R9 series GPU & Gigabyte Motherboard possible incompatibility

George Sotiriou · Jul 17, 2014

Hello guys , this is my first post in the community so forgive any possible mistakes!

I have bought this new GPU, it's a POWERCOLOR R9 270 2GB OC and although I connected it on my PCIe and put the power cable normally I have a "no signal" output on my monitor though no beeps come from MoBo and the GPU's fans are spinning normally.
I have seen the solutions proposed on threads here (check PSU performance, check with other HDMI cable , check with different PCIe slot attempts, re-seat the memory sticks etc. etc. etc.) and none of them worked.

My last suspicion (that goes close to certainty) is that they are not compatible with either MoBo (and/or) BIOS and that I made a lousy purchase.
My motherboard is a GIGABYTE GA-Z77X-D3H and yes according to this page:
http://uk.pcpartpicker.com/parts/motherboard/?compatible_with=powercolor-video-card-axr92702gbd5tdheoc
...my motherboard is compatible with this graphics card.

Also according to the official page of my motherboard:
http://www.gigabyte.com/products/product-page.aspx?pid=4144#ov
...it says that I have PCI Express gen.3 support. So I don't know what to think.

Can anyone help me? Is there a chance that I can make this GPU work on my system? Any suggestions would be welcome...

Kind Regards,
George

It is definitely not the motherboard's issue. It would be either a PSU or the graphics card issue. What is the make and model of your power supply?

Hi ksham!
First of all I edited my original post because it turns out they are compatible with *D3H* variant of my motherboard. I was just looking at the wrong powercolor (been looking at 270X while I have the simple 270 - it's corrected).

To answer your question my PSU is a Corsair GS800. Suffice to say it's more than enough for a simple system which includes a mere i7-4770 processor , 16GB of RAM , and 3 Drives (1 SSD, 2 HDD).

Thanks for your interest.

try not using an HDMI cable . Any other connector will do

George Sotiriou · Jul 18, 2014

Outlander_04 :

Hi Outlander_04. Unfortunately this will not do either. You see I have 2 monitors connected on that GPU. Once with HDMI (my 27 inch one) and one with DVI-D (a small 17 inch as secondary). Both of them indicate "no signal" with the new GPU.

Unless you are suggesting that I try just one monitor (let's say my main 27 inch one) with the DVI-D cable.
Is that right?

Outlander_04 · Jul 18, 2014

just one , connect with DVI

make sure the dvi is connected to the graphics card and not the motherboard

Outlander_04 :

Did it. Still no signal from this damn thing!

Is this a new build or are you upgrading the graphics card?

George Sotiriou · Jul 18, 2014

ksham :

I was upgrading from a previous Sapphire Radeon HD5670 512MB but all preparations regarding the drivers have been made.

EDIT:
Well guys thanks all for your help. Solution has been found. I'm just putting it out here in case someone else runs into same kind of trouble. I went into the motherboard's BIOS and in PCIe slots settings I turned from EFI to Legacy support. That was my only change and the GPU is now workin perfectly well.

My only remaining question is WHY!? I mean on the box it clearly states "UEFI ready" (or this has nothing to do with it?)...
In any case if someone feels like replying to my last question just for the sake of it feel free to do so.
My issue has been resolved. Thanks all for your willingness!

Cheers!

Hello, just wanted to say I am experiencing the same issue, though with a different motherboard brand. But it is also a Z77 board.
http://www.tomshardware.com/answers/id-2224011/xfx-280x-3gb-strange-signal-detection-issue.html#13748239

My motherboard is a Asus P8Z77-V Deluxe, and the GPU that's giving me the no-signal/no-detection issue is a XFX R9 280X. I have the latest BIOS installed so I am not sure what the problem is. Tried everything; even bought a very fancy PSU for this (EVGA SUperNova G2 750), still no luck.

The strange thing about my case is that I can get the card to work in a multi-GPU configuration (see my thread for details), but not in single-GPU configuration.

I have tried changing all the boot settings in my BIOS to Legacy-only, but that didn't do anything for me.

Outlander_04 · Jul 18, 2014

How do you get to your BIOS if the screen shows "no signal" ?

ksham · Jul 18, 2014

Outlander_04 :

By removing the graphics card?

I don't know the reason behind the Legacy Boot though.

For the sake of the people finding this on google, flashin my bios to the latest version solved it for ME ( correct motherboard model and revision are needed). Sorry for the necro post but this is the top result on google and the answer was inconclusive, just want to share my experience

Hello friends, I am having the same problem , my mother board is a Gigabyte G1 Sniper h6 H97 , and my GPU is a MSi R9 280X , I can not video signal with the GPU , only through the OnBoard video card . I think it's BIOS setup, someone help me ?
Note: updated BIOS and drivers also updated

I just want to comment I had exactly the same problem.

I'm running a GIGABYTE GA-Z77-D3H, and my AMD R9 390 card refused to work - just no screen. I'd hear an HDD spin and then nothing. I'd even changed from my OCZ 650 w PSU over to a EVGA 750w psu, plus I'd RMA the first card I'd had back to the supplier.. I then read this thread, plugged DVI cable into the onboard graphics port, booted to the BIOS, changed over the setting as per the advice above, saved the change, rebooted the system, shut it down, and then changed over to my AMD R9, plugged in my Display Port adapter and I'm now gaming in 4K heaven - THANK YOU LOADS FOR THE ADVICE!

+1 This worked also for me with an 3770K, Gigabyte G1 Sniper 3 and an MSI 380X.
