My cossair 8500 mem was setup under my P5Q-E mobo with 5-5-5-18 timing, the memory itself is cable of and has been tested to 5-5-5-15 so i went into the bios and set the timing control to manual, it now shows as 5-5-5-15 in cpu z, what kind of affect does these timing settings have in games? an i go lower/better? i'm mainly a gamer so if this has no effect i'l just leave the setting's back on auto 5-5-5-18
