As I'm currently testing my memory with a single stick I double checked the compatibility list, except for the last letter the model is in the list.
BLS8G4D240FSA is in the list where I have BLS8G4D240FSB.
Looking closer to the memory compatibility list I noticed the density being at 8GB, I ran the system on 16GB, but I'm not sure what density means. Translating to my native language it means something else than what they mean because the translation to my native language does not come close to something related to hardware.
Module Supplier, Density, # of Ranks x DRAM devices, Module P/N., SS/DS, Chip Brand, Timing, Voltage, Memory socket support 2 & 4
CRUCIAL, 8GB, 2Rx8, BLS8G4D240FSA, DS, Micron, 16-16-16-40, 1.2v, v & v
