Incorrect Core Voltage reporting on 9800x3D and Asrock B850 Pro RS

[rogmod]

Just testing before purchase but noticed that the processor core voltage was incorrect on Ryzen 7 9800X3D and Asrock B850 Pro RS Motherboard,

Version tested AIDA64 Extreme v7.99.7829 Beta.

AIDA64 reports 0.45V, CPUID reports 1.128V which is correct.

In AIDA64 please press Ctrl+D --> Sensor Debug --> ISA Sensor Dump. Copy-paste the full results into this topic, or attach the results as a TXT file to your post.

Thanks,

Thank you!  We've checked and the Vcore measurement should be accurate.  Please note however that when your CPU is running in low-power mode, it will lower its own core clock frequency and core voltage to save power.

Hi,

I have fixed the voltage in BIOS to 1.175 but AIDA64 still reports 0.388V

I have included a screen shot of CPU-Z and HWiNFO both showing Vcore as 1.176V.

I did notice in AIDA64 in the CPU info screen it says core voltage is 0.388 - 0.794V

Please copy-paste the full content of the Computer / Sensor page of AIDA64 into this topic.
