Hello,

I have the HD 7790 and I absolutely love it. But for the past one week a strange issue seems to be cropping up. My GPU overheats and the system shuts down. First let me come to the diagnosis and how I got to it. 

1. I did stress tests on my CPU and logged the temperatures: 50 degrees each core.

2. I did stress tests using OCCT and I saw on full screen the temperature escalated to 74 degrees. I logged the results using GPU Z and I saw that the temperature was indeed increasing drastically.

3. Next, I opened up my case and did the same test again, the temperature readings were same. Conclusion: Case air flow isn't the problem.

4. Opened up catalyst control center and Checked manual fan control in AMD overdrive. Switched fan speed to 90 percent. Did same test again. The temperature was now barely at 55 degrees. The test passed.

So, to summarize. My GPU fan speed doesn't increase in relation to the heating of the GPU. I have tested the PSU already, but #4 should be proof that there isn't anything wrong with the PSU. How can I get the GPU to automatically increase fan speed and why did this issue even crop up after 10 months of usage. I have played all heavy gfx/rendering games before (Metro LL and Cry3) but now this issue seems to have cropped up randomly.

Do I need to re install the driver? Do something with the firmware? Please help.

Specs: Intel G2130 3.2GHz, HD 7790, GA - Z77 - DS3H, Corsair 500MX, 8GB RAM. 

Tools Used: OCCT, CoreTemp, GPU Z.

Catalyst Build Version: 2013.0314.338.4633

74C shouldn't be nearly enough to crash a system, but what you can do is get MSI Afterburner, it allows you to set a custom fan curve so that the fan spins faster as temps get higher.

Yet it is. I made sure of that by keeping the fans running on 90 percent so that the temperature remained low. So, it is the GPU overheating that shuts down the system.

Thanks for the tip btw. I will download it and report back with the result.

 

Cheers

74c is no where near enough to cause any issues. Max tempature depends on your model (G73jh was set to shut down at 114c as mentioned by asus techs).

 

I would check your event log and look for errors and try to fix them through google or just do a clean install of your operating system.

Okay now it seems to be shutting down at even lesser temperature. I installed MSI afterburner and set a really steep curve. It worked for a while, now it shuts down while playing FTL! It's probably the most lightweight game I have ever seen! 

Okay, so here's something that I forgot to mention earlier. My MB's BIOS got bricked a few weeks ago, at that time I had already installed the OS. So when the MB came back I didn't do fresh install. Do you think that could have anything to do with this issue?

Okay I did a new install of my OS but the problem still persists. Afterburner doesn't help either. What do I do?

Hmm.... since u did a fresh install, it sounds like there is an issue with afterburner itself.

Does it shut down if you don't have afterburner? IF it doesn't, and If your goal is to overclock, you can try an alternative like a gpu overclock tool from amd (google it)

 

You can also check for any Bios and Vbios updates (if any) for your model.
