Hi,
Intel processors support multiple voltage and frequency settings. It is called DVFS technology. But I can't find information about supported frequency and voltage in follwing files:
Datasheets , Design guides , Specification updates
By the way, my processor is <!-- /* Font Definitions */ @font-face {font-family:宋体; panose-1:2 1 6 0 3 1 1 1 1 1; mso-font-alt:SimSun; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 135135232 16 0 262145 0;} @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-1610611985 1107304683 0 0 159 0;} @font-face {font-family:"\@宋体"; panose-1:2 1 6 0 3 1 1 1 1 1; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 135135232 16 0 262145 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; margin-bottom:.0001pt; text-align:justify; text-justify:inter-ideograph; mso-pagination:none; font-size:10.0pt; font-family:"Times New Roman","serif"; mso-fareast-font-family:宋体; mso-fareast-theme-font:minor-fareast; mso-font-kerning:1.0pt;} .MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} /* Page Definitions */ @page {mso-page-border-surround-header:no; mso-page-border-surround-footer:no;} @page Section1 {size:612.0pt 792.0pt; margin:72.0pt 90.0pt 72.0pt 90.0pt; mso-header-margin:36.0pt; mso-footer-margin:36.0pt; mso-paper-source:0;} div.Section1 {page:Section1;} -->Intel® Celeron® CPU E3200 2.4 GHz
Can you help me?

The information that you are looking for is not available easily. The thing is that processors will utilize a range of voltages (0.85V – 1.3625V) and this depends on the processor temperature, usage, core speed and features like the Enhanced Intel SpeedStep(R) Technology (EIST).

Thank you for your help.
But why some paper list some settings about voltage ,frequency and power.(matching)
for example:(about xscale processor)
Frequency fk (MHz) 150 400 600 800 1000
Voltage(V) 0.75 1.0 1.3 1.6 1.8
Powerconsump. pk (mW) 80 170 400 900 1600
How can I get similar settingsv like that?
Thank you!

No, or at least you wont get a general one as it depend on many factors like the specific motherboard design and chipset.
The information that you are looking for can only be provided by the motherboard manufacturer when using that specific processor.

Oh,my motherboard is G31_M8056_A662, cpu is intel® Celeron® CPU E3200 2.4 GHz, I will try to contact Lenovo.
If they can't give valuable information, I think intel is more familiar with its cpu.

Intel wont give you that information as it will need to be tested on your computer to measure the correct voltage and provide you with an answer.

Sorry to bother you again. I have contacted Lenovo,and they told me to get information about G31 motherboard from intel site.
I have tried all the technical files, but with no result.
BTW, I have only a power meter, which can test the whole system voltage, current ,power. But how about the processor.
How can you get it?
Thank you.

There is no way to do it directly. Intel(R) uses specialized systems to test the processors running at certain speeds and see how they work and if it gives processing errors.
It seems like the only way to know this information is that you go and change the multiplier on your system and the voltage and run a stress test for every change, this way you can get that information.
Remember to stay in the voltage ranges that where provided above.
Note that this may burn your processor and void your warranty.
