So, I just install fresh Fedora 24 with kernel-4.5.5, then remove nouveau from
system completely:

1. # echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf

2. Paste ‘rd.driver.blacklist=nouveau’ to end of ‘GRUB_CMDLINE_LINUX=”…”  in
/etc/sysconfig/grub

3. # grub2-mkconfig -o /boot/grub2/grub.cfg

4. # dnf remove xorg-x11-drv-nouveau

5. # dracut /boot/initramfs-$(uname -r).img $(uname -r)

After this steps reboot, upgrade system to kernel-4.6.5, and install nVidia
proprietary driver. Everything works just fine.
