My CPU have FSB Wall and VTT is the only thing that helps for pushing it back. So i have this question - have VTT voltage peaks? I mean, currently in BIOS i have 1.44v, but in BIOS Hardware Monitoring VTT is 1.36v. For me, 1.36v is still safe, but is this value same all the time or while booting, restarting and under load it rise to 1.44v?

Here for 471 it need 1.42v VTT, but for 472 it needs 1.44v VTT. This is with 65x GTL vRef.
