So im not sure if i understand overclocking, I just want to check with you guys so i dont reck my rig. If i have a fsb of 400MHz and a multiplyer of 7 (400x7=2.8GHz for cpu) then i could run the ram in a 1:1 ratio where the ram would be 800MHz. Is this right
Help Overclocking ram and fsb

If you run the RAM 1:1, you can get up to 533fsb before the RAM is being overclocked too, giving an overclock of 3.7gHz with the ram on stock.
You'll likely find the processor gets annoyed and won't play ball before that, but if the CPU does make it, that's when you'll have to start running different ratios.

The benifit of a 1:1 ratio is that it is easier for the motherboard to run stable, as it does not have to synthesize an extra clock for the memory, when overclocking my asus p5n-e sli, setting the memory to 1:1 allowed me to reach a higher fsb, due to the increased motherboard stability.
Additionally, due to the architecture of s775 systems, you do not gain much performance ofer 1:1 due to the fsb becoming the main bottleneck.
Depending on how your motherboard behaves it may be easier to use a memory multipler or drop the multiplyer of your cpu to achieve higher fsb and memoryy clocks.
To be honest each computer setup is different, not all chips are created equal, and you need to experiment to find the max overclock you can achieve.
First, you need to find the max fsb of the motherboard, deduce the cpu multi and the ram to 1:1 and raise the fsb till you find the top limit.
second, find the max ram speed, increase the ram multi and raise till your computer becomes unstable
third drop the ram to 1:1 again increase the cpu multipler to max and raise the fsb till you find the max oc for the cpu
fourtch, armed with this information, try different combinations of multiplers for ram and cpu to get the max ram, fsb and cpu frequency possible
you can use something like orthos for stability checks
