QPI / Vtt voltage ..what does it do ?

Hi all

what does "QPI / Vtt voltage" do ...can it be tweaked to improved performance ?
mine is set at 1.175 (auto) ...someone said he tweaked his to increase bootup time ...could this be right ?

Any help most appreciated

actually just tried it at 1.315 volts ...run prime and crashed (bsod) withing 3 seconds of running it .
just set it back to auto and prime running fine now

some CPU like QPI-VVT voltage to be high some like it low... you have to fine tune as every chip is different if yours is running stable on auto leave it at that...

yes i know what you mean ...if it aint broke , then dont try and fix it .
All is well with it using prime ...so i won't mess ...only asked as someone said it increased their boot time when they increased the voltage ...
Ow well thanks everyone for the info
