Nvidia To Fix Increased Clock Speed And Power Consumption At High Refresh Rates

PC Perspective had originally exposed a bug in the way Nvidia GPUs were managing clocks at high refresh rates, and the company has confirmed the issue and suggested that a fix is on the way.

When running the monitor at 60Hz, 100Hz and even 120Hz, the GPU clock speed sits comfortably at 135MHz. When we increase from 120Hz to 144Hz though, the GPU clock spikes to 885MHz and stays there, even at the Windows desktop. According to GPU-Z the GPU is running at approximately 30% of the maximum TDP.
