declan Posted October 18, 2013 Share Posted October 18, 2013 I have a dell m6700 with IPS screen. While the screen is fantastic the combination of Nvidia and IPS screen does not support optimus.Is it possible to underclock the GPU below what is possible using the standard windows software power save profiles. If so how much power can you realistically save. I'm thinking of a situation where you are stuck on a plane for 8 hours and want to do something simple like typing letters where the graphic card is not really being used much and need to conserve battery.

inyue Posted October 18, 2013 Share Posted October 18, 2013 Underclocking my old Asus G73JH with 5870m to his minimum level (approximately 100/100 clock) gives me like no more than 15% of the total battery life.... Quote Link to comment Share on other sites More sharing options...
