you seem to be saying that my (32bit system) can only 'see' about 3GB - 3.5GB?
so what i am asking is this ... would i be wasting my money if i bought another 2 sticks of 2GB Ram, or maybe 2 x 4GB sticks, for the empty slots. would i still only be able to use 3GB and the rest be wasted ?
If you don't consider the loss of 512mb it wouldn't all be such a waste. It's best to have all RAM modules of the same size, same brand, same speed and latency ('matched' pairs). If you have an older motherboard, it might not recognize a larger module. You would need to check a compatibility chart for that board to make sure the RAM modules would be recognized. For example, some motherboards may only recognize a 512mb module as the largest, and only of a certain speed. Some motherboards are even picky about the brands of memory they can use. Motherboards are rather cheap. You can get a newer motherboard for under $100 dollars, 8gb of memory for $50, and a processor for anywhere between $60 to $200 that would be capable of a 64-bit OS.
