Why did you buy new ram?
If it's going alongside existing ram then just leave it set as is, though it's not really a good idea to mix ram like that.
If you are replacing the ram then you will need to change the settings in bios to get the best out of your new ram.
1600 is fairly easy if you have a bclk of 160 and ram set to 1604.
vcore about 1.2~ and obviously whatever voltage of the ram upto 1.65.
