I'm building a system with a P67 motherboard and planning on getting an i5-2400 processor and some DDR3-1600 memory. Looking at this chart: wikipedia chart, it says the i5-2400 only supports up to DDR3-1333. What does that mean? Will the DDR3-1600 memory still work, just at 1333 speeds?

Yes. On most socket 1155 boards, 1600 ram will run fine and permit you to overclock the cpu. Try changing the cpu fsb up by 20% with the memory settting in manual and the memory fsb at 1333. Use cpuz to confirm the actual ram speed, which will read as 800 for 1600 ram.

imo using an i5 2400 and a p67 motherboard will be a waste.
p67 is better used with an oc'able cpu e.g. a i5 2500k or i7 2600k or i7 2700k.
2400 is not oc'able (may be you can get a few mhz out but it's cpu multiplier is locked) so it'll work better with an h67 motherboard or a z68 motherboard.

The last poster is correct, but it won't hurt to run 1600 ram; I go for the lowest price after rebate on 1.5v 8 gb kits.

Well now I'm kind of sorry I didn't ask before I bought the motherboard :)  . Those other processors are out of my price range. I'm really not too concerned with overclocking though, so I think my choice will be fine.
