I have a crappy mobo that I plan to upgrade soon, but my question is, my mobo only supports up tp pc2100. I want to upgrade my ram first and I was thinking about pc3200. Will it work in my current mobo and only operate at pc2100 speed, or not work at all? Also, I was thinking about A7N8X-Deluxe, but I am also confused about ram steppings or timings. What is the timing for this board?
