Hello Friends - Need a help

[digitalsujatha]

I had 4 GB RAM DESKTOP PC DELL OPTIPLEX 7010 Model.
RAM Specifications: Hynix KOREA 08
4 GB DDR3 2Rx8 PC3 10600U 9 11 B1
HMT 351u6CFR*C - H9 No AA 1143

I use Windows 7 32-bit OS

Today i added additional 4 GB RAM. The new RAM specifications are
Hynix 4GB RAM DDR3 10600 Mhz
Hmt3256cfr8apbnoaa1710.
I just installed the RAM.
Any other settings needed
It shows System Memory is 8 GB(3.41GB Usable).
My questions is, does the system use the full 8 GB or using only 4 GB?
Or have i installed it completely perfectly correct or any more settings needed?
Kindly pls help me with the above query.

Thanks & regards
K.Sujatha

You use a 32-bit OS.

A 32-bit OS can't use more than 3.4....GB of RAM.

You must install a 64bit OS to use those extra RAM.
