Solved Phenom II only showing 2 processors - HELP

[glennc]

Hello to all,
I hope this is a good place to post this. Today I upgraded my X2 processor with a AMD Phenom-II X4 965. Put it in, booted, went to bios and optimized default setting and saved. Reran the system performance and it increased, but noted that the cpu gadget only showed two cores. Downloaded CPU-Z and it only shows two cores. Can anyone point me in the direction of getting this issue solved?? Thanks for any assistance.

What does it show where I have it circled?
(Start>run>msconfig - Boot, then advanced options.
If it shows 2, and the box is checked, uncheck it, and hit "ok". ( this is assuming there is not an option to choose "4" there. If there is, change it to 4, leave it checked and restart.)
Restart, check again to see if it reset and recognized the 4 cores.

Note: I have only used CPU-Z with a 2 core system, never a 4 core. I wouldn't think it would be any different, but can't be positive.

What does Device Manager show under Processors?

Hello MWRed,
I looked into the area, and it indeed was checked and set on 2. I unchecked the box, hit apply and it rebooted. Checked again and it had no number of cpu's, but a drop down included up to 4. I chose 4, hit apply and it rebooted. Seems to take a lot longer to boot??? But I reinstalled the desktop gadget and it shows 4 cpu's.
Is this correct and did I do it correctly? Many, many thanks for your help!

Howdy Sir!
The Device manager showed 4 under CPU. I think with the above info, it may be correct, finger's crossed!
Thanks for responding!

Does task manager, performance tab, show 4 CPUs?

Howdy,
It didn't before I followed the above instructions. It does now!!
Thanks for your response!

Actually that check box is to limit the number of cores. You have 1 Processor with 4 cores. Windows will by default use all cores on startup. You check that box to limit the number of cores used. The reason it originally showed 2 cores was because the box was checked with 2 in it, thus limiting the CPU to use only 2 cores.

I downloaded CPU-Z to see what my Windows7 PC with a similar processer (AMD Phenom-II X4 880) would show. It should 4 cores. Prehaps, you have other software installed that is interferring with the way CPU-Z is displaying the results. Did you try reinstalling. You may need to use something like CCleaner to remove it completely before reinstalling. Or use REGEDIT to delete it. Google search results for CPU-Z "issues", shows other users having problems with this utility. Since, both Device Manager, and Task Manager display the core results properly. I would not be to concerned with the results of CPU-Z. Try using a different utility.

Hello essenbe,
Thank you for your confirmation. I wanted to make sure! It now shows the 4 cores.
Appreciate your time!

Hello quicdraw2011,
Thanks for the information. It appears that a previous answer solved the problem, the msconfig was limiting it to to cores until I changed it. Now it shows the correct number.

I had the same problem. In my case the CPU is Phenom II x4 970 and the numbers cores shown was 3. The cause of the problem was the same. I did not have any idea why "Numbers of processor" was check-marked and entry of "3".

Thanks churin,
Didn't have a clue. When I built the machine it had the X2 in it and maybe it set itself???? When I put in the 4 core, it downloaded automatically a bunch of drivers, but never changed the cores... Live and learn!

You can leave the check box for "Number of processors" unchecked and Windows will use all cores. The reason you were limited to 2 cores was because it was checked and set at two. Its only used for trouble shooting and is normally unchecked. Your boot time might go back to normal too.

Hello pal!
The boot time is dismal. I am having a discussion on memory in another thread, I added another 4 GBs for a total of 8. It say unganged as explained in the other thread and one person say that is good, and another person says that is bad. I am leaning toward this unganged not using my memory as efficiently as it should!
Thanks weight in on the other thread, well thank ya!
