A770 fan and led stoped working

[JGarner]

New computer as of august 2023: Ryzen 9,  64 gigs RAM, MSI Motherboard, and my A770. Second self build

Installed: intel arc control, RGB controller, and most current driver at the time (gfx_win_101.4669).

computer was working great, played steam games fine, tried to play Starfield and it didn't work. eventually went back to another game and found the FPS to be very low. at this time the RGB and fans had stopped working and it was overheating at 90 degrees C.

through the next week i tried to reload the programs, drivers (gfx_win_101.4826) and arc control both worked. however the RGB controller does not detect the a770, and will not install. 

the a770 seems to work in every other way, it simply has no fan or RGB.

Thank you for posting on the Intel®️ communities. I understand ho frustrating is for you to know that the Intel® Arc™ A770 Graphics is not working properly, I will be happy to help you.

To have a better idea of the issue, please answer the following questions: 

• Is it a Intel® Arc™ A770 Graphics Limited Edition or is it another model?
• Was it working before?
• What is the issue that you have with Starfield?
• What is the other game that was tested?
• To know your hardware an software information , attach the report for the following tool Intel® System Support Utility for Windows (SSU), you can find the steps on the link How to get the Intel® System Support Utility Logs on Windows.

it is limited edition

it was working for a week or so before the issue started

Starfield wouldn't launch, which was apparently not unusual for the Steam version

Armored core 6 and War Zone 2 worked fine

while playing Warzone 2 is when i noticed the lag and subsequent GPU issues, nothing out of the ordinary happend before the issue started as far as i could tell

Hello JGarner,

Thank you for your response, and for shearing the information, that helps a lot.

I see you are reporting several issues, in this thread I will help you with the led issue to keep the threads organized and help you in the best way, for the other issues please open a thread per issue.

Please answer the following questions to start with the troubleshooting:

• For the LED to work, it needs a 1 x 3-pin cable, is it connected properly? If so, try removing and reconnecting it.

Let me know the results

The LED worked for a week before it stopped. I had not changed where it was plugged into before it stopped working. I have reseated the LED connector with no change in status

Hello JGarner,

Thank you for your answer, and for all the information provided.

Let's try the steps below and check if the behavior changes:

• Clean install the graphics driver to version 31.0.101.4826 with Display Driver Uninstaller (DDU). For guidance, How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver.
• Reset the Fan curve to automatic in Intel® ARC™ Control.
• If the issue persists, clean install the graphics driver to version 31.0.101.4672 using DDU? Is the same behavior present in this driver?

Hello JGarner,

Were you able to clean install the graphics driver and reset the Fan curve to automatic?   

Let us know if you still need assistance.

Yes I did as you asked. i used DDU twice, once on 31.0.101.4672, and on 31.0.101.4626 as well as setting the fan curve to automatic. 

none has had any noticeable affect on the performance of the a770.  the RGB still doesn't work and the fans are motionless.

also, if i try to install the intel ARC RGB controller it does not recognize the GPU, see attachment...

Hello JGarner,

Thank you for your time.

We still working on the investigation, and I have a question to clarify the situation, did the fan start working again? If so, what fix it?

I see in your previous response you only mentioned the results about the RGB.

No, the fans and RGB have been off through all the suggestions. I will also add I'm also working with another tech at the same time. Not sure how my question got double teamed but...  see attached
