Can someone succinctly explain the load line calibration option in the Vision D BIOS, and what it does and what is the best setting?
I was playing around with it, and I set it from auto to a few settings and settled on medium (the ‘low’ setting resulted in application crashes under sustained load). Temps in Cinebench r20 have dropped a full 9 degrees at the same Vcore voltage. Just trying to understand. I’ve overclocked the 10700K to 5.1 GHz all core. In macOS, temps during a Cinebench run were kinda hot at 85-86 degrees. I’m using a Kkraken Z63 cooler, and macOS doesn’t have the benefit of adjusting the pump speed in response to temp. When I run Cinebench in Windows, same BIOS settings as above, temps were in the 70s. But in windows I have the benefit of NZXT ramping up the pump/fan speed responsive to system temp.
Now with the load line calibration BIOS tweak, the system consumes less power and generates less heat under sustained load. I’m now getting a respectable 77 degrees @5.1 GHz overclocked in macOS. which is awesome, considering a real iMac20,1 (that is not overclocked to 5.1 GHz all core) hits 99 degrees and throttles down during a Cinebench run. Thanks.
