Computer freezes during POST at memory count

Posted on 2005-04-09
Last Modified: 2012-06-27
AMD Athlon 64 3200+
MSI Neo4 Platinum / SLI Motherboard
1GB (512x2) Kingston PC3200 RAM (model verified against compatibility list)
Maxtor 160GB SATA HD
Lian Li aluminium case
17" AGNeovo LCD

This computer is newly assembled from new components. When booting, the POST memory count stops at 1024k and the system freezes. It will not progress, and does not respond to anything but a reset or forced power off.

1) I have tried resetting the BIOS
2) I have replaced the Motherboard
3) I have tried 4-5 different pieces of RAM, different manufacturers
4) I have tried different video cards
5) I have tried unplugging everythingm even HD & DVD drive

I'm at my wit's end with this. I've already had two RMAs from my wholesaler to get new parts, but nothing changes. I could really use some help here.

    That board has memory stability problems with some chips with the BIOS default settings. Get the spec's on your memory chips and try manual settings in the BIOS.
    Main Memory
    • Supports dual channel DDR 266/333/400, using four 184-pin DDR DIMMs.
    • Supports the memory size up to 4GB  
    • Supports 2.5v DDR SDRAM DIMM  
    Due to the High Performance Memory design, motherboards or system configurations may or may not operate smoothly at the JEDEC (Joint Electron Device Engineering Council) standard settings (BIOS Default on the motherboard) such as DDR voltage, memory speeds and memory timing. Please confirm and adjust your memory setting in the BIOS accordingly for better system stability.
    Example: Kingston HyperX DDR500 PC4000 operates at 2.65V, 3-4-4-8, CL=3.
    For more information about specification of high performance memory modules, please check with your Memory Manufactures for more details.

    Thanks ... but I can't get INTO the BIOS ... it freezes during the memory count, right at the beginning of the POST.

    Hi RKFcomputers


    This CPU has inbuilt memory controllers and has direct access to memory.
    Off course the path is via Motherboard, but No nortbridge is involved, as it usually is.
    Which new parts did you get  ?

    Have you tried it with just 1 RAM stick ?

    Hi RKFcomputers

    Just after memorycount, all the rest of hardware kicks in, meaning a high power draw.

    What PSU do you have ?

    Author Comment

    The system is all new parts - and I have tried with at least four different memory sticks.

    It locks during the memory count, always at 1024k. It never gets past there.

    The power supply is an Nspire 450W PSU - ATX 2.0

    Hi RFK

    Do you have a D-bracket to view post states ?

    It locks during the memory count, always at 1024k

    sure its 1024 K(ilo) and not 1024 M(ega) ?

    Absolutely sure - it says 1024k

    The D-bracket halts showing "Bios Sign On" - a perfectly happy state. No CPU or memory errors on the D-bracket.

    Hi RKF

    Sounds like a tough one.

    D bracket does not actually point out a specific error, it just reveals the POST process state, so most of them are happy states.

    What puzzles me is that it only shows 1024k, thats only 1 Meg. In my head something like GATE A20 options pops up which is a MOBO function if you want to utilize memory above 1 Meg.

    Only showing 1024 K means it fails during memory things, if it showed 1024 Meg, it probably fails entering the next POST state.

    How about an "out of case experience" for the parts to eliminate anything shorting on case?

    And do a minimal config.
    MOBO, CPU, 1 stick of RAM, GFX, PSU

    Maybe try out another PSU ?

    Even if anything is new. It does not mean it works

    Ok found it ...

    Case issue, faulty wiring.

    In the process, I've acquired 3 PCI cards, and two new bald spots.

    Some days I wonder why I'm in this business  :)

    Sometimes we learn the hard way, the good thing about this is, you'll never forget.
    Unfortunately it always have a cost, $$ and bald spots ^o^

    Maybe get an MSI cap, for them spots

    Glad to hear, you got it sorted out.
