Rog Strix X670E-E not saving changed settings in BIOS

[LeoRubira]

I've tried everything, assembled and disassembled the PC about 5 times. I updated the BIOS several times, replaced the motherboard battery with a new one. I reinstalled the entire operating system 5 times. I prayed a whole rosary to the computer saint and nothing worked. So I decided to return the motherboard to the store because I was sure it was a problem with a faulty component. Another new board arrived and then I did all the same procedures to finally start working with this computer and the same problems came up: changed BIOS settings in the system are not saved and go back to the original state on every reboot. The motherboard LEDs are lit with the computer turned off and the DDR5 memories come in at a speed of 3600MHz!

Hello,

Are you receiving any messages upon boot? What settings are you attempting to change that aren't saving?

I notice in your signature you've combined two memory kits, which is not recommended. It's possible the system is failing memory training and entering safe mode, so the memory parameters will return to stock. Try removing one of the kits and report back with your findings.

Hello Silent_Scone
I don't get any BIOS error messages.

At this first moment I'm trying to simply change the led light on the motherboard that stays on even after the computer is turned off.
The path for this procedure is as follows Advanced > Onboard devices configuration > Led lighting > When system is in sleep, hibernate or soft off states > Change from Aura Only to Stealth mode

I tested starting the system in safe mode to make the BIOS changes, save them and also analyze if the speed of the memories would be corrected. None of the options worked.

I removed the memory sticks which are two kits of 64 with the codes numbered xxxx16, xxxx17, xxxx18 and xxxx19. I installed the ones code xxxx16 and xxxx17 according to the memory configuration recommended by the motherboard so that they act in dual channel in the DIMM_A2 and DIMM_B2 slots. With 64GB the memories operated at 4800MHz, correcting the previous speed that operated at a frequency of 3600MHz. So I lost a lot of money in acquiring these extra memories that complete 128GB. I'm going to contact Kingston here in Brazil where I live to see if they offer any exchange possibilities. In Brazil there are no 128GB DDR5 memory kits for sale.

Even with the memories operating correctly with the 64GB kit, my BIOS does not save the previously modified changes.

Thanks for the help but I still need some support on how to fix this BIOS issue that won't save changes.

BIOS Version: 1416 x64 05/16/2023
EXPO > Disable
DRAM Status DIMM A2 and B2: Kingston 32768MB 4800MHz

Could you perhaps upload a video of what is happening now that you've removed the additional memory kit?

If you go to the top bar menu in the UEFI and click Aura > Stealth Mode. Upon reboot, do the LEDs remain off?

[LeoRubira]

Yes, upload a video more specifically than?

If I go to Advanced > Onboard devices configuration > Led lighting > When system is in sleep, hibernate or soft off states > change to Stealth mode and save by pressing F10 the computer restarts normally. When I turn off the computer, the Stealth mode function does not work and the motherboard LED remains lit. If after changing Stealth mode / starting Win 11 / restarting the machine / entering the BIOS again, the Stealth mode option returned to the original BIOS default in Aura Only mode. Any change I make, when I restart the machine after booting it goes back to the BIOS default values.

For future reference this setting can be changed from the top bar under Aura, no need to browse to onboard devices. These functions do the same thing.

Go to Advanced\APM Configuration > change to S4+S5. See if this helps.

SOLVED by Silent_Scone! 
Thank you very much my friend 🖖

For those who suffer the same problem, follow the steps to fix the BIOS that does not save changes and that the motherboard LEDs remain lit:
Access the BIOS through the DEL or F12 button on computer boot.
In Advanced > APM Configuration > ErP Ready > change to the option Enable (S4+S5). In the following text I explain what this function does.
To turn off the motherboard LEDs, now access:
Advanced > Onboard devices configuration > Led lighting > When system is in sleep, hibernate or soft off states > Change from Aura Only to Stealth mode.
Save the settings and restart the system, the information will be saved inside the BIOS.

"System power state S4, the hibernate state, is the lowest-powered sleeping state and has the longest wake-up latency. To reduce power consumption to a minimum, the hardware powers off all devices. Operating system context, however, is maintained in a hibernate file (an image of memory) that the system writes to disk before entering the S4 state. Upon restart, the loader reads this file and jumps to the system's previous, prehibernation location.

Software resumption
System restarts from the saved hibernate file. If the hibernate file cannot be loaded, rebooting is required. Reconfiguring the hardware while the system is in the S4 state might result in changes that prevent the hibernate file from loading correctly."
