At 3.2ghz you would need ram that could do 458mhz and those on average will do at least DDR2-950 so don't worry. You may not have the tightest timings in the world but timings don't matter that much at all in an Intel system as long as you get your FSB.
I'm pretty sure I have read reviews of the NQ's hitting DDR2-1000 at 5-5-5-15 timings which is not bad for cheap ram.
