Windows 10: "CPU isn't supported"

If you can borrow a disk, you can try. First run the utility to get GenuineTicket.xml as described in this post. Then clean install Windows 10 32-bit and if completed successfully, you can try installing drivers. If everything is good, you can keep a full backup or clone the original disk and proceed to install Windows 10 32-bit on her. Use the file to activate as described in the post. If I was in your place and had a spare disk, I would do it for curiosity. Besides, sooner or later she will have to upgrade or install Windows 10, because of newer applications and/or devices.

 

I tried both Coreinfo and AIDA64 (I used Extreme instead of Engineer) on my AMD4000+ system, Coreinfo reports CX16 * Supports CMPXCHG16B instruction, while AIDA64 reports that it is not supported.

A bit confusing to have two different programs with different results on the same test, but I'm guessing since one is reporting no support then that's probably the case?

 

Solved with a repair install !!

Thanks

 

So should I look further into my Coreinfo and AIDA64 results? I wonder if one reporting supported means that there's a BIOS setting or something else that needs to be changed? I'm hopeful...

 

NX/PAE support might be set from the BIOS, in CPU features section. But I don't recall any setting for enabling the relevant instruction to make your CPU compatible with 64-bit Windows 8 and 10. It either supports it or not, you cannot select it from BIOS. See Aida64 for command support.

 

you did an install of windows 7 64 bit and did a repair install to get windows 10 installed? not sure i follow..

i misquoted my Coreinfo results earlier, mine has the "-" and not the "*". Does one mean supported and the other mean not supported?

 

X64 versions of windows 10 have the exact hardware requirements that windows 8.1 x64 has,that is a x64 CPU that supports PrefetchW,Compare exchange 128,and LAHF/SAHF.For most systems capable of running windows 7 at a decent level ,PrefetchW and LAHF/SAHF is a non-issue since these instructions are implemented since the first Athlon 64 days.For AMD,no CPU running on socket 754 or 939 is capable of running x64 versions of windows 8.1 or 10 without some serious modding of the setup files.On the Intel side,things are a bit more complicated since some motherboards have old BIOS versions which do not expose the cpus complete instruction set,some report that q9xxx series CPUs have issues with these instructions despite the fact that all the Instructions are supported.I run w10 x64 on a q6600 without issues.The oldest x64 capable CPU that I installed windows 10 x64 was an old AMD turion x2 tk56.For everyone else reading,if you have any CPU since Nehalem(included) you are 100% capabile* of running windows 10 x64.All Atom CPUS that are x64 capable also support w10 x64.
*The Intel g3528 has issues with the windows 10 setup due to faulty microcode within the windows 10 setup.While the processor is fully capable of running w10,it appears that the install process fails with a SAFE_OS message regardless of the CPU state.A temporary workaround is to disable all overclocking and one core.

 

@flashh4:Solved with a repair install !!?
can provide details and description how u made it?did u install win 10 64 bit ?
facing same problem while trying to clean install win 10 64bit on e8500(freeze on win logo itself) but can install win 10 32bit on e8500
Thank you

Hello!

As suggested in my previous post, install Aida64 and see the CPU instructions supported by your CPU. If it doesn't support the specific instructions mentioned by another poster, then don't try in vain. You cannot install the 64-bit version unless you hack the kernel. Hacking the kernel in Windows 8 and 8.1 works without any problem, but in Windows 10 you keep getting an error message that some system file is modified (signature test fails) and asked to troubleshoot. To boot your computer you have to go to the troubleshoot menu and then select the 7 option (disable driver signature) EVERY time. No matter what I did I could not do to automatically and get rid of this requirement. So avoid 64-bit if your CPU doesn't support it. Besides if you have up to 4GB RAM, there is no point installing the 64-bit version. Go for the 32-bit version instead, unless you have more than 4GB RAM (unlikely). I doubt there is any performance difference either, and the compatibility of 32-bit version is far greater for older devices and applications. Another reason to stay clear from 64-bit version if you have an old computer! I speak of experience!

 

Thank you for your reply .but on 32bit i can use only 3.12 out of 4gb ram .so can't play hd videos smoothly.but on 64 bit it is good .thats why trying.with AIDA64 ENGINEER I checked e8500 does not support cmpxchg16b.

 

Also is there any list of processors that supports win 10 64 bit?

 

Any Intel socket 775 CPU greater than the first two families (500 family was first 32-bit s775 series, 600 family was first s755 64-bit series) has a chance of being compatible. To make sure use Aida64 and check if these instructions are supported. If they are, then go for 64-bit. If they aren't go for the 32-bit instead. The less RAM supported should not affect the graphics performance. To get best performance make sure you have Intel graphics drivers installed, not generic Microsoft driver from Windows Update!

Today I found my old Pinnacle Studio PCTV card and my also old Creative SoundBlaster Live! 1024 card and tried to install these in my test PC that has Windows 10 Pro 64-bit installed. For the SoundBlaster, I tried to install the official Creative Windows XP x64 driver since no newer was available. The first error message was that this driver was unsigned, so I restarted with "disable driver signature" option. I managed to install the driver, supposedly OK but no sound was produced from the speakers! I then tried to install the generic Microsoft Vista & 7 64-bit driver which I had sometime downloaded from Microsoft Update Catalog only to discover it cannot be installed in Windows 10 64-bit (and probably in Windows 8 64-bit as well). There was an error message about some files missing. So tough luck. I then tried to install the Pinnacle TV tuner card with some hard-to-find third-party BT848 drivers I had downloaded in the past for Windows 7 64-bit. The audio device could be installed but the video device could not! VERY annoying!

So my advice is to stay away from Windows 10 64-bit if you have an old computer with up to 4GB RAM. Even if the CPU supported the 64-bit version and you managed to installed it, you could have issues with your old devices. Why bother? The difference between 3.25GB and 4GB RAM is not too big to worth the trouble. Let alone that there should not be a full 4GB because of the shared amount by the Intel graphics card. So do yourself a favor and forget it. Install 32-bit instead with proper drivers for best performance and - most importantly - best compatibility. I wasn't kidding when I told you I speak of experience. I have lost countless hours to make stuff work in 64-bit only to give up and replace them with newer components that have 64-bit drivers.

 

i think e8500 greater than first 2 families right.i have e2180 and e6600 working on win 10 64bit.i heard updating bios may help.is it possible.my motherboard is zebronics nf 7050 and chipset nvidia nforce 610i .i got only .rom file from zebronics website.how to use this file to update bios?

 

Look again at the BIOS download site if any utility is mentioned and download it. It could be in the Applications/Utilities section. If you have Award BIOS or Phoenix or AMI there are specific utilities that work in all motherboards, but the safest is to download the utility from the motherboard's own web site. If the utility is DOS based, you need a way to boot into DOS (command prompt) to use it. One way is to use an old Windows 95 or 98 CD-ROM and boot into the command prompt. If you have a floppy disk drive, you should copy the BIOS there, as the DOS cannot normally access an NTFS hard disk to get it from there neither can access your USB Flash drive. It might be able to access your USB Flash drive if you connect it before you switch on your PC and then enable the legacy USB options in BIOS, but this is not always supported. Of course your USB Flash drive should be FAT32 formatted and as small as possible to improve compatibility (drives over 4GB may not be recognized properly). Read the utility instructions of how to use it.
