Unfortunately the bios is locked on those machines. You could edit the bios yourself, but you need to have a deep understanding of machine code. Totally out of my expertise. However it is possible.

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.

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.

Hello, I would like to overclock my AMD mt30 CPU 1600Mhz25wattTDP 64clockspeed/power ratio to that of a SempronML37 2000Mhz35WattTDP and 57.1 clock speed/power ratio? Do I just change the voltages in...


Due to the way you stated the above John, you seem like a guy that will understand the following;

Yeah know funny thing about overclocking;

1) You may have a good Processor that came off the assembly line that day, or it may be one that just squeezed past Quality Control. Push it too much, and it will fry. Trying to make it hit 2.0GHz all day long, every day, may just push it over the limit. Sure you may have read about, or even heard of someone who did it. How long? How long did the processor last at this overclocked rate?

2) AMD's run H-O-T. Not a good idea to push a Processor with overclocking (Which makes it run MUCH hotter) in a cramped laptop environment, with a low cooling capacity anyway.

3) Ram Memory typically operates at half of the FSB Frequency Rate ('Speed'), that the Processor does. (Front Side Bus)

To overclock you can;
A) Change the Voltage
B) Change the FSB frequency rate ('speed')
C) Change the Multiplier

If you change the Front Side Bus frequency rate too far, the ram memory will not work anymore.
Won't match.

AMD Turion 64 MT-30,

http://en.wikipedia.org/wiki/List_of_AMD_Turion_microprocessors#.22Lancaster.22_.2890_nm.29

The Sempron you name is a Turion also.
Turion ML-37,

http://en.wikipedia.org/wiki/List_of_AMD_Turion_microprocessors#.22Lancaster.22_.2890_nm.29

4) You have to have a BIOS Setup Utility that will allow you to change CPU parameters.

See this article?

http://www.ehow.com/how_7335931_overclock-turion-64-compaq-nx6125.html

No mention that overclocking a Processor shortens it's 'Life Span'
No mention that if overclocked too far the Ram Memory may not work.

No mention that an AMD processor runs HOT, and if you overclock you'd better have a lot more than the factory cooling. Plus not a good thing for a laptop anyway because of a laptop's poor cooling design. (Cramped small space, small fan, inadequate cooling thermal module)

No mention that the BIOS Setup Utility in your laptop may not have a CPU Soft option, or options inside that allow you to change the Processor's parameters.

No mention that you should go slow. Change parameters in one SMALL increment, wait 24 hours, and check the system. Looks okay? Change parameters another small increment. Check during a 24 hour period. Keep going until the computer starts messing up, then go BACK to the last parameter that checked out okay

Have I dissuaded you yet?
No?
Just don't want to see someone fry their Processor, or computer.

Okay.

The Turion MT-30 has a clock multiplier of 8 times. (8x)
The Turion ML-37 has a clock multiplier of 10x.

The Turion MT-30 uses 1.35 Volts (DC)
The Turion ML-37 uses 1.35 Volts (DC)

The Turion MT-30's Front Side Bus frequency rate is 800MegaHertz
The Turion ML-37's FSB 'speed' is 800MHz.

What options in your BIOS Setup do you have for changing CPU (Processor) parameters?
State back in a Comment. (Believe top right of your page)

No options?
Then try CrystalCPUID, or ClockGen,

How to overclock my motherboard ?


there are 2 ways, overclocking using the bios to over clock the memory ( ram ) and also the processor ie changing the multipliers and other tweaks ( which should be in your motherboards manual ) that or using jumpers which are physically on the motherboard but later motherboards use the bios to tweak / over clock your computer.

Can i replace 2.8ghz(bus speed 800mhz, cash memory 1mb)in compaq evo d510 sff model methor boad intel 845g


Yes up to 3.2Ghz with same Bus speed. cache doesnt matter.

Extreme editions and some 3.2Ghz/3.4Ghz chips will need you to flash the BIOS

Let me know how you get on...
