High FSB with Divider?

[Cashman]

I cannot seem to find a difference between having a High CPU FSB whilst using a divider (166 5:4) or simply using a 1:1 clock.

I know my RAM is good for 280 2.5-3-3-8 2.8v and 300+ 2.5-4-4-8 2.8v

However today I was playing about using Dividers but it doesnt make a great deal of difference in Super Pi or Sandra Mem Bandwidth. Yet to try 3dMark.

Anyone got any info on this that they have found?

Its an interesting point and one i have thought about a lot. And on systems with unlocked multi's you have that extra bit of flexability. imo, with overclocking its all about trying to get the most bandwidth from your Chip / mem. Everyone knows that high fsb, high multi and 1:1 equates to a fast system but each mobo / chip / mem combo has its strengths and weaknesses.

Mobo build quality is still very idiosyncratic (especially for us), so i think its a different game with each different board you buy.

I dont have that much exp with a64, can you drop the multi anymore? If you could then you could try getting they mem back to your 300+ with the 5:4 Divider and a v high fsb..

Theoretically performance should be the same
