ddr 400mhz is 200mhz, same thing. double data rate of 200mhz is 400mhz, this is completely normal. you'll find that around here this is how it is expressed as well. no worrys. :)

DDR is just that. Double Data Rate. The actual speed of your RAM is 1/2 the DDR speed. DDR400 ie PC3200's actual speed on the bus is 200mhz. Nothing to fear. Everything is just fine.

Example. I am running my A64 at 255x10 = 2.55ghz. 255 is DDR510 because 255 x 2 = 510mhz

Understand now? :D
