Mixing different RAM Sizes in One Computer

Can you install different sizes of RAM into a single motherboard and it will still work? Yes you can!
There a tiny tricks you will need:

1. Make sure you’re buying same speed/voltage/non-ECC sticks.
2. When installing them install them in this way:   || Slot#1:[1GB+512Mb] || Slot#2:[1GB+512Mb] ||

I tried to install them in other order but all my tries have failed. The only thing that worked is installing them in the order I mentioned above.

~ Happy upgrading.
