The VID is the Vcore required for your particular CPU to run stable and the stated speeds/specs. The VID range for your cpu is 0.85-1.3625. This means, that you can have any vcore as low as 0.85 and as high as 1.3625 for that particular model cpu to run at the stated speeds/specs by Intel. The lower the VID, usually means the better the overclocking potential a CPU has because technically, you have more room to raise your Vcore when overclocking before you hit the upper voltage limit. Just because your CPU states a 1.3v VID, you may still be able to lower it below that and be stable. It is just a "failsafe" setting to make sure the CPU will run at the stated speeds/specs.
