If you are running at 2:3 that means that your memory multi is 2.5 right now, which is perfectly fine. Don't get hung up on running 1:1 memory:fsb. Just let your memory run at its stated speed unless you are overclocking the cpu.
It means my memory multi is running at 2.5? I don't understand since 266 x 2.5 = 665. My memory multi running at 3.0 makes more sense since 266 x 3 = about 800ish
