Dynamic Overclock Switcher 기능을 사용한 오버클럭 영상입니다
Curve Optimizer lets you tune the VF-curve
With the latest AGESA for this platform there's a new option hiding in the AMD Overclocking menu. It's called the "Curve Optimizer" and lets you modify the factory programmed Voltage-Frequency Curve when using PBO. Theoretically this should finally allow overclocking the 1T boost (without using reference clock) by combining it with an Fmax offset ("Max CPU Boost Clock Override").
There's no documentation or explanation available for what it does exactly. My theory is that it lets you add a voltage offset to the curve which affects what voltage the CPU thinks is required for each frequency. This leads to higher frequencies due to larger margin to the voltage ceiling and increased power budget.
ASUS DOS Overclocking
A new exclusive feature on the ASUS ROG Crosshair VIII Dark is the Dynamic Overclock Switcher (DOS). It allows you to set a load current threshold for switching between PBO and manual overclocking settings, including per-CCX overclocking. In theory this offers the best of two worlds, allowing you to maintain high frequencies when few cores are loaded and a manually tuned overclock at all core loads. Unfortunately I didn't have time to try this function myself, but check out these videos by SkatterBencher and der8auer which tests the feature:
Method
Any benchmark results are the average of three runs. HWInfo was used to record the monitoring information during the run. The average frequency was measured using the “Effective Clock” item. The average power was measured directly from the VRM controller and reports the CPU Core power only (excl SOC and other rails). Load-Line Calibration was set to Level 3 for the overclocked results. For the single-threaded tests, the affinity of the benchmark was lock to the highest ranked core according to CPPC.
At default settings we're already exceeding the advertised 4.9 GHz boost clock at 4945 MHz. Keep in mind that this is a sustained average during the Cinebench R15 1T benchmark. If the max recorded boost clock was recorded it would show several bursts above 5000 MHz.
After setting the Curve Optimizer to -15, the average sustained boost clock sees an increase to 5035 MHz while the boost voltage is reduced by 27 mV. By then setting the Fmax offset to 50 MHz the boost clock is further increased to 5065 Mhzat the expense of a 38 mV voltage increase. With Curve Optimizer set to -25 it was necessary to add a voltage offset of +50 mV in order to keep the system stable. These settings gave us an average boost clock of 5080 MHz and the voltage was now reaching 1519 mV. Further testing showed the limit was reached and there were no further increases. The frequency even dropped if the voltage offset was too high.
