Why Fujitsu Siemens LT not showing all RAM?

Jacques.Gordon
I have a fujitsu siemens pro V2030D with 2 x 1GB memory sticks installed but the BIOS and windows XP only see 1GB but CPUz sees both.

Does anyone have any ideas how to get both recognized by the BIOS and windows?

CPUz extract:

    And it's not a result of fitting new RAM. If that's the case you need to test the RAM with a testing Utility.

    You could start off by downloading the Ultimate Boot CD which is free here

    http://www.ultimatebootcd.com/download.html

    Then burn to a CD and load into your system and boot off it. Using the Arrow Keys Highlight Memory and chose one of the Testing Utilities and test the RAM

    If you get errors remove 1 RAM Module and retest. If that's fine remove the existing RAM Module and fit the one removed and test again.

    If both pass the test you have a Timing Issue between the different RAM Modules. Of course if one fails it needs replacing.

    If this is newly fitted RAM it sounds as if it's the wrong type for this system look here for the correct type you should be using.
