Guys am confused,

Some on the board adviced me to tighten my timings, as in lowering
the timings and in the divider 1:1. They are now at 1150mhz 5-5-5-15.
My Q6600 is curently at 3333Mhz the divider is at 2:3 according to CPUz.

Tightening meaning, lowering the timings as also the speed in order
to get 1:1. Wich means making them slower in mhz but faster in
timing.

What is the difference and what is better? Where can you notice that
performance difference in practice other then in benchmarking. Wich
I don't care for if it is really minimal.

Thx
