    At least it’s not a 1.2GHZ Atom! The Inspiron is a 1.2GHZ Sandy Bridge dual core so it’s probably equal to about a 2GHZ core 2 duo

    In most cases, hyperthreading will not help gaming. If by keeping hyperthreading disabled your computer temperatures are lower (this is especially important in laptops) then its better to keep it off

    Find a BIOS mod and flash your current bios to gain access to extra features.

    If only I had access to a y580 I would. Unfortunately I’m limited in what hardware I have.

    unfortunately many manufacturers limit the settings that will show up in your BIOS, effectively limiting what the end-user can do. There wouldn’t be any software solution to this as you aren’t inside the operating system. This is a hardware limitation that was imposed by the manufacturer of the motherboard or computer

    Well hyperthreading is supported by the processor but can’t disable it. 2 logical cores, 2 real cores in task manager.

    It means that your processor doesn’t support it.

    Hmm what if the hyperthreading option isn’t in the bios of my inspiron m101z with the core i3 1.2GHZ processor, is there a windows-software solution?

    Yeah it will be no problem, It won’t affect your performance at all in skyrim, It may even help because your CPU will be running cooler, and cooler is always better when it comes to electronics.

    You’ll just notice it takes a bit longer to load programs like photoshop or windows movie maker for example.

    Okay, but my i5 is a dual core processor that has hyper-threading, so it has 4 logical cores, will I be able to play games such as Skyrim and such on that?

    Unless your using a lot of programs like photoshop, and other things similar to it than it’s pretty much useless. Game’s don’t use it so its much more usefull to turn it off and save power/heat and you can even bump up your clock at that point.

    Is there a down side to hyper-threading? Is there a particular reason why you wouldnt want to have hyper-threading turned on?
