Installing addit. 2GB RAM - e1705/9400 32bit OS - is there any sense? (dual channel?)

Hi everyone

I posses a dell 9400/e1705. Currently I have 2GB of RAM installed (in one piece). I was thinking of installing an additional 2GB. I was wondering if there is any sense in doing so. First of all I have 32bit system, so the whole amount (4GB) will not be recognized. Secondly I am unsure if I will notice any increasement in performance. I mainly use the computer for photo retouch in Photoshop (I operate on big RAW files) and sometimes I install games.

A friend of mine said this would a good idea beacause even though the system will not see 4GB the chipset will allow the two memories to work in dual channel (If i were to add just 1GB I would have a total of 3GB but no dual channel).

Can anyone give me any advice?
Let me just add that I do not have a 64bit CPU so I cannot change my OS.

Big thanks in advance
Simon

 

Some computers have what is called flex mode:

It is a combination of both single channel and dual channel.

 

thanks for the reply.
