OFFICIAL Bios ver. 2004 will not allow bios flashback THREAD

Hi all,

It looks like at least a couple of us have an issue flashing back to earlier bios with ver. 2004. Both with the UEFI method and the usb flash back will not work (3 usb drives and none worked). The bios setting to allow this is enabled. I have a Z690 Hero.

If you have this issue please reply to this thread so we can keep all the info in one thread. It will help if you list your MB model as well.

Thanks
( I should also note that the voltage issues found in ver 1720 appear to be fixed in 2004.)

UPDATE - It seems that real time ram timings can't be changed using Memtweakit or any other tool. Was working on 1601. Can anyone else confirm this?

Hi,
I have the same problem with Bios 2004 on ASUS ROG MAXIMUS Z690 EXTREME - No method will allow me to go back to any earlier Bios.

EZ Flash 3 give error "File is not a proper BIOS" with any Bios except 2004. Flashback just stops with any Bios except 2004.

I need to go back to Bios 1101, as this is the only Bios, on ASUS ROG MAXIMUS Z690 EXTREME, that lets a single GPU run at X16 in the top PCIE slot - Now will only run at X8.

Regards

Asus needs to aknowledge if this is a bug or a feature.

It has to be a bug cause it eleminates Bios flashback.

Iam rock stable at 1505 with 6600mhz DDR5 not updating.

The mods all saw this thread, and, as usual when answers are needed, radio silence.

Guys, just answer the question!! :mad: How infuriating.
I Think I'm so smart, that I'm dumb enough to believe it!!
