I have 1 GIG of RAM, Two 512 sticks. I Just added One 1 GIG Stick, My
system only shows 1.5 Gig, Why? I checked my RAM It's all good. Maybe, do
I have to get another 1Gig for the last bank? Do I have to install them in
pairs? But I tried each stick in my system by themselves and my system show
the correct memory size.

According to the manual for your motherboard, if you are using single
channel sticks you can use 2 sticks which must go in DIMM slots 1 and 3.

If you are using dual channel sticks they must be matched pairs (maximum
of two pairs), a matched pair going in DIMM slot 1 and 2 or 3 and 4.

Quote:
To reach the performance of Dual Channel DDR, the following rules must
be obeyed:
When installing TWO DIMM modules: Install DIMM modules of the same type
and size for slots [DIMM1]+[DIMM2] or slots [DIMM3]+[DIMM4].
When installing FOUR DIMM modules: Install DIMM modules of the same type
and size for slots [DIMM1]+[DIMM2], and slots [DIMM3]+[DIMM4].

I suspect you have single channel sticks and only the contents slots 1
and 3 are being recognised.
