That's true, but the same thing happens if I use 2x1GB. Also, it posts at 390, but that doesn't make it stable. It hard-locks memtest. I need to work more on it, but I'd like to keep my 400FSB for 3.6GHz (nice round number). How much performance gain are we talking about going from 800 to 1000MHz with a divider?
