So I've been testing overclocks with my Intel E5300 with 2GB DDR2 800mhz RAM. When I came to a point where I couldn't pass fsb of 250 x13. This was 3.27ghz. I dropped my RAM Frequency from Auto to 667mhz and it let me overclock further. But now the ratio is 5:6. With which reading tells me 1:1 is what I should be aiming for..? How do I go about overclocking further while keeping my RAM ratio in the right range? Theres only options for Auto 667mhz and 800mhz.
