在REDDIT论坛搜到了以下回复，说得比较详细，手动模式使用VRM电压部分去调整，OFFSET选择Global电压模式去调整电压：
Your CPU core voltage settings are exactly the same as on all other ASUS Z690 motherboards, they were simply added in a BIOS update. I'll try to explain what they are:
Actual VRM Core Voltage
This controls the actual voltage fed to the CPU. This is similar to VCore override from earlier motherboards.
Global Core SVID Voltage
This allows you to adjust the SVID request the CPU sends to the VRM depending on the core frequency. In the past this was called adaptive voltage mode
Cache SVID Voltage
This allows you to adjust the SVID request the CPU sends to the VRM depending on the cache/ring frequency. This setting is new, but allows you to control the SVID request from the ring.
SVID request:
The cores and ring/cache share the same voltage line. The end result being that whichever request is higher out of core and cache will win out.
If the cores request 1.35V, and the cache requests 1.30V, the VRM will get a request for 1.35V over SVID
If the cores request 1.20V, and the cache requests 1.30V, the VRM will get a request for 1.30V over SVID
It's worth noting that the SVID request sent to the VRM isn't the same as VCore. The VRM will apply less voltage at higher loads due to the electrical loadline. For auto load-line calibration on ASUS, mode 4, it's 1.0 mOhm (or 0.001 Ohm).
If the SVID request is 1.30V, the current draw is 150A, and the loadline is 1.0 mOhm, the VRM will deliver 1.300V - 150A * 0.0010 Ohm = 1.150V
VCore reported in HWiNFO or CPU-Z will not be correct for your motherboard, but ASUS motherboards should compensate the DC loadline setting properly so that VID is usually the same as actual VCore under load. |
