Sorry, for the late reply, I have updated the UEFI with little effect, mine is running on a 280 rad, temperatures are completely stable at around 65 C under full load, it is just strange, in certain tasks, I only get 4.2 GHz, to be more specific, when trans coding video, I was able to get it up from 4.1 to 4.3 by increasing the multiplier to 4.6. Everything is completely stable at these speeds. When I play a game, it should be noted, I receive the full 4.6 GHz, however, I am still curious why I am not getting the full performance. There is no down clocking, I have checked with AIDA, there does not seem to be a problem, it appears to be a strange problem. I should note that I am trans coding with Plex, I am aware that it is not the best trans coder, however, I stream from it, so I wanted to optimize everything so that there would not need to be any on the fly trans coding when I request a video from a foreign location.
I hope this more detailed information helped.
Sincerely,
Jake
