BIOS error Beep code/ Precision 670

This question has suggested answer(s)

Dear All,

Dell Precision WorkStation 670 cannot start up suddenly, which is showing the BIOS error.

The LED code is "green-yellow-green-yellow", which might mean memory error.

But the Beep code is

"1 (long)-3 (short)-2 (short)", which is not listed on the code chart.

Could you please let me know what this error means and how to solve?

I had already tried to replace memory, check the power-supply, and HD, but I could not solve

the problem yet.

Many thanks.

  • The only way to check the power supply is to replace with a known working supply.

    These Systems use a NON STANDARD power Supply unit.

    Memory modules are detected, but a memory configuration or compatibility error exists.

    • Ensure that no special memory module requirements exist.
    • Verify that the memory modules that you are installing are compatible with your computer.
    • Reinstall the memory modules and restart the computer.
    • If the problem persists, contact Dell.

    Diagnostic Lights

     CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.

    To help you troubleshoot a problem, your computer has four lights labeled "A," "B," "C," and "D" on the front panel. The lights can be yellow, green, or off. When the computer starts normally, the lights flash. After the computer starts, all four lights display solid green. If the computer malfunctions, the color and sequence of the lights identify the problem.

    1. Reseat the memory modules to ensure that your computer is successfully communicating with the memory.
    2. Restart the computer.
    3. If the problem still exists, remove all the memory modules and install one memory module in memory module connector 1 (DIMM_1).
    4. Restart the computer.

    The following message appears: Alert! Operating in Debug Mode. Please Populate Memory in Pairs for Normal Operation.

    1. Press <F1> to boot to the operating system.

    3. If the memory module passes, shut down the computer, remove the memory module, and then repeat the process with the remaining memory modules until a memory error occurs during start-up or diagnostic testing.

    If the first memory module tested is defective, repeat the process with the remaining modules to ensure that the remaining modules are not defective.

    1. When the defective memory module is identified, contact Dell for a replacement.

    NOTE: If necessary, the computer can operate in debug mode until new memory modules are installed.

    Beep Codes

    Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. One possible beep code (code 1-3-1) consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the computer encountered a memory problem.

    If your computer beeps during start-up:

    1. Write down the beep code on the Diagnostics Checklist.

    2. Run the Dell Diagnostics to identify a more serious cause.

    3. Contact Dell for technical assistance.

  • Thank you very much.

    I had checked these charts, therefore, checked the memory (replaced with the others, but no success).

    But the Beep code is 1-3-2 (for my ears), which is not listed. So, I am wondering what this means.

    The power lamp is Solid green.

    I would be grateful if you could think of any solution.

    Also, could I assume that BIOS itself is not corrupted?

    Many thanks.

    Maximum Memory: 16GB
    Slots: 6
    Each memory slot can hold DDR2 PC2-5300 with a maximum of 2GB per slot.*
    *Not to exceed manufacturer supported memory.

    Installed in pairs of modules.

    If more than 4GB of memory is installed, you must install an additional cooling fan.

    Please contact Dell for more information at 1-800-999-3355

    When dual ranked parts (currently 2GB and larger parts are dual ranked) are used in banks 3 and 4,

    then banks 5 and 6 must be left empty.

    How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found here.

  • Thank you very much.

    I am using much smaller memory on WInXP (32 bit)

    The original memory (shipped from Dell) had 4 x 512MB, that is,

    - 2 x 512MB 1Rx8 PC2-3200R-333; and

    - 2 x 512MB 2Rx8 PC2-3200R-333,

    both of which seem to be different from yours, but had been running for over 5 years.

    I then thought one or more of these might be damaged and tried only with each of the pairs, and

    tried with the other pair (had been used on the other machine).

    Would you mean that I should try with brand new memory, not with the used ones?

    Many thanks.

  • Mixing ranks is not allowed.   1RX8 should not be paired with 2Rx8

    PC2-3200 IS TOO SLOW.  PC2-5300 667MHz is called for.

    All indications are that the ram is the wrong kind AND is bad.
