1080TI works only if connecting the cable after boot

[PapaBearr]

Hi everyone,

 

I`ve finally built my first PC, however I`ve ran into some problems.

I can use my GPU only and only if I connect the cable to it, after I boot the PC using the on-board graphics.

If I don`t use the on-board graphics, I get the white Asus Q-led which is an error for VGA.

 

The GPU is fully seated, because once I boot up windows using the on-board GPU, and change the DP cable to the GPU itself, I`ve ran FurMark for 10 minutes w/o any issues.

 

I have tried the following:

 1 -> reset CMOS

 2 -> try 2`nd PCI slot

 3 -> Move the M2SSD to a different slot so that it is not on the same lines as the first PCI slot
 4 -> Change configuration of the PCIe in BIOS from auto to gen3 or gen4.

 5 -> This is where things get really strange. In the ASUS BIOS I have tried setting the primary display to PCIe, however every time I do that, and change the cable to my GPU before boot, I get the same white LED. Now, after I go for the on-board video and check BIOS, the settings get reverted automatically to CPU. I have tried setting it to Auto, and the same things happen. I`ve seen that other people encountered the same issue, and I tried a lot of bios configurations and nothing worked... Also, I have the latest stable BIOS firmware, so that should not be an issue. 

 

My build:
Motherboard-> ASUS TUF GAMING B660M-PLUS WIFI D4 
RAM -> Kingston FURY Beast 16GB DDR4 3600MHz CL17 Dual Channel Kit
PowerSource -> Seasonic Focus GX, 80+ Gold, 650W
GPU -> ASUS ROG-STRIX-GTX1080TI-O11G
SSD -> HP EX900 1TB PCI Express 3.0 x4 M.2 2280

CPU ->  Intel Alder Lake, Core i5 12600K 3.7GHz

Any help would be more than welcome.

Thank you !

added CPU

Welcome to the forums!
Is the GPU working properly - first time using it or have you tested it prior? Does it work in another PC if you have one?

@Mel0nMan hi, and thank you !

GPU works properly, no issues at all after booting up, stable w/o any crashes, as long as I do not shut down my PC..... The important part being shut down, because if I put it to sleep, it boots back perfectly fine, that`s why I was thinking it might have something to do with the BIOS.... also I`ve added the CPU info as I forgot about it.

I`ll try to test it on a different PC as soon as possible.

Try using the Nvidia Pascal UEFI patch tool.  I don't have the link.  Google it.

Hi, tried it, did not change anything.
I`ll try to test the setup with a HDMI cable asap as well.
Thank you!

Hello are you daisy chaining your power cables to the GPU or are they separate? They should be 2 separate cables to power the card.
Finally, Are you able to try DisplayPort instead of HDMI?

No daisy chaining. 
I have one cable which runs from the PSU directly to the GPU.

Currently I`m using DP, I`ll try HDMI later as I don`t have a cable yet.
