AMD Phemom 9850 only shows up with 1 core?

[TheDelChop]

Guys,

I've got an AMD Phenom 9850 Quad Core Proc running on an ASUS M4N72-E MB. I've just recently run the HWInfo utility in KDE only to notice that it only thinks I've got 1 core.

Anybody know where I can start to troubleshoot this problem?

I can update my MB, but the chip was already supported when I bought it.

Thanks,

Joe

can you post dmesg output? also which kernel are you using?

[Knurpht]

Are you looking in My Computer ( konqueror sysinfo:/ )? Please don't mess with your BIOS / Mobo right now. Konqueror sysinfo:/ should show you 4 cores.

If you're looking at matters through Yast - Hardware - hwinfo:
this should show you 4 cpu's

But, to help you we need some more information. Please copy and paste output of the commands below:

cat /etc/SuSE-release

uname -a

su -c 'hwinfo --cpu'

These commands have to be issued in a terminal (konsole) window. The third command will ask you for your root-password when executed.

Good luck

Sorry I'm sure I should have posted more information.

Yes I was looking through konqueror sysinfo:/ and it lists "AMD Phenom Quad Core Processor".

If I look through yast it lists 1 cpu.

As for my openSUSE version I'm running 11.1 (x86_64).

As for my kernel version its "Linux Home 2.6.27.25-0.1-default #1 SMP 2009-07-01 15:37:09 +0200 x86_64 x86_64 x86_64 GNU/Linux"

[Knurpht]

Could this be a hardware problem? Sure the processor shows up right with a LIVE-CD ?

What board are you using and what options in the BIOS.

Just a long shot here but I don`t suppose the cores are switching themselves
off when not needed?

I do know that this is a feature of the newer phenom II`s

Do the cores show up in another OS?

All the right settings in the BIOS?

Can you start some CPU intensive tasks and see if they switch on.

I am using an AM3 board but with only a paltry phenom II 710 and so this
does not happen.

I'm using an ASUS M4N72-E MB, this is not a Phenom II, it is a regular Phenom 9850.

I've never run CPU on another OS since I don't have one readily available, but I'll give another distro's Live CD a shot.

I will try a CPU intensive task to see if the other cores come up while that's happening.

I believe my BIOS is setup correctly, I have AHCPI disabled, and APIC disabled but most of my CPU settings are set to auto.

[TheDelChop]

Part of the reason I think this might be the OS not the hardware is the difference between the CPU info from the BIOS and the cpu info shown in /proc/cpuinfo.

The MOBO recognizes the clock is 2500MHz but /proc/cpuinfo lists it at 1300MHz. This is obviously incorrect.
