Hello.
It is not save for your system making it work faster by overclocking it.
Some times it works fine just using the right cooling methods, but some times its leads to system freezes, crashes and even to permanent processor damage.
So i advice you to keep that in mind.

If you want to proceed anyway.
- In newest computers you will find an option to set the processor speed to automatic( system recognize the cpu speed) or manually, in the last one you hve to set the RATIO( Processor speed divided by FSB speed), this means:
- The FSB of your P3 Motherbord (133 Mhz) x 7.5(ratio)= 1Ghz
- In older motherboards the speed option is set using jumpers
configuration in the Board, inthat case you will have to use the motherboard manual( some boards have printed tables) to show you the config.
Note: if your motherboard doesn't show you the RATIO you need is because it doesn't support that speed.

Good look.

Overclock problem


Hi there, the freezing is probably caused by the north-bridge or CPU not getting enough voltage or becuase you are pushing your memory past the supported frequency, changing the FSB also changes the frequency of memory, overclocking a machine could also boost the temps past the point of conventional air cooling e.g might have to use water-cooling instead. You should be careful when you overclock your computer though, electronics are sensitive and you are going to cause permanent damage to either the board or CPU. I would rather advise you to return all values to default and continue to use the system normally, if you really need it to go faster rather go and buy a faster machine. b.t.w changing the PCI-e value will have no effect on your FSB and memory values, it could instead have an adverse effect on your graphics card if you have one installed

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,

What power supply would you recommend for a quad core processor?


Greetings - Even though the CPU is Quad core you could get by fine with a 350W PSU, unless of course you're going to have a killer juice sucking high end video card and/or are planning to overclock your CPU.

A good quality 450-500W would give you plenty of margin. More important to get quality vs rating numbers. Cheaper manufacturers tend to overstate the specs of their PSU's.

Enjoy your new CPU!

Need advice on pentium d 805 & motherboard gc11010n.86a.0311


In the BIOS (probably in advanced features or overclock menu or the sorts)
you'll need to either find the option to tune down FSB (probably around 200) or your CPU multiplier. CPU speed is FSB*multiplier, so you can yourself calculate the desired speed. If you need any help finding the BIOS menu these functions are in, I could do a little more research, but for now I'll trust you can find them yourself.

I hope this answers your question,
Yannick.

How to overclock Intel Pentium Dual Core E2140 1.6 GHz processor


The following link will tell you the very simple way to overclock this processor. Half way down the page you will find the header "OVERCLOCKING"

http://www.value-reviews.com/index.php?page=pentium-dual-core-e2140

"Since the architecture was designed for the 1066 MHz FSB, overclocking is as trivial as setting the FSB to 1066 MHz (266 MHz quad pumped).
...you instantly get a 2132 MHz CPU with little increase in temperature."

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".

Problem in overclocking my Processor.


1: You problem is your power supply, PSU. When you try to give more power to your CPU by overclocking it, it doesn't have enough wattage, or power, to get the CD drive, or your sound card to work. This is why the CD drive works again when the CPU isn't overclocked. So, in this case, to overclock your CPU, you would have to get more power to your system by getting a more powerful PSU, or one with more wattage. How much you can overclock your processor depends on a variety of different things. Your RAM, PSU, HDD, CD drive, etc. I would not go past about 3.4ghz with your processor, however, a "max overclock" is hard to determine.

2: The maximum temp for your processor is 70C, 158F. I would try to keep your temperatures under 60C to ensure your processor doesn't "die early" on you. The multiplier cannot be changed, only the FSB can be changed. You should be able to create a "profile" in bios and set it to your default so that it loads up automatically when you boot up. Make sure you find a stable configuration before you make a default profile.

I do not condone overclocking!

You can try upgrading your bios to the latest version. It may let you change the CPU settings.

http://downloadcenter.intel.com/Fi [...] &strOSs=38

Intel boards are usually "locked" (BIOS), and are difficult if not impossible to overclock.

I DO NOT CONDONE OVERCLOCKING. IT CAN RUIN,TRASH, BREAK FOREVER, MAKE CEASE TO FUNCTION, if something goes wrong, not yelling at you just want to make sure you know what you are trying toget into.
But...They do sell boards designed for that purpose, I think you can get the board you have w/CPU for under $100. Look for a different board if you are serious about it.

Overlocked my Intel Pentium 4 3.00 Ghz


You have to go into your bios and see what your front side bus and memmory speeds are. If you overclock you cpu, sometimes you need to underclock your memmory. Say step your memmory down to 333mhz and overclock your front side bus(fsb).
Normally your fsb is 200 and only increase it by mhz. Restart, go into windows. and see if it is stable.

I always use cpu-z and gpu-z to check all of my hardware settings. I use ati tool to overclock my x1950 and it is great. There really isnt any good cpu overclocking tools because its better to do it in the bios.

Do a specific search in google for your processor and overclocking.
