Z790-e BIOS 1801 SVID Offset having no effect

I just updated to a Z790-E board and working on just undervolting stock speeds. For some reason SVID offset is having no effect on voltage once I drop it below around -0.1. around (1.3-1.314V idle). Same goes if I adjust the V/F curve. I can successfully lower the SVID below 1.3 if I bring down ACLL but I have no clue why SVID offset isn't working. Previous board was Z790-H and I did not have this issue. Curious if its the BIOS 1801 since my last board had the previous 1501.

Hi,
Check if changing SVID behaviour is having an impact. Set Best Case Scenario.

Tried that but then I can't really test the use case because that brings my voltage down enough that i don't need much offset. I usually set ACLL manually though. This board doesn't really like anything under .1 - .15 (don't know why I would think ACLL value doesn't really matter since it just shifts the V/F curve, but I find system is more stable between .1-.15 and then make small adjustments with the V/F offset.

At the end of the day the issue doesn't matter too much as I can use ACLL to bring  SVID voltage down most of the way and then make small adjustments with V/F Offest. Its just really weird that after -.1 or -.11 of Global SVID or V/F SVID offset it stops having any effect. Seems like maybe a bug with 0801 BIOS but I would assume someone else then would have seen this behavior.

SVID behaviour manipulates ACLL anyway. How are you applying the offset?

I have specific information on the Z790-E motherboard BIOS version 1801 or any related issues with the SVID Offset. However, I can provide you with some general information and troubleshooting steps.

  1. BIOS Updates: Ensure that you have the latest BIOS version installed on your motherboard. Manufacturers often release updates to address various  gb whatsapp download  issues, including those related to power management features. Check the official ASUS website for your motherboard model to download and install the latest BIOS.

  2. Default Settings: If you've made changes to the SVID Offset or any other settings, try restoring the BIOS to default settings and see if the issue persists. This can help rule out the possibility of conflicting settings.

  3. Contact Support: If the problem persists, consider reaching out to ASUS customer support. They might be aware of specific issues related to BIOS version 1801 on the Z790-E motherboard or offer guidance on how to address the problem.

  4. Community Forums: Visit online forums or communities where users discuss ASUS motherboards. Sometimes, other users may have encountered similar issues and may offer solutions or workarounds.

  5. Documentation: Refer to the motherboard's user manual or documentation for information on the specific settings in the BIOS, including the SVID Offset. The manual may provide insights or guidelines on how these settings are intended to function.
