SLI issues

Hello, I am new to this so please excuse any mistakes that i make, I followed everything at https://wiki.archlinux.org/index.php/NV … abling_SLI and it works, but when I reboot I have a max refresh rate of 30Hz however, when I am on normal mode I get the 60Hz that my 4k monitor supports

fist step was:

 $ lspci | grep VGA
 01:00.0 VGA compatible controller: NVIDIA Corporation GP104 [GeForce GTX 1070] (rev a1)
 02:00.0 VGA compatible controller: NVIDIA Corporation GP104 [GeForce GTX 1070] (rev a1)
 

next:

 $ nvidia-xconfig --busid=PCI:1:0:0 --sli=Auto

 Using X configuration file: "/etc/X11/xorg.conf".
 Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
 New X configuration file written to '/etc/X11/xorg.conf'
 

then i get this

$ nvidia-settings -q all | grep SLIMode
  Attribute 'SLIMode' (ragelinux:0.0): AUTO 
    'SLIMode' is a string attribute.
    'SLIMode' is a read-only attribute.
    'SLIMode' can use the following target types: X Screen, GPU.
  Attribute 'SLIMode' (ragelinux:0[gpu:0]): AUTO 
    'SLIMode' is a string attribute.
    'SLIMode' is a read-only attribute.
    'SLIMode' can use the following target types: X Screen, GPU.
  Attribute 'SLIMode' (ragelinux:0[gpu:1]): AUTO 
    'SLIMode' is a string attribute.
    'SLIMode' is a read-only attribute.
    'SLIMode' can use the following target types: X Screen, GPU.

and this

$ nvidia-settings -q all | grep -i pcibus
  Attribute 'PCIBus' (ragelinux:0[gpu:0]): 1.
    'PCIBus' is an integer attribute.
    'PCIBus' is a read-only attribute.
    'PCIBus' can use the following target types: GPU, SDI Input Device.
  Attribute 'PCIBus' (ragelinux:0[gpu:1]): 2.
    'PCIBus' is an integer attribute.
    'PCIBus' is a read-only attribute.
    'PCIBus' can use the following target types: GPU, SDI Input Device.

and my conf file /etc/X11/xorg.conf
