with all the items listed in each n every tabs herein)..

4) remove all unnecessary software from add/remove programs..

5) download, install n run 'Advanced System Care Pro'..http://download.cnet.com/Advanced-SystemCare-Pro/3000-2086_4-10399324.html..

6)disable the following:..
a) 'Automatically Restart' right click on my computer->properties->advanced->startup n recovery->(uncheck on the) Automatically Restart;
b)'Error Reporting' right click on my computer->properties->advanced->error reporting->disable error reporting->(uncheck on the) 'but notify me when critical error occur'..

7) Increase the size of Virtual Memory, Initial: 1440; Maximum: 2880

if u r bot a professional, always better to seek advise from ur system admin/vendor....

Some systems have "bottlenecks," where small overclocking of a component can help realize the full potential of another component to a greater percentage than the limiting hardware is overclocked. For instance, many motherboards with AMD Athlon 64 processors limit the speed of four units of RAM to 333 MHz. However, the memory speed is computed by dividing the processor speed (which is a base number times a CPU multiplier, for instance 1.8 GHz is most likely 9x200 MHz) by a fixed integer such that, at stock speeds, the RAM would run at a clock rate near 333 MHz. Manipulating elements of how the processor speed is set (usually lowering the multiplier), one can often overclock the processor a small amount, around 100-200 MHz (less than 10%), and gain a RAM clock rate of 400 MHz (20% increase), releasing the full potential of the RAM.

AMD also produced x86 designs which competed with Intel on performance rather than price. In January 2002 the Pentium 4 gained a lead in sales and AMD marketing responded by giving their processors numeric suffixes approximating the clock rate that an AMD Thunderbird (and by inference a Pentium processor) would need to give matching performance, openly undermining the "megahertz myth".

Simply, yes you can. just open the case and put in the new boards. you can buy higher spec. memory(as long as the pins are the same number)
I.E. ddr-sdram boards will fit and as long as the speed is the same (132.8 Mhz) or higher.
I changed from 133Mhz to 333Mhz and the performance was much improved.
The PC3200 is the important bit, should be the same.
after you change the memory ,try running disc clean up in "start, all programs, accessories, disc clean up" this will also speed things up as well as de-fragmennting your drive(s)

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.
