New Z690 Hero build, no display, Q-code 12

dingdongyo
Level 8
  • rog strix maximus z690 hero
  • 1 x 32gb OLOY ram, DDR5, 6000, PC5 48000 (not in compatibility list, but pretty sure it meets specs)
  • intel i9-14900k

can supply other info if relevant.

i just put all the components together and it will not boot, nor will it display anything. the only display output available is HDMI, i've used several different working cables and monitors. nothing ever displays.

The Q-code on the board gets stuck at 12. It displays other codes before that, but it doesn't get stuck on them so I'm assuming that's no big deal?

sidenote: i originally tested with more ram sticks in the slots and got stuck on Q-code 55 or 56. After removing all but one from the A2 slot, it gets stuck on 12. manual says that's "pre-memory CPU initialization is started".

I don't build often and I'm kind of freaked out that maybe one (or more) of these new components is bad, but i'm not sure what to do. I can't find specific instructions for flashing the BIOS on a z690 without a working display. and does that even make sense as a troubleshooting step? could the CPU be bad? i could really use some help. guidance much appreciated.

Could you have a look at the white sticker on the motherboard - the last 4 digits should be the BIOS version when manufactured. For 14th Gen, you'll need a minimum of BIOS 1720 I think, but later would be better. Anyway, if it has an earlier version, that's probably your issue.  

Use another PC to download the latest BIOS. Then unpack the archive and use the renaming tool in the folder. Best to use a tool like WinRar, because some people have reported issues when unpacking using Windows. Once done, place the renamed BIOS file in the root of your USB drive. Place that in the USB flash port and press the button for about 3 seconds. The light should start flashing. Now leave it alone until the flashing stops. It might take 5-10 minutes. Leave it longer if needed. Watch a guide on doing this before you do it if new to you. 

Once that's all done, try rebooting and see if anything has improved. Fingers crossed, you simply have an old BIOS. Updating to the latest version is a good place to start troubleshooting.

thank you so much for the detailed solution! I am away from home for the weekend but will try this ASAP and report back.

No worries, if using just one stick, it should be in the 2nd slot (A2). I think that's what you said you are trying anyway, but just to be sure.

The BIOS was the issue. I proceeded exactly as you described and it worked perfectly. The display finally worked, and there were lots of firmware updates/restarts before finally loading the new BIOS and eventually booting. Thanks again for your help, I'm so relieved that everything is functional!

Excellent, really pleased it was that simple 😁
