Where is my other core?

English Hardware
#1

I began by trying to make a VM with 2 cpu’s.

I received this notification: “Your host does not have the specified number of processors. blah blah blah…”

See the screenshot:

After this I opened My Computer/System Information and checked it (this happened to me before a while back).

I forgot whether it shows 2 separate cpu’s here, but one more thing, it shows my cpu speed at 1,710.00 MHz.

Out of box this cpu is a 2.13 GHz, and I FSB clocked it to 2.28 GHz, so… why is it showing 1.7, and… how do I fix it?

Back to my original VMware Server 2 cpu dilemma. I thought I had made a vm with 2 cpu’s before, but I cant remember. To use the 2 cpu feature can you use dual cores or do you actually need 2 cpu’s?

Thanks in advance.

please check the output of
cat /proc/cpuinfo

wierd huh?

Not only what Uwe said, check your powersave settings, if on dynamic or powersave, this will reduce the cpu mhz to save power :wink:

Ugh. Which version of Opensuse are you on? In previous versions you need the SMP kernel to recognize multiple cores. Else check your BIOS.

I’m on version 11.0. I’m sure my bios is set correctly because my windows XP partition shows it.

How would I go about getting rid of my powersave options?

thanks for the ideas.

  • aluengas,

honestly, I cannot explain what’s going on. What is the output of “uname -r”?

Uwe

I re-installed. The latest kernel update caused my X server to fail. Sorry we couldn’t find a real solution. Maybe I just used the wrong install cd? I do have both lying around.

That has been my suspicion since I found both CD’s lying together.

  • aluengas,

glad you got it fixed, but what do you mean with “wrong CD”?

Uwe

I have both 32 and 64 bit CD’s. I may have used the 32 bit one, which would be really embarassing. :shame:

But both should see all cores!
Anyways… Glad you got it solved :slight_smile:

hmm… did you check the BIOS settings, it turns out that was my problem in the first place.
