Intel DZ77BH-55K and Asus Xonar Essence STX not working

[TJans3]

Hi Intel-Community,

I have a problem with the Intel DZ77BH-55K MoBo. I have flashed the latest Bios 0100 but that didnt solve my problem. I have a Geforce GTX 670 running along with a D-Link DWA-556.

Everything was runnning fine with the GTX and the D-Link plugged in. But when I tried to install the Xonar Essence STX things went bad. My System did not boot up anymore to Windows 8.1.

If Windows managed to boot up, the D-Link card stopped working and the Xonar Essence was detected. When I switched PCIe-Slots it was the same thing, but this time the DWA working fine. (Despite that, just the PCIe-Slot closest to the CPU was able to run the Xonar Essence. In the other PCIe-Slots Windows did not detect it.)

So in conclusion I can not get two PCIe-Cards running at once!!!

I tested the same setup (GTX 670, D-Link DWA and Xonar Essence STX) with another Mainboard (AsRock Z68 Pro3 Gen3 - Latest BIOS) and EVERYTHING worked!!

It has to be the Intel MoBo that causes the problem.

Anyone Can help?

Hello Noisr, let's first install the wireless adapter and sound card without the discrete graphics, using Intel® HD Graphics. Once you got them working try adding the graphics card.

I am sorry for the trouble, I believe this will work.

I tried installing everything as you described, but It didn´t work. I installed the wireless adapter with intel Hd Graphics, but when I tried to add the Xonar Essence it was not recognized in the device manager in windows. Also, the boot-process failed many times with both the DWA and Asus. Can I fix this problem with Software, because I don´t want to plug in and plug out my PCI-Cards like a hundred times?

I am not completely sure if this is a compatibility issue.

When that card is not recognized in Windows*, is it recognized in BIOS?

Can you share more information about your system configuration?

The http://www.intel.com/support/siu.htm Intel® System Identification Utility report would be helpful too.

Hi *,

I had exactly the same problem with my DZ77BH and my new Asus STX II. I saw the ID of the card in the peripherals overview of the BIOS but Windows did not seem to see it at all.

After reading a lot of useless tips and flashing different BIOS versions - without success that is - I tried to change every BIOS setting that I thought could have an effect.

And eventually I found the one setting that made the card appear in Windows. I disabled the "PCIs ASPM Support" and my problem was gone.
