Although it was fixed with Geforce 361.43 drivers, it appears that Nvidia high refresh rate power bug is back again with the latest Geforce 364.47 drivers and causes the graphics card to clock higher in idle when paired up with a monitor setup which has a refresh rate over 60Hz.

The power bug, which raises the idle clock of certain Nvidia Geforce graphics cards in idle when paired up with a multi-monitor setup is back. The bug shows up when one of the monitors has a refresh rate which is higher than 60Hz and can have an impact on the power consumption.

According to a report from Techreport.com, the issue is apparently limited to certain setups and certain monitors. One of the TR readers noticed the issue with tripe ASUS PG278Q setup and Techreport.com managed to confirm the problem on the ASUS PG279Q running at 165Hz and paired up with LG's 27MU67-B running at 60Hz. In this configuration, the used GTX 980 Ti raises its default idle clock from 135MHz to 925MHz, thus raising the power consumption.

Unfortunately, the same problem was not noticed on a setup that was running on DisplayPort-connected Acer's XF270HU running at 144Hz and DVI-connected 60Hz smaller screen as it appears that the issue shows up when you are running on two (or more) monitors connected via Displayport.

While this is not a big issue it does raises a default idle clock and so it raises the power consumption by quite a big amount. Hopefully, Nvidia will soon fix this problem and issue a beta driver that will also fix the installation issues seen with its latest Geforce 364.47 WHQL drivers.
