Hello everyone. I was hoping you could help with a question I have. First, here are my specs: Motherboard: ASUS P5K SE RAM: 2x1GB OCZ DDR2 PC2-6400 (PN OCZ2P800R22GK) CPU: Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40 GHz Video Card: NVIDIA GeForce 8500 GT O/S: Win XP Pro SP3 32-bit I'm looking to upgrade my RAM. It looks like I have 4 slots. My questions are: 1) What is the maximum I can put in there? 2) Can I add RAM alongside the ones I already have, or do I need to replace them? 3) What is the best kind of RAM to get for that motherboard? Thanks in advance.
