S2676 (Thunder i7525) Memory issue

    Hello,

    anybody an idea why Corsair DDR2-400 1024 reg. Memory (CM73DD1024R-400/S)
    doesn't work in the board Thunder i7525. CM73DD1024R-400/M ist recommended
    by Tyan, but the only difference is the Manufacturer of the Chips (in their
    case Micron, in my case Samsung).

    Beep code without memory is 4-4-1-2 with the memory installed nothing
    happens! So I believe the board and the CPUs are working...

    regards,
    Clemens

    May we assume you've installed a pair of memory DIMMs...? The board won't
    boot w/o a pair installed.

    Beyond that, it might be a chip density, or board density issue. Are your
    DIMMs populated on both sides with chips, or only one? Here's the Samsung
    chip spec. page (scroll down to "Registered DIMM"):

    http://www.samsung.com/Products/Semiconductor/DRAM/DDR2SDRAM/index.htm

    Here's Micron's:

    http://www.micron.com/products/modu...count=240-pin&version=Registered&package=DIMM

    Corsair ironically doesn't list a /M or /S version of the CM73DD1024R-400
    which leads me to believe the PCB for both offerings is the same. If in fact
    the PCB is the same, a logical conclusion might be that chip densities are
    also alike. That being the case, I can't imagine why your DIMMs won't work
    unless there's a subtle difference in power consumption between the Micron
    and Samsung chips...one that's taxing your PSU.

    According to the manual the board will boot up with 1,2,4,6,8 installed
    modules... I tried with 1, 2 and 4 identical modules.

    The modules are constructed with chips "K4T51043QB" on both sides 9 each +
    register chips.
    http://www.samsung.com/Products/Sem...AMcomponent/512Mbit/K4T51043QB/K4T51043QB.htm
    The modules are 1 rank modules. Does someody know whether the Modules sold
    by Corsair with Micron modules are also 1 rank modules (single row on each
    side) or 2 rank modules (double row on each side = total of 36 chips)?

    ....

    Can follow your argument concerning the organisation but I have also seen
    some changes years ago with Kingston 256MB SD-RAM - First double sided later
    single sided with the same type number!!!

    Does sombody know whether I can use DDR2-533 modules with the board so that
    I can verify which bios is on the board (if these chips are working)?

    regards,
    Clemens

    I stand corrected, you're absolutely right.

    ....problematic for the venerable BX board. ;-)

    Considering the problems you're experiencing with RAM of the same part
    number (though different chip mfr.), I'd make sure I had the ability to
    return any "test" RAM in case of incompatibility.

    Keep us posted.

  5. Thanks for your help

    Will keep you updated! Next I will try other brand (maybe DDR2-533 ... hope
    this is working).

    regards,
    Clemens

    P.S.: I will talk to my distri on monday to check the RMA or what to try
    next

    Hi Clemens,
    i have the same problem with my new Tyan S2676 Mainboard!

    With 1x or 2x Xeon CPUs and 1x or 2x Kingston 1GB RAM Modules in Bank
    1 (KVR400D2R3/1G) there is no Beep code, but Xeons will become hot.
    Without RAM i got Beep code: 4-4-1-2 (same like you)
    With RAM in Bank 2,3 or 4 i get this Beep code: 4-3-4-4
    I tested the System with and without Nvidia Quadro FX3400 (PCIe) and
    an older PCI ATI GPU --> only black Screen, no "normal" System
    Beep!

    Then i tested my Kingston RAM within a new HP XW8200 Workstation
    --> HP System boots fine!!!
    My Nvidia Quadro runs fine too --> RAM and GPU is OK!

    I am very confused with this Mainboard...
    I don´t belive that all two CPUs are damaged or something like that.

    Does anybody knows more about this strange Mainboard ?
    Or could it be the Power Unit ?!?

  7. Re: S2676 (Thunder i7525) Memory issue - Problem solved

    Solution:

    Get working memory (i.e. 512MB modules), format a boot-disk and copy the
    bios update on the disk.
    Start the S2676 with this disk, perform the update!
    After that you can swap to the new memory modules.

    If you are not able to get a working module call your local Tyan support for
    assistance.

    regards,
    Clemens

    Clemens, DDR2-533?? I'm afraid u can only use DDR2-400 RAM modules for
    your motherboard. 533 is for video cards. Hope u only mistyped.

    Good luck,
    Alan.

    Hi Wawa,

    Hope u've already resolved your problem. If not, just put one of your
    Kingston modules and upgrade the BIOS to 2.01 first & see whether this
    fix your problem.

    Good luck,
    Alan.

    I have exactly the same problem (same RAM, same PSU): The screen stays blank
    and no beep code with one or two modules installed. If I remove both modules
    I get 4-4-1-2. I currently only have an old PCI graphics card (nVidia Riva
    128) installed. Is using only a PCI graphics card supported with this board?
    The sticker on the BIOS chip says version 1.03. I assume I have to contact
    Tyan to get the current BIOS version to get things running. Was anyone able
    to solve this problem, yet?

    I believe there is no problem!

    Yes, I was! Upgrade your BIOS to 2,01 (you have to get working RAM - below
    1GB modules - first ;-) or call tyan for assistance (new BIOS)!
    Note: The BIOS chip is an SMT type socket - be carefull if you swap it with
    the one you get from tyan.

    Good luck

    I just received a new BIOS chip from Tyan, however it is still not working.
    Also with the new BIOS chip I do not even get a beep code when no RAM is
    installed.

    It is now working :) Tyan asked me to send in the board for RMA and sent it
    back with a working 2.01 BIOS.
