eh I'm gonna run 1:1

what inspires people to do 4:3 2:3 or whatever?

also in a #:# ratio does that mean FSB: DRAM or DRAM:FSB???

Usually it FSB:RAM

I run at 2:3 because it is harder on my mobo to hit 400x8 than 356x9.

Also this way my ram runs at DDR2 890 rather than DDR2 800.

More memory bandwidth. Your memory bandwidth does not saturate the FSB until a 1:2 (FSBRAM) ratio.

That something you're going to have to find out on your own. Either way we're talking 1 - 2fps, very minor real world differences.

Usually you want the highest speed possible without going over 5/5/5/15 timings.

Could I do the same thing my way? Just take my 800 set and OC it to 1200? lol
A good set of PC6400 (800mhz) can run at 1200mhz, for example my set of ram. I also have a set of Crucial Ballistix Tracer PC6400 that can also hit 1200mhz.

Here are the ram speed options that my P5K gives me for my current FSB. Pretty high. I know my DDR 2 wont ever see them but I don't think the mobos coming out will be the limiting factor so much any more.
