MOBO : Intel G33 original
RAM : 3 X 1 GB DDR2 800MHz
+ 1 X 2 Gb DDR2 800MHz

my MOBO have 4 ram slots Dual channel.

can i fix 3 X 1 GB DDR2 800MHz + 1 X 2 Gb DDR2 800MHz in the four slots ... will it work???..
so that i can use a total ram of 5 GB...
???

also curren;y i have fixed 2 X 1 GB DDR2 800MHz + 1 X 2 Gb DDR2 800MHz in the 3 slots.. so that the total RAM is 4 Gb ...But my Win7 shows installed memory : 4Gb (3.24 usable)
Also i have a dedicated GPU Sapphire HD5670 1 Gb working fine...
why is the system not using the full 4Gb RAM. I have also checked in bios ... 4Gb is detected.
wht might be the problem??

Regards,
AH

Considering all the new hardware is now 64 bit I see really not much point in installing 32 bit unless really required by some old application

If you are using original windows OEM, then yes, 32bit & 64 bit OS have separate DVD.

And in that case, it will be clearly written on the DVD "this disc contains 64-bit software only" or otherwise.

If you have the original disc, they come bundled with 32 and 64 BIT.

yes if you got original one then there should be both 64bit and 32bit.in windows 7 64bit all the 32bit software work perfectly.its time to move to 64bit buddy.

OEM discs come with one type only. :)

64 bit has nothing to do with the rig except the ram which you have perfectly.
