Power on failure when both DRAM slots used

  1. I have purchased a 2Gb kit on Ebay( 2 x 1GB DIMMs). When both DIMMs installed system beeps on power on probably indicating RAM failure. With 1 x 1GB in slot 1 system boots ok. With same 1 x 1GB in slot 2 system boots ok. With the other 1 x 1GB the system will boot up ok in slot 1 or slot 2.
    When both 1 x 1GB DIMMs are installed in slots 1 and 2 the system fails to boot.
    On the Gigabyte GA-K8VM800M MoBo I have, there are only 2 memory slots.
    It is Award Software BIOS & I cant find any reference to dual channel vs single channel memory anywhere in the bios pages.
    As both slots 1 & 2 will work independently the fault is not the MoBo. Both new 1 x 1GB DIMMs will work independently in either slot 1 or slot 2 so the DIMMs are proving ok.
    Somehow I need to switch to dual channel memory instead of single channel.
    Any Ideas folks?

    1 long 1 short: DRAM or M/B error
    1 long 2 short: Monitor or display card error
    1 long 3 short: Keyboard error

    Hi Kimsland
    Yep, I'm getting continuous long beeps.....DRAM error which is what I thought. This is only when both new 1gb DIMMs are installed in slots 1 & 2. I have tried them in my other machine which has a Gigabyte 7VM400M mobo & the system boots perfectly & detects 2gb with no trouble at all thank you very much. In this machine it just won't detect 2gb if both slots are used.

    All I can say is, some manufacture Rams don't suit some computers
    Also it may be the voltage rating on the Ram
    I don't know what your voltage rating is suppose to be, it may be in your motherboard manual.

    Adjust voltage to the spec of the rams.
