I have no idea about RAM... but running 1600mhz rated sticks @ 1666mhz shouldn't matter right?

The options in my BIOS go straight from 1333mhz to 1666mhz... whereas my memory is rated for 1600mhz in its optimum XMP profile.

The memory voltage is 1.5v as per usual... but that extra 66mhz isn't going to cause any issues right? I've never played/OC'd memory before, always just left it at the stock XMP profile.

XMP #29.0-9-9-24-41-2T @ 800 MHz (1.500 Volts)

Should be alright... right? Just checking smile.gif

It shoudl be ok. Try it and if it doesn't work then you can always go back and change the multiplier to 1600 yourself.

I'd say it'll be fine, like 70Mhz is only a small overclock, if the BIOS doesn't let you change the speed to 1600, and it isn't stable, just loosen out the RAM timing slightly and that should sort it out.
