  2. Did you try msconfig?
  3. no but will try thank you
  4. Taken from Microsoft help:

    If you add more memory to the system, it is possible that the BIOS will recognize the full amount of physical RAM that is installed in the server but that Windows will recognize only a part of the RAM. If the server has a redundant memory feature or a memory mirroring feature that is enabled, the full complement of memory may not be visible to Windows. Redundant memory provides the system with a failover memory bank when a memory bank fails. Memory mirroring splits the memory banks into a mirrored set. Both features are enabled or disabled in the BIOS and cannot be accessed through Windows. To modify the settings for these features, you may have to refer to the system user manual or the OEM Web site. Alternatively, you may have to contact the hardware vendor.

    For example, if you are running a system that has 4 GB of RAM installed and you then add 4 GB of additional RAM, Windows may recognize only 4 GB of physical memory or possibly 6 GB instead of the full 8 GB. The redundant memory feature or the memory mirroring feature may be enabled on the new memory banks without your knowledge. These symptoms are similar to the symptoms that occur when you do not add the /PAE switch to the Boot.ini file

  16. No trouble at all keith_32.
  17. Check for a bios update. I had a gigabyte board that wouldn't run with more than 4 gig of g'skill ram (board is rated for 16 gig max). They came out with a bios upodate that fixed it. The bios update simply stated better memory compatibility.

    2x1x2 = 4

    Are you sure you have 8GB of memory? Or did you buy 2x2G + 2x2G?
