Question What is XMP and how does it change memory settings to 1600?

Hi all!

I am just now starting a new build. I got a super deal on a Intel I5-750 GigaByte P55A-UD3 motherboard combo and now I am looking to purchase correct memory for it.

For some reason, the GigaByte P55A-UD3 motherboard has had some issues with various memory types and speeds.

I just read how many people are buying G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL and it is working but....

Several of the posters are saying this:

"This motherboard DOES NOT have a handy 12X multiplier. Surprise... XMP worked correctly in this case setting the memory to 1600..."

Well, my question is this:

What is XMP and how does it change memory settings to 1600?

And my last question, is there really that big of a difference between 1333, 1600, and 2000 memory?

I would really appreciate your thoughts on this matter.

I would like to purchase some good RAM but would like to make an educated decision.
