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?
