Help with intel 4600

[DFerr8]

Hello guys, I have a small problem. I do not know if this is a problem, but my i7 4770k has an intel 4600. After using gpu z and other app's for gpu. They say my intel 4600 is 64bit (bus width). But I looked around and noticed that it is 128bits. What can this be? Here is a picture attached of my GPU Z. My motherboard is msi z87 gd65

Thanks for joining the graphics community.

I understand GPU-z shows 64 bit of bus width.

I have checked product specifications and this should be 128 bus width. This problem might be related to the graphics driver version you are currently running on your system.

Try updating to the latest video drivers version 3621.

Please filter by operating system and try to install the driver when it finishes downloading, to verify that your system will accept it.
