Is it possible to put or combine DDR3 2GB and DDR2 2GB in a same supporting board
i had this Asrock H61M VS3 Board that supports DDR2 and DDR3
Like all the other posts my answer is the same.
Firstly, your motherboard doesn't have a DDR2 slot so there is no way you can install DDR2 and it will not fit in a DDR3 slot.
I had a motherboard which supported both DDR2 and DDR3- ASUS P5G41C - M LX. However, from theory and from my own experience I know that you can install only one of them, both will not work together.
