fixed: Incorrect Core Voltage reporting (ASRock B850 Pro RS + Ryzen 7 9800X3D)

[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

Thank you!  Please check the latest AIDA64 beta update available at:

After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

Let me know how it works.

Thanks Fiery, that's now working perfectly, much appreciated

Does AIDA64 have any promotions running or is it just best to subscribe to the newsletter and wait.
