Does this mean that DDR ram "clocks down" to whatever the
memory bus speed is, or only that DDR400 will run at
333?



It depends on the chipset. If the chipset only supports DDR333, then that's
what it will run at. DDR400 at DDR333 will be as fast as DDR333, so there's
really no compromise, if that's what happens. Many chipsets can run CPU and
RAM asynchronously, though. That is, your CPU can be 333 AND your RAM can
be DDR400, it doesn't necessarily have to be one or the other. -Dave
