What does this mean?

1. Support for DDR3 3000(O.C.) / 2933(O.C.) / 2800(O.C.) / 2666(O.C.) / 2600(O.C.) / 2500(O.C.) / 2400(O.C.) / 2200(O.C.) / 2133(O.C.) / 2000(O.C.) / 1866(O.C.) / 1800(O.C.) / 1600 / 1333 MHz memory modules

 

I'm looking at the UD3H Gigabyte motherboard right now and I see this.  Does this mean it will accept memory with those speeds or only overclock 1333/1600 sticks?

It will support all of those speeds if you do some overclocking. You can overclock a 2933mhz kit to 3000 if you wanted, it isn't just limited to 1600mhz kit overclocking 

[Fred Castellum]

Yup it'll only run at those speeds overclocked. 

[dragosudeki]

It will run those speeds overclocked, but its up to how good the RAM is to actually get that far. RAM that are faster to begin with are already tested to run stable at the speed.

If you think about getting 2133/1866 kit then you are fine. Ram will run 1600MHz at stock but you can just enable XMP profile and it turn speed boosts on No problem with same mobo and RipjawX 2133MHz 8gb.
