Please explain SPD Not Detected

I would like to see the contents of the SPD memory slots via decode-dimms, but there is only support for up to 4 slots in the Linux kernel I2C

Model Number Example: SPD 4-20MA PRG -BL SLOT 56mm 28mm 28mm Each SPD order comes with

volatile slot If the above manipulations did not help, try setting the memory to DDR3-1333 or lower and set the timings and voltage according to its SPD spec

can you buy a slot machine I have an Asus laptop and even though I have about 8GB of RAM installed, both of the SPD slots are empty?
