    That's handy that you've got the 4GB RAM working. I always seemed to have more problems with this board when all four banks were full, which also slows down the bus speed due to some chipset limitation. I never had any issues with just 2 banks when I had 2GB RAM. Back in the day I used to spend a lot of time on the ASUS message board when I had this board and some posters were adamant that they got this mb working with 8GB RAM (they would buy 2GB server RAM modules) I never got round to trying it, maybe that's a project for you

    Interested to know how you got on with an SSD on this machine, just out of curiosity of course. I was going to chance getting one at one stage but because it doesn't have an AHCI controller, I never did as I didn't think it would run optimally. Does it make a massive difference over a mechanical SATA drive for you?

    I know what you mean about the hobby of pushing old tech - got a Super Socket 7 board somewhere with a K6-2 500 and 512MB RAM, don't have the facility (case, psu) to fire it up sadly. But it was kind of fun getting Windows 10 working on the Asus A8N
    I only bought a cheap Plextor 128GB SSD and it does make a huge difference. I just connected it and it works. HWInfo reports it connecting at 1.5GB/s whereas the A8N-SLI supports 3GB/s. I doubt it makes much real world difference on the PC.

    I'm still trying various devious means to install Windows 10 64 bit!

    I've tried all means to install Windows 10 64 bit on the A8N-SLI motherboard and all attempts fail with the PC hanging at the first reboot. I've gone back to the 32 bit Windows installation which is fine but I can only use 3GB RAM.

    Please advise if anyone has cracked installing Windows 10 64 bit on 2004 vintage PCs like the A8N-SLI. I'm actually surprised I managed to install the 32 bit version of Windows 10.

    The CMPXCHG16b instruction is most likely not present in the processor's instruction set for the AMD Athlon 64 3000+ . This processor would have predated the specification, which was implemented as a requirement for the Windows 8.1 64-bit OS, preventing some Windows 8 AMD x64 systems from upgrading to Windows 8.1.

    There are several versions of this Socket 939 CPU out there - which one do you have?

    Check on List of AMD Athlon 64 microprocessors - Wikipedia to start with, and run the Sysinternals Coreinfo.exe program to check if the instruction is present.

    I ran CoreInfo before I tried the 64 bit installation and it reported CX16 - Supports CMPXCHG16B instruction.

    CPUZ reports the processor is a AMD Athlon 64 3000+, Winchester version , core stepping DH8-D0 installed in an Asus A8N-SLI Socket 939 motherboard.

    In theory the CPU should satisfy the requirements for 64 bit Windows 10. The PC is quite stable in 32 bits using the Windows 10 installed drivers. I have a Plextor SSD connected to a SATA port and note the driver selected for this is Standard Dual Channel PCI IDE Controller. I did locate a modified NForce 4 NVidia SATA driver from the Winraid site which works but the Plextor SSD tools fail to recognize the drive using this driver.

    I enclose the CoreInfo, CPUZ reports & and a device manager screenshot. I still suspect a BIOS incompatibility or driver problem when trying to install the 64 bit version of Windows 10. Any ideas?

    Sorry Steve - it does not support the CX16 instruction, note the lack of an asterisk *, and the presence of a hyphen - next to it, in your Coreinfo.txt

    * = yes
    but
    - = no.

    So, 64-bit versions of neither Windows 8.1, nor Windows 10 will install or run on it.

    Code:
    ...
    CMOV      * Supports CMOVcc instruction
    CLFSH      * Supports CLFLUSH instruction
    CX8        * Supports compare and exchange 8-byte instructions
    CX16      - Supports CMPXCHG16B instruction
    BMI1      - Supports bit manipulation extensions 1
    ...

    I wish I realised that a week ago and I wouldn't have wasted several hours of my life (not used CoreInfo before)! :(

    Thanks. I've marked the thread closed due to hitting this brick wall.
