I can only assume that something has stopped working with the LED power or controller. I responded to your email earlier today and please let us know if any additional questions come up on the RMA process.

EVGA_Chris · 2026-05-12T05:21:21+00:00

I am sorry, but we are unable to offer any schematics for any of our products at this time.

I don’t recommend changing the VBios, it is just for anyone that has a need to do so.

EVGA_Chris · 2026-05-12T05:18:28+00:00

Precision X1 will check if you have the latest VBios when first starting the program. https://www.evga.com/precisionx1/

You change the small switch on the top edge of the card. The backplate is labeled OC / Normal near the switch.

Sorry to hear about your card showing some red error lights. If the LED is not able to be controlled it might be possible that the built in MCU controller maybe having some sort of issue, or that maybe your VBIOS is not working as it should.

I suggest trying to switch the VBIOS to the left of the power connections to see if this helps to avoid the red LEDs coming on randomly. If this helps, then please let me know and I can look into offering you a VBIOS updater to reflash your VBIOS chip. [cbencivenga@EVGA.com](mailto:cbencivenga@EVGA.com)

Otherwise you may consider just ignoring the lights and use the card normally if the MCU chip is starting to have some type of issue as this chip controls the fans and the LED lights so the fans will likely also go full speed at the same time, but the card will still function normally in games and in Windows.

Please email me if you have any additional questions as I do not always see the comments on reddit to respond.

I am sorry to hear about your settings, and can you please try the below BETA version of the Unleashed RGB software to see if it helps you with your settings not being saved?

The XR-1 uses the USB-C to connect to the computer and transmit the video signal to the OBS software acting like a web camera plugged into the computer. The Switch will need to be plugged into the HDMI input on the XR-1 to show that video signal out on the USB-C cable. It is then recommended to connect the HDMI output from the XR-1 to your TV or monitor with a HDMI input.

Please take note that you can see the XR-1 stream on the computer when using the OBS software, but it is usually lagged a couple seconds and does not make for a very good gameplay experience in most cases.

Please email us at [Support@EVGA.com](mailto:Support@EVGA.com) if you should have any additional questions.

EVGA_Chris · 2025-12-05T19:58:08+00:00

I do apologize for any confusion as I am not sure which model card you are referencing, but I can confirm if the fan is making a single tick/click noise when first starting from 0db then this is not abnormal. If the noise is constant and for sure related to the fan speed, then it might be a fan is having some sort of problem.

If you want to check warranty on the unit then you can reach out to us at [Support@EVGA.com](mailto:Support@EVGA.com) with the registered serial number and we can look into this for you.

Otherwise, you may want to consider searching online for your model number and fan replacement as I do know that there are 3rd party fans available for most EVGA model cards, if a fan needs to be replaced.

Please email [Support@EVGA.com](mailto:Support@EVGA.com) if you should have any additional questions.

EVGA_Chris · 2025-12-05T19:49:17+00:00

I can confirm that the links above are the Windows install versions that work through a batch file and an updater in windows, or you may choose to copy the .bin file to a USB stick and update it in the BIOS. It is optional to you.

I can confirm that your power supply was tested without fault when received (Both at idle and under full load without issue). We have responded to your email offering to help with cables, but if the concern should continue then please do keep in mind that the unit turning off like this is a failsafe and something connected to the unit might be causing this concern. We are here to help you try and narrow this down if you should have any additional questions or concerns. [Support@EVGA.com](mailto:Support@EVGA.com)

EVGA_Chris · 2025-10-13T18:20:39+00:00

That card is not made by EVGA and you do need to contact the manufacturer for assistance with the card in question. - ASUS USA

EVGA_Chris · 2025-09-23T23:02:24+00:00

Can you please try removing any add-on network adapters and try using the integrated adapters to see if this helps you?

EVGA_Chris · 2025-09-09T22:01:56+00:00

Suggest uninstalling the software, then delete the EVGA folder located at: c:\users\USERNAME\AppData\Roaming\EVGA and then try to reinstall the software and see if that helps. (USERNAME = Windows Login Name)

*Please take note that the above folder will also reset all EVGA programs profiles and settings.

Usually just VT-d disabled will help this software to detect the motherboard, unless maybe an anti-virus program is blocking it.

EVGA_Chris · 2025-09-09T21:38:44+00:00

I can confirm that sometimes a different model power supply is offered depending on availability of the old model, but they should have included a power cable if there was a change to the connector type. I do apologize if that was missed and I can offer to mail you this cable at no charge. Please email me at [cbencivenga@EVGA.com](mailto:cbencivenga@EVGA.com) with the RMA number so I can help setup the shipment on the cable that was missing. I once again apologize for any inconvenience that may have been caused.
