you control the ratio...by changing your FSB and RAM speed...as this is where it is determined..example FSB=200 RAM speed 1600...you divide 1600 by 2 ...that gives you 800...so FSB-->DRAM ratio is 200:800 you reduce that to lowest term and it is 1:4 FSB-->DRAM ratio...
Hey, Thanks for the replay
I searched the bios and couldn't find an option to change the RAM SPEED,
I can only change the Voltage and the timings. How does it called ?
