M Kiewitz: I hacked on your function, dimming the variables, removing the MB so that it just returns a number, and adding the option for checking remote pcs. Once everyone has tested this, you might consider adding your function to the UDF forum.

Code:
 

FUNCTION GETCOMPUTERMEMORY (optional $target) 

  Dim $Basekey,$RAMTranslated

  If $Target <> ''

    $Target = IIf(Left($Target, 2) <> '\\', '\\' + $Target, $Target)

    $Target = IIf(Right($Target, 1) <> '\', $Target + '\', $Target)

  EndIf

  $BaseKey =$target + "HKEY_LOCAL_MACHINE\Hardware\ResourceMap\System Resources\Physical Memory" 

  $RAMTranslated = RIGHT(READVALUE($BaseKey, ".Translated"), 8) 

  IF @ERROR=0 

    $GetComputerMemory = (VAL("&"+RIGHT($RAMTranslated,2)+SUBSTR($RAMTranslated,5,2))+250+16)/16 

    IF ($GetComputerMemory mod 2)=1 

      $GetComputerMemory = $GetComputerMemory+1 

    ENDIF 

  ENDIF 

ENDFUNCTION
