SM Bus Controller?

[orangecat]

So I own a Gigabyte GA-Z68X-UD3H-B3 rev1.3 and after installing all my drivers I have a unknown device and a SM Bus Controller left under device manager in Windows 7 64-Bit I have read online that it helps system performance a fair amount to have this installed and I know its a chipset driver but Gigabyte dos not have this on their website and Intel was no use. So I guess what I'm asking is can someone point me in the right direction to find the download for this driver. I had it in the past but lost it somehow and I can't figure out how to get it back.

Thanks in advance.

Hey man I do this stuff all day at a local TigerDirect. SM Bus is usually the chipset driver. If not stuff like the lintel management interface, rapid start technology, sata drivers and sometimes stuff like card readers.
