from Witold Baryluk
I also tried echo profile_peak > power_dpm_force_performance_level , and initially the sclk stays at the highest level, but after a minute, it does drop just like other profiles. As of of cooling and PSU. I am sure I have plenty of headroom. The hwmon reports ~207W power at highest clock state, but temperature as reported by hwmon stays at 39 deg C. At lower clock states it drops to 37 deg C, and to about 35 deg C at idle. Looks to be just fine to me. My PC case do have extra ventilation, and CPU is pretty much idle. My PSU is Seasonic Prime Titanium (1000W). I have: Motherboard: MSI MEG Creation X399 GPU: AMD Threadripper 2950X at stock, liquid cooled, idle (~5% load), about 46 deg C. RAM: 8x16GB Samsung DDR4 ECC GPU: AMD Radeon Fury X, water cooled NIC: Melanox ConnectX-3 Storage: 2x Samsung PM983 via U.2 Cooling: Plenty of fans in Fractal Define R6 USB-C case. I just opened the case, and verified that two 8-pin PCI-E connectors are connected to GPU and PSU. I also verified that extra (optional, even on multi GPU systems) power connectors to MB are also connected to MB and PSU. GPU radiator is above the GPU, and is not hot to the touch or anything. Fan on it is spinning at max.
