In the bios, if I set my CPU=300(default=200), does that mean my memory controller is operating at 300 mhz and is it faster this way with my memory set to ddr266 divider and run my ram at 200 mhz at 2-2-2-5 or should I set my cpu=200 and raise my memory to 266 mhz with 1:1 divider and relax the timings?
