I have an MSI motherboard: K9N6PGM2-V2. This motherboard has 2 DIMMs sockets for DDR2-RAMs. But it's stated in MSI website that it supports up to 8GB RAM

Main Memory
- Supports Dual Channel DDR2 667/800
- 2 DDR2 DIMMs (240pin / 1.8V)
- Supports a maximum memory size up to 8GB.

How could this be, if the DDR2 cards are of maximum of 2GBs. That means 2x2GB RAM which is 4GB maximum? Can anyone explain to me ?

This question came from our site for electronics and electrical engineering professionals, students, and enthusiasts.

Motherboards also sometimes support more memory than what is then possible. For example, the Asus' P67 line supports 32GB, but I couldn't find anyone that manufactured 16GB DDR3 sticks when it was new, 2 months ago. – tyblu Apr 22 '11 at 23:31

4Gb DDR2 sticks are available(but quite expensive) and there are even bigger server ones.

Up to 8gb on Crucial. :) – Dean Apr 22 '11 at 21:18
Thanks @BarsMonster, I didn't find 4GB DDR2 sticks in Egypt that's why i expected there are no 4GB DDR2 sticks ! – Ashraf Bashir Apr 22 '11 at 21:25
