Wrong chipset installed on ASUS P8Z77-V LX mobo?

Has anyone ever seen an instance of an other-than-advertised chipset being installed on a mobo? I have reason to believe my ASUS P8Z77-V LX mobo was fitted with an Intel H67 chipset instead of the Intel Z77 chipset I thought I was getting. Of course, there could be another explanation.

The setup first, then the scenario.

ASUS P8Z77-V LX mobo (BIOS ver 1306) (chipset driver version 9.3.0.1026)
Intel i7-3770K @ 3.5 GHz
16 GB (4GB x 4) G.SKILL RIPJAWS DDR3-1866
EVGA GeForce GTX 650 Ti 2GB
Win 7 Home Premium (x64)
500W PS

This system was purchased from iBuyPower in Dec 2012. I have a call in to their tech support, I am also awaiting a response from Intel tech support. I tried ASUS tech support, but their submission page returned an error message in a foreign language, so I don't think it went through. I'm hesitant to pop the heat sink off the chip to verify its identity in case I may need to RMA the whole thing. By the way, the labels/print on the board all indicate is is actually a P8Z77-V LX mobo.

The impetus for this whole affair is that I tried to use an external hard drive and noticed the USB 3.0 ports on the system did not recognize the drive at all. Neither the front panel (which is plugged into the proper mobo header) or the rear panel worked. The drive is a Western Digital 500GB residing in a Rosewill RX358 USB 3.0 enclosure. The external drive is recognized fine on my wife's Dell Inspiron 660 USB 3.0 ports. The ext HDD is recongized on my iBuyPower system in the USB 2.0 ports as well. USB and USB 3.0 are enabled in the BIOS.

Looking at the drivers in the Device Manager, I noticed the following.
1) In the IDE ATA Controller section there exists an Intel 6 Series/C200 Chipset Family entry.
2) In the System Devices section there exists two Intel 6 Series/C200 Chipset Family PCI Express Root Port entries and an Intel 6 Series/C200 Chipset Family SMBus Controller entry.
3) In the USB Controller section there exists an Intel 6 Series/C200 Chipset Family USB Enhanced controller entry.

It is my understanding the Intel Z77 chipset is in the Intel 7 Series/C216 Chipset Family. If I'm mistaken on this, then this is simply a "why doesn't my USB 3.0 work?" thread.

When I go to the Intel site and use their Chipset Identification Utility, it detects my chipset as the Intel H67 Chipset.

When I try to install the Intel 7 series drivers from the Intel site, or the corresponding MEI, the installer returns an error that my system does not meet the minimum requirements (probably because it detects an H67 instead of a Z77).

I'm open to the possibility that this is a driver issue, but I've tried uninstalling and reinstalling chipset drivers from the mobo CD, from the ASUS website, and from Intel. Still shows up as H67. I am hesitant to update the BIOS (current version is only from Oct 2012) due to the potential mismatch in chipset.

With my luck I probably got the one board on the production run fitted with the wrong chip, but it was "within tolerance", lol.

Any thoughts?

If you even think it's the wrong chipset drivers installed then the simple fix is to re-install the drivers:

ASUS P8Z77-V LX Downloads, select your OS and bit size (32 or 64-bit) - http://www.asus.com/Motherboards/Intel_Socket_1155/P8Z7...

Windows 8:
Intel Chipset Driver V9.3.0.1021
Intel Management Engine Interface V8.1.0.1263

Windows 7:
Intel Chipset Driver V9.3.0.1019
Management Engine Interface V8.1.0.1263

I recommend using the tested drivers from ASUS over that of the Intel drivers from their site. Afterwards stress test using an application e.g. AIDA64 Extreme Edition (all stress options selected) - http://www.aida64.com/downloads

Thank you, jaquith. I have tried to install the MEI for this board from the ASUS site, but the installer returns an error that the system does not meet the requirements (probably because it sees an H67 chip instead of Z77). The chipset drivers from the ASUS site (and my ASUS CD) install, but the Device Manager shows several entries of "Intel 6 Series/C200 chipset family" under system devices and the USB section instead of 7 series.

CPU-Z IDs the southbridge as an H67 http://imgur.com/AD6qd
SiSoftware Sandra shows several controllers are "Cougar Point" instead of "Panther Point".
I peeked behind the vid card to make sure they didn't give me an H67 board and it is the P8Z77-V LX board I expected (http://imgur.com/j3sAA) it is a Z77 board. I don't want to pop off the southbridge heatsink in case I need to RMA the system.

It seems the drivers may be less of an issue and the issue is the wrong chip was put on this board somehow someway?

Try booting into Safe Mode then re-install, and if that fails then the next step is to manually install the drivers (Browse my computer for software) under the 'System Devices' of the Device Manager. Lastly, if that fails and the drivers are all screwed-up then re-install the OS and Drivers from scratch -- that is after backing-up your data and if needed 'deauthorizing' purchased applications.

I am at a fresh install of Win 7 64-bit.

I booted into safe mode and installed the drivers from the ASUS site, but it automatically selected the 6 series drivers.

Again, in safe mode, I started the process to manually update the drivers. I pointed the Device Manager to the proper INF files for Panther Point (7 Series). When the "Show compatible hardware" box is checked, the only available option is "Intel 6 Series" (http://imgur.com/8jxXt). When the "Show compatible hardware" box is unchecked, other options are available, including "Intel 7 Series" (http://imgur.com/SUBmz).

I did not complete this process for fear of ending up in a BSOD situation, but if the 6 Series continues to show up as the only compatible devices isn't that telling of the chipset installed on the board?

There were several inconsistencies with this board. For example, looking in the BIOS http://i.imgur.com/0YLQS.png you'll see the Stepping setting is B1 (should be C1) and the ME is N/A (should be 8.X.X.XXX). Maybe a bad flash somewhere along the way? Wrong chip put on board? Anyway, not simply a driver issue, I suppose.

Ended up doing an RMA. Let's hope it comes back fixed!

Yeah, the RMA seems like a reasonable option and I hope that solves this oddness. :)
