GA-Z68X-UD3H-B3: Stuck on splash screen with new 980 GPU using UEFI beta bios

[zotune]

Hi, I have the GA-Z68X-UD3H-B3.

I was using the official beta U1L(UEFI BIOS) for a while, but when I got an NVIDIA 980 from MSI, it wouldn't boot (stuck on splash screen).

So I had to revert to the non-UEFI F12 BIOS. I contacted GIGABYTE support and they responded with the following:



Is there any way this can be resolved using UEFI bios?
Any help would be greatly appreciated

I'd also like to add that I find those Etron EJ168 USB3 ports useless.
After installing the custom drivers, I usually get blue screens or computer starts freezing. USB 3 devices often don't even work.

Kind regards
Mikael

Greetings,
Keep in mind UL1 is beta
F12 might be a better option for you as it already includes support for Ivy

Windows 8/10 will run, but without Secure Boot and no GPT support.  If you need these, I'd consider a platform upgrade to better support your video card investment.

So that we have the full picture. 
What board rev...?
What CPU are you running (Sandy or Ivy)?
What OS?

EDIT: This modified UEFI BIOS (GA-Z68X-UD3H BIOS U1l mod) boots with my GPU, I cannot believe it

Sandy Bridge

According to the bottom left of the motherboard I have rev 1.3

I'm pretty sure I tried Crossfire once and I could not get the second card to work with UEFI bios, it was first when I got the 980 that I tried a downgrade

It's stuck before OS starts to load

That is great you got the card to work but the card or cards are only running at 2.0. Plus if you put in a Ivy bridge CPU then you will get it to run at 3.0. Plus one other thing is if you run SLI.

The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated with a PCI Express graphics card, the PCIEX16 slot will operate at up to x8 mode.

Any body can do what they want. But I have agree with shadowsports with that board you are really putting good money into a old board.

No I actually looked into that and there's only like 2 fps difference, even if you have only x8

For the majority of games, there is no significant performance difference between x16 3.0 and x8 3.0 (and x16 2.0, which offers the same bandwidth). The average difference is only 1%, which you'd never notice. Even such bandwidth-restricted scenario as x16 1.1 or x8 2.0, offered by seriously old motherboards, only saw a small difference of around 5%. The same goes for x4 3.0, which is the bandwidth offered by the x4 slots on some recent motherboards. It's worth noting here that not all x4 slots are wired to the CPU. Some of the cheaper motherboards have their PCIe x16 (electrical x4) slots wired to the chipset instead of the CPU, which could severely clog the chipset bus (the connection between the CPU and the chipset, limited to a mere 2 GB/s on the Intel platform). Refer to the block-diagram in your motherboard's manual.

Real performance losses only become apparent in x8 1.1 and x4 2.0, where the performance drop becomes noticeable with around 15%. We also tested x4 1.1, though of more academic interest, and saw performance drop by up to 25%, an indicator that PCIe bandwidth can't be constrained indefinitely without a serious loss in performance.
