It is a bios setting that allows you to run the memory at a asynchronous speed. In other words a different speed than the cpu's fsb is running.

OK that makes sence, but not all the way, ok for exaple a value of 5:3, or 3:5 whatever that setting is lol, what would a AMD XP1800 be running at, i think its a 266mhz, but i dont know if that doubles or anything, and what would the RAM be running at?

Thanks for your pateice with the dumb kid...

Amd 266 cpu's run at a fsb of 133mhz. The 3 would be the cpu's fsb and the 5 would be the memory. divide 133 by 3 =44.3. Then multiply 44.3 x 5 =221mhz or 442ddr.

So i am guessing the use of this setting is to make it so you can overclock your RAM without messing with your CPU, right? And then the lower you set the first number and the higher you set the second number the more of an overclock you will get on your RAM, and i also assume that there is no effect on the CPU speed correct, Thanks again!
