increase working memory (4x Swissbit) from 3GB to 4 GB by replacing the 2x 512 MB - what memory can I use

Increase working memory:

my son’s computer (Desktop Medion 32 Bit) has 3GB memory and I would like to increase that to 4 GB.

It has 2x sets of: 1x 1GB PC2-5300U-555 MEU12864D4BC1EP-3DR and 1x 512MB MEUO6464D4BJ1EP-3DR.

The memory is pretty expensive (in Germany at least) so I would like to know what kinds of memory can I replace the 2x 512MB with? Do I need exactly the same memory number as the 2x GB? Or what other numbers/types could I use?

I have no knowledge in this area and get confused by all this different numbers and details.

Computer system is Windows Vista 32x, so it loses some memory to Vista

  1. You need to find the motherboard's website and the approved memory list
  2. the 4 will never be usable by the 32bit opsys. if you put 4 in it will make it something like 3.25gigs. not really cost effective.

    the ram......... if you can get the same exact ram buy it. same brand/speed/voltage/timings. or just buy 2 2gig sticks of the same stuff. ( speed/voltage/)....... or look up the specs on the motherboard and buy 2 2gig sticks of the fastest stuff the board supports.

    64bit operating systems are the way to go.
  3. I think the motherboard is: 06/20/2008 - Bearlake - 6A79OM4BC - 00

    But this does not tell me much - how do I use this to know which memory I can use?

    64bit: my son will have to manage with the 32bit for a while - if I could just increase the memory a little

    and (I think) the computer Medion MS 7502 (PC MT 7 MED MT 503)

    But if I understand swifty_morgan's answer right (not so easy for a dummy like me), if I increase to 4GB then I will only waste energy (have higher electric cost) with little or no gain - or have I understood wrong?

    no, a 32bit operating system will not utilize all 4gigs of ram. you need a 64bit operating system to utilize 4 or more. don't waste money on what you have.
