If the motherboard has an nForce chipset? Of course that'd be a big mistake.
Now, if the motherboard comes with an Intel chipset? Of course it can take it w/o a glitch.
A board with an Intel chipset can take mixed RAM, just as long as it works. DDR2 667 will work with DDR2 675 just fine and one can mix DDR2 667 with DDR2 800. Though that will never happen with an nForce based motherboard.
I did it with my XMS2 675 and HZ 800.

Now, that will happen and the default RATIO will be a 1:1 and the system will definitely be able to overclock, but maybe a max of 350mhz will be. Depending on how good is the 533mhz kit.
