ASUS Strix X670E-F, BIOS flash ended in disaster

[GrimReaper85]

Hi,

Today I wanted to update BIOS to latest 1709 as I had trouble with stability at DDR5-6000 and was only stable on 5600.

I went into BIOS, loaded system defaults and started EZFlash from BIOS. After about 5s I already knew something really bad happened as PC just restarted itself.

Then it was on a black screen loop, fans spinning and turning down, and I left it like that for 6-10 min at a time. There is also constant orange DRAM LED lit up.

My RAM is G.Skill F5-6000J3038F16GX2-TZ5NR. And CPU 7600X.

I then tried only left stick in 2nd slot and then right stick in 2nd slot. Same DRAM LED. RAM worked fine before so I would rule that out, both 2 sticks can't just go bad during BIOS flash.

Then I tried to flash it at the back BIOS USB port with BIOS Flashback, at least 5 times with 1303 which I had before and 1709 BIOS.

So I guess the motherboard is bricked. My biggest question is, how could this happen? BIOS flashing sure is not the safest thing to do with PC, but sometimes it is necessary and there should be a way back which in theory is BIOS Flashback, but in reality it doesn't help at all.

Hello GrimReaper85

Follow this video to rename the bios file and put it on your usb flash drive.

Once you have the bios file renamed and on your usb flash drive....

Insert the usb flash drive into the Bios port, press and hold the Bios flashback button until it starts blinking, when the blinking stops, the bios update has completed.

Start up your pc.

How does it go?

[GrimReaper85]

This is exactly how I was doing it, I read the manual.

BIOS FLBK LED flashes for 3 minutes and 30 seconds, then it stops. I believe everything is normal up to this point.

I just don't get why it doesn't boot anymore.

[Nate152]

Ok, it sounds like the bios update was successful.

If it's not booting for you, shut down your pc, press and hold the clear cmos button for 3 seconds.

Try booting up.

[GrimReaper85]

Same thing, no boot.

[Nate152]

Ok,

Is your memory installed in the recommended slots A2-B2? (2nd and 4th slots from the cpu)

You could try flashing the bios again with bios flashback, make sure your pc is shut down with psu switch on.

[GrimReaper85]

Yes, 2nd and 4th slot, same as before. Everything is the same now as the last year when it worked, I bought it on release date.

I tried flashing again several times.

I believe this mobo is good for RMA. I will start with it because there is almost zero chance CPU or RAM died during BIOS flashback, that would be very strange.

I'm not sure what could be happening but in this case, you may want to try flashing the bios back to a previous version.

I tried 1415 now. Then I removed the battery and cleared CMOS again.

Same DRAM led, only difference now is constant fan speed, not revving up and down like before.
