Computer will not boot with 4GB RAM after upgrade from 4200+ to 5000+

  1. I have 4 identical 1 GB memory modules and CPU Athlon 64x2 4200+ and everything work OK.

    Then I upgrade the CPU to the same type but 5000+
    Now I can't boot. Not even go into BIOS. I get a continously beep from bios.
    If I remove one RAM-module I can boot OK.

    I have tried to remove different memories, but as soon as I have more than 3GB I can't boot.

    I have also tried with 2GB memory modules. I can boot with one module inserted.
    But as soon as I have 2 modules I can't boot.

    I have tried to install kb929777 but failed. It says it's not for my system.

    How can I boot my MB with 4GB memory together with my new 5000+ CPU ??


    MB = Asus M2N-E SLI
    DDR2 = Vdata DDR2 800MHz

    I have everything set to AUTO in BIOS and I have the latest 1201 version.

    Increase the RAM's voltages a bit...

    I have tried that. Up to 1.95V
    Didn't work ...

    I have been Googling a bit and I have seen many people having similar problem.

    I think this might be a MB/Bios problem ..

    Since you mention the BIOS, have you upgraded to the latest version ? Maybe your new CPU isn't properly supported on the version you're currently running.

    I have the latest 1201 bios
    In the supported CPU-list for this bios it says:

    Athlon 64 X2 5000+ (CS),1MB,rev.F2,89W,SocketAM2
    Athlon 64 X2 5000+ (CU),512Kx2,rev.F2,89W,SocketAM2
    Athlon 64 X2 5000+ (CZ),1MB,rev.F3,65W,SocketAM2
    Athlon 64 X2 5000+ (CZ),1MB,rev.F3,89W,SocketAM2
    Athlon 64 X2 5000+ (DD),1MB,rev.G,65W,SocketAM2
    Athlon 64 X2 5000+ (DO),1MB,rev.G2,65W,SocketAM2
    Athlon 64 X2 5000+ (DS),1MB,rev.G2,65W,SocketAM2

    Everest reports my CPU to be a BH-G2.
    So I guess it should be supported ??
    I have no idea what (DO) or (DS) means.

    consult the bios beep guide in the guides forum.

    There is a continous beep. Indicating memory error.
    But only when I have more than 3GB RAM.
    And only when I use 5000+ CPU

    Everything OK with:
    4GB RAM and 42000+CPU OR 3GB RAM and 5000+CPU

    My MB recognize the 5000+ CPU and has no problem using 4GB with my 4200+ CPU.

    But the combination 4GB RAM and 5000+CPU fails.

    I have sent in a question to ASUS.

    read my guide regarding ram in the guides forum. ASUS is a brand that is very picky on ram.

    Can you manually lower the memory speed ? Try running it at 667MHz or even 533MHz.

    SUCCESS !!

    I registered at ASUS website.
    In their forums i found several people having the same problem..

    IT IS A BUG IN THE LATES BIOS 1201

    Downgraded to 1102 and now it works OK.

    How the H.LL can ASUS keep 1201 on the site ??

    Anyway, thank's for your support guys.

    You know what ??

    I just got a mail from ASUS support.
    They suggest that I shall use the latest firmware 1201....

    I wonder if they even read the mails before they routinly suggest:
    "make sure you have the latest firmware"

    :rolleyes:
