Hey, I have 4 GB of DDR2 RAM. Two of the sticks are G Skill intl and are both clocked at 800 mhz. The other two sticks are corsair and are clocked at 1066 mhz. But when looking at amd overdrive, they're all only running at 400 mhz. How do I fix this?

You don't its suppose to do that. When you put them in dual channel, they cut their clock speeds in half and synchronize. You get more performance so don't worry about that. And also when you mix ram of different frequencies, the motherboard under clocks the faster ram to match the slower ones. A rookie mistake.
 


Well, thats just a little off base, but DDR memory does actually run at half its "advertised" speed.
They advertise it at the double data rate numbers for selling purposes, because bigger numbers look more impressive to a potential buyer.
