termination voltage?

In my bios setup theres an option for termination voltage. My ops are auto, 1.27, and 1.29. What is this? Does it have any effect on overclocking?

thanks

good question, i would like to know that too

I looked all around the web today and no one really knows. Apparently its only an option on MSI KT400 boards. All the reviews say its an option but none explain. Most admit to having no clue what it is. None of the BIOS optimization guides say either.

Ill get around to experimenting eventually, but id like to hear it from you guys first.
