Increase the size of usable memory Windows 7 32-bit OS

[harishgogoi]

I've increase the size of my RAM to 6GB (2GB+4GB DDR3 1066MHz) in my Samsung RV509-AOCIN laptop which has expandable memory upto 8GB.
Now, the problem is that Windows 7 Ultimate 32-bit OS use only 3.43GB of the memory . Is their any way I can use the total 6GB of my RAM in the same OS.

You have to use 64bit OS in order to utilize more than 4GB RAM.

AFAIK You can't do that. Get the 64bit version to use more than 4gb (actually 3.5 gb)

^^ As told above, system wont use >4GB in x86 mode.
Thats why i've upgraded to x64 recently.

Here is the official word from Microsoft, detailing each.

No Way..Reinstall the OS with 64 bit version.
