you're post says 12.5x 205, but your cpuz says 12x 205, which one is it?

I would leave the multi at stock and go from there

set ram timings to auto. you wanna lock your ram speed as well, but I don't know the Intel settings for that.

if that works, then get the cpu speed where you want it, and if it's stable, start messing with ram settings

You could try 12.5x266 and set your ram/fsb ratio to 2:3. That should get you 3.3Ghz without having to give the cpu much more than 1.2v. Then you could keep the ram at 800mhz. Make sure the ram is at the default timings and voltages.

So if you set the voltage for the cpu to 1.3 and the ram to 2.1 then slightly increase the FSB speed what happens?

put the fsb:dram ratio to 1:1 just to rule out RAM.also try 205 and higher with 12 multi and see if that works.
