Question about AMD PHENOM II X4 Quad Core 940,3.0GHz Boxed Processor

1 Answer

My computer is only using 1 core out of 4 cores. The Device Manager shows all 4 cores, while going into task manager and msconfig only shows me having 1 core? I've updated to the newest bios and still nothing happens. I can't figure out what's going on. :( INFORMATION I'm not using the processor below, I'm using quad core, 3.2 GHz 995 black edition. I only chose that one because the website would not allow me to proceed further on.

It all depends on the OS being used - earlier versions (Win 98, Me) could only work with single core CPUs. The latest Win7 is fine with multi-cored CPU's, BUT peripherals that are older than about a year may not have drivers for it.

Try using "Speccy" it will also show all of the information about your PC spec. You may not have the CPU you believe you have.

CPU = 1 processors detected. Cores per processor = 2 Genuine Intel(R) CPU T2060@60GHZ 2639 system RAM passed. 1024k Cache SRAM passed. system BIOS shadowed video BIOS shadowed


if you are referring to the detected processor in the task manager, open task manager and click the VIEW menu, then select One Graph Per Processor. Another thing to do is to go to START, then click RUN, type MSCONFIG and click OK. Once you have the MS CONFIG window up, click the BOOT tab, click ADVANCED OPIONS. From there, select/check the Number Of Processors box, then select 2. Click OK, then APPLY/OK. Restart the computer and confirm if that resolved the issue. Hope this works. Feel free to rate how useful the info is.

Dual core issue


If you are able to start the application, press control+alt+delete to bring up the task manager window. Find the application in task manager, right click on it, and left click "Set Affinity". Now, remove one of the checks so that the process is only allowed to run on one processor core.

I just bought a Sony Vaio at best buy and the ''geek squad'' wanted $40 to ''activate'' the second processor that supposedly doens't come active, they also were bragging that they would optimize the system...


They said what? Sounds like,
"Come sit beside me for a while, said the Spider to the Fly".

They're full of beans. Only if you have a computer that has TWO separate processors, that are in two processor sockets, is this done.

Your Sony laptop, has a processor made up of a single die chip, with two processor cores on it.

Dual core processors have their two processor cores activated all the time.
It is only if the second processor core is needed, that it will run.

The second processor core will operate if:

1.If more than one thread requires using both processor cores.
2.If an intense game requires both processor cores to operate.
3.If opening multiple programs, or applications, both processor cores will operate.
4.Using a 3D program that requires a lot of processor power.

To what extent, or percentage, that the second processor core operates at, is up to the task that is required of it.

It's like having a fuel dragster to just go down to the store, and buy bread. You would idle down to the store.
[One processor core operating]

Have to get down to the end of the dragstrip F-A-S-T?
Then you open the engine wide open.
[Two processor cores operating at 100%]

1.While you're on the internet, press the CTRL, ALT, and Delete keys, At The Same Time, to bring up the Task Manager. Now click on the Performance tab.

View CPU Usage.

2.Now open an intense program. (Such as an intense game for example)
Press CTRL, ALT and Delete keys at the same time, to bring up Task Manager. Click on the Performance tab.
Again, view CPU Usage.
Both processor cores are operating at 80% to 100%.

Optimize your computer system? What 'secret' do they supposedly possess?
NONE!

1.Keep your Start-Up menu down to a minimum. Only have the programs that need to start, when the computer starts. Activate the other programs manually, as you need them.

2.Keep your registry clean. I recommend using a registry cleaner on a regular basis. I use CCleaner. This registry cleaner is free, and works better than paid for versions. If it was not free, I would not recommend it here. That would be advertising.

3.Delete programs that you hardly use. Applications also. (DO NOT delete Windows programs, just programs you have downloaded, or manually installed yourself)

4.Keep your harddrive storage space to less than 50 percent full. Once a harddrive fills past this point, the computer starts slowing down.

Use external storage for more space. (External harddrive, and USB flashdrive for two examples)

As you can see, Numbers 1, and 3 above, may not apply to you at the moment. You indicate that you just bought the Sony laptop. Therefore you may not have installed anything yet. This info is for the future.

Numbers 2, and 4 may apply to you now. I would use a registry cleaner from the 3rd or 4th day, if you visit a lot of websites.
I would also use an external storage device from Day 1, if I had a lot of documents, and other information to store.
(School, College, Business) Keep your harddrive as close as it is/was, to Day 1.

(MAKE a backup of your harddrives contents right now! This is your Restoration Disk should something happen to your laptop in the future)
