Arc a750 not working

[Boune]

Hello, I just bought an intel arc a750 for my pc.
The problem is after plugging in the card there can be those two following scenario:
The first, the pc do not boot, I can’t even access the bios and the only thing happening is that I have a black screen with a solid white dash, also the EZ debug led for VGA of my motherboard is on. And peripherals not working

The second, I tried without plugging monitor, the keyboard and mouse’s lights are on but when I plug a monitor after that, there’s no signal. And I can’t hear the boot sound in my headset


Here is the full confit:
Motherboard : MSI B365M Pro VDH
Processor : intel i5 9400f
Ram : hyperx 2x8go 2666mhz
PSU: Corsair cx650
A Samsung 500gb sata ssd

I tried with another psu (a 650w advance) and it didn’t work either
When I plug my former graphic card, everything is working perfectly, it’s a gigabyte nvidia gtx 750 ti.
I removed nvidia drivers from my pc

My bios version is E7C39IMS.142 which is at this moment the last update
Resizable bar is on
Fast boot is off
Bios is in UEFI mode

Follow the steps described in the following articles:

https://www.intel.com/content/www/us/en/support/articles/000092760/graphics.html

https://www.intel.com/content/www/us/en/support/articles/000094366/graphics.html

However, I noticed that you are using a 9th generation processor and that might be the source of this issue as arc graphics needs a minimum of a 10th Gen Intel® Core™ Processor. For more information, please see this link: https://www.intel.com/content/www/us/en/support/articles/000091128/graphics.html

I tried the things in both articles, it's still not working, got the exact same behavior.

I read online, that the reason for the minimum of a 10th gen was for rebar, which can now be enabled on 9th gen after updating the bios. It shouldn't be a problem then except for a little less performance, but that shouldn't prevent the graphics card from working.

I had the same problem.

ARC Graphic cards couldn´t handle the PCI 3 speed itself.

So you must enter the bios

set the pci 4 speed to PCI 3,

and I think your problem is solved.

I verified in the bios, and my pci is set to gen 3. My motherboard don't have gen 4 pci-e.

The system works best when you meet the recommended system requirements. I understand that you may prefer to use an older processor, but unfortunately, that is not possible. Please follow the recommended requirements so that you can have the best experience with the system.

Hello  Boune !

@Senkuchan 

@Uwe_59 

FYI guys. Don't know if it's still actual, but might be the case, please if you can, add this into issues solutions and knowledge base.

So here is the reason of this issue and actual solution, which doesn't involve things like reinstalling Windows, etc:

Many user applications such as Twitch Studio, are adding an additional overlay layers to Vulkan API. These layers are often badly managed and outdated, and as result, they're causing whole Vulkan API to stop working completely with Intel Arc drivers, causing issues like described with games which using Vulkan API, like No Man Sky. In case with Twitch Studio for example, the target Vulcan API level is 1.1, while Vulkan API Runtime shipped with Intel Arc drivers is of level 1.3, and Vulcan Runtime is not able to start while this overlay is present. On my system it was Twitch Studio overlay which was blocking Vulcan Runtime from working completely so no games which using Vulkan API was able to run.

So how to diagnose and fix the issue:

1. Open up Terminal from Administrator, for example by right-clicking on Start button and selecting "Windows Terminal (Administrator)"

2. In the Terminal window, input "vulkaninfo" and press Enter.

3. In normal case when everything works OK you should get a huge listing with Vulkan Instance Version, Instance Extensions, layers, capabilities, etc, etc. But when some of the layers which are present in the system break the functioning of Vulkan API, instead of this huge listing, all you get would be just 4-5 lines with errors which will mention what some layer requires runtime version 1.1 or 1.2 and so not able to start as version of runtime in the system is 1.3.

4. To solve this issue in this case, open Regedit and check these two keys

HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\ImplicitLayers

HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\Vulkan\ExplicitLayers

in this key you will see registry entries for all the third-party Vulkan layers present in the system as REG_DWORD parameters. Now all you need to do is simply find and delete the entries for layers which was mentioned in vulkaninfo errors and are blocking the Vulcan Runtime from functioning properly.

5. After doing so, again in the Terminal window, input "vulkaninfo" and press Enter. Now if you have deleted all the outdated layers, you should get a full Vulkan information listing. After that all games will be able to function.
