ds3 + ram timmings

[the_box]

i have the ds3 board with Corsair 2GB DDR2 XMS2-6400C5 TwinX (2x1GB) rated at 5-5-5-12-T1 i am also running a 6400 cpu just need to know how to get the best or should i say optimal settings for the ram + how to change the setings in bios using f10 bios + will do my system and memory any harm if i set my ram timmings to the above rated for a prolonged period? ie 8 months or so.

thanks.

So lets say the mb is reporting timmings off 5-5-5-18-T3 and the memory is certified at 5-5-5-12-T1 so if i set it to the max certified speed over a prolonged period of time this would be fine?
