    Help: Cannot Add Memory


        Hi, I have a Desktop Board DX48BT2 in my custom built video editing workstation. I just updated this computer to Windows 7 Ultimate 64bit. It “was” originally built as a 32bit Windows XP Pro system in the following configuration;


      OS:  32bit Windows XP Pro Service Pack 3 (build 2600)


      3.00 gigahertz Intel Core2 Extreme                   

      64 kilobyte primary memory cache                   

      6144 kilobyte secondary memory cache 

      Hard Drive 1: Samsung HD103UJ 1TB SATA2 7200rpm 32MB

      Hard Drive 2: (2 x 750GB)Samsung HD753LJ 750GB SATA2 7200rpm 32MB Raid 0

      Hard Drive 3: (2 x 750GB)Samsung HD753LJ 750GB SATA2 7200rpm 32MB Raid 0

      Main Circuit Board:

      Intel Corporation DX48BT2 AAE26191-204                              

      Serial Number: BQBQ815000JG                              

      Bus Clock: 333 megahertz                             

      BIOS: Intel Corp. BTX3810J.86A.1521.2008.0318.1426 03/18/2008

      Memory Modules:

      Memory - 4GB (2x2GB) PC10600 DDR3 1333 Dual                              

      3324 Megabytes Installed Memory                              

      Slot 'J6H1' has 2048 MB                             

      Slot 'J6H2' is Empty                             

      Slot 'J6J1' has 2048 MB                              

      Slot 'J6J2' is Empty  


        As I stated, I went to Windows 7 64bit. I did a full custom install wiping out Windows XP Pro. I left all my other components intact which showed everything compatible with Windows 7 64bit. After installing Windows 7, I added 4GB (2x2GB) PC10600 DDR3 1333 Dual Memory. I used the exact type/brand giving the system a total 8gb. The memory was recognized upon boot up. I then installed Microsoft Office Professional 2007 64bit which installed fine. I then proceeded to open up Word in Office and all was ok. I continued on to open Access at which point the screen went black and the computer rebooted and asked me to restart Windows in either Safe Mode or Normal. I opened in Normal Mode. I then went back to opening and closing Office 2007 seemed ok, but then the same thing happened again. Once rebooted, I tried to install my editing program (Vegas Pro 9 64bit). It was almost installed and once again, the above happened again. This process happened randomly at least eight times. I thought that maybe one of the memory sticks were bad, therefore I purchased another two sticks and still received the same results as before.

        At this point, I removed the memory I added turning the system back to just 4gb. Since then, I installed several programs, opened/closed and used them “flawlessly” without the computer shutting down on me.      

        I “did not” do any BIOS or Motherboard changes and/or updates. Could you tell me if this is why I’m having trouble adding the additional 4gb of memory? If so, could you point me in the right direction for the “correct” updates? Keep in mind, I went from 32bit to 64bit. Your help would be most appreciated. Thank you in advance, Ray Sherman
