That ram model you listed is not even 1.65v and 1.7-1.9 is DDR2 voltage. If you are trying to use ram at higher than 1.65v you either have fake DDR3 ram or you are misinformed and are going to destroy your ram.

It seems that 1.5 volts corresponds to 1333 and 1.65 for 1600..
Im a newb ok

If you are trying to buy that ram, don't bother, it's very old and requires ridiculous voltages for 1600. Nearly all DDR3 1600 modules sold in the last 5 years are 1.5v (standard ddr3 voltage.) Early DDR3 used high voltages because they were early designs. I wouldn't try using DDR3 ram that needs more than 1.65v at 2400.

If you have the ram, 1333 at 1.5v should be fine, but any other ram you mix with it will also operate at 1333 and 1.5v. You are better off not mixing such old ram with any newer modules, because it may not function at all and if it does work, it might be unstable. You also don't want to mix ram that functions at 1600 1.5-1.6v with modules that only work at 1600 with 1.7-1.9v. It's not too expensive to buy a used 2x4/2x8/4x4GB DDR3 1600 kit. New kits are usually double the price of used.

Are you looking to buy ram? Do you know the model of your motherboard? Nearly any DDR3 4GB kit will work with motherboards released in the last 10 years. If your motherboard supports 8GB modules and has 4 slots, you might want that instead if you need 32GB.
