I've bought it used few weeks ago and have been told that it was repasted recently, also 15W while staying at 60 celsius sounds real to me with its cooling system. I could be wrong tho.
I'm using ThrottleStop 8.74 with such settings
Even with installing driver, enabling powercut it still starts limiting power to 15W once ~65-70 celsius is reached. PL1 is red in CPU and\or GPU, sometimes PL1 for RING
What I'm doing wrong? Is there way to have 20-23W of sustained load, would...
