How to manually set DDR3 1600 with P67 chipset

[sleepybp]

Need some help please. I just setup a new i5-2500k build with msi p67 GD55 motherboard and Corsair DDR3 1600 1.65V. My ram is automatically running at the default 1033ish speed. What memory multiplier do I need to get to 1600? I believe these new processors run at 100mhz base clock. So does that mean i need to set memory multiplier of 16 for DDR3 1600? Also my memory is running around 1.5v auto and my motherboard only allows small adjustments which would put me up to 1.644 or 1.653 or so. If my ram is rated for 1.65v at 1600 what would you guys recommend? Thanks guys,

BP

WHen you change the memory divider it shoudl tell you on that same screen what speed you RAM will not be running at. Either 1.644 or 1.653 is fine. I woudl choose the slightly higher one. Dont forget you will also need to manually set the timings.
