The new graphics card's factory overclock appears to be inconsistent.
The new graphics card's factory overclock appears to be inconsistent.
I recently bought a used Inno3d GTX 980 Ti X4 Ultra from eBay. The card performed well and significantly improved upon my previous GTX 960 until I tried overclocking it. Using MSI Afterburner, I set the power limit to its maximum of 107% while keeping the offsets unchanged, allowing the card to operate at 1152 MHz for the core and 1800 MHz for memory. Both the Heaven and Valley benchmarks failed within seconds, causing my screen to display solid grey or black and requiring a hard reset of my PC. The only solution that worked was applying a -90 MHz offset to the core clock. Furmark, on the other hand, functioned properly even at factory overclock settings, so I chose to stick with the default speeds.
Recently, I experienced the same solid-colour-screen crash while watching a YouTube video, which prompted me to start this thread. Here are my details:
Motherboard: ASUS B150M Pro Gaming
CPU: i5-6500
RAM: 8 GB DDR3
GPU: Inno3d GTX 980 Ti X4 Ultra
PSU: Atrix 650T
OS: Windows 10
It appears my PSU, although likely suitable for the build, is a cheaper, lower-quality model. Do you think the issue is with the card itself, and should I keep it underclocked? Might the PSU be responsible?
EDIT: I also want to note that I left games running for extended periods with maximum graphics settings to test the card's stability, and it hasn't crashed yet. Additionally, the GPU temperatures have never exceeded 73°C, remaining around the low 60s during gameplay.
That GPU consumes around 300W of power. I’d want to verify this on another system just to confirm your setup. Also, it was overclocked by the manufacturer (boost exceeds 1240), so you might need to adjust voltage for stability. It’s close to three years old, which could mean some performance decline or degradation.
