Title: GTX 970 FurMark Crash
Post by: qc on December 22, 2016, 12:18:56 PM

I've encountered some isues with my setup lately and run the FurMark GPU Stress Test to test my graphics card. When running the FurMark in Fullscreen with 1920x1080 resolution the temperature of the GPU is about 70°C (where the cards max temperature is 98°C according to nvidia) and the water cooled cpu's about 50°C. Now here's the thing: When the furry donut is rendered, the stress test runs stable, but if i hit space to "toggle furry object rendering", the gpu makes some squealing noises, the temperature drops slightly and next the system shuts down completely. No blue screen, just a power outage. Even though the system logs are enabled, no log is written out. That doesn't make any sense to me, can somebody please tell me what is going on in the FurMark algorithm, when the fur rendering is toggled? As far as I understand the situation the fur rendering is quite an expensive technique, so by disabling it the card should have actually *less* to compute, why would it crash then, and not under maximum load? As the temperature should not be an issue, I first suspected my PSU but it is an Corsair VS650 (650W power supply), the gtx only requires 500W and the wattmeter I installed never shows a power usage > 350W for the whole system. I am absolutely clueless about what is going on here. If anyone has any idea what else I could try to diagnose the problem or has any insight about what FurMark is doing when the fur rendering is disabled, please let me know.

(Windows 10 64Bit, GTX 970 with newest whql driver, I7 4790K, MSI 7917-001R Mainboard GAMING 5, PSU Corsair VS650)

1. uninstall geforce driver to reboot pc
2. enter safe mode in boot and run DDU (display driver uninstaller)
3. normal mode and install new driver. ;)

A GeForce GTX 970 has a power consumption around 150W - 200W. The Corsair V650 should do the job correctly.

If you toggle the torus rendering, the GPU power and GPU usage should drop significantly like on the following screenshots:
- torus rendering ON: GPU power: 101%TDP and GPU usage: 99%
- torus rendering OFF: GPU power: 20%TDP and GPU usage: 34%

Test system: GTX 1070 + R376.09 + win10 64-bit

And yes, when the furry torus is not rendered, the GPU has less to do. Maybe a driver issue...

Thanks for the replies. I tried nuninho1980's approach, uninstalled the nvidia drivers, ran DDU in safe mode, installed the newest whql driver and started FurMark again. The furry rendering stable for 30 minutes (74°C in automatic fan mode, total system power usage 350W), then toggled the fur rendering. Interesting thing: coil whining again but ran stable for a few minutes. Turned on fur rendering and the system crashed instantly. When fur rendering was disabled, the power consumption decreased from 350W to 272W, maybe it is the promptly switchover, that would hint towards a psu fault, wouldn't it, now that driver issues are less likely.
Merry xmas, btw :)

Update: I also just checked the connections between the gpu and the mainboard/power adapters and even changed the pci slot. Only difference though, the system crashes again when disabling the furry rendering :/ I started gpu-z and moved it to the second monitor to check if there were any changes in the grapher, but since the system crashes the instant i hit the space bar there is nothing that would give me any new information

I'm having the same problem. Did you try a new PSU? Did that fix it?

I talked with the MSI technical support and he suggested that i replaced my graphicscard. It was still under warranty so i got a refund for the 970 and installed a new 1060 instead. FurMark runs stable for now, but the system keeps shutting down randomly in other 3D applications. Not the fault of the card it would seem so I'm going to replace the PSU next, it should arrive the next days... wish me luck

Replaced my Corsair VS650 with a be quiet! power zone 650 and the system runs stable since.

I am having the same problem. Did changing PSU solve the problem in long term?

I bought a new power supply and computer does not crash anymore when I am pressing spacebar while furmark is running, like it did crash every single time with old PSU. I need to do more testing, but looks that I had same problem as the original poster.

Yes. Still working with no problems. It was PSU.
