Latitude D620 RAM Limitation in BIOs?

  • Hi Guys,
     
    I currently have 3GB RAM in my laptop in the following configuration:
     
    2GB 667MHz Stick
    1GB 533MHz stick
     
    I am thinking of replacing the 1GB stick for a 667MHz stick, so that the frequency of all my RAM is the same. Since work are paying of rmy upgrade I am looking at a second 2GB 667MHz stick, to bring my system total up to 4GB.
     
    I went for the 2GB since I understand that having the same size sticks of RAM, running at the same frequency, equals a performance increase since DCI turns itself on? Is this correct?
     
    Also I am running Windows Vista 32-bit and have the latest Bios updates (I think it was A08). If I go ahead, will my system see the entire 4GB, or only 3Gb still?
     
    I have been informed that even if the system only see's 3GB I should still go ahead so that the system can run in DCI mode? What would you suggest?
     
    Thanks.

  • Ok I have just upgraded to 4GB RAM, but the BIOs only recognises 3327MB.
    Why is this? Will Dell be releasing a BIOs update to address this issue?
    They stated my machine was capable of 4GB....
  • Same problem, installed 2 2G dimms in my D620 and the BIOS only makes 3327 MB available.
  • Its just a limitiation of 32bit OS's Im afraid - nothing you can really do.
    At least you have a matched pair so should get a performace increase ;)
     
    Im selling the laptop now - to make way for my max spec'd XPS M1730 ;)
