Basically I got x2 512mb DDR400 sticks running but they are set at a frequency of 166mhz which is DDR333 speeds. I have agigabyte mobo and I'm unsure of how to change the frequency to 200 as I can't find the CPU/DDR clock ratio. I have unlocked the 'advanced' menu and have put the Timing mode on manual but I cannot find the option to put up the frequency. The mobo is a GA-K8NF-9.
