Isn't 1:1 considered standard? And I'm not sure what you mean by "favors the RAM." In this case, you're trying to lower the speed of the RAM, compared to the FSB.
I don't know if some motherboards are entirely incapable of them, but there should be dividers as low as 5:4 or 3:2. with a 5:4 divider, you could get 3.5Ghz on the E6300 with 400Mhz RAM. 4Ghz could be achieved with 457Mhz memory, DDR2-914. Not extremely common, but more so than a 4Ghz E6300.
@ Nagasama; The 1:1 being more favorable is indeed true, and is still present in the Core 2 Duos. The lack of an Integrated Memory Controller (IMC) on the CPU die means that the memory is not in perfect sync with the CPU as it is in AMD's K8 systems. With AMD, you could change the dividers around and you wouldn't see any performance loss except for that from possibly slower-running memory. With Intel processors, its not quite as favorable.
It used to be a big deal, and everybody was encouraged to steer away from not using a 1:1 ratio, but I believe Anandtech did some testing that showed that the performance loss from something other than a 1:1 ratio was not significant. Atleast, not significant enough to be a deterrent to the higher speeds gained through overclocking. I've never been able to find where they did the testing, but apparently some really influential people are convinced that the performance loss isn't significant.
