Linux mint 13 "Mate"

 

I have an AMD 6 core CPU but in system monitor it only reports as 1 cpu. It is also heavily loaded at all times over 15 percent at a minimum, before it would show each core and on an idle system It would be odd to see a core jump over 5 percent. So it seems like the system is running on only one core. I have also tried a fresh install.

 

What are some steps I should take before I go to another distro to see if the problem persist and start wonder if my CPU/Sysboard has gone bad.

I had Linux Mint 13 mate running fine on my desktop, which is an i7-2600k. I did a search on your cpu and mint. Only thing I found was this so it seems it should work. But what it looks like this person is running LM13 in a virtualbox so that may make the situation a bit different. I did a search on supported hardware and it seems like it's not listed there. So it I would think the cpu isn't supported by Mint and I can't find anything else on the net on it. to do a full install first. Could you try running the following commands and post the output?

 



Code:
lsmod | grep cpu


to see if the cpu modules are loaded



Code:
lscpu


to see how many cores it actually sees under cpu(s)



Code:
grep -i --color "model name" /proc/cpuinfo


to see the cores it sees running

 

 

Instead of installing a whole new distro you also try running it from live cd's also to see how it runs. But lets just see what the results of this is first?

I will run those commands when I get home. It's odd that it was working. I just cantimagine that all of a sudden 5 cores went bad on my CPU but it still funtions. Like I said I'll try another OS and see how many cores it recognizes.

SOOOO

 

I downloaded Ubuntu 12.10 to test the system on a live CD and FELL IN LOVE. Ill never know why Mint only recognized one core becuas I just simply installed Ubuntu. I know it's just a RC but it is sexy, elegant and fast! It didnt freak out with my new Nvidia video card either.

 

 

 

Now to configure conky all over again.

Well glad you got it working now, but now you weren't able to figure out what the problem was after you did a reinstall.
