  • Memory problem

    Hey guys!

    I have installed 4 x 1GB memory chips in my computer. Still, the bios, and Windows, only lists 3,25GB. Why is this? I have updated the bios to the latest version, and have tried to contact Gigabyte tech support. No luck there.

    I have the GA-945P-S3(rev. 1.0) motherboard, and the memory is OCZ DDRII, 667 mhz. I run Windows Vista 64.

    Anyone heard of this before?

    You don't have a memory problem. 32 bit Windows only recognizes 3.2gigs of memory, which you are probably running Windows XP. 64 bit Windows will recognize all 4 gigs.

      Yes 32 bit Windows only recognizes 3.2gigs of memory.
      If you want use your system with 4GB memory, you need OS and BIOS support.

      You can get some information here

        I run Vista 64. Also, the bios only acknowledges 3,25 GB, so does that mean that my motherboard doesn't support 4gig? I have the newest bios.

          Yes indeed. Your MB or your Bios must support it. I has something to do with memory adressing. On some Bioses you find a setting called "memory hole remapping" or something like that. Sorry i'm not very technical in english. Take a look on your bios if you find something like that. If Not, than i think it won't support it.
