What Is The CPU VTT Voltage?

post #1 of 6
Thread Starter 
Is the "CPU VTT Voltage" that's found in my IP35 Pro's BIOS similar to the FSB overvoltage in a GA-P35-DS3L's BIOS?

+Rep for any help.

All I know is it needs to be semi close to your actual CPU voltage to be stable-er.

The CPU VTT is the CPU VolTage Termination. You can find some more info on that on a FAQ here.

Using this voltage in combination with the CPU VCore voltage setting can greatly enhance the system stability while overclocked. The system memory reference voltage is split between settings, the controller reference voltage and one option each for the two memory channels. In all cases, the base reference voltage can be set to a maximum of .03V over half of the set memory voltage. (Taken from HardOCP)
"In summary, the CPU VTT controls the CPU termination voltage. Based on Kirmie's observations, it reduces the number of false electrical signals by providing a form of "ground" to pull out these false currents. ." (Credit to Kirmie for the find) My experience with this board is that the max setting (1.55) provides the best results. I have not had a single crash or temperature variation as a result.

No not really, you do that with 45nm chips and your liable to kill them. Even with 65nm you dont need much over stock unless your doing extreme ocing. Play with the gtl ref first then the vtt.

Could you explain that one too.
