DRAM on x470 not writing over i2c
Hey there, I wanted to see if I could get a set of Aura-supported Kingston RGB DRAM on a Asrock x470 running with OpenAuraSDK and contribute back, but I wanted to test run them first writing from the i2c bus directly for static. Unfortunately I run into Error: Write failed whenever I try to access the address.

I2C Block Read no I can see what I assume to be the Aura chips on 0x71 and 0x73 (4 sticks 2 channels perhaps?) and the SPD at 0x50-0x53, but whenever I attempt to write them with i2cset, they always fail:
[root@slotterarch ~]# i2cdetect 0
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0.
I will probe address range 0x03-0x77.
