Had SC 672 from memory dimms but on different models to this, I would start there

Maybe controller or BICU after that

On these modern controllers memory, hdd or even NVRAM can cause this.

Before I replace a controller, I first disconnect the HDD, then restart the machine, then do the same with different RAM, and only then if the code persists do I replace a controller, as these are very pricey the side of the world.
