Hi there,

I recently bought an ASRock z87 Extreme 4 Motherboard. This motherboard is an upgrade to my previous one, where everything was working fine. I have an AMD 7850 as my GPU for this computer. After upgrading the Mobo and CPU (i5 4670k), everytime I install my GPU (all seated properly, power cables proper), I get the Dr. Debug code d6, followed by the 5 beeps from my mobo, indicating a lack of graphical output. When I used this exact GPU on my other desktop (an Asus z68 mobo), everything works fine.

Even weirder is when I use the Nvidia GTX 560 from my other desktop and put it in this one, it WORKS! I am extremely dumbfounded by this. I really prefer my AMD 7850 to the 560 so I need the GPU in my computer, so can anyone find the issue?

Here are my specs

i5 4670k
ASRock Z87 Extreme 4
AMD HD 7850 (MSI Twin Frozr)
Seasonic M12II 620w
4GB RAM (on one module atm)
500GB HDD
2TB HDD

I have updated my motherboard BIOS to the latest one, but my drivers are all from the CD provided with the Mobo (except for INF, I updated that one too). I really would appreciate just any form of help guys.

THANKS

I would contact ASRock support.

In the meantime, it might sound strange, but downgrading to an older BIOS version might help. Also, I don't know if you checked your BIOS settings for anyting related to GPU, maybe there's something in there that the 7850 doesn't like. You could also try to reset BIOS settings to default.

Ok I'll contact ASRock (I've heard nightmares of their customer support tho)

This problem was also there when I first installed the mobo, so I already tried it in an earlier version.

I haven't done anything in the BIOS yet, is there anything I can do?
