Card was RMA's and replaced with a brand new R9 390x.  Installed and booted up without a hitch. All is well!

I'll take that trade any day =)

I tested and checked everything to get my Gigabyte GTX 970 G1 Gaming  working on the Z77 Pro4 but no chance. The card is only detected on PCIE3 but not in the proper PCIE2 X16 Slot.. 

I wrote an email to the support center from asrock but the answer was exact the same as here.

Is it possible that you guys can check this combination to?

My CPU: i5-2500k
PSU: Corsair CX750M
GPU: Gigabyte GTX 970 G1 Gaming (newest VBIOS)
MB: Asrock z77 Pro 4 (1.80)

Dear all, this is ASRock Technical Support Department.

We have read all the replys, and decide to do the test for this issue.
We tested using i5-2500(Sandy Bridge) and R9-270X(Gen3 card) with BIOS P1.80. 
The graphic card can run properly with above config, please refer the picture as below:

Noted that the card is running at x16 speed, which mean it is installed in PCIE2 slot. 
Therefore, it seems like not a compatible issue between this board and the graphics card.

For users who meet this issue, we provide some suggestions for try:
1. Since the PCIE resource is from CPU, please reinstall the CPU then check whether there?�s any bent or broken pins in CPU socket.
2. Unplug the power cable to do the clear CMOS settings.
3. If possible, please use another CPU or Gen3-graphics card to verify. 
4. If the problem still, please replace the motherboard or the graphics card to verify.  


Thank you for your patience.



Kindest Regards,

ASRock TSD

At this point I would say the 280x is probably a dud Cry

I hope you are able to return it.

So I was able to try it on an older system but it still did not work. Fans spun but no video. It also did not have onboard video so I couldnt check if it was being detected.

Again the PC was rather old and it probably needed a BIOS update but I did not want to compromise the stability of someone elses PC just to test this.

I'm sorry but that was the last suggestion I had. With no way to test if the 280x is actually functional we can't know for sure where the problem is coming from.

If no GPU was working in the system I would suggest reseating the CPU as the PCIE lanes are built into it but the 570 works so....

Tried cleaning the contacts and pre-installing the driver. still nothing.

As you know, then the PC is turned on, there is not signal. However, I know it is still loading to windows because i can hear it starting up through the speakers.

If you have already booted into windows and seen it is not detected then there is no need to use the share memory setting. That is not good news, it means the board did not pick up the card at all and booted from the iGPU even with the 280x installed. The iGPU should be disabled by default when a dedicated GPU is connected and the monitor cable attached to it. That means the card is not communicating with the motherboard at all.

Given that the card is second hand the last thing I can suggest is to carefully check the contacts on the card's PCIE connector for any damage or dirt and clean them off with some isopropyl alcohol and see if that helps.

Unfortunately I do not have another PC with an adequate PSU to test this on.

The card itself has no oily residue whatsoever and appears relatively dust free. The stickers (serial# and "void if removed") are intact. The card looks almost new. If im reading the serial# correctly, i think it was made on july 2014.

The GPU fans spin up when the PC is powered on.

With what I've tried so far, the 280x is not detected in BIOS or in the device manager.

I have not tried anything with the "share memory." I'll add that to the list of things to try in the morning.
