'0E' error with 'above 4g decoding' using nvidia titan rtx

I get an ‘0E’ error when enabling above 4g decoding in asrock 3.5 bios. I am using ubuntu with 2 titan rtx. Does anyone have any information on this?

Thanks !

Sounds like a bios bug, please try disabling CSM.

CSM is disabled.

I presume “0E” is displayed in the lower right corner on the monitor or on the mainboard’s diagnostic leds on bios POST? You can only ask ASRock for further assistance in that case.

Yeah, I have tried contacting them. They responded once, and have yet to respond since. Thanks
