Firstly I'm new at this. Not a very computer-ish person. So I very much apologize if this is not the right place, but here it goes..
My Motherboard is an Asus P5LD2-SE. I'm running in Win 7 Ultimate 32-bit(x86) OS, 1GB RAM (2x512 MB).
I'm planning to upgrade my OS to 64-bit and because I know my Motherboard is a dual-channel, I bought a dual-channel 2 GB RAM (2 pcs). Am I still able use my old RAM ones, since it is 4 slots? Which in the end will show 5GB. Is it possible?
