  1. Upgrade to Windows 10 64 bit PAE, SSE2, NX, CMPXCHG16b


    I have a AMD Athlon 64 X2 Dual Core 5000+(64-bit processor) and I'm thinking it can't run WIndows 10 64-bit. One website said to check under System Information "Look for system type if you see x64 based PC, then your computer is capable of running 64-bit Windows. If you see x86 based PC, then you can't install another architecture of the operating system." Well it shows x86 based PC despite my 64-bit processor. I want a CPU that is capable of running it, but everything I find online how to check if it is compatible, only works if you already have the CPU installed.

    What I've found is that in order for it to run Windows 10 64-bit, the CPU needs to be SSE2, PAE, NX, and CMPXCHG16b compatible. But I have no idea how to check for that without physically having the CPU. A thread on this site, a user named Carsomyrclaims this datasheet for an AMD Athlon II X4 640, is compatible with all those things. But when I check it I can only find the compatibility for SSE2, and PAE (listed as AMD64).

    I searched the same site for a datasheet for an AMD Phenom II X4 850 (the processor I'm looking to buy) and again found only the compatibility for SSE2, and PAE (again listed as AMD64).

    So basically I want to know what information on those datasheets indicates that is compatible with those features, or if user Carsomyr is mistaken. If the AMD Phenom II X4 850 is compatible and will let me run Windows 10 64-Bit. Or should i keep looking.

    Here is my Motherboard Specs with a list of compatible CPUs.

    Windows 10 adv CPU isnt supported - Intel Xeon

    In reference to the above:

    3.1 Processor

    Devices that run Windows 10 for desktop editions require a 1 GHz or faster processor or SoC that meets the following requirements:

    • Compatible with the x86 or x64 instruction set.
    • Supports PAE, NX and SSE2.
    • Supports CMPXCHG16b, LAHF/SAHF, and PrefetchW for 64-bit OS installation

    - It isn't very clear, does it have to support all 3: PAE, NX and SSE2 or just meet one of these requirements?

    as for the 3rd option well I'm not sure about that, could do with some info there.

  3. What are the system requirements for windows 10 ??

    My understanding is that Windows 7 and Vista didn't need SSE2, NX, and PAE? I remember only 8 saying such things. I've read that people with Windows 7 can upgrade to 10. I have an OLD IBM NetVista 8319 with a Pentium 4. It couldn't upgrade to 8 (SSE2,
    NX, and PAE) but I guess Vista and 7 it could.

    My Questions is does 10 really require SSE2, NX, and PAE? If not then my 2.4 GHz P4 8319 PC with 1GB Ram and 40 GB hard drive could run it. If so, then I guess i'll put down $119 or whatever 10 will cost. I'm keeping Windows 8 on my P7. I just love that
    OS. But 10 will make my old PC useful again. Upgrade to Windows 10 64 bit PAE, SSE2, NX, CMPXCHG16b :)

    Upgrade to Windows 10 64 bit PAE, SSE2, NX, CMPXCHG16b

    Any CPU, no matter what it's capabilities, will show as "x86 based PC" when running on a 32 bit OS. That is the information given to 32 bit applications for compatibility reasons.

    I believe that CPU will run run Windows 10 without issue. The only possible problem might be "CMPXCHG16b" Many data sheets do not show all relevant information.

    I've seen some computers running Win10 that specifically showed the OS as 32-bit running on 64-bit processor in System [right-click the Start button], System type line. Mine shows 64-bit OS on 64-bit processor, don't have the 32-bit version running just now.

    I'm playing around with a Athlon 64 3000 CPU on Socket 939 from 2004 and found this post searching the forum.

    See https://www.windowscentral.com/how-u...ion-windows-10

    According to Microsoft's support page in Windows 8.x and later, the operating system requires three essential characteristics, including Physical Address Extension (PAE), No-eXecute (NX), and Streaming SIMD Extensions 2 (SSE2). Additionally, Windows 10 (64-bit) also requires CMPXCHG16b (CX16) feature to be present in the processor.

    The Windows Setup wizard always checks for hardware compatibility before the installation begins. If these features are not supported by the processor, Windows 10 won't install. You can use CoreInfo from Sysinternals to check whether your CPU supports these features. My Athlon x64 CPU reports it does have the required features so higher spec CPUs like the one mentioned in post 1 should be fine. I already have Windows 10 FCU 32 bit version working quite well so I'm going to try clean installing the 64 bit version over the weekend.
