Thread: Two cpus... not?

  1. #1

    Default Two cpus... not?

    Well I have just recently installed Suse and was excited about how fast I was able to get multiple monitors working (ubuntu wasn't working for me). Now I have been using it for a few days and find that things are *randomly* freezing and not opening. I believe that it could have something to do with the system monitor saying that I have two cpu's. To clear this up, I have a p4 3.0ghz LGA 775, and possibly most importantly 1 core. Not only does it show two cpus but it shows them both as active(by the way this image was taken while only on firefox, yet look at the useage):



    Any help on this would be much appreciated, thanks.

    this looks like a "hyperthreading" CPU.

    Now I feel a bit dumb, yes it is hyperthreading, so that does explain the two cpus, however that doesn't explain such high usage and the common crashes. Thanks for explaining that though,

    Probably hyperthreading... all OS's do this. To disable go into your
    BIOS and disable hyperthreading.

    Good luck.

    Are you saying that hyperthreading is the cause of the crashes, or just the reason for 2 cpus?


    UPDATE: i turned off HT and that was the reason for 2 cpus, however right now i have a constant cpu useage of 50%+ with only firefox open so that did not fix lag or crashes.

    Heres an example of how my cpu is acting:

    the straight line in the beginning is just firefox open with nothing else happening, when it starts to go up, that was me scrolling the page, it goes from 30% up to 100% from just scrolling?

    I'd guess that beagle is installed if it is by default, To find it I went to a search application and typed in beagle... is that not the way to do it? Anyway why is it important if beagle is installed?
