DDR2-533 on 667/800 Mobo (EDIT: Please ignore this thread.)

Title says it all.
I have a couple of old DDR2-533 sticks of ram, and I'm wondering if I could use some on my system. The thing is, my motherboard supports DDR2-667/800 speeds. This is my motherboard

Specs say no, but why don't you try it out anyway? Worst case scenario - a few beeps on the mobo, cut the power, take them out and back to the way it was.
