Hey.

Yesterday i bought a SAPPHIRE NITRO+ RX 480 4GB and everything was fine until it randomly started using 100% fans and shutting down. Even when i was starting windows the same happened, 100% fan usage but it stopped when i reached the desktop.

Case: Nox Hummer Zx Zero with 5 fans
Mobo: MSI H97M-E35
PSU: XFX Pro 550W Core Edition
SSD: Samsung 850 evo 120gb
HDD: A random green WD 1TB
RAM: Kingston HyperX Savage DDR3-1600MHz 8GB x2
CPU: I5 4590

I use MSI Afterburner and i had a custom fan curve when that happened, the second time happened with TRIXX when i made a custom curve as well(turning off afterburner's fan curve, ofc).

Now i'm using nothing and i'm waiting until it happens again,

Could it be the PSU or is it the drivers?

Thanks in advance.

Yes, this is from testing with Furmak:

EDIT: Ah, I took that one with the custom fans. With the Auto setting, the card was reaching 80°C and fans ~50%. When gaming, I never go beyond 65°C and fans ~40%.

Cheers!
It is normal behavior in the "Auto" settings for the card. It does turn off the fans and stays at 40°C when IDLE at the Desktop. If that bothers you, you can set a custom FAN profile using TRIXX, but make sure the starting point for the curve is not at 0% fan.

As long as the fans start spinning again under load, I don't see an issue with that behavior personally.

And I also have the Sapphire Nitro+ RX480 4GB.

EDIT: I installed Afterburner, but it didn't work well with the card, so I uninstalled it and I'm just using TRIXX.

Cheers!

Thanks for the answer.

What i meant was, the card itself shutdown when that happened. I was in the desktop, the fans started going to 100% and the card turned off. I had no image in my screen.

Maybe i should just keep one of them, Afterburner or Trixx.
 
Oh, then I totally missed that from what you said.

If that is the case, then maybe the PSU is not delivering enough power to it. That is the first thing that comes to mind.

The RX480 can sip a lot of power if you OC it, so I think you might want to try this: underclock it and test again; you can set the power limit to -20% and put the clocks as low as possible (GPU only, not VRAM). If it doesn't shut down, then it is the PSU. If it does, then it's the card that is faulty (most likely).

If it is the PSU, then it would be a weird one... From the spec sheet I can see it's a single rail PSU providing 45A. That is plenty for it to be under the water pushing that RX480.

Well, in any case, keep getting data so we can come up with more theories.

Cheers!

Thank you.

The strange thing is that it didn't happened under stress. GPU usage was at 0% or so when the fans started spinning.

Could it be the psu connection? I used a 6+2 pin to connect the gpu. Also i have another 6pin and one 8pin (which i don't know what is it for, since my psu should not have it and i'm afraid to use that 8pin when i don't know its use).

I kept the default fan curve and played for a while and everything is going well. I will keep this updated.

For now i suspect the problem was the custom fan curve.

Anyway, since you have the same gpu: with the stock fan curve, are u hitting 75º?

My case has 2 front fans sucking, 2 top pulling out and the back one the same. Not sure if the airflow is nice, but i'm getting 70/75º both gpu/cpu(stock cooler)

Just keeping this update in case anyone has the same problem.

So i tried a custom fan curve with Trixx, everything was going fine. When i installed AMD gaming evolved (Raptr), i got a blue screen saying "Thread Stuck in Device Driver". I searched a bit and some people say the problem is the in-game overlay.

I will use DDU to make a clean driver install; uninstall Amd Gaming Evolved (Raptr).

If the problem persists i will update the BIOS -> uninstall Trixx -> DDU -> Clean drivers install.
 
Ah, yes. That is an important piece of information from me as well.

I don't have the GE client. Only the drivers and the GUI for them.

Also, I moved from a Sapphire Vapor-X 7970Ghz to the RX480 without doing a full clean of drivers; just uninstall, swap cards and install new ones. Same Win7-64b and everything else.

Cheers!

Updated the bios, uninstalled every software monitoring software (Afterburner, Trixx, etc), clean drivers install with no AMD gaming evolved (raptr). Now everything seems fine, tested with 3dmark with no problems.

Also changed my bios to the 1266Mhz one instead of the 1305Mhz, only noticed 1 fps change but with the temperature decreasing 5º or 6º while in 100% usage.

My opinion: awesome card, never experienced this kind of performance (in a good way). Apart from these software problems, everything seems fine. Nothing unfixable. If you have this card: stay away from hardware monitoring software, at least until they fix the problem.


Also thank you, Yuka. For the opinions and the help.

just saying. Don't understand why you listed your Case, SSD HDD RAM
