Variability in core clock and voltage of MSI GTX 1080 gaming graphics card
Variability in core clock and voltage of MSI GTX 1080 gaming graphics card
Hey everyone,
I recently got an MSI GTX 1080 Gaming X and started fine-tuning the clocks right away to optimize performance. The readings I’m seeing are between 2114 MHZ and 2153 MHZ. I’ve run through several tests in Heaven and multiple BF1 sessions, all showing stable results.
The main issue is that the voltage keeps fluctuating, which causes my clocks to drop. My temperatures stay under 52°C during benchmarks or gameplay, so heat isn’t the main concern. I can hit around 2139 MHZ at 1.075v and 2153 MHz at 1.083v, but those voltages don’t last long—usually settling between 2114-2120 Mhz at 1.050v.
I understand these changes are small, but I’m struggling to keep the voltages steady during extended testing or gameplay. I’ve tried forcing constant voltage via MSI’s afterburner and adjusted power management settings without success. Any advice would be greatly appreciated.
P.S. Here are the system details for reference:
