It's already doing 333MHz. It's Dual Data Rate memory.
Times that 166 by 2 and see what you get ;)

Yes. But there's another reason than overclocking to alter the BIOS settings for RAM.
If the RAM modules were, say, PC3200 400MHz ones, then the best procedure to follow would be to set things up to be identified automatically as you've suggented, to have RAM timings operating in accordance with the manufacturer's specifications. But then you'd be best to go back and change the RAM SPEED so that it was actually running at 333MHz, rather than the 400MHz it's capable of.
Sound silly? It's not. The system works best when the RAM is running 'in sync' with the processor's bus speed. Run your RAM at a faster speed than the front side bus of the processor, and your CPU will sit there confused a fair bit of the time, like a kid who's trying to get the timing right to jump onto the playground roundabout! The end result will be that your overall system will be slowed down by the faster RAM, not speeded up.
The speed you should have your RAM running at is the speed of your processor's front side bus, and if you need to change the settings to 'Manual' to do so, then you should.
