QFan Tunning completely corrupts BIOS

[Rogue194]

After using QFan (auto) Tuning, and saving, it would corrupt bios and be endlessly stuck in memory training cycle with frozen logo screens.

My setup:

B650E-F WIFI

G.SKILL X5 Flare 2x16gb

AMD 7700x

Phantom Spirit 120 SE

7800XT

RM850x SHIFT

Front 14mm fans are daisy chained and connected to its own slot, back fan is connected to another slot and CPU has its own connection slot.

EXPO I profile enabled in BIOS, along Windows UEFI and Sandard profile.

Did you install the (latest) beta 3040 BIOS? I am having some problems with it as well.

In any case, do a full bios reset first.

Hi @Rogue194 I think you might be conflating two things here. 

1. Initial memory training, and if Memory Context Restore is not enabled, the training process can take 2 to 3 minutes depending on the OC and memory configuration.
2. Can you reproduce the hanging behaviour if EXPO overclocking is not enabled? Do not enable EXPO and retest at Optimised Defaults.
3. Update to UEFI 3040 if not already done so.

I managed to hack it by disabling EXPO, setting all fans to PWM, checking "disable" on non-used fans and only then running QFan Tunning. Afterwards saved, and it properly rebooted after 2nd or 3rd freeze. I re-enabled EXPO profile in BIOS again and it managed to boot this time too.

Running QFan Tuning while EXPO is enabled and everything else set to auto seems to break bios upon saving. Still running BIOS v. 3035.

Sounds like the memory overclock isn't stable. 

You can check with Karhu Ramtest or HCI Memtest Pro.

Im using default "EXPO I" profile. Im not sure what else should I tweak?
