Question About Manually Setting Timings.

Hi, I'm not a guru with computers. I know a fair amount, but one thing that is fairly new to me are timings. I never needed to set them for what ever reason till now.

I have these : G.Skill RipJaws (2GBx2) DDR3-1600 (PC3 12800) F3-12800CL9Q-8GBRL.
With this Mobo : ASUS M4A79XTD EVO

When I put my machine together the timings were set correctly but they were running at 1333MHz.
So I manually set it to 1600Mhz(Later realized that I needed to set the timings too since auto makes them way off..)

So my question is that, leave everything else auto and just change CL, tRCD, tRP to 9; tRAS to 24; and CR to 2T? What about tRC? according to CPU-Z it is at 40. I'm amusing that is way off?

Bare in mind I have no idea what all these mean... What ever forums I have read said to change the timing to what they are supposed to be manually.. but no one mentioned any of the other functions including tRC. I'm just assuming its somehow important due to the fact it is in CPU-Z?

PS: I thought It would make sense to Manually put the voltage to the rated 1.5v. Thought maybe leaving it auto would either lower or raise it for whatever reason.

    Welcome to Tom's Hardware!

    You only adjust the timings listed on the actual memory stick (timings, voltage & MHz). The other timings listed within the BIOS are set & maintained at Auto.

    That's all I needed to know :)
