FSB / DRAM Ratio Bios Setting

I have a MSI K7N2 mobo (not the delta) that has this option in the bios. I am assuming setting this FSB / DRAM ratio to 6/5 would let me run my processor at 200 FSB while keeping the system memory at 166.

Am I right here? What are the performance hits?

Im looking to get a 2600+mobile barton & overclock without having to buy new PC3200 ram. Im hitting the ceiling with a max multiplier of 13.

166x13 = 2.17 GHz, and I was hoping for 2.3-2.4GHz
 
There's no performance HIT provided the system can handle that. Worst case scenario, it becomes unstable and you need a lower FSB (good thing they have so many ratios to play with, eh?) Ideally, you want to max your memory most of all, THEN worry about the CPU, so try to get that memory at it's best there. Even if it turns unstable, you should still be able to get a higher FSB than 166 though you might have to tweak voltages a bit to get things right.
 
I have two sticks of Micron Crucial PC 2700, so I just might be able to get 175 out of them. Thanks
