You might not be able to. It depends on your motherboard's BIOS.
First thing you need to do is find out what your RAM is rated for. Micron chips are really easy to figure out because the speed is printed right on the chips.
Generally, this is a good guide:
8ns = PC100 CAS3
7.5ns = PC133 CAS3
7ns = PC133 CAS2
That's just a guide, since most times, good quality memory can run faster than it's spec'ed to.
As for changing how the system runs the memory, you need to determine if your BIOS allows you to configure that. On the motherboard I was using (Asus P3V4X), there was a memory option (called SDRAM Configuration) to determine the settings from the SPD or to set them manually. You'd need to check for a similar setting in your BIOS. If you're not sure about what you're doing, ask before you touch anything!
