Greetings. Not long time ago i bought new monitor Benq XL2430 with 144 Hz refreshrate, and found some issues with my gpu MSI R9 380 4G. When i choose 144 Hz in video card settings, memory refresh rate starts working on it's maximum. In idle my videocard should down to 300 MHz gpu and 150 Mhz memory, but if i have 144 Hz refresh rate it's working on 300/1425 and heats up to 60 C. Fans at this time periodically start working and stop after 10 sec. But if i choose 120 Hz refresh rate, it works as should on 300/150. I've tryed old Crimson and new Adrenalin drivers, and nothing helped. I even tryed all windows power modes, and has no result. Sorry for my bad english, but i hope you will help me with this issue. Thanks.
