If my motherboard supports ddr2 533/667/800 Rams?

Question

I just want to know if my motherboard supports ddr2 800/533/667 rams, and i have only 800 and 533, will it burn my motherboard if i put those 2 types of ram together??

Answer 1

Look at the web site of whichever company makes your motherboard and you'll find out what it supports.

If you put two RAM modules of different speeds it'll just run both of them at the speed of the slower module (which in practice isn't going to be matter much).
