Pinned topic x3400 7975 not detecting RAM in memory module DIMM 7,8,10 and 11

‏2012-06-12T04:17:06Z |
Hi Experts,

I need your assistance very bad, my cpu cant detect all memory located in branch 1.
Currently I have 6 memory card each card have 1Gig each. It only detects 4gig instead
of 6Gig.

As I have observed all memory that will be placed in DIMM slot 7,8,10 and 11 is
not detected.

Hoping you could assist me in this matter.
Your favorable response is very much appreciated.

Note: Current BIOS is 1.74, 1.86Ghz processor.

Thank you.
Clint

    Clint,

    How much memory do you have in total? Are you following the proper population sequence?

    Assuming you aren't mirroring, your 6 DIMMs should be in slots 1,4,7,10,2,5. The order is very specific so they must be installed in those slots.

    Hi,
    Sorry for the late reply.
    Yes I have followed the sequence.
    The weird this is there is no error message or light coming from
    computer or in the motherboard.

    Replaced with other memory cards but DIMM slots ,8,10 and 11 does not detecting it.

    Is there any update or configuration I missed?

    Thank you.,

    Hi,

    I have 6 RDIMMs, 1GB each, it must be 6Gig RAM all in all. It cant detect RAM in slots
    7,8,10 and 11, thats why currently I have 4Gig RAM detected.

    I can give you later the P/N of the RDIMM of the server since it currently in used. I need
    to schedule the shutdown.

    I have also tried transferring and swapping memory detected from slots 1,2,3 and 4 from
    slots 7,8,10 and 11 but still only 4Gig detected.

    Hoping you could assist me on this matter.
    Thank you.

    Sir Alex,

    Already done the sequence per slot.

    I even tried inserting first the 1,4 slot detecting 2Gig.
    After that insert 7,10 did not detect RAM.
    Then insert 2,5 detects 2 RAM.

    Thank you.

    Hi,

    I have removed the non compatible RAM.

    Remember I have P/N: 38L5901=FRU 39M5781 = 512 MB PC5300 ECC.

    I have 6 of them and total RAM result must be 3 Gig

    I Inserted it but it only detected 2Gig.

    I have used a compatible memory card but does not resolved my problem.

    Any other options?

    Thank you in advance.

    Hi,

    Upon further evaluation of the motherboard I have found 3 bloated capacitors
    this is why my memory is running abnormal.
