RAM Dual Channel Issues
I currently have an older Gigabyte Mobo, but plan to make a new system when I have the money. What im basically doing is buying things for this system that can also be used in the new system. For instance I was going to buy 2GB Dual Channel RAM for my current mobo (new one has the same PC and Pin) and then put it in my new system when the time comes. I dont think 2GB is necessary for me right now because of my current CPU (xp2500) in my current system. What I want to do is buy a 1GB (512x2) set and then later buy another set to put into my new system to get my 2GB. The point is to get the 1GB now for my current system and use it now lol. One thing that is the problem with my current mobo is the manual says I can't fill all 4 slots and get dual channel, whats up with that? I have 512 (256x2) right now and I wanted to put the 2 512's in and put the other two 256's in the remaining slots to have 1.5GB. Why would I not be able to get dual channel in my mobo if I fill the slots. If it does run single channel, what performance decrease will I see, expecially in games like BF2. Is the full slots, no dual channel common in current mobos? Someone please give me some advice.
