Can't seem to unlock cores...

Hi, I have a PC with a Biostar MB with an AMD Phenom II x4 965 CPU

Biostar TA785GE 128M
http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=455

When the computer boots up, at the point where the motherboard's boot screen appears and you can hit DEL to go into the BIOS....
It says "Press F3 to unlock core 3"
When I do that, the next time I boot up it says "Press F4 to unlock core 4"
When I do that... the next time I boot up it says "Press F3 to unlock core 3" again.

I don't understand why this happens, (it happened with my previous CPU also but I didn't care at the time).

I've looked in the MB manual and I don't see any mention of a core unlocking switch or anything, and I have looked through the BIOS setup and see nothing about it either.

One thing I did notice though is that in the CPU configuration area of the setup...it says:
Physical count:1
Logical count:3

and when I have hit the F4 button on start up (to unlock core 4), the logical count shanges to 4.

I don't know what that means (cuz I'm borderline idiot). If it means all 4 cores are unlocked, then why does it mention unlocking core #3 on next bootup?

Any help is appreciated.

None of the cores should be locked at all-the phenom 965 is natively a quad core, there are no locked cores. the fact it is indicates there may be a problem-does windows show all four cores?

Ok, thank you. I'm probably using the wrong terminology.

When the motherboard software (firmware?) was starting up it was telling me how to "unlock" those cores.
I'm a newb at a lot of this CPU/MB stuff...so I just went with it.

As far as the 4 cores being "unlocked" on the 965 (black edition) I just assumed that was a different sort of "unlock"... again, only because on boot-up I was being told how to unlock them.

As far as Windows showing 4 cores... to be honest I am not sure where to check that.?!

I will look around...

Thank you for the help.

EDIT: I just Googled and found this CPU-Z utility and installed it. It shows 3 cores. When I get home from work I will run thru the boot-up again and make sure I have selected all 4 and see what it says.
Is there a way IN Windows to tell how many cores ?
Thanks again.

right click my computer in the windows start up menu, click properties, on the left hand side of the window that pops up there should be an option called "device manager" click that, it will bring up a list of all the hardware on your computer. Click on processors, it should show (4) four seperate processors (should say AMD phenon II 965) if there is only 3, then windows is not recognizing all four. Though, chances are if CPU-Z is only showing three, then there is a problem. There are no cores to unlock on that motherboard. Question, did you update your BIOS before updating your CPU? What BIOS version are you running (should tell you on post, right after the computer turns on, should say BIOS version x.xx if not it normally says somewhere on the BIOS screen if you enter it.

Ok, on boot-up it mentioned hitting F4 to unlock the 4th core, so I did that.
Now CPU-Z and Windows device manager both show 4 cores.

I appreciate the help, and finding out that all cores are working. And yes BIOS is updated.

It was just puzzling to have that option to open the 3rd core every time I boot up, even though all 4 cores are working... and now, thanks to you, found in Windows.

Again, thank you, as always this place is a ton of help.

it was probably a glitch in the BIOS, if choosing unlocking the core worked, then I would leave it alone. Glad you got it figured out..
