Nvidia is working on solution to high idle power consumption at high refresh rate
The idle power consumption of Nvidia video cards in combination with G-sync monitor with a high refresh rate is much higher than conventional monitors. Nvidia has confirmed the problem and working on a solution.
Ryan Shrout of PC Perspective discovered the problem when testing the Asus PG279Q, a 27 “monitor with G-Sync and a refresh rate of 165Hz. He noted that the test system consumed much more energy in idle mode or when a monitor used with a refresh rate of 60 or 120Hz. Consumption rose to as high as 200 watts, while the system is nothing other than doing the display of the desktop. A glance at the clock speeds of the GPU, the GTX 980 Ti, the higher consumption explained. Normally, the video card overclocked to 135MHz GPU back, but at refresh rates of 120Hz and higher took Shrout speeds of up to 885MHz true.
The problem would occur only in monitors with G-Sync. If using a 144Hz monitor without G-Sync-week support the power consumption in idle mode is not off. Shrout sent his findings to Nvidia and received a response from the video card maker. Therein Nvidia admits that there is a bug is in the way that the GPU adjusts clock speeds with the use of a monitor with G-sync, and a high refresh rate. The company claims to work on a fix that will bring down the clock speed of the GPU, as with other monitors. The solution should appear in an upcoming driver.Viewing:-202
