how to change memory timing??

[dirty_pants]

hi all, just a quick question..how do you change the memory timings??
Have 2x2gb 1066 ocz sticks in at the mo..already altered the volts to 2.1 in the bios as stated by the manufactor but the timings given should be 5-5-5-18 mines showing up in cpuz as 5-5-5-15???? had a look in the bios settings and managed to set the frequency to 1066 and ganged mode but this has got me stumped theres just too many bloody numbers to change!!!
Have an asus m3a79-t delux mobo.
i'm new to this o/c stuff so a bit of a tentative approach is the route im going to start with!!
cheers

lucky u, 5-5-5-15 is better anyway mate, lower the better for timings

the speed it is at just now is alightly faster, what slow it down if your not having any erros/problems.?

you also change that in the BIOS mate.
