X570 Aorus Pro reverted back to F3 Bios

dr4g0nf1y · 7 Mar 2020 at 18:21

So I've been running on F11 for a while now and last night I shut down as usual and this evening it took a while to get into Windows. Once in I check to see if everything was set up to 3600MHz and it wasn't so I restarted and selected the profile I created. Again start up took a while and noticed the Aorus screen was like it was before.

Back in windows I check the clocks and restarted and it's back to F3.

Now I understand the Dual BIOS but does this mean the one that I installed F11 on is borked? I did nothing last night that should havet caused any issues.

Do I just flash the bios again or will this flash the second bios chip. Does this mean I have to RMA the board?

Thanks

There's a clear cmos jumper, that's about it. The manual has the location for B_BIOS and M_BIOS but I can't see anything specific to see which one is active.

The closest thing I have is the CPU/DRAM/VGA/BOOT (Status LEDs) but now that it has done whatever and I'm in the system they're not active.

Alright, will do.

After reading that thread it was slightly different. It was more to do with the bios not saving an xmp but was still worth reading.

furthest i got with mine was could make it boot
from the backup bios
but next boot it switched itself back to the older main bios again
bit peculiar i expected the backup bios to be the older one
but i got fed up with it and just left it in the end

This seems exactly like I have.

I can't tell what BIOS chip is running, unless it says somewhere inside it but I'm afraid to back in there.

The board was shipped with F3 but needed to flash it to F11 for the added memory support. I couldn't get the XMP stable so just used the Ryzen calculator and entered the timings manually in the advanced section.

Been perfect since then but now it's gone back to F3 I'm not sure if the Motherboard has switched chips or has re-flashed the original back to F3 or has fully died and I'm on the other.

The worst thing is I don't know why it did it.

In Windows it tells me f11 bios
But go into bios it tells me f3

What in Windows tells you that?

In Gigabyte SIV it tells me it's F3 and so does Bios but didn't see anything there teling me what chip. The first time I loaded it up after this issues it had to optimise all fans again.

Well it's good you managed to do it but I'm not aware of that method to flash it confidently
