I am new here first some details.

OS: windows vista home premium 32 bit(Japanese)
Computer: Dell XPS M1530
Memory 2GB + 2GB (2GB PC2-6400-6, 200 Pin, SODIMM)

Question:
When I use task manager Performance it shows Memory 2045
Also attaching screen shot of CPU-Z. Why it won't show 4GB memory?
In Vista forum I was advised to run memory test from this site and
I do not know how to run memory test?

Any help, advice or suggestion will be appreciated in this regard.

PS* In the computer there was 2GB memory, later purchased 2GBx2 as mentioned above
from Dell Japan.

A 32 bit OS will only utilize 3.5 gigs at best. Most likely since it is 2 x 2 gig modules it only identifies one.
Right click on My Computer and then click on Properties
What does it show for total memory there?

Thank you very much for quick reply.

After posting my question I removed the DIMM A and B Memory Module then using
air blower(rubber not can)cleaned the module edge connecter and re-install
B and A Memory.
Now it is showing 4GB.
I also applied your method, My computer/Properties it is showing 4GB memory.

Thank you once again.

OK cool but remember the OS can only use 3.5 gigs total as it is only a 32 bit OS. To get use of all 4 gigs you would have to have a 64 bit OS. :thumbsup:
I am glad to hear it was a simple fix though. Good job finding it on your part. :notworthy:
