Hello,
Same issue, i have an Asus X570 motherboard. Works fine with the OpenRGB docker. but my HyperX RGB Ram isn't detected.
I tried the "modprobe i2c-piix4" and "inserted acpi_enforce_resources=lax" to the kernel command line, but it doesn't change anything.
Apparently the PIIX4 driver needs to be patched in unraid, when it comes to patching kernel, I don’t feel very confident. if anyone has a guide
