Specific to the motherboards tested, the results are as follows:


Turbo Boost was not functioning at extreme stress, so the CPU only ran at 3.20 GHz, voltage only remained around 1.34V, and hence VRM temperature stayed at 54.3 °C.


This board, like the ECS one, stuck at 3.20 GHz, with MOSFET temperature of 65.2 °C.


ASRock X79 Extreme4

This board's VRM was found to be reliable, according to the reviewer, it reached and maintained 1.4V CPU VRM. The CPU ran at 3.50 GHz, but throttled down to 3.20 GHz under extreme stress. Its VRM temperature recorded 89.8 °C.
