The X6 multiplier is caused by SpeedStep throttling the CPU back during times of light CPU load. You can disable it by going into the BIOS and looking for something called EIST. Disable it.
Because I use Gigabyte motherboards (EP45's), I am unfamiliar with the BIOS options of the various Asus motherboards. Some of the Asus boards are good overclockers. Try your board first.
So here's my "standard" list of overclocking links. Use what you need.
This should be your first stop.

This should be your second stop. You need to know something about thermal management or you can fry your CPU. It's actually kind of difficult to fry a modern CPU, but it is possible.

Third stop will be a guide for your particular motherboard. Google is your friend.
For anything higher than about 3.0 GHz, you will need better cooling. Here are two under $50 heatsinks that are pretty popular:

Xigmatec Dark Knight

They both require a somewhat different approach to applying thermal compound.

And they are pretty large, so they might not fit inside your case.
And here's a good budget cooler:

Go through the first two threads. Do not do anything until you have a good idea about what you are trying to do. Once you have definite questions (you will, you will
![:) :)]()
), come back and ask.
Keep in mind that these are guides, not cookbooks. YMMV. Your Mileage May Vary. Because of all the variables, you may not do as well as someone else with a similar system. Or you might do better.
I am not a proponent of overclocking memory for Core2 systems. Many times, overclocked memory limits the CPU overclock - where the speed really comes from. Here's a thread discussing that:
