    Support for 6 Core CPUs

    Greetings All,

    I have just purchased an AMD Phenom II 1055T 6 Core CPU to replace my aging CPU. The problem is only 1 core is visible to Ubuntu, Does it actually support 6 cores?

    Good question.

    Anyone know if it even treats quad cores (like mine) well?

    Anyone know of any benchmarks?

    I would be happy to do a benchmark if I can get everything working

    I've seen one guy post who said he had 24 cores. I don't know how legitimate that was, but I can confirm that my dual core is supported, and I've seen quad-cores work fine, so I have to assume that quincore and sexcore processors are also supported. Where are you seeing only one core?

    Are you sure the motherboard supports the processor? I ask because it's not in this list (yet):
    http://www.msi.com/index.php?func=pr...3&maincat_no=1
    (You'll likely have to update the bios.)

    For proof that the processor works with ubuntu:

    [SOLVED] Support for 6 Core CPUs

    Hello All,
    I got a new motherboard and BAM it works perfectly. This machine is a monster. Here is a benchmark.I have also added a few screenshots as well. Enjoy

    Re: Support for 6 Core CPUs

    The motherboard was incompatible with the processor. According to the lshw, You have an MSI K9N6PGM2-V2. According to MSI's website, the K9N6PGM2-V2 only supports 95W processors, and you were using an AMD 1045T which is 125W. The motherboard or processor must have has some sort of feature which disables all but 1 core so the computer would be usable. I am not trying to sound harsh, but it is important to check and make sure that your motherboard and processor are 100% compatible, before even installing the processor, because it could cause severe damage to your system. I am glad to here that you got it working though.
