I am primarily attempting to get this RAM working in Debian. I also have Windows installed, but it is not my primary operating system. The RAM works fine in Windows with MSI Center, but it does not work in Windows with OpenRGB or Linux (or SignalRGB if that means anything). I have UDEV rules installed in /usr/lib/udev/rules.d/ and have the modules i2c-dev and i2c-piix4 loaded. I also added the output results of sensors-detect, OpenRGB in verbose mode, I2CSniffer below.

I2CSniffer Log File:

OpenRGB Log File:
