How do you read the CPU/MEM dividers?

Can someone tell me how to read the 5/4, 3/4, etc for the CPU/DDR divider.

I know that 1/1 means that the FSB on the CPU and the FSB on the memory is equal (e.g. 200FSB on the CPU = 200FSB on the memory). Does 5/4 mean that the FSB on the DDR is set 1.25x faster than the CPU ... or the other way around? Please clarify. Thank you!

Other way around... divide the first number into the second number for your "ratio multiplier".

3/4=1.33X
4/5=1.25X
1:1=1X
5:4=0.8X
3:2=0.66X

FSBX"ratio multiplier"X2=DDR speed

Thanks Batboy!

I get it now. You are just increasing the FSB on the CPU while trying to keep the DDR FSB to stay within specs. Thanks!
