Gigabyte UD5H Z77X shows LED code B2 & 4 beeps w/ new GPU

Vevec · Jan 5, 2016

Just bought a new 970 for my ~3 year old rig. When booting up for the first time after installing the new card (and every time since then), the motherboard beeps 4 times, with about a 30 second pause between each beep. On the 4th beep, it boots up seemingly just fine. I've had the card for about a week now and haven't noticed anything unusual about it or the computer at all, but I'm hesitant to let it go.
If there's that long of a pause between the beeps, is it a beep code or something else?
Also, the LED code on the board is showing "b2" during the beeping process, which according to the manual indicates Legacy Option ROM initialization. I've read about that and can't seem to find a definitive solution.
Update: Just checked all the USB devices (unplugged them all) and it booted up just the same. The BIOS splash screen won't respond to my keyboard input either, so I can't check any system info from that.
I could try and update the board's BIOS, but I'm not sure what revision of the UD5H I have.
edit: seems I have the F7 BIOS version from 5/11/2012(found using HWiNFO), and the revision is 1.0.
I assume that if the new card is working fine otherwise, it's not an issue with the PCI slot?
Any help would be greatly appreciated.
Edit 2: Well, my computer's been running fine for about 4 months now, are there even any issues with this problem? Is it something that needs to be fixed?

Try update the BIOS to F14 ( 8/23/12), if you want try the beta BIOS, F15o or F15q, for me I will not try those. Because the b2 error code is the "legacy option rom initialization", which related to the BIOS.

So just update the BIOS by using the gigabyte @BIOS, recommend to use the 2nd method: Update the BIOS without Using the Internet Update Function.
How to http://www.gigabyte.com/webpage/20/images/utiltiy_atbios.pdf
1) install the @BIOS. 2) download the BIOS into the USB. 3) Run the @BIOS, and choice update the BIOS from file, then follow the screen step by step to update the BIOS. After the update, make sure boot into the BIOS to double check the boot order, or other setting like the storage mode ( IDE, AHCI, RAID), just make sure which one you used, because the BIOS setting will be changed to default after the update.

Alright, I've been very busy and only just recently was able to get around to this. I've downloaded the BIOS update and have it on a USB drive, but I'm hesitant to use @BIOS, as I've read it's known to have issues and potentially kill( brick?) mobos. Is that reputation at all founded? Does @BIOS have significant risks at this point, or did it just previously have issues that have been fixed?
Thanks.
As far as I know, Q-Flash is the alternative to @BIOS, but that isn't working, as the BIOS splash screen keys are unresponsive and so I'm unable to access anything.

Also - I don't even know how much of a problem this is, as I have been using the computer for 2 or 3 months with this issue and, seemingly, nothing detrimental has happened in that time. The only error I got was an incompatible x64 error having to do with NvidiaBackend, but that hasn't persisted.
Any help would be greatly appreciated.

I closed your other thread. Please continue in this thread, not create multiple ones for the same issue. Thanks.

I had the exact same problem as you and I solved it by updating the BIOS to F14. It was intimidating but easy. You have to use integrated graphics (remove dedicated GPU and its power cables with the PC power off and unplugged) to look into BIOS, or you can press the END key to enter Q-Flash instantly. Then select the BIOS from your USB (has to be FAT32 format I think, USB can have other stuff on there too). If this file is a .exe file type, you have to extract the files first, then you'll see the proper BIOS file in Q-Flash. In a couple minutes you should have it updated, and can power off. Then turn off and unplug power supply, reinstall GPU and its power, and switch video cable from integrated graphics to GPU, boot, should be fixed!
