Adaptive Voltage Measurements
Adaptive Voltage Measurements
There might be something I'm missing or the adaptive voltage setting on my board is faulty, which would be a problem since it would affect performance in the summer. With an adaptive Vcore of 1.185v on the 7820X running at 4.5ghz, the cores are still adjusting to higher voltages (1.23 - 1.31v) even when active, as shown by hwinfo. The power plan is set to balanced. Latest BIOS updates are available. Autonomous C-states are active. Voltage regulator operates in Balanced mode, not High Performance. Intel Speed Shift is on, Speed Step is off. It seems enabling both might be necessary. MCE is turned off. LLC is currently at Level 5 of 8; lowering it to 3 or 1 didn't resolve the issue. Disabling Turbo boost was tried out of curiosity but didn't help.
I haven't experienced anything great with adaptive vcore on my i5 8600k, it tends to be unstable even at 4.8ghz. I prefer a static vcore with LLC set to medium, high, or flat. To reach a 5.1ghz OC on my CPU, I'm keeping the voltage at 1.38 volts and a flat LLC setting. I might also try pushing 5.2ghz if the current OC remains stable in the coming weeks.

I've already discovered several stable CPU and cache OCs for this chip via manual Vcore adjustments, and even experimented with Adaptive two years ago without success. Now that I know Adaptive only reflects what the cores are requesting, not the regulator's actual output, I'm re-evaluating. I'm planning to compare thermal data under Prime 95 and OCCT using both adaptive and manual configurations to confirm this. Thanks for your help—I'm not alone in this struggle!
