If you were to tell us your mobo we might be more specific in our answer.
Some mobo run at 400 with 1 stick of ram and at 333 with 2 sticks of ram.
on some mobo you have to enter the bios and change settings for 2 stick to
run at the same speed.
Read you mobo manual and see what it says about RAM placement and type
thereof.
