I've heard that I should keep the ratio between my FSB speed and RAM speed at 1:1. But I'm not sure which number I should use to see if they are at 1:1.
I'm thinking about buying a Core 2 6400, which has FSB 1066. I can't seem to get a whole number how matter how I divide 1066 with DDR2-5300, which is at 667MHz or DDR2-6400, which is 800MHz.
What are the numbers that I should use to check if my CPU's FSB has a ratio of 1:1 with my RAM speed?

Well here is what you need to know. The FSB is quad pumped, meaning its actual speed is 1/4 of its listed speed, so for the Core 2 it would be 266Mhz. DDR2 is double pumped, meaning its actually speed is 1/2 of what is listed. So 667Mhz is actually 333Mhz, and 800Mhz is actually 400Mhz. So to run at 1:1, you would need 533Mhz, which is PC2-4200.
Now you actually don't have to run at 1:1, just make sure you run no slower than 1:1.

you are able to have the means to do it, its basically no longer advised as they might conflict. oftentimes regardless of the undeniable fact which you will get as quickly because of the fact the slowest speed you have because of the fact the faster ram can decelerate however the slower ram won't have the means to speed up. desire this helps.

If your ram capacity is I Megabyte the FSB !,1 Megabyte.

I've never heard of this before, if the motherboard supports the speeds of the RAM then I see no problem with using it.
