sorry i have no personal experience with the motherboard so i can't tell you if it supports it or not. what i can tell you is that memory dividers require hardware on the motherboard. so if your motherboard does not have that hardware then you can't get around it. if it does then there may be some software like clock generators, a way to unlock it in BIOS or a hacked BIOS version. if not then you are out of luck. unfortunately i would guess
that it probably does not have dividers given it is a fairly low end GigaByte board.
edit: i can now officially enter the ranks of those with way too much spare time
