The Intel Core i3, model 2120 Microprocessor is based on the Nehalem micro-architecture,

http://en.wikipedia.org/wiki/Nehalem_%28microarchitecture%29

In the old days you had Intel Pentium 4's, that had Hyperthreading Technology. HT.

One REAL processor core operating, and one VIRTUAL processor core.
The Processor teamed up on the task at hand, using TWO processor cores.

Yes, you guessed it. TWO processors.
One REAL, one VIRTUAL.

The Nehalem micro-architecture brought HT back out.

Then the Sandy Bridge micro-architecture came out. Came out to replace the Nehalem micro-architecture,

http://en.wikipedia.org/wiki/Sandy_Bridge

The Intel Core i3 2120 is based on the 32nm Sandy Bridge, micro-architecture.

http://en.wikipedia.org/wiki/Sandy_Bridge#Desktop_platform

Now instead of having TWO processor cores, you can have FOUR with two REAL ones, and two VIRTUAL ones.

FOUR processors is what is essentially being said here.
TWO real ones, TWO virtual ones.

HOWEVER, your load that you are doing;...............

Internet searches...
Business/Office application, or program...
Game...
Video editing...........

Is not enough to use FOUR processor cores. So HT is not enabled at this time.

An aggressive, intensive new game, will click HT on; but who am I to know?

Program that you have multiple applications within it opened?
Running four or more programs?
Running two games at once?

Editing the lunar space program? lol!

Maybe THESE will kick HT on, dunno.

For additional questions please post in a Comment.

[Having HT with a processor that has TWO processor cores; is like having an alcohol burning dragster processor.

You don't use it to go to the supermarket ]

[Oh, and by the way;

NO, Intel Core i3 does NOT mean 3 processor cores.

There are TWO.

Processor Core:
Having two processor cores on ONE die chip; means there are TWO processors.
TWO processors contained in that one processor.

HT is kicked on you have FOUR processors ]

Laptop doesnt boot when multi core processing is enabled


By multi core I assume you mean when enabling all of the true processor cores. In your laptop's case it's a Dual Core processor which means there are only 2 phyiscal cores and does not contain HyperThreading Technology (HT Technology) which enables "Virtual processor cores"

Could be caused by a couple of things:

1. Your processor doesn't support multi-core processing which is a possibility given there is no HT technology for your CPU. In which case there is nothing to fix. Even though the BIOS may have this option. You can check to see if both cores are enabled when you have multi-core processing disabled; In windows right click on your taskbar and click on "Task Manager" Click on the performance tab. You will want to count the number of processor displays you see. Refer to this to see what I mean:

f6c39969-f900-4d19-bf1f-64040578cc05.jpg

b129bf4a-74da-49fb-868b-3bfda7229b97.png

The reason I have 8 CPU displays is because I'm running an i7-3820 CPU which supports HT Technology; So I have 4 physical processors cores and 4 virtual processors cores (created by HT Technology architecture)

2. You are running Core2Duo CPU with dual physical processors and have disabled 1 of the 2 cores because your laptop won't boot. This sounds more like you need to update the BIOS on the motherboard or maybe a bad CPU might be the cause as well.

Hope this helps.

Intel(R) Pentium(R) 4 CPU 2.80GHz


Hello,
The processor you are talking about is a single core processor capable of Hyper Threading. (HT).
When you allow hyperthreading in the BIOS, Windows will show 2 ghost processors in the device manager.

If you are authorized to acces the BIOS setup,,enter the setup and look for HT or hyperthreading. If you disable hyperthtreading in BIOS, you will only see one processor in device manager.
Besides, if it is a dual core the BIOS must know.

Look on the case of the computwr where the Windows logo apperas, you may find mentioned :With HT technology. It used to be a boasting/selling mantra.

Hope it helps.

How do you turn on HyperThreading on a GX260?


hyperthreading must be supported by the processor. If you don't have that capability, it won't work.

Intel P4 2.66GHz/512/533 is not working on MS9337C+.


#1. Does the CPU fan run if not then you may have a conductivity problem between fan and CPu. Did you use thermal paste or grease?

If fan is running follow directions below from my manual for MS9377C+ mainboard.

Go into the BIOS setup ,go to CPU setup, select proper voltage for you CPU. On Advanced setup page see if the hyperthreading function is revaeled. If so your CPU has this function. Set "Enabled " to test HT CPU function. If this doesn't work try "Disabling" the function. Good luck. I am about to attempt tp upgrade to a Prescott 3.0E which the box says this board supports. Sure hope so . Am running a 1.7 now.
