Solved SM Bus Controller Problem

Asus motherboard / P8 z77-v lx2
January 16, 2014 at 14:42:25
Specs: Win 7 home 64 bit, Intel i5 3570
Hi,

just finished my first self build and I'm updating drivers etc.

Device manager shows an exclamation on my SM Bus Controller.

I have googled this and posts seem to suggest that I should seek drivers from the Intel website, but I can't see what it is I need and seem to get stuck in a loop there.

My motherboard is an Asus P8 Z77-V LX2 and my processor is an Intel i5 3570.

Can someone help me figure out where I should go or what I should do?

Thanks.

I don't know if this is the chipset driver you used or not, but try this one:

http://wikidrivers.com/wiki/Intel_C...

In the Downloads section, there are two links, try downloading the first one and installing it. (It is the .exe download.)

Yes, go to asus and download the chipset driver and install it, make sure you use the correct version for the operating system for 64 bit. The smbus controller is usually part of the chipset installation, but it can also be part of the VGA driver particularly with Nvdia. I would install the chipset and see if that solves the problem.

I have already been there and downloaded and installed the latest chipset drivers. But still have the complained of error.

Any idea what to do next?

Did you see the part where sometimes it is included as part of the Vga driver? That is the most likely other cause though again it is usually with Nvidia. Then there is the odd ball (maybe yours) where it lists "sm bus controller" and it can literally be any one of the drivers listed. I suggest you use the drivers provided by Asus and not intel in this case, but they do list all the drivers and one of them should make that disappear.

Maybe someone else will help;)

I'm really not sure...

I did use the Asus drivers and not Intel because I couldn't find the intl ones.

As you mention VGA etc., is it likely installation of a new graphics card may solve my problem? I have a new one due in the post next week.

I'll update after installation.

Well I installed my new graphics card and its working correctly, but this SM Bus Controller problem persists.

Does anyone have any advice?

I'm totally stumped.

In the device manager, right-hand click on the device in question and click on 'Properties.' On the properties window, click on the 'Details' tab and change the 'Property' drop-down to 'Hardware Ids.'

Please post back the the line that looks like this:
PCI\VEN_1002&DEV_68F9

Note that I'm only looking for the 'VEN' and 'DEV' Id's.

Using this information, you can do a Google search and either find the driver you need or at least find out who the manufacturer of the SM Bus Controller is so you can maybe download the driver from the OEM's website.

These values are as follows:

PCI\VEN_8086&DEV_1E22&SUBSYS_84CA1043&REV_04
PCI\VEN_8086&DEV_1E22&SUBSYS_84CA1043

Fantastic, it worked!

Now I have a ton of things listed under system devices, but no little yellow exclamation marks.

I still have no idea what it actually did, but I'm a happy camper now.

Thanks for the solution.
