Each cpu has 2 physical banks (1 Even & 1 Odd bank ) with 4 DIMMS each

Each physical bank has 2 logical banks

B0: Group 0 is the Even bank (Note the Even bank DIMMS end with a "0")
B1: Group 1 is the Odd bank   (Note the Odd bank DIMMS end with a "1")

L0 is the front of all 4 DIMMS of the physical bank B0
L2 is the back  of all 4 DIMMS of the physical bank B0

L1 is the front of all 4 DIMMS of the physical bank B1
L3 is the back  of all 4 DIMMS of the physical bank B1
