    How to know my processor supports PAE, NX, and SSE2?


    Hello!
    My laptop is powered by an intel core i7 640m processor. I'm wishing to upgrade my system to windows 8 and i'v found, processor should be support PAE, NX, and SSE2 in windows 8 requirements page. In processor info section, PAE value is displayed as 36-bit and no any info about NX and SSE2 where can I find those information? or please tell me that the i7 640m processor supports those features or not and is it windows 8 ready?

    Thanks in advance before.

    Any Core i7 will support those things. However, you can always download CPU-Z and it will tell you what features your CPU supports.

    Another options is to look here:

    Intel Core i7-640M Mobile processor - CP80617004152AE

    It doesn't say PAE, but you can rely on any 64 bit CPU supporting PAE.

    Thank you very much for the immediate reply. I have a little hazard because my processor is first generation one. BTW where are those things located in CPU-Z ? I couldn't find em.

    Again, if it says EM64T then it's guaranteed to have PAE. CPU-Z should say right on the main page what versions of SSE are supported. NX is a little trickier, as this can be enabled and disabled in your BIOS, but the CPU still has to support it. If you have VT extensions (VT-x, VT-d) then you certainly have NX support. Again, the page I sent you to mentions NX and SSE specifically.

    As you're upgrading to Windows 8, I suggest using the Windows 8 Upgrade Assistant to check out your PC.
    Windows 8 Upgrade Assistant - Download and Run

    It will check if the processor has the right features (although I go along with Mystere and I don't think you have much to worry about processor-wise with an i7), and also look for other conflicts in software and hardware. It's not 100% foolproof, but it should give a good guide.

    Tip: download the Windows 8 Upgrade Assistant now, as I'm not sure whether Microsoft will "pull" it from their website in a week's time when Windows 8.1 is available.

    Piriform "Speccy" should show you all of the features of your CPU. There used to be a free program "Everest" but it was changed to a paid program, and I don't think there are any free versions of it, but Speccy should show you want you need to know. Ah, yes, "CPU-Z" should do it too, there are several property sheets that should show some info. You have to squint to look through them all.

I have a 6 yr old Dell Dimension E520 currently running Windows 8. I tried to upgrade to 8.1 but have been denied because my processor doesn't support PAE, NX or SEE2. I've read some posts that stated that this was an issue preventing them from installing version 8. It wasn't an issue for me...
