When updating to BIOS 4402, I encountered several issues with system stability - so I wanted to share with everyone the settings I landed on that brought stability back to my system -- without compromising on performance.
The issues I was having included black screen requiring hard reboot after being away from the machine and screen freezing with no cursor or keyboard response. To further complicate things - there was no event logging to support troubleshooting or tracking down any hardware related issues.
System Hardware:
- ROG Crosshair VIII Hero (Wi-FI) - running BIOS 4402
- AMD Ryzen 9 5950X
- CORSAIR H150I Pro AIO
- CORSAIR Vengeance RGB RT 128GB (4 x 32GB) (PC4 28800) Model CMN128GX4M4Z3600C18
- ROG Strix RTX 3090
- Samsung 980 Pro with Heatsink 2TB (boot drive - other drives not listed)
- CORSAIR AX1600I Power Supply
Steps to mimic my settings:
- Enter the BIOS > Exit Menu > Load Optimized Defaults
- Extreme Tweaker Menu
- > Overclock Tuner > D.O.C.P. > D.O.C.P. Standard (This is to get the benefit of the faster memory timings)
- > CPU SOC Voltage > Manual
- >> VDDSOC Voltage Override > 1.15000 (This is because I was noticing voltage dips below recommend)
- > DRAM Voltage > 1.36000 (This is because I was noticing voltage dips below the 1.35 DOCP setting - refer to your memory!)
- Advanced Menu > AMD CBS > CPU Common Options > Global C-State Control > Disabled
Other unrelated BIOS settings I have modified from default:
For Graphic Card Support:
- Resizable BAR enabled (using the control on the top righthand side of the bios setting menu)
- - You can verify this setting is enabled within the NVidia control panel.
For Windows 11 Security Support:
- Advanced Menu > CPU Configuration > SVM Mode > Enabled
- Advanced Menu > AMD fTPM > Enable Descrete or Firmware TPM -- Your choice which to use
- Boot > Secure Boot > OS Type > Windows UEFI Mode
- After boot, check the Windows Security Panel - some items may need to be toggled on and require a reboot.
- These should enable Core Isolation, Security Processor, Secure Boot, and Data Encryption for Enhanced Security.
Within windows I also run the High Performance Power Setting: Control Panel > Hardware and Sound > Power Options
Once you reach a stable setting, dont forget you can save those BIOS settings using the instructions found here: https://www.asus.com/support/FAQ/1046388/
I hope this helps others move back towards a stable system and gain the benefits of the latest BIOS update.
