what will happen if i use DDR3 and DDR2 RAM simultaneously?

Question

What will happen if i use DDR3 and DDR2 RAM simultaneously on a single motherboard that suports both? Will the motherboard and Ram get damaged? Also, what will be the result of using DDR2 Ram in DDR3 slot and vice versa. Won't try such things though. Asking out of curiosity

Answer 1

Its Simple - You cant.

The motherboard will refuse to power on at best, or fry the ram at worst.

What mobo supports both anyway ?

Answer 2

The slots are incompatible, so you can't put DDR2 Memory in a DDR3 Slot, or vice versa. If your MB support both, as some do, then you'll have to consult the MB Documentation to know if you can use both at the same time (most do, not all).

Answer 3

I wouldn't recommend it, even if you have an uber special motherboard that will support mixed ram.

Answer 4
