Hi All,

Im getting a new Z690 Hero board and a new 13700K processor. I'm upgrading from a Aorus Z390.

I saw that in order to use the latest 13th gen processors you need to update the latest bios using Bios Flashback. I read the manual and it seems straight forward. But at the same time my friend got a Z690 Extreme board and bios flash back did not work for him.

Im just wondering if there are any users who updated the bios using bios flashback ? (Only connecting the motherboard 24 pin connector and cpu 8 pin connector)

if there are, please share your experience :) would be helping me out a lot.

Thanks!

Hi all,

I'm at wits end here since all I did was update the BIOS when giving my machine a fresh Windows install.

I went to update to Build 4505 (Up from one of the earlier 4xxx or later 3xxx) and my system won't POST out of "SAFE Mode."

I did not do any hardware upgrades. I did not do any hardware changes. I never overclock and prior to attempting to update BIOS and reinstall Windows, my machine was flawless for the past 2 years.

Any ideas please?

Mobo: ASUS ROG Maximus Z690 HERO

RAM: 2x Dual-Channel 16GB (total 4x sticks for 64GB RAM over two RAM sets)

CPU: Intel 12900K Alder Lake

I built this system back in 2022 and it's been great, up until now.

Help! I work from home and depend on this machine for work :(

Hi guys, I’m building my first gaming PC and I just bought the Asus ROG Maximus Z690 Hero motherboard and the Intel Core i7-13700K processor (waiting delivery).

I saw on Asus product page that Z690 supports Intel 13th Gen but then I saw a lot of threads regarding BIOS update…

Do you guys know if Asus is already sending this motherboards with a new/recent BIOS version to support 13th Gen?

Thank you.

Hi all,

Sorry for the long post.

I’ve had a really weird issue the past two times when updating my Asus Z690 Hero BIOS. Every time I update the BIOS I do prior checks such as running benchmarks and observing voltages, temps, etc and everything is rock solid. I installed a contact frame for my 12900k recently and confirmed there are no bent pins. I forget the BIOS version prior to 3101, but I just updated to 3701 today.

The problems start post BIOS update. These past two times I’ve tried using the flashback and Ez BIOS update tool within the BIOS and both have the same code 55 error upon restart.

My understanding is that code 55 means there is no ram installed. I have two Corsair Dominator 6200mhz sticks fully seated in A2/B2 slot that give error code 55 and will not POST. If I remove B2 then the system will POST like normal. When I move stick A2 to B2 slot the system will POST. However, the system will not post with stick B2 in slot A2 or B2 or when both sticks are in A2 and B2. I made sure to clear the CMOS between tests.

Normally this would lead me to believe that B2 stick is bad; but I refuse to believe a BIOS update destroyed a DIMM that was working perfectly fine minutes ago and especially considering this happened the last time I updated the BIOS.

I did some further testing and here is where things get extremely weird.

If I boot the computer to desktop with stick A2 using BIOS defaults and XMP disabled then add stick B2 back in while the system is running (essentially a hot swap) and restart, the system will POST on restart with no issues but windows or BIOS will not recognize stick B2.

If restart and go to the BIOS to enable XMP 1 with only stick A2 recognized in BIOS and do another reboot upon POST both A2 and B2 sticks show up with no memtest errors and the system is perfectly stable.

My question is why is this happening and is this an Asus or Corsair issue? I’ve already had to RMA one set of ram the first time my PC wouldn’t post after building it and this happening again.

Has anyone downloaded the latest BIOS update? I built my PC yesterday and currently can’t boot because of boot error Fb and Ad. Does anyone know if the newest BIOS update will fix this or if it’s a safe update? Should I even try to update the BIOS?
