    Dell Dimension E520 ... CPU Not Compatible?


    I'm trying to solve the mystery of why I cannot upgrade to Windows 10 Pro 64bit on a Dell Dimension E520. The Windows report shows that the CPU is not compatible.

    I've researched the problem a little and discovered that other people seem to be running windows 10 on this hardware although Dell isn't releasing specific windows 10 drivers. It's an all-Intel system, ICH8

    I've got the latest BIOS flashed and NX is enabled.

    Here's a dump from coreinfo:

    I have a Dell E310 with a Pemtium 4 HT processer and it is running Windows 10 just fine. Are you trying to upgrade through Windows Update? I made a Windows 10 install USB stick and started the upgrade from the desktop. Plug in your USB stick and double click on Setup.exe. Either that or make a Windows 10 DVD and start the upgrade with it. From the Desktop put in the Windows 10 DVD and when Setup.exe pops up click on that. Your upgrade should start. Don't try to do the upgrade through the Windows Update.

    Found it.

    To install a 64-bit OS on a 64-bit PC, your processor needs to support CMPXCHG16b, PrefetchW, and LAHF/SAHF.
    I could probably install the 32bit version.

    (Through a clean install)

    I had a Dimension E510 (same as a Dimension 5150) and it struggled with Vista 32 bit (upgraded from the original XP). With a max 4GB of memory there was no reason to use a 64 bit OS.
    I can only imagine how "great" it would work with newer Operating Systems.

    Windows 7 Pro 64bit was running okay on this machine however it was not being used for games or anything like that. At one point with a Radeon HD 6450 installed I saw a windows experience index of 4.2 The machine still lives, so I'm trying to keep it as up to date as I can. It's a bit of a hassle, but I'm still considering a backup and clean install of the 32bit version of Windows 10 Pro. It means only 3GB of memory however which I'm not really all that pleased about. Sure would be nice if Microsoft's easy transfer or something accounted for this 64bit to 32bit situation. I guess I can try to find a better 64 bit CPU - if the E520 will support it

    I can install an E6700 or Q6700 according to

    I'm not entirely certain that will solve the problem. But I see people selling these relatively old processors for $35 or less! Worth it for extra cache.

    Keep in mind the only real reason to use a 64 bit is if you have more than 4GB of RAM. 64 bit OS will address more than 4GB, where the 32 bit will not. However, a 64 bit OS uses more of the basic memory so there is less available for programs.

    Yes, in this case, 1GB would be video card memory, leaving me with only 3GB addressable system RAM using 32bit. If I can upgrade the system slightly for $35 and get the easy upgrade path to Windows 10 I'm going to do it.

    It looks like others have had success with 8GB with a 64bit OS on the E520 here:

    Just FYI: I have a Dell Dimension E520 (the one I'm typing this on) that originally came with Windows XP, a Core2Duo cpu and 2 G of ram. I long ago updated it to 8 G of ram and a Core2Quad Q6700 four core cpu and it has run XP, Vista x64, 7 x64, 8 x64, 8.1 x64 and now Win 10 x64 without any drama.

    Bit of an old thread, but since the Win-10 upgrade period is ending soon, figured I'd chime in.

    I just updated a similar computer, a Dimension 5150, from XP 512 megs to Win-10 32-bit with 3GB.
    I also had problems going to 64-bit so I swapped in a faster D945 processor when upgrading to 64-bit.

    The old hardware runs nicely under Win-10 64-bit even with only 3GB of memory for my setup.
    The upgrade to 64-bit didn't get me any more ram (a 5150 only sees 3.25GB max) but 64-bit OS
    has other benefits, it allows you to run the 64-bit versions of web browsers, more secure, more stable.
    Also, it seems like there is better support for peripherals with the 64-bit drivers.

    All in all, definitely worth it to basically have a brand new PC.
