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,

Which is better processor between amd athelon ,sempron, turion 64

Hello rakeshmedita,

The Turion is more of a mobile processor meant for laptops since it uses less power while the athlon is for desktops and uses a bit more power. The Turion might edge out the Athlon on performance but will beat the pants off it in power consumption. The sempron is a low-cost processor meant for entry level desktops. So, to answer your question it goes Turion, Athlon, Sempron.

Hope this helps, if so please leave some positive feedback. Thanks.

Download and run the file and it will extract the contents into C:\swsetup\SP33031. Inside there will be an IDE\WinXP folder. Those would be the drivers you'd want to slip into your new disk.

Amd turion x2 rm70 vs intel core 2 duo t5750!!!!

I read this and don't believe you - yes the AMD dual core gets hot - yes AMD processor are HOT processors - is intel better - no there on par with AMD - the thu put rate is so close it doesn't matter - now vista basic is just that BASIC - if you want to bump it up - home premium 32 or 64 but ultimate 64 should get it going.
