If I run my opteron 165 on 300fsb*9 and use a 6:5 it would make my ram 250fsb right? What if my ram happend to max out on fsb250 does it mean that I lose no ram performence or do I still lose some? I am not planning to achieve 2.7 it is just an example. Also the ram I will be using maxes out on 250 for real.

like i said 6/5 would run it at 360 and 5/6 will run it at 250
its RAM/FSB

generally.

the thing is that is just an estimate. to get the real number, you do:

CPU Multiplier / RAM Divider
Round up to the nearest 1
Total MHZ / that

For example,

9 / .833333333333333 = 10.8...
11
2700 / 11 = 245.5

so with a 5/6 divider at 2700mhz, your memory runs at 245.5mhz

I read that in the dfi street forums about how to find out the real speed but I didnt understand it completely so I came here. Also this speed is not to bad at all. Thanks for the help guys.
