trying to overclock q6600

[gamerxx13]

I am trying to overclock my q6600. i have one problem, the motherboard i have gigabyte ds4 p35, has system memory muliplier which isnt 2.0, it only has 2.5 and above. so then my ram speed is always going so high and my ram cannot support it. why doesnt it have 2.0? im trying to get my ram speed to 667 but it always puts it at 1000. why is it doing this?
