I am getting DIMM1 and DIMM2 not the same. I checked the mother board and there are two slots instead of the 1 that ACER web site says. Also, only using one slot with an 8GB card. any ideas ?

    What do you mean by you're getting DIMM1 and DIMM2 not the same? Jack E/NJ

  • Some versions come with a ddr3 or ddr3L, see:

    In addition, there are two ram slots:

    picture of mother board....
  • Your model has a main board with different revision. Which of the slots does the ram not fit correctly in?

    If it was working OK with both sodimms then you got the error message, then one of the sodimms probably became defective. Maybe try swapping the sodimms or clean their contacts with a soft cloth. Jack E/NJ

    tried putting it in the other slot....would not even start...worse off...at least before it seemed to have some life. lousy design for repairs. have to disassemble the whole thing apart to get to the memory slots

    Sorry. A significant fraction of new RAM modules do fail typically very soon after being installed like this.  Jack E/NJ

  • There are two possibilities:
    a) ram memory is defective;
    b) or you will need to update the bios.

    Can you inform the model of the original ram and also what is failing?

    To recap, The PC was working fine and then all of a sudden I started getting the DIMM1 and DIMM2 module organization not the same. I did not try to install any new additional RAM, I did not change anything. The original RAM is a KIngston 8GB DDR3. If I put it in the second slot, the PC does not start at all. If i put it back in its original slot. I get the DIMM1 and DIMM2 error message and PC will not start. As it will not start, can't get into BIOS to do any diagnostics, nor can I update the BIOS, assuming there even is a more current version than what I currently have.

    I'm still somewhat confused by the ACER specs that say this model only has one expansion slot when there are 2 ?
  • Can you send from the original ram? I want to make sure it is a DDR3 and not a DDR3L.

    I have reassembled the PC, but pretty sure it was DDR3.

    Appreciate the suggestions, but not sure what use sending the original RAM would accomplish ? I haven't changed anything (hardware or software wise) so what ever the issue is is not related to introducing new hardware or configuration changes.

    still odd that there are 2 expansion slots on the mother board. Must be generic I guess and some models of ACERS can accommodate the extra slot.

    @egydiocoelho would like you to send a phone shot of the original RAM so we can tell if it's DDR3L or LOW 1.35volt RAM or earlier DDR3 or HIGH 1.5volt RAM. Jack E/NJ

    Getting to the RAM is quite a chore, and I have reassembled the PC and closed it up. If this is not to confirm what the original is so I can buy a replacement, Can you share with me why this would be important to know ? Also, hesitant to buy a replacement as it could very well be the mother board or something else that is "fried". Thanks

    If you tried putting a 1.35volt DDR3L module in a socket that runs it at 1.5 volts, the module may have burned out. If you tried to put a 1.5 volt DDR3 module in a socket that only runs it at 1.35volts, it may not work properly or at all. Jack E/NJ

  • It is important, because some versions of your laptop support ddr3 while other versions support ddr3L, see:

    Some chipsets accept both ddr3 and ddr3L. However, others only accept ddr3 or ddr3L only.

    ok, this is what I did. First, the PC was working fine. I did not change anything and I started getting the DIMM1 and DIMM2 module not same error. AT that point the PC would not start up. Assuming it was a RAM issue I opened the PC up and discovered that it was a major chore (take the whole thing apart) to get to the RAM. That is where I saw there were two slots. One had a memory chip (Kingston 8GB DDR3) in it, the other didn't. So I was curious why 2 slots when the ACER specs say only 1, with a max of 8GB. In any case, I tried putting the chip in the second slot and the PC would not start at all. Put the chip back in the original slot and back to error message. So, my assumption now is it is a mother board or some other issue.
