GPU error 43

[Nocturney]

Hey,

I know this is not the GPU section, but I assume it is not a GPU issue at all.

For some strange reason my system doesn't properly recognize any GPU except one. I have change/tried almost anything possible.

 

CPU : AMD 3960X

RAM : 4x Viper Steel Series DDR4 16GB 3000MHz (Tried at stock / 3000 / 3200)

Motherboard : Asus Zenith II Extreme (non Alpha)  /  Gigabyte TRX40 Aorus Extreme (Rev. 1.0)

PSU : EVGA G2 1300 gold / Corsair AX1600i titanium

Case : Lian Li O11d-XL (checked also outside of the case..)

Cooler : Arctic Freezer TR50 (currently, had same issues when tried a custom loop)

(If relevant..) Storage : 2x Silicon Power 512GB NVMe M.2 PCIe Gen3x4 (RAID0) + 2x Seagate BarraCuda 8TB

GPUs tested : Asus Strix 970  /  2x Asus 2060 Turbo  /  Asus FE 1080ti  /  MSI 1080ti Armor OC

 

No matter what I tested, my PC only recognizes and works with the GTX 970. Any other card wasn't working in Windows (error 43), and on the Asus board the GPU info in BIOS was always shown as invalid.

Tried reinstalling windows, DDU, diiferent boards and PSUs, all possible BIOS settings and the default, all possible PCIE slots, Even thought that maybe there's some weird case issue that prevented the card from seating properly so I tried a vertical mount (Phanteks PH-VGPUKT_02), tried to put 1 card, 2, 3 and in all possible combinations.

Nothing helped, same result all the time.

The GPUs by the way work perfectly fine on another PC, so they're ok..

 

 

What could possibly cause this ? 

Am I dealing with a CPU issue ?

Did you clear CMOS when you swapped out GPUs?

Yes, I did

Anyone have any idea ?

I'm in desperate need of help with this issue

So you keep installing windows in legacy mode? Is that what I'm reading? Have you tried UEFI mode, which all but the 970 need to operate correctly?

My Windows installation drive and the boot drive are both formatted as GPT for UEFI,

Checked the Windows system information and it shows that BIOS Mode is UEFI, not legacy.

I also checked the Windows setup log to make sure - Detected boot environment: EFI

What Am I missing.. ?

Not sure, Error 43 generally means the video card is bad. I'm trying to doubt you have 4 bad cards and the 970 is your only good working card left. So that's why I had asked the question.

The weirdest thing is - when I initially start the process : plug the 2060 / 1080ti, clear cmos, install Windows (UEFI, CSM disabled, no secure boot..), boot and install all needed drivers -

At first 2-3 boots everything is fine, GPU is working, and suddenly at one of the reboots everything seems to take much longer to post, and then I get back to the "faulty" state with error 43 and very low resolution. And only replacing it with the 970 gets everything back to normal.

As if the BIOS injects something to the GPU or changes something about it's configuration 

Same result on both motherboards and I even tried few times to reflash BIOS or try an older version.
