What bios says

[Maximilian]

Hey. I have 2 sticks of 512 PC3200 RAM and these should run at DDR400 right? In bios it says memclock=auto and underneath it its set to DDR200. Should i put this up or is there a reason its set to DDR200?

The memory clock is 200mhz but because it is DDR Double Data Rate, it runs at twice the clock rate. It you went to overclock and raised the bios to 210, the memory would be running at 420.
